Why Angular?

When setting up your initial Angular development environment using the Angular CLI, you will realize how much the CLI has now become essential.

This is because we need so much more setup today when compared to what we had before - and this is the case not only for Angular but also for any other equivalent ecosystem.

A couple of key questions

In this new world of module loaders, advanced build systems that we no longer set up ourselves from scratch, and where everything is transpiled down to plain ES5 Javascript from higher level languages, it would not be surprising if at a given point you would ask yourself:

Do I really need all these tools and dependencies? Isn't there a simpler way, what is the advantage of doing thing this way? Why Angular?

You might even ask yourself, why not do everything in a previously existing technology, like jQuery for example?

There are many use cases that are still today well solved by that approach, but that lead us to the question:

In which way does Angular improve upon previously existing technologies?

What problems does Angular solve in a fundamentally better way, and why is it better?

Everything happens under the hood

Let's find out! The key thing about the main advantages of Angular and MVC is that everything happens so much under the hood that it's sometimes hard to realize that the advantages are even there.

In order to understand the benefits of the MVC approach, we are going to build a small application in for example jQuery, and then build its equivalent in Angular - and the differences between both will quickly become apparent.

The goal here is not to compare Angular with jQuery, but to compare the MVC approach to frontend development with pre-MVC approaches.

jQuery is used here because it's a very well known example, and it's still very useful today for many use cases.

An example of a jQuery Application

To understand the advantages that both Angular and MVC bring, let's give a simple example. Let's start with a simple application that just displays a list of lessons on the screen.

The lessons will be loaded via an HTTP GET request from this url. Actually, this data is coming from Firebase via its alternative HTTP API (learn more about it in the Firebase Crash Course).

And this is what the list of lessons will look like:

What is the Model in MVC?

As we can see, the data above is simply a Plain Old Javascript Object or POJO.

Those unique identifiers that you see are Firebase push keys, more on them on the Angular and Firebase Crash Course.

The JSON object above is the data of our application, also known as the Model, and we would like to display it on the screen - therefore we need to generate HTML based on this Model.

So let's start by doing so in jQuery first, and then implement the same logic in Angular.

What does a jQuery application look like?

Lets build a small jQuery application to display this data (the application is available here):

So in our jQuery application, the first thing that we need to do is to query our REST API backend by doing a jQuery Ajax request:

Notice that we called Object.values(), this was so just to transform the returned result which was an object (and therefore a key-value dictionary) into a list of lessons.

Note: the order of the lessons is not guaranteed to be preserved

With this we now have our Model in the browser, ready to be displayed - the list of lessons. As you can see, we did not send HTML over the wire from the server back to the client, instead, we did a request to the server and returned only the data.

This is a critical notion because the HTML is more than the data: the HTML is a particular representation of the Model, that we can call a View, and the same data could have multiple views.

The Model vs View Distinction

The same Model (the list of lessons) that we have shown above, could have multiple Views. Here are a few examples:

As we can see, one View of the model is an HTML table, but another possible View could simply be the total number of lessons.

Also, each lesson itself can be used as a Model, itself with different views: we could have a lesson detail screen showing all the detail of a lesson, of just a row in a table - showing a summary of the lesson.

How to Display the View using jQuery?

We now have the data on the frontend, so we need to use it to create the multiple Views. Here is how we could generate an HTML table with a list of lessons in jQuery:

Reviewing the jQuery application

As we can see, we are writing quite some code to take the model, and transform it into the multiple views of the data. We can see that this code although straightforward to write, has the following characteristics:

This code is not very readable, its mixing several concerns

this type of code is not very maintainable

this is a lot of code, it makes for a significant portion of our application!

we are building HTML by string concatenation and then passing it on to the browser, which will still have to parse it

This last point is important for the comparison in terms of performance, more on this later.

Enter Angular, how is it different?

So now let's rewrite this part of our application in Angular (the application can be found here).

This is only the key part of the application, there would be an Angular CLI folder structure around it, but its standard and generated for us. The Angular equivalent would then be the following:

So let's break this down and compare it to the jQuery version:

we have here a class that knows both about the data retrieved from the backend and the HTML template needed to render it

the HTTP request is being made via the Angular HTTP module

the data is stored in a variable called lessons

But the biggest apparent different is that there is no trace of HTML in this code.

