Here’s why to Design Responsive Web Apps using Angular JS

Getting started with Angular 5. Hi, are you a beginner in Web… | by Onejohi | Medium

The decision of which tools or tech stack you should use to get optimum value of your investment is nothing but a conundrum. From a business point of view, you couldn’t risk going wrong here since these risks can cash-on in any minute. So, what tools are capable of giving you the most bang for your buck?  – Well, off the top of my head – Angular framework.

Here comes the most expected question – But why?

The fact that there are various reasons for using Angular framework is why it is deemed one of the most recommended for businesses and enterprises.

For one, the current update Angular version 9 fixes all the bugs that created problems in Angular 8. The framework is not just better than most of the frameworks out there, but is a constant improvement on its previous versions as well.

For instance, Angular 9 comes with Ivy as standard renderer. Meaning, developers can ship less code as fewer instructions are required now. This ripples down to other advantages which previous versions were lacking.

So, let’s move on to the reasons validating why one should build Angular applications.

Benefits of using Angular for business

1.  Functionality

When it comes to facilitating the development process, Angular is the one framework developers look up to. It won’t be overstating to say it offers out-of-the-box functionality. Not only it provides tools for routing (in order for you to fetch the data you plan to add into your app), but it’s preconfigured environment also takes care of development and testing.

With Angular, you don’t have to incorporate third-party libraries in your tech-stack for creating basic functionality for your digital product. It all can be done via its official library provided by the team of Angular, assuring you of its security and impeccable quality of code. All this reduces the app development cost and time, an advantage of Angular that businesses investing in mobile app development always look forward to.

2.  Clear code with TypeScript

One of the Angular framework advantages is that it is built with Typescript. But what does this signify for a business?

Well, this means since Typescript is a strongly-typed and the base language for Angular, it allows developers to keep the code clean and neat. And the cleaner the code, the better your app will perform.

This ripples down to making bug-fixing easier. The developers can spot and then eradicate these errors as they are being typed. It’s basically like Grammarly for your code, cool right? Moreover, it also helps in managing and maintaining large codebase (beneficial for enterprise-scale projects).

Moreover, Angular 8 uses Typescript version 3.4 offering type inferring, reduced build time, and syntax changes and has exceptional navigation, autocompletion, and refactoring services.

3. Consistency with reusability

Making Requirements Reusable

Let me put it out there straight – inconsistent coding not only increases the risk of delayed time-to-market but also escalates development cost while reducing the efficiency of the digital product. And that is not something you, as an entrepreneur, would want.

This is where developing mobile & web apps with Angular would play to your benefit. Angular offers consistent code, which has its own benefits such as it makes using websites easier while allowing the use of templates or even predefined snippets of code.

Notably, upon comparing Angular vs React, I found that Angular is more of a fully-responsive web design framework. To enhance consistency,  the team has developed and optimized Angular CLI tools used for making specific repeatable blocks of code from the command line.

4. Productivity

Since the code is consistent, its positives also produce increased productivity. developers no longer have to invest their time in figuring out what utility, function, or a component does because it’s all taken care of by Angular.

Also, the readability of the code makes it all the more easy for developers to slot into an ongoing app project.

Moreover, Angular organizes codes into buckets (modules). These modules make app functionality organization facile by dividing it into features and reusable chunks while allowing for lazy loading that enables feature loading in the background or on-demand.

This JavaScript framework for building web apps makes it an achievable goal to dissect and segregate the labor across different team members while ensuring organized code, which improves productivity with appropriate modules built.

5.  Maintainability

Why it's important to develop maintainable softwares

Speaking of the benefits of Angular, it addresses the concern of maintainability in two ways – by using Typescript and focusing on testability.

Almost all established mobile app development companies use Typescript that allows developers to find bugs as they type the code. Moreover, TypeScript also enables developers who are unfamiliar with the codebase to quickly get acquainted with it since they can see the types of data moving through the application.

As for the testability front, dependency injection is a crucial aspect of Angular which contributes to making test writing easier. In fact, the framework also includes support Protractor for end-to-end testing.

Additionally, when upgrading current Angular to its latest version, all packages related to it are also updated at the same time. This signifies that HTTP, Routing, and Angular Material are also included. And updating can also be done by one single command “ng update” and it would do the trick without wasting any time.

6.  Angular material

One of the Angular framework advantages is Angular material. In brief, Angular Material is a set of UI modules and components that are well-tested and hence ready-to-use. It follows Material Design principles by Google and possesses a wide range of UI components like navigation patterns, buttons, indicators, and form controls. The components here are modified to match better with browsers.

What these modules do is make the design workflow easy, which as a result, enables developers to add new elements and create digital products in an expedited manner while hindering the app performance to a minimum.

