In our previous blog NodeJS vs AngularJS we discussed the important differences between NodeJS and AngularJS. In this blog, we will discuss features that developers can avail by Upgrading to AngularJS 5.
In addition to supporting it officially, Google also keeps updating AngularJS at regular intervals. In November 2017, Google rolled out the 5th major version of AngularJS with a number of new and improved features to make the apps smaller and faster. The developers must upgrade to AngularJS to take advantage of several new features and improvements.
Angular comes with version 1.5 of the Command Line Interface (CLI) which includes a build optimizer tool. The build optimizer tool helps speeds up web applications by removing decorators from runtime code. The developers can even leverage the build optimizer to removing unnecessary or additional components of the applications marking the specific parts as pure.
The version 5 of AngularJS comes with an improved compiler. The compiler enables programmers to accelerate the generation of software builds and rebuilds. The redesigned compiler further used TypeScript under the hood to facilitate ahead of time compilation and incremental builds through specific commands.
Angular 5 allows programmers to remove unnecessary whitespace characters from template code through a new option – preserveWhitespace. The developers can enable preserve whitespace option simply by making changes to the global tsconfig.json file. They can even take advantage of this option to reduce the final bundle size of AngularJS applications significantly.
A New HTTP Client
Angular 4.3 came with a simple, small and powerful HTTP client. The HTTP client improved the process of making web requests significantly. Angular 5 comes with an updated version of HTTP client. The updated HTTP client supports parameters objects for both headers and parameters. The developers can take advantage of the improved HTTP client services simply by replacing HttpModule with HttpClientModule in individual modules.
Browser and Server Transfer State Modules
Angular 5 enables developers to share the application state between the client-side and server-side versions of the web applications through the Universal Project. The developers can use BrowserTransferStateModule and ServerTransferStateModule to simplify the server-side rendering of AngularJS applications.
New Router Lifecycle Events
The version 5.0.0 of Angular adds a number of new lifecycle events to the router. The new events enable programmers to track the lifecycle of the router end to end. For instance, the developers can use specific events to visualize the progress each time the route changes by running the events sequentially.
Updated RxJS Library
Angular 5 allows developers to work with RxJS 5.5. Hence, the developers can avail a number of new features and enhancements provided by RxJS 5.5. For instance, they can use lettable operators to eliminate the impact of issues associated with tree shaking and code splitting.
On the whole, the 5th edition of AngularJS comes with an array of new and improved features. The developers can avail these new features by updating their existing applications to AngularJS through a straightforward process. But they must change the format of currency, decimal, date, and percent types.
Likewise, they need to update the dependencies to the latest version of AngularJS and TypeScript. Google further makes it easier for developers to upgrade to AngularJS 5 by providing elaborate update guides for basic, medium, and advanced web applications.