The Angular View Generation Process

So how is the HTML being generated then ? Let's have a look at the app.component.html HTML template file:

As we can see, this is where the HTML is kept now. And it's separated from the component code as it sits in a separate file altogether.

Notice that this template does have some expressions and syntax that does not look like the HTML that we write every day, such as for example:

the ngFor directive that loops through the list of lessons

the {{lesson.description}} expression, which is how we can output data to the view

These expressions are how Angular ties the data and the view together.

The MVC Terminology

Based on the Angular application above, lets then define some terms:

the plain JSON object is the Model of our Application

the template (or the output of its processing) is the View

the Angular AppComponent binds the View and the Model together

Angular vs jQuery - comparing the two versions of the application

Now that we have two applications written in both jQuery and Angular, let's start comparing them.

Already in this initial stage, we can see several differences:

the template of Angular is much more readable than the jQuery code

the AppComponent code does not generate HTML, it only fetches the data from the backend

The biggest difference just looking at the code is that in the Angular version there is a separation of concerns that does not exist on the jQuery version.

In the Angular version, the Model and the View are clearly separated and interact via the AppComponent class, while in the jQuery version all of these concerns are mixed in the same code.

But that is not the only advantage of using an MVC framework: the differences will become much more apparent if we start modifying the data.

What if we now Modify the Model?

The separation of concerns of the Angular version is a great thing to have, and essential in a larger application.

But there is more going on in this small example that is not yet apparent: what if we now want to update the Model? Let's say that now we want to change the title of each lesson, to include the sequential number of the lesson.

To make it simple, let's do this in response to a button. This is what the jQuery version would look like:

So let's break it down what is going on in this new version of the code:

we have extracted the code to generate the HTML into a separate function called generateHtml(), so that we can reuse it (see the function below)

we have stored the lessons data inside a module so that it does not pollute the global scope

we have added a click handler to a button, that modifies the data and then calls again the generateHtml() function

The function that we created for reusing the HTML generation logic looks like the following:

The problem with this type of code

It might not look like it, but this code is really fragile and hard to maintain: one single quote in the wrong place and we will still have a valid Javascript string that will look completely broken when rendered by the browser, as it's not valid HTML.

This is the type of code that we don't want to have to write ourselves: it's really brittle, even though it might look straightforward at a first glance.

Comparing with the Angular version

Now let's have a look at the equivalent Angular version of this code:

The updateCourses function is being called by a button that we added to the template:

Reviewing the Angular data modification version

Like its jQuery counterpart, this version of the application is also adding an index to the description of each course (have a look at these ngFor features for an alternative).

What we did in this Angular version was: we simply updated the Model, and Angular has automatically reflected the Model modification directly in the View for us!

We did not have to call an HTML generation function, apply the HTML in the right place of the document, etc. This is one of the killer features of Angular:

we did not have to write any Model to View Synchronization code manually, that synchronization has been somehow done for us under the hood!

So how does this work?

Angular keeps the View in sync with the model for us at all times via its transparent change detection mechanism.

The way that this works is that Angular will automatically check the Model, to see if it has changed and if so it will reflect those changes in the view.

But besides the separation of concerns and the automated detection of changes and synchronization, there is something else fundamentally different between the jQuery and the Angular versions.

Maybe The Biggest Difference Between Angular and jQuery?

We cannot tell just by looking at the Angular code because it all happens transparently, but one of the key differences is that unlike jQuery, Angular is doing the document modification in a much more efficient way than the jQuery version:

Angular is not generating HTML and then passing it to the browser to have it parsed, instead Angular is generating DOM data structures directly!

This works much faster than building manually HTML and then passing it to the DOM for parsing. By building DOM nodes directly, Angular is bypassing the HTML parsing step altogether. So the browser simply takes the ready to use DOM tree and renders it to the screen.

And more than that, it will do so in an optimal way, by trying to change just the HTML that absolutely needs to be changed:

Angular will not replace the whole DOM tree each time, it updates the DOM in an optimal way, depending on what parts of the Model have changed

How is Angular rendering the View under the hood?

In order to understand better what Angular is doing under the hood, let's do the following: let's go back to the jQuery version and try to do something similar to what Angular is doing - direct DOM manipulation.

