All the released versions are backward compatible and can be updated easily to the newer version. By allowing lazy loading technique of AngularJS apps using $route APIs, you can make the transition from older Angular apps to new Angular. An updated “template-var-assignment” feature will review the template files and notify you if any template variable is not assigned a value. It will speed up the front-end development process, as you need not check all variables in the template files. Lastly, most people familiar with Angular know that loading lazy routes required using a custom string in the previous versions of Angular.
The loading speed of modern browsers will get a boost and Time to Interactive will turn quicker. It is amazing how on modern browsers, differential loading can save up to 7-20% in bundle size on an average. AngularJs had a focus on controllers but, version 2 has changed focus on components. It supports features for speed in rendering, updating pages and building cross-platform native mobile apps for Google Android and iOS. And these will form a considerable part of the overall building process.
With Angular 8, the applications generated via Angular CLI come with separate bundles and thereby allows the browser to choose between the legacy and modern bundles (ES 2015+). It helps to ensure that the browser loads the right set of bundles which in turn improves the TTI and loading speed taken by the modern browser. Angular 8 has been out a few months now, and includes a handful of useful new features developers are already putting to good use. Google’s popular client-side web framework continues to evolve, and the latest major release includes features that focus on performance, stability and tooling.
New syntax for lazy loading modules
At runtime, the browser uses attributes on the script tag to load the right bundle. Our Angular developers are confident that IVY will have a huge impact on its Angular 8.0 version. According to the team at Angular, there isn’t a fixed schedule for its release. However, they are planning to release its latest version somewhere in the month of May.
- Lazy-loaded routes now use the standard dynamic import syntax instead of a custom string.
- With the addition of hash-based feature insetUpLocationSync, you will be able to pass an option tosetUpLocationSync.
- AngularJS based on Model View Controller architecture and automatically handles JavaScript code suitable for each browser.
- Also, you have new Workspace APIs that allows you to work with the workspace that is defined in the angular.json, a task which has to be manually opened and modified in the earlier versions.
Angular’s Lazy Loading feature is conceptualized according to Angular Routing, one of the basic Angular.js development services. It’s a vital tool that helps in reducing the size of large files by loading Javascript components asynchronously while activating a particular route. Earlier, Angular accepted the figures in the @loadchildren string even when there was a mistake in loading code or module until its built. Ivy has remained a crucial part of Angular since its inception, and the 8th version introduces it as an opt-in preview.
The typescript 3.7 was introduced in November 2019, and it gave a key hit to the angular 9. The platform is upgraded to work with the Nullish coalescing and elective chaining feature of the in-hand Typescript Who’s Using Amazon Web Services 3.7. This feature assists in remaining in sync with the given environment. Angular language service extension comprises valuable extensions for building up the development practice with Angular.

You have to use the version 12 of Node.js or later for the upgradation. You can run the $ node-vcommand to check which version of Node you’re currently using. It will achieve all this without changing anything in the existing application. The team for Angular is currently testing the IVY changes on more than 600 applications of Google. And the credit goes to the Bazel, which developed and used by Google.
And the final product shows that the developers at Google really did their best. The new version includes a new framework compiler system called Ivy. As the name suggests, this Angular 8 feature allows you to share telemetry about your angular CLI usage. This will allow the Angular team to anonymously collect your usage data like the build speed and commands used. It will also help the team to make Angular even better for the developers.
The top 5 new features of Angular 8
Essentially, when you build the code for production, two different bundles are created instead of just one. One of them will support ES2015+ and then there will be another bundle that will provide support for the older browsers that still only run the ES5 version of JavaScript. This will be particularly useful to web developers who rely heavily on the MEAN stack and make their lives a lot easier.
Though it looks futile, this can be helpful in the long term when there are actual requirements of clean JS codes. Selector – Fewer directives were enabled in the older versioning; however, they were missing in the Ivy preview in the present Angular 8 version. In a demo, a Hello world app was put to test via a webpagetest.org to simulate the slow connection of a 3G network in a device. IVY is an initiative which is meant to build a next-generation rendering pipeline for Angular 8.0. IVY has been hot favorite topic for discussion among the developers. There is a high possibility to gain cache and remote builds on build farm.
AngularJS API Migration Improvements with $location service
These components will ultimately help in boosting the speed of app loading and time to interact . Differential loading consists of bundles that are specially optimized to adapt themselves according to modern browsers. Apart from that, older browsers also get support from the legacy bundles introduced in this feature.
In other words, the version numbers denote the level of changes that are introduced by the release. Thanks to the new framework compiler system, an Angular application can have a smaller build and improved efficiency. The next Angular 8 feature worth mentioning in a new syntax for so-called lazy loading modules.
Based on Your Role
Angular 8 formally added support to Firebase, and currently deploying an Angular application to Firebase is simple, and it doesn’t consume much of the time utilizing Angular CLI, Service Worker. This will be path-breaking as it will A Complete Learning Path to Becoming a Backend Developer 2022 Updated Boot dev unlock many doors for the developers all around the world. To understand the difference in a better way, let’s have a look at the below snippet which compares the codes on the current version of the Angular to that of the Ivy.
Bazel is a build tool that can work in almost all the language input. This will assist you in processes like building and deployment by using third-party tools and libraries. Web workers are essential for improving the parallelizability and the speed of your application. How to Find Developers With this, Angular 8.0 will start collecting anonymous data like commands used and the build speed but only if you allow them to. The community of developers using Angular are always waiting for all the periodic updates that Angular comes up with.
Once Ivy Engine is stable and ready to replace the old engine, it’ll give us some really cool features in the future. 🙁 It’s time-consuming because every bundle needs to be generated twice. Doing so, your build will take approximately twice more time than normally. The latest Angular version – Angular 10 – is now what everyone in the community is talking about. Do you know the extent to which they can help you in your everyday development work?
