What’s new in Angular 8 Version?

Angular 8 is subsequently right here and consists of a preview of Ivy, provider worker help, differential loading, and a few other finishing touches. Manfred Steyer explains the most crucial changes in the most modern Angular launch.

Angular 8 was just released!

As planned, there were no surprises: the replacement of the framework and CLI may be carried out by way of the usage of ng replace and the new functions are a welcome addition consistent with the motto “evolution in preference to revolution”.

Software builders and Angular network had been eagerly waiting for the new release of Angular to occur with quite excessive expectations. The new edition looks promising and is majorly focused on making it simpler for builders to build different types of apps, as properly as enhancing the performance.

Features of Angular eight and improvements

1. Differential Loading by way of default

Angular will now be able to take advantage of differential loading by way of default. This will allow the browsers to pick out the contemporary or traditional JavaScript bundles of the app on the idea of the competencies of the app. What this means that the package of JS can be loaded as a result while the app is used.

This has been made feasible due to the fact the new version will feature separate JS bundles for modern (es2015) and traditional (es5) builds. As a result, the loading time and speed of the app might be faster.

2. An improved guide from code editors

The path configurations in Angular will now use dynamic imports, which will improve the assist from code editors which include Visual Studio Code and WebStorm. These editors can be capable of apprehending and validate the imports automatically.

What Angular team has executed is updated the loadChildren key in the path configuration. Previously, this key becomes custom to Angular, and now it has been moved to enterprise popular dynamic imports.

Angular 8 Release Highlights

I’d say that the range of obvious new functions in Angular 8 is limited, but there are still a few chocolates indeed:

Differential loading

Your Angular eight apps will now be automagically more performant, thanks to differential loading.

With differential loading, two bundles are created when constructing for production: a package for current browsers that assist ES2015+ and a package for older browsers that most effectively help the ES5 version of JavaScript. The accurate package might be loaded automatically by the browser, way to the help of ES6 modules in more recent browsers.

This new function results in the most important single performance development for Angular v8. Newer browsers may be able to load less code and load a much smaller quantity of polyfills.

You don’t need to do something unique to benefit from differential loading, the ng construct command with the --prod flag will take care of bundling the entirety so that differential loading is operating out of the box:

$ ng build --prod

Updating to Angular v8

To update to the state-of-the-art version of Angular, visit update.Angular.Io. Alternately, the builders can use this command for the replace:

ng replace @angular/cli @angular/core

If your app makes use of Angular Material, you’ll want to follow with this command:

$ ng update @angular/material

This command will also take care of changing your Angular Material component imports to each specific component rather than importing from the global @angular/material.