The click handler code would now look something like this:

So as we can see we are using directly the DOM API to remove the nodes under the lessons Div. Then we are replacing the table with a new table that was created using the generateDomTable() function.

And this is what that function looks like:

If you would like to see this in action, clone and try locally the two sample applications (one application in Angular and the other in jQuery).

The Advantages of the Angular View Generation Process

Actually, this is just a very rough approximation of what Angular is doing under the hood.

This function is regenerating the whole table, but what Angular does with its templates is that it will replace only the parts of the DOM tree that need to be modified, according to only the data that was modified.

So for example, if only an expression on the page title was modified, that is the only part of the DOM that will be affected, the list of lessons would remain unchanged.

It's just not practical to do manually what Angular is doing

And this is where it would become almost impossible and certainly impractical to do with jQuery the same thing that Angular is doing transparently under the hood.

Its simply not practical to write this type of Model to View DOM generation code manually ourselves like the generateDomTable(), despite the benefits of that approach.

For example, notice that the generateDomTable() function although it creates DOM nodes directly, it's not optimized and generates the whole table each time.

Summary and Conclusions

So let's summarize: the advantages of using an MVC framework like Angular as we have seen are huge, so let's list them one by one.

Separation Of Concerns

We can build frontend applications with a lot less code than previous generation technologies. This is because we don't have to write code that manually synchronizes the Model and the View - that code is generated for us automatically.

The code that we do need to write will be a lot more readable and maintainable, due to the clear separation of concerns between the Model and the View.

Transparent Model to View Synchronization

The synchronization between Model and View is not only transparent but its optimized in a way that is not possible in practice to achieve manually.

UI Performance

The View is modified by generating directly DOM object trees in a cross-browser compatible way, instead of by generating HTML and then passing it to the browser for parsing - this effectively bypasses the parsing step altogether.

The HTML still needs to be parsed, but it's done only once per template by Angular and by the browser each time. The parsing is done either at application startup time (Just In Time, or JIT), or ahead of time (AOT) when be build the application.

And this one of the main reasons why it's so worth to have a more advanced development environment like the CLI: because using it we can have all these features and benefits working transparently out of the box.

Also, the generation and modification of the view are itself done in an optimized way, meaning that only the parts of the DOM tree that have modified data will be affected, while the rest of the page remains the same.

Why MVC has become essential for frontend development

With Angular and MVC we can focus on building applications in a more declarative way, by simply defining an HTML template just like we are used to.

We can them bind the template to the Model data, and handle the data via a component class.

Is it doable not to use MVC ?

Choosing to not use an MVC framework means that we will have to keep the Model and the View in sync manually, which looks simple at first sight but very quickly we will end up with an unmaintainable program.

I hope that this gives you a convincing explanation about why we need an MVC framework like Angular, and this type of technology solves for us a large number of problems in a completely transparent way.

And why it really pays off to setup a more advanced working environment, to be able to enjoy all these benefits and great developer experience.

I hope that this post helped understand what are some of the key benefits of using a framework like Angular, and that you enjoyed it!

Angular is a front-end web development platform that operates as a JavaScript framework. Angular is not to be confused with a JavaScript library, like jQuery. Angular is similar to platforms such as Polymer, Aurelia and React. This open source framework was developed by Google under the MIT License in 2010 and has since received several upgrades and facelifts to keep up with the times.

# data[].attributes.attachment_link.readable_text
This JavaScript framework offers a robust collection of components that simplify the art of writing, altering, and using code.

If you're experienced in JavaScript-which you definitely should consider before trying to understand how to use Angular-then you know that this language can easily become a real tedious, copy-and-paste gig. The AngularJS framework reduces the amount of time developers spend writing JavaScript stacks, which speeds up the completion of monotonous tasks and frees up your schedule to focus more on the functionality and design of your creation.

For every application you design, there are several lines of code to be written, most of which you've holstered in your handy dandy Notepad++ for easy access. But it doesn't matter how quick you are on the ctrl+shift+v trigger, you're still spending an unnecessary amount of time compiling a JavaScript stack that someone else has already provided-that someone being Angular.

How many hours have you spent coding solutions to common problems associated with creating a responsive application? Reducing padding, leveling margins, condensing sidebars, centering text blocks, designing mobile headers and menus that are still readily available without complicating or disrupting the user experience?