7.  Declarative UI

HTML is used here to define the UI of the mobile app. It is believed that HTML is one of the less convoluted, declarative, and intuitive programming languages as compared to JavaScript.

Now, if you are wondering how this helps you as a business, then let me tell you that due to this functionality, developers won’t have to invest unnecessary time in program flows and deciding what should load first. All you have to do is define what you require and Angular can do it.

8.  Simplified MVC architecture

On top of other benefits of Angular, this one really is a gem. This framework is fundamentally embedded with the original Model-View-Controller software architecture setup, though it might not be as per established standards.

Moreover, the Angular framework doesn’t ask developers to dissect the app into separate MVC components and create a code that could combine them. Instead of this, it only needs developers to divide the app and that’s it. In short, it facilitates less coding enabling apps to perform faster.

9.  Easier Unit-testing

Because the components are independent of each other, it makes the unit testing process easier. As for the benefits of Angular, one of them that is highly appreciated is that it supports the development of highly testable websites and applications.

In fact, it is generally believed that this framework was fundamentally designed keeping the ease of testing in mind, something which renders impeccable digital products which is what any business expects from the development.

Type of applications and websites built with Angular

1. Netflix

Netflix 'Shuffle Play' Feature Randomly Streams Selected Titles - Variety

Probably the most hyped and popular streaming entertainment application Netflix is a classic use case of Angular. More specifically, the team at netflix used AngularJS as the frontend tool and while the backend needs were satisfied by Python and Flask.

It is also apparent after what we have read above that the cost of developing an app like Netflix can be minimized with the benefits and attributes that Angular offers.

2. Upwork

A rather insanely popular platform for freelancers Upwork also incorporated the Angular framework for its website and mobile application to render the application impeccable performance.

3. Youtube TV

Youtube TV is Google’s alternative service to Hulu + Live TV. This platform was developed with the help of Angular 2 which launched in the market in 2017.

4. Gmail

Gmail, the mailing service in the form of both mobile apps and websites also employs the goodness of Angular framework. In fact, other products by Google are also developed using Angular, which serves as a reason why many enterprises and mobile app development companies alike trust it with their digital products.

To conclude – Although, contenders like React might have more searches online, the majority of developers show more interest in Angular because of the availability of ready-made solutions. As for the business front, Angular definitely outshines React on the grounds of development speed and productivity – an attribute that is a ‘deal-sealer’ for enterprises, isn’t it?

Developing App? Here’s Angular Practices & Tips

Angular has been the most famous javascript framework among the developer community. It’s an MVC framework which provides pre-built components for developing the software application.Angular(2+) is based on Typescript , which is a superset of JavaScript. It comes with its most important advantage of static type checking that provides compile-time checking for any variable declarations and definitions.This blog is based around some best practices for Angular which I figured out while developing applications. There are also some bonus tips which I believe would help you with Angular development.

Follow the component based approach

Angular comes with the component-based paradigm which is also one of its best practices. It helps in maintaining modular and readable code.

While developing an angular code, if you think that something can be used multiple times as an independent piece of code, make it a component. A very basic example can be a simple dropdown which shows a list of options. The drop-down can act as an independent component with its own methods and template.

Few more examples could be – breadcrumbs for navigating throughout our web application, a simple alert box showing error/success messages or a loader. We tend to ignore these while thinking of modular approach but all these above examples can be thought of as independent components which can be reused over and over again.

Avoid using one huge global CSS

Angular’s current structure includes individual folder for every component. This folder includes-

  • .ts file for component logic
  • .html file
  • .css file for the component

So, keeping all of your CSS in one common CSS file would not only make your code less readable, it would make it less maintainable.

The best approach to style your components is to separate the global CSS with the local CSS (here local CSS refers to the component CSS). You should write your CSS in global CSS only when the CSS is written for the entire application and then if you need to style your component specific to a certain page, you can surely write in the local CSS.

Use CSS preprocessors for faster development

We can also use CSS preprocessors like SCSS/SASS for our Angular projects and I prefer them instead of writing plain CSS as they provide a lot of advantages over writing plain CSS. To mention one, the use of partials so that you can also separate your styles into multiple files for maintainability. If you guys want to know about partials, I would suggest you to go through this link.

You can divide your styling into multiple SCSS files just as we divide our application into multiple components. SCSS/SASS helps in writing smaller code which would ultimately get converted into CSS. So, why not save time and use it to our advantage.

