Angular use cases

-

Angular is an open source framework mainly used to build efficient and sophisticated single page applications or is used for cms headless applications. Angular is based on TypeScript, developed and maintained by Google.

Why Angular?

What are the greatest benefits developers can get by using Angular in their projects? The strong sides of Angular include:

- Detailed documentation. Angular offers detailed documentation where developers can find all the information they need. As a result, developers can quickly develop technical solutions and solve any problems that arise.

- Support by Google. Many developers believe that Google support is another advantage of Angular, making the platform trustworthy. Additionally, all major releases are supported for 18 months, 6 months of active support during which scheduled updates and patches are released regularly, 12 months of Long Term Support (LTS) during which only critical patches and security patches are released.

- Great ecosystem of third-party components. The popularity of Angular has resulted in the emergence of thousands of additional tools and components that can be used in Angular applications. As a result, you can get additional improvement interms of functionality and productivity.

- Component-based architecture from Angular 2. Angular moved from MVC to a component-based architecture. According to this architecture, the application is divided into independent logical and functional components. These components are easy to replace and detach, and can also be reused in other parts of the application. In addition, the independence of the components makes it easier to test the web application and ensures that each component runs smoothly.

- Ahead-of-time compiler. Angular's AOT compiler converts TypeScript and HTML to JavaScript during the build process. This means the code is compiled before the browser loads your web app, making it render much faster. The AOT compiler is also much more secure than the just-in-time (JIT).

- CLI. This is probably the most liked feature of most Angular developers. It automates the entire application development process, facilitating application initiation, configuration and development. The Angular CLI allows you to create a new Angular project, add functionality to it, and run unit and end-to-end tests with a few simple commands. It not only increases the quality of your code, but also makes development much easier.

- Angular Elements. Starting in Angular 6, developers can easily add custom elements to any web application built in React, JQuery, Vue, or any other environment.

- Ivy Renderer. This is another great feature that became available in Angular 6. Ivy Renderer translates application components and templates into JavaScript code that can be displayed by a browser. The main feature of this tool is the tree-shaking technique. During rendering, Ivy removes unused code to make it cleaner and smaller. As a result, web applications load faster.

- Angular Material. This collection of Angular optimized Material Design elements allows developers to easily integrate UI components.

- Dependency injection is Angular's disputed advantage. In plain language, dependency injection refers to one object that provides the dependencies of another object. These dependencies define how different components are linked and show how changes in one part of the code affect other parts. On the one hand, the use of dependency injection makes the code more readable and easier to maintain. It can significantly reduce the time spent on testing and thus lower the cost of creating websites. Starting in version 2, Angular provides developers with a separate dependency injector tree that can be changed or replaced without havingto reconfigure all components. But on the other hand, dependency injection can be time consuming and creating dependencies for components can be difficult.

- Angular Universal. Used for server-side rendering, Angular Universal brings several benefits to your project. First, it makes it easier for web robots to improve your web application's ranking in search engines. Second, it reduces page loading times and improves performance on mobile devices. These factors help to increase the number of visitors to your site.

Which projects can benefit from Angular?

Enterprise web apps

TypeScript has all the features you need to create large-scale projects. TypeScript comes with auto-complete, advanced refactoring, and navigation features. Moreover, thanks to the architecture of this tool, you can easily reuse and maintain the code.

Apps with dynamic content

As Angular's main goal was to build single-page web applications, it has a wide range of SPA creation tools. Moreover, it is an ideal technology for websites where the content should change dynamically depending on the behavior and preferences of users. Dependency injection ensures that when one component changes, other components associated with it are automatically changed.

Progressive web apps (PWAs)

PWAs were developed by Google in 2015. The Angular team anticipates the upcoming popularity of PWA and is working on streamlining the PWA development process. Angular 5 comes with built-in PWA support. New CLI commands that have appeared in Angular 6 enable developers to easily transform their web applications into progressive web applications.

SEO-optimized websites

Starting with version 6 for a SEO optimized page with help it becomes server side rendering (SSR). During server-side rendering, the Angular app's JavaScript code is already executing on the server and the full HTML structure and content will also be available to crawlers. The technology that enables server-side rendering for Angular applications is called Angular Universal. Angular Universal generates static application pages on the server through a process called server-side rendering.

 

Which projects don’t need Angular?

Sometimes Angular only charges your project. We do not recommend using this tool in the following use cases:

Lightweight websites with static content

Angular is perfect for sites with dynamic content, but insufficient for creating small pages with static content. Implementing Angular in this case only increases the overall size of the project and thus significantly increases the load time. This is the main reason why we don't recommend using Angular for landing pages and sites with static content.

Short-term projects

Angular is not a good option for short-term projects or startups with limited resources.

Apps with a microservice design approach

Angular is not suitable for applications with a microservice architecture in the UI. If you want more flexibility in selecting additional tools, do not choose this tool. Angular is a complete solution - it doesn't give you full control over the size of your application as it lets you choose only the things you really need.

 

There are a few key things to consider when choosing Angular. When you are considering a technology pile, you should carefully study your design.