The list is exhaustive, right? And it never seems to end. At the drop of a hat, Google can (and will) release another list of demands to weed out the spammy URLs and ensure websites are delivering credible, quality content. Just recently, web developers had to log in to the back end of every website they manage and set up a highly-visible disclaimer for using cookies. In case you haven't already noticed, there are countless websites that have failed to implement this new requirement in such a way that doesn't hideously disrupt the user experience on mobile devices. Most of these disclaimers, you can tell, were added begrudgingly by developers who didn't want to be bothered with another wave of Google's golden scepter.

Can you blame them? When you're writing your own code, even the smallest task can become an annoying inconvenience-especially if there's a hidden flaw in the code that takes you forever to resolve in order to make the application function properly.

Angular JS was designed as a way to simplify the tedious, repetitive, time-consuming task of writing code. This framework can make development a lot easier and faster-once you're familiar with how to use the program-which opens your schedule to new opportunities, new clients, and more profit.

With tech giants that like Microsoft and Samsung using Angular, the platform has gained a solid reputation. Over time, Angular has slowly been brought into the limelight, convincing big-name companies, such as Deutsche Bank, PayPal, and Upwork of its quality.

# data[].attributes.attachment_link.readable_text
Evidence shows that modern web frameworks like Angular are on the brink of overriding traditional frameworks like jQuery. Although it's easy to get caught up in Angular's popularity trends and near decade-long history, you might be wondering what drove Angular to be so popular and how top fortune 500 companies leverage this front-end web framework to their advantage.

With tech giants that like Microsoft and Samsung using Angular, the platform has gained a solid reputation. Over time, Angular has slowly been brought into the limelight, convincing big-name companies, such as Deutsche Bank, PayPal, and Upwork of its quality.

Whether it's a massive online payment system like Paypal using AngularJS for their checkout/transaction portals, or Delta airlines deploying Angular to display real-time airfare data, the number of diverse companies that use Angular has increased exponentially over the last decade.

In this post, you'll take a look at twelve, cutting-edge companies that use Angular in their present-day web app development pipeline, listed as follows:

Stay engaged and continue reading!

What Is AngularJS?

With the framework's initial release in 2016, it is now maintained by Google.

According to Angular's official documentation, Angular is more or less a structural framework for building dynamic web applications.

Angular lets developers use HTML as a base template language, allowing them to extend HTML's syntax to clearly and succinctly express app components with only a few lines of code.

By taking advantage of data binding and dependency injection, Angular eliminates excess code that developers would normally have to write.
Since this all happens within the browser, Angular is one of the most ideal partners to couple with any server technology.
How Companies Use Angular

Many companies use AngularJS as the frontend of their MEAN stack, consisting of the:

MongoDB database

Angular.js for front-side development

Express.js web app server, and

Node.js server runtime environment.

Core Features of Angular

Angular boasts an array of core features, making it a key competitor with the React framework.

These features are listed as follows:

Angular automatically synchronizes data between the model and view components.

This enables developers to seamlessly create interactive applications without worrying about manually pushing and pulling data.

For companies that use Angular, this translates to saved time and the cost of hiring an armed force of web developers just for the purpose of pushing and pulling data sources.
The Angular framework allows companies to develop progressive web applications (PWA).
By deploying PWA, developers can offer app-like experiences to their audience on their websites.

Angular also comes with their staple hybrid mobile software development kit (SDK) called Ionic.
By converting templates into clean semantic code, Angular redefines the modern JavaScript virtual machine Related reading: Vue.js vs. React: Which Is Better? .

Ionic allows developers to ship apps to the IOS app store, Google Playstore, and web application(s) simultaneously without having to hustle to create apps separately for each platform.

In the long run, this saves added time and effort, securing return on investment sooner rather than later.
Whether it's Angular's code reusability or dependency handling, the framework provides many business-level advantages.
Angular leverages hand-written code to another level through high-speed page loading times and optimal rendering capabilities.

Developers no longer need to exhaustively write separate code to link model-view-controller (MVC) layers.

Additionally, directives are isolated from the app code, minimizing development time.

