The Client Perspective
Netflix, PayPal, Gmail, YouTube TV, Udacity are only a few examples of custom product development with the help of Angular. As you can see, this framework is the best option for complex websites with interactive content, and functionality. If you are looking to build eCommerce platforms, weather applications, social media, or video streaming apps – Angular is the right choice for you.
For startup development, there will be a constant dilemma about how to choose the best technology for the app. And while the big brands’ app development may serve as an inspiring example, the best way is to start with an MVP and value the main Angular pros and cons.
- Quick performance with smooth navigation and fast page load time;
- A scalable app with the opportunity of adding new features with no time;
- The app is easy to cover with tests which hugely benefits the quality assurance results;
- Stable web application;
- A lot of functions initially available in the framework which speeds up the development process;
- Native and PWA support – it is possible to use Angular as a native app due to frameworks like Ionic or NativeScript. Plus, there is a chance to develop progressive web applications;
- Great accessibility.
- The rates. Hire an Angular web developer could be quite expensive;
- Difficult in fixing. If the devs initially didn’t follow the best practices of Angular web development, such apps would have a bad architecture which means that fixing such applications would be harder.
The Web Developer Perspective
We’ll focus on the most prominent features and reasons why software engineers fond of building web apps with Angular.
- Dependency Injection. Dependencies describe the code interaction with each other, and usually, every change in dependency requires to change the components as well. Angular allows using injectors that interpret dependency as an external element. This functionality helps to create a very scalable, configurable, and reusable module that can be used in a variety of cases. One of the cases is the creation of your own library for Angular. It is a highly valued feature that you always need in any type of project.
- RxJS usage. While working with Angular you cannot avoid using RxJS (a reactive programming library). And while it can look very unclear from the first sight, RxJS makes the asynchronous flow with multiple events incredibly stable, easy to build, and debug.
- CLI. A highly configurable setup that allows adding tons of features to the Angular.json. CLI contains very useful and timesaving commands to run units, tests and perform updates. As a result, it makes the development process very easy. Production builds of Angular make the codebase really lightweight regardless of the built-in amount of functionality.
- Templates. Angular use very clear templates that have great support for TypeScript checking and IDE helpers.
- Decorators. The approach and syntax in creating components, modules, and decorators lead to the creation of other easy to use libraries with decorators usage.
- Libraries. As Angular has a really great style guide it helps a lot to write a good project. Also, Style guide allows other open-source contributors to improve the code style for their own libraries, useful tools, and packages. Therefore, while creating new libraries, you can extend Angular functionality. This is a useful feature when you need to solve the same issue in different apps. So you’ll save tons of time by addressing previously created libraries.
- Forms. Angular forms have incredible architecture. You can use different approaches (e.g. Reactive Forms) with the same native component. Moreover, you can create your own form element using ControlValueAccessor. The package has all the required functionality to build forms for your needs.
- HttpClient. This is sort of a mechanism for communicating with a remote server over HTTP requests. This feature helps devs to receive external data and work with it. A lot of boilerplate code was removed after HttpClient was released in Angular 4.
- Utils. Pipes, classes, etc. which already exist inside the framework which is great for simple transformations on data.
- Routing. Angular routing supports a lot of different features like lazy loading, redirects, regex routes, or routes parameters. Also, it supports the use of several routers, so you can have a few routing systems each for its own needs.
- Security. Angular has a pretty strict default security system so you can build your app following the best practices being protected online.
- Community. As an open-source project, Angular was build and maintained by the best brains in software engineering. You can find various training materials, tools, and discussion topics on using this framework. Angular’s huge community is the best representation of the framework quality.
To summarise, it is hard to cover the whole list of Angular advantages (among which such great parts as accessibility, animations, testing, code splitting, etc.). Basically, Angular for web development has a very thoughtful architecture due to which devs can build robust and scalable web apps for client’s needs. All together, it makes Angular number one among software development tools.
