Let’s figure out what’s what in the Angular world and find grounds for choosing it as a solution for your next project.
First of all, we should mention that Angular is not afraid of big changes. AngularJS was released in 2010, and six years later we meet Angular 2 with a new set of features differing a lot from the original. But apparently, it wasn’t enough as only six months later we again examine the latest Angular version – Angular 4.
This revolutionary process has given rise to much discussion around the framework. It’s time to know what’s so special about it and why developers prefer using Angular 4.
1. Opportunity to Use TypeScript
Beyond this, there are several features of TypeScript that you should know:
- This is an object-oriented programming.
- Has an API which allows manipulating with the DOM (Document Object Model).
- Suits for both client-side and server-side development.
We know about TypeScript thanks to Angular because the whole framework is written in this language starting from Angular 2.
2. Clear Data Flow
One of the Angular 4 advantages is its behavior with the app’s data. There are specific inputs and outputs that every app component has. And these are the places where all data flows happen. In other words, you won’t have to deal with scopes or complex hierarchies.
Moreover, Angular has its own change detection function allowing technicians to check for changes in the most efficient way. Working with Angular, you will probably meet OnPush strategy. If you use it throughout all development process, you will run the change detector only on those components that have actually changed.
3. The Best Animation Engine
The animation engine for Angular web applications mixes two the most famous approaches. On one hand, it has features of Web Animations API – it means that animations can be triggered right from the JS code. But having only this API, developers can do nothing with CSS style sheets.
That’s where the input of CSS Transitions (the second approach) appears. Technicians can work with animation styles using Angular’s component style sheet support.
And even more – in the latest version of Angular, animation function is put into the separate package. It means that if your app doesn’t have animated components, you don’t have to deal with it at all. Earlier, animations were the part of @angular/core module – it means they were included in any application.
4. Universal Rendering
Angular Universal is another beautiful feature Angular 4 has in stock. It makes possible to render your app on a server and gives more opportunities for the project and its users:
- Users get to the content faster.
- When users share the website’s link on Facebook, there is a preview image to make the link more understandable.
As for the near future, Angular Universal will be able to run not only on Node.js platform. It’s a big joy for the enterprises built fully on .Net or Java – deploying Node servers is certainly not that clear for them.
5. Lazy Loading for Large-Sized Apps
The moment always comes when an app is big enough containing a fair amount data. With this moment, slow loading comes processing all of the code and assets – that’s when we need lazy loading.
Lazy loading is one of greatest Angular features letting load only the part of the code – the one the user really needs. For example, if there is a special admin UI on the web page, only some people have an access to it, but it hides a good amount of code behind. It would be great if only these several people could use the code of a special section.
Starting from the second Angular version, lazy loading became easily accessible for all developers.
Making Fast and Beautiful Apps with Angular
Angular releases often surprise us – and these surprises are all pleasant. There is no better platform where you can quickly and easily build one-page applications. Having the unique TypeScript language at hand and understandable data flows, you won’t even notice how much extra work you’re not doing anymore.