Save your time by using build tools

Tools like angular-cli have come up as a lifesaver for angular developers. It’s basically a boilerplate for an Angular application which helps in quickly setting up the angular application for your new project. It comes with all dependencies required for building your application and also has an inbuilt webpack which helps in bundling all your code and assets. Angular CLI helps to increase developers productivity through scaffolding by creating a component file, template file, stylesheet file etc. It comes with few basic commands which help in faster development like:-

  • ng g component my-new-component – it will create a new component with the name my-new-component.
  • ng g service my-new-service – it will create a new service with the name my-new-service.
  • ng g module my-module  – it will create a new module. A module is basically a collection of components which help to serve or attain a particular functionality.

Use ES6 paradigm and approach

Interfaces in Vanilla ES6 JavaScript – Full-Stack Feed

Though right now ES-8 is the current drafted version for ECMAScript but ES-6 came up with its own new features that are still widely used by developer community as they produce the same results with fewer lines of code and for best practices, every developer should know how to use them.

  • Arrow Function – In javascript, we use this keyword to refer to the current execution context. Previously, when we had to write javascript functions, this keyword would refer to the function context and we had to use a temporary variable to store the current execution context, so that we never lose it but with the arrow functions, the current execution context is never lost. For e.g., we could use an arrow function like this;

// ES5

var sum = function(x, y) { return x + y };

// ES6 (arrow function)

var sum = (x, y) => { return x + y };

Now, see the ES6 arrow function is just so compact and easy to understand and we can easily use this keyword inside this function to refer to the current execution context.

  • Template Literals – Template literals have come up with how we deal with printing strings having dynamic content.

For example, without template literals if we had to print a hello and goodbye message to a person, we would write something like :

const name = ‘AMAL’

console.log(‘Hello ’ + name +’ !’);

console.log(‘Goodbye ‘ + name + ‘ !’);

Now using template literals, it would be something like this:

const name = ‘AMAL’

console.log(`Hello ${name} !`);

console.log(`Goodbye  ${name} !`);

Now, who wouldn’t like to use the second syntax as it’s really easy to use and we don’t have to care about putting the spaces at right places so that the formatted output is correct.

Apart from these, const and let keywords came up as a replacement for global var variable so as to enable effective scoping of variables.

For a detailed overview of ES6 features, I would recommend having a glance over this.

Use Lazy Loading wherever possible

What is Lazy Loading | Lazy vs. Eager Loading | Imperva

Lazy loading is based around loading modules only when you want them to show.

We know about Angular’s modular architecture where a code is divided into modules with each module having its own components.

These components are basically views which might have some dynamic data. These components are rendered with the help of angular routing.

Lazy loading is one of the best things that angular framework comes with.

It’s based around one principle – ‘load/use it when you need it’. Oh, yeah what a lame
explanation I’ve given. There is a routing.ts file in every module which defines a URL for rendering each and every component.

Now when it comes to implementing lazy loading technique, what we do is we define a routing file for each and every module and we import each module only when the URL changes and it corresponds to rendering a component defined in the routing file of that module.

This technique requires a bit of patience to learn but take my words, it’s worth implementing. I can tell you with my personal experience; we reduced the loading time of our website by 3-5 seconds by implementing lazy loading.

Previously, we imported the whole bundle each and every time the user hit our website URL making our site slow while rendering. Then after implementing lazy loading, we only imported the module containing component required to render our index page and we just loaded other modules only based on what URL the user is switching to.

The Angular docs surely cover the lazy loading technique and it’s worth reading. You can check this link to learn more about it.

Follow DRY principle, extensively use services and directives


DRY – This keyword is very famous in the developer community and it just stands for Don’t Repeat Yourself. So, when writing any code- be it Angular or any language- if you feel that you are basically writing or repeating the same code in every component, then you must pause then and there and rethink whether the code can be placed at a suitable place and can be shared by every component.

For example, if you want to call an API that updates user data, don’t call it in every component. What I would do it, I would rather make a service for it in the .service.ts file and would call that function whenever I need any component.

Also, it serves the purpose of using services in angular. Services help us in saving and fetching data and also help us write common functions which could be used by multiple components.


Now switching over to directives. A directive is a piece of code which is used to perform a specific task. Directives are of 3 types in Angular – component, structure, attribute.

  • Components are as we all know templates with logic to handle data.
  • Structure directives modify DOM by adding or removing an element.
  • Attribute directives change appearance or behavior of an element.

Once, I was wondering to restrict input elements to accept only numbers when a user types in for a phone number field which shouldn’t accept alphabets. For this, I built an only number directive which would only allow input elements to accept numbers through the keycode. So just by using this directive as an attribute on an HTML input element, I can modify/change its behavior.


Following best practice is never a compulsion. There are many ways of doing things and you may choose any path. However, using best practices mean that you are following a method or a technique which is tried and tested through experiments and has proved to be effective to attain desired results.