What Are the Advantages of Angular?
This also means that clients can get what they want faster. Since Angular is open-sourced, companies that use Angular can rapidly outsource and secure assistance from vetted front-end developers. Ten years ago that would've been nearly impossible.
Popularly dubbed as the framework of "What HTML would have been if it had been designed for building web applications,"Angular spotlights technical and qualitative advantages that give it that extra edge amongst the ranks of web development frameworks.
You'll find that Angular's modular design capabilities and cross-platform architectures maximize sustainable development, so teams can deploy ready-to-use apps in no time.
Below are some of the top benefits of using Angular in your front-end development pipeline.
With Angular's modular code design and isolated components, developers can reuse code for new applications.
Built and Vetted by Google

Dating back to its initial release in 2016, each and every Angular version has been maintained by dedicated Google engineers.
This idea of reusability across small-scale and large-scale applications is what makes Angular a leader in the web app industry.
Google's continuous maintenance of Angular has established a huge community out there for individuals and organizations to learn from.

Efficient Design Architecture
Angular's noteworthy model-view-controller (MVC) architecture promotes faster development, testing, and maintenance in the software development life cycle.
In today's tech world, many companies that use Angular handle web apps with hundreds of features and components while still juggling page loading time and user engagement functionality.
But with Angular's integration of MVC logic, applications become easier to update, development time is faster, and collaboration between multiple developers is enhanced.

However, in 2020 we're seeing a massive upsweep of tech giants, with the likes of Google and Microsoft integrating Angular to manage their most prized web apps.
Industry websites of all kinds have leveraged Angular to their advantage, anywhere from airline customer transaction systems to some of the most popular email services.
Code Reusability

This allows companies that use Angular to effortlessly transfer features written in earlier applications to new version releases or entirely different web apps.

Reusability is particularly important as small and medium-sized companies look towards building large-scale enterprise applications.
With Angular, they were able to accomplish just that.
By integrating Angular into the front-end, companies can ensure that the scale of their applications meets the scale of their business demand over time.

Faster End-to-End App Development
Among the companies that use Angular, Microsoft took one of the boldest approaches.
MVC is a software design pattern that reinforces the web app development process.

The MVC architecture gained popularity with organizations for isolating application logic from the user interface layer and supports a separation of concerns.

Before MVC's inception, developers would normally struggle with integrating logic, and things would get extremely disorganized.
The free online web app features most if not all office features condensed into a single-page view, allowing businesses and users to collaborate on teams and create documents.
12 Global Companies that Use Angular

For example, Deutsche Bank's developer portal utilizes Angular to display relevant API information, whereas one of the world's most well-known email clients, Gmail, uses Angular to display its single-page inbox system to more than 1.5 billion active monthly users worldwide.

It's evident that Angular transcends all industries, catering its simple, ready-to-use components to global organizations.

The following list of companies that use Angular all had one common motivation - using and scaling web applications to fulfill the demands of their client base.

1. Microsoft Office

The massive multinational tech company, Microsoft, initially released Office in 1998. In April of this year, Microsoft sported 75 million daily active users.
Since Angular allows single-page data to be updated in real-time, Mixer employs the framework for essential game streaming features.
Microsoft Office's expansion into the 21st century was partly due to its efficient migration to the web.

In August 2014, Microsoft shipped two new standalone web applications that take advantage of the AngularJS framework by using the Office 365 API.

Fast forward to present-day 2020, Microsoft Office is now packaged with a free-to-use Microsoft 365 web application online.

2. Deutsche Bank

Deutsche Bank AG, a multinational investment and financial services company, uses AngularJS for the front-page of their developer portal.

Their developer portal features the Deutsche Bank API program, acting as an access point to millions of global organizations looking to integrate Deutsche Bank transaction systems into their web software.

3. Mixer
Whether you're reading an email, drafting a new message, or switching tabs, AngularJS handles every action within a single webpage.
Mixer is a free video game streaming website and service developed and released by Microsoft, ranked highly among similar competitors, such as Twitch and Youtube Gaming.

In contrast to other companies that use Angular, Mixer integrated it into a video streaming use case.

This includes hosting fast live streaming, commenting on streams, co-hosting from your own channel, and receiving alerts when channels you follow start live streaming.

4. Santander

Santander Bank initially organized its services in Spain, slowly establishing its principal market in the Northeastern United States since 2013.
This is because Angular can handle the publishing demands of journalism in the 21st century.
According to Santander's Global Tech and Operations page, Angular is employed by its team of over 2,000 people in seven countries to create web-based financial solutions.

5. Gmail

Since Gmail was developed as a single-page emailing application in 2004, it served as the perfect use case for integrating AngularJS.

Every time a user opens Google's mail service, the web app loads one single HTML page whilst dynamically updating information based on new messages or notifications.

6. Forbes

In April of 2020 alone, the subscription-based magazine giant, Forbes, pushed the limits by achieving 173.5 million page visits.

The publishing company promotes fast page loading time and responsive user experience by using AngularJS in its front end.
Ultimately, it's safe to say that Angular functions as the foundation behind PayPal's responsive mobile and web application experience.
With Angular, stories and articles can self-update seamlessly within seconds of publication for subscribers to view.

Forbes established a clear precedent as one of the large publishing companies that use Angular.

7. Upwork

Established in 2015, Upwork serves as the go-to freelancing platform for organizations and individuals to conduct business.

As of May 2020, Upwork has profited considerably, accumulating revenue in the range of $79 million to $81 million.

8. PayPal

Paypal Holdings, Inc. is a leading American company that operates a massive worldwide online payment system.
The Samsung Forward service page integrates Angular to enable visually appealing animations and mobile-friendly transitions that enhance the customer experience.
It supports rapid online money transfers and serves as a third party electronic alternative to traditional paper methods like checks and money orders.

PayPal uses Angular to architect dynamic web pages that support real-time feeds of PayPal transaction data.

9. Grasshopper

Grasshopper is a premier mobile application created by a team of passionate coders from Google's workshop for experimental products, Area 120.

The application helps beginners ease their way into coding by using fun and easy learning methods.

10. Samsung
The front-page of Overleaf's website, which includes a quick sign-in feature, incorporates Angular to optimize page loading efficiency and browsing public LaTeX templates.
Samsung has quickly established itself as a key multinational competitor in the electronics industry ever since its founding in 1938.

Although Samsung typically reminds us of physical hardware, they've created responsive front-page websites packed with Angular code.

Among the companies that use Angular, Samsung distinguishes itself as a chief leader in the electronics sector.

11. Delta

Delta Air Lines is one of the most competitive airline carriers in the United States, with the front-page traffic of their website ranked fifth in the travel and tourism category.
Angular is a universal framework with the ability to transform the functionality and interactivity of your web applications for the better.
Delta's website went all out with AngularJS. Instead of sprinkling it onto its airline web applications here and there, they deployed the framework onto its homepage.

Through its integration, Delta now allows customers to register flight info and perform advanced airfare searches with fast page loading speeds and comfortable user experience.
Here at Trio, our developers can get some of your boldest web development projects done, large or small. Learn more about how you can hire qualified Angular developers for your project today!
12. Overleaf

If you're familiar with LaTeX, you'll likely be familiar with Overleaf. Overleaf is a collaborative cloud-based LaTeX editor used for writing, editing, and publishing scientific documents/publications.

Conclusion

The first stable releases of Angular have only existed for around four years.

Let that sink in.

In less than a decade, Angular's globally branded reputation and association with big names such as Google, PayPal, and Microsoft, has established one of the largest web development communities.

If there's one takeaway from this article, it's this:

Single-page web apps like Gmail and Upwork made Angular work for them. In 2020, there is nothing stopping smaller enterprises from melding Angular with their existing tech stack.

In order to make Angular work for your business, you need senior-level web developers with expertise in creating and scaling web applications with JavaScript.

When Google launched Angular.js in 2009, jQuery was still the colossus on the framework market. We used it to enhance our applications with nifty UI effects, for seamless client-server communication and to brew coffee. Actually, most of us were quite happy for a while. But then our apps became more and more complex, and our tightly coupled components and interfaces turned out to be very hard to maintain.

Actually, most of us were quite happy for a while. But then our apps became more and more complex, and our tightly coupled components and interfaces turned out to be very hard to maintain.

With the rise of MVC frameworks like Backbone, Angular and Ember.js, things started to change. We realised that while jQuery has done an fantastic job in getting us to this point, we had stretched it to its limits. If we wanted to better understand and manage our fat clients, we would need to take a different approach.

Angular at Hanno

Here at Hanno, we have been using Angular.js on a few projects recently, and are quite excited about where things are going. Jon and I have spoken a lot about the benefits that Angular provides in a rapid development process like ours, and how it can benefit our clients.

We even came to the conclusion that narrowing our focus a little, to actively look to work on more Angular projects and build our expertise in it, could provide a lot of value for us and our clients. As more and more developers start to embrace it, and other great frameworks such as Ionic and Foundation for Apps begin to rely on it, it feels like a solid bet for the medium-term future of our work.

That's not to say that we intend to focus solely on Angular, but by choosing it as our "preferred framework" for now on new projects, and building up our expertise in it, we can work much faster and more effectively.

So, what are the actual benefits for you as a startup when using Angular? How can it improve your workflow and enable quicker iterations? And how does it make your team work faster and more efficient?

Here are the answers...

It's backed by Google

Being backed by the tech giant makes Angular very attractive for startups who want to minimise the risk of their technology stack becoming outdated anytime in the near future.

All of the core contributors are now working at Google so it's obvious that Google takes Angular seriously and it's not going to disappear anytime soon.

Some may argue that it's not good for a software product to be owned by a single company, but it also avoids unnecessary flame wars inside the open source community, like the one we saw when node.js got forked into io.js by its top contributors, which is a very unfortunate thing to happen when your startup relies on open source technology.

It allows decoupled API-driven development

From our experience, using Angular is a great way to work on front and backend code independently of each other.

The fact that all of the view templates are being generated on the client allow you to craft a user interface without worrying about the server stack at all. Instead, you can focus on building the UI, bringing in application data in one of the following ways:

Using data from an already existing data source, if an API has already been built out for you.

Mocking the data service. Because Angular relies on dependency injection, you can feed your app easily with dummy data and later replace it with the real data service.

When we worked with Mirror recently, their engineering team was focusing primarily on building out their API. We worked on the frontend and used their API and documentation to bring data into the web application we were building. Because we didn't have to set up any backend components, we could focus on the user interface design, while they were able to focus their resources on developing the business logic. The only downside was that we had to rely on a working internet connection all the time.

It's ideal for quick bootstrapping

In another project, we used Angular to quickly put together some UI components in the browser. Since a lot of application logic can be written in a declarative way by using HTML tags and attributes when you're using Angular, we hardly had to write any JavaScript in order to make that happen.

In this way, we were able to cover a lot of ground in a short period of time, and also test out new ideas quickly. We knew that some of the ideas would be ditched anyway, so we decided that sacrificing a clear separation of logic and presentation is the right way to go.

As opposed to unobtrusive JavaScript, where you add JavaScript as an additional, separate layer on top of your HTML, we found that using Angular-although it "pollutes" your code with UI logic and template directives-is a much more efficient way to quickly build out prototypes and test new ideas.

It has a great community and resources

The popularity of Angular has created a big community around it. As a result, many developers are picking up the framework and decide to make it their major focus so that they can worry less about where their next project is coming from.

Have a look at the following graph, which shows how much angular.js has taken off on the job market recently.

For you as a startup, that means you'll probably have a higher chance of finding an Angular specialist for your team than for any other JavaScript framework.

Another aspect is the availability of learning resources: Treehouse and CodeSchool provide excellent beginner courses for Angular Stack Overflow has more than 70,000 questions tagged with angularjs, and there are tutorials to help you get up to speed with Angular in a single day:

Dedicated angular conferences are now held every year, with videos from most of the top contributors available on YouTube. Check out ng-conf 2014 in Salt Lake City and ng-europe 2014 in Paris.

Angular = the swiss-army knife?

While Angular solves a lot of our problems, it doesn't mean that it solves all of yours as well, and it's certainly not the best fit for every project.

Actually, there's an interesting conversation going on in the community where people discuss the various Angular performance and rendering issues.

For many, it seems we are sacrificing the performance of an application for a faster development workflow. This may be out of the question for companies that develop for huge audiences. That's why Google's flagship app-Gmail- is not based on Angular.

In our case though, given the type of clients we most often work with, being able to prototype and test out new ideas is a higher priority than building extremely scalable, highly-performant application infrastructures. In the end, our clients are startups with a limited amount of time and money, and we're talking about their medium-term goals, not the ones 2 years into the future.

That's why we need to balance: a) spending our time squeezing every single byte out of an application and b) delivering results quickly and efficiently. For the latter, Angular does a brilliant job.

What is one of the best ways your business can leverage the modern consumer? If your answer was anything but "a mobile app" you probably need to upgrade your mindset. As of Q2 2020, mobile users account for over half of the global online traffic . The current figure stands at 51.53%. Although that's down from the all-time high of 52.99% (registered in Q3 2017), it's still a significant enough number to warrant your business adding mobile web apps to your current offerings.

That's not to say you should go 100% mobile. You certainly don't want to leave out desktop users. But ignoring the driving force for the majority of online traffic is a big mistake. So if you're serious about growing your company, you need to add mobile into the mix.

But what does that mean exactly? It means you should be developing for all platforms.

Hold up. Wouldn't that not only take a lot of time but use up a good amount of your IT and development budget? It would if you had to approach every platform independently. If you had to hire teams for desktop, server, and mobile application development, your budget would take a hit. So too would your bottom line. Why? Because developing independently for each platform would take time. While your teams were toiling away (separate from one another), other companies were deploying with agility and efficiency you simply couldn't match.

What do you do? How do you overcome such a hurdle? You use a tool like Angular.

What Is Angular?

Simply put, Angular is a framework for mobile and desktop development. Angular focuses on speed and performance and is used by companies like Microsoft, Autodesk, McDonald's, UPS, AT&T, Apple, Adobe, YouTube, Paypal, Nike, Google, and AWS - and that's just to name a few! That's some serious company to be in. And Angular offers serious benefits.

With Angular you gain:

But again, we ask, "What is Angular?"

Angular is one of the most popular JavaScript frameworks. Built by Google, Angular is open source and allows developers to build single-page web apps and animated menus for standard HTML web pages.

Angular was originally released in 2012 and is still in active development. Angular uses the Model-View-Controller (MVC) architecture, which consists of:

Model - the component which receives input from the controller and manages information. Think of this as the Framework.

View - the component that represents the information received. Think of this as the HTML code.

Controller - the component that responds to various inputs and sends information from the input to the Model. Think of this as JavaScript.

Benefits of Angular

Besides giving developers an outstanding framework with which to build their single-page applications, Angular offers a few very important benefits:

Two-way data binding - Angular binds JavaScript and HTML together. This ensures that changes in the application state are automatically reflected in the view and changes in the view are automatically reflected in the application state.

Directives - are markers on a DOM element that instruct the AngularJS HTML compiler to attach a specified behavior to that particular element, or to transform the DOM element and its children.

Code Structure - thanks to Templates, your developers can produce applications quickly and with surprisingly clean code.

Compatibility - with Angular your applications will almost certainly run on both mobile and desktop platforms.

Each of these benefits is invaluable to web app developers. And because they'll enable your developers to create cross-platform, clean, and efficient applications, they'll save your company money and time.

But that's not all.

Angular was built with Typescript, which is an open-source programming language, created and maintained by Microsoft, that borrows heavily from JavaScript while adding optional static typing. For those that don't know, static typed programming languages are those where variables don't have to be defined before they are used. This allows for the quick and reliable detection of programming errors, thereby reducing the time you need to spend debugging.

Consider how much time your developers spend debugging their applications. Most developers have to budget a good amount of their time doing it. According to Corallogix , developers can spend up to 75% of their time debugging. So any opportunity you can get to save those developers' time is a win.

Yet again, Angular finds another way to save your company time and money.

Because Angular is a framework, it makes it possible for your developers to reuse their code. Imagine your software engineers have developed a perfect set of elements used in your current mobile application. You might want to reuse those elements for the web or desktop applications or even the next iteration of the mobile app. With Angular, reusing that code is really easy.

With such consistency and reusability, your app's time-to-market is reduced drastically and your developer's productivity will skyrocket.

The reusability of clean code and the use of Typescript translates into an app that's also much easier to maintain. Not only are your developers repurposing code that is clean and well written, but it's also bug-free. And when you upgrade a version of Angular, all related packages are updated as well. That (generally) equates to nothing breaking when you migrate from one version of the framework to another.

Conclusion

If you're looking to inject a new language into your development pipeline, and you're hoping to use that language for cross-platform purposes, your business should seriously consider Angular. And if you're unsure if your current developers are up for the task, get in touch with . We'll put together a team ready to help you take your mobile and web app game to the next level.
