7 Must-Know Reasons Why You Should Switch To

Angular 4 From Angular 2

Recently, I’ve shared a blog called “AngularJS Gets a Button! Angular 4.0.0 is Now Available” and it helped a lot to many of our readers to gain the knowledge out of it. Well! Done with the glimpse, I am here with the new blog to discuss about the key reasons to choose Angular 4 as it has a gentle learning curve.

In the comparison of Angular 2, there are lots of new things added to the list. I am not talking about the new features, but pointing at some tweaks as they are here to enhance the old features. Hence, let’s have a look together that what this new version has to offer and then discuss about switching.

A bit of introduction Change is inevitable and things are constantly changing with the programming too. At first, it seems doubting to try to keep up with the new updates. However, in case of Angular fortunately the development team has done us a favor with what they are referring “invisible-makeover”.

It’s actually an easy upgrade that has inspired me to write this post and currently my organization, Bacancy Technology is working on three projects that are using Angular 2 and all of three has given us a flag to upgrade to Angular 4 and without any complications at ease we are successfully doing it.

So let’s get to it.

Why not version 3 then?

Actually the Angular libraries live in the single GitHub repository and each of them are versioned the similar way,however they are distributed as different NPM packages.Owning to the misalignment of the router package’s version, the Angular team made a decision to go Angular v4. As all the core packages are aligned so that will be easier to maintain and avoid any confusion.

At present, Google applications are using the Angular version as equivalent to the master branch of the Angular repository.So, whenever the new code is generated and added to the master, it will be directly integrated into Google’s single, where other products such asAdsense, Maps etc. are being hosted.

As a consequence, all of the projects making use of Angular within at Google will run their widespread test suites against this newer version. This is what makes Angular team very self-confident to cut a new release as it will enclose the same combination of versions of Angular packages that Google is testing currently. This is the reason why Angular 4 makes sense as an aligned version and it also ensures to make it easier over the time that in turn helps the developers to be more productive and only focus on adding viable features.

Reasons to update to Angular 4 1. Angular 4 is smaller than Angular 2 The Angular development team has done a great job minimizing the ahead of time generated good. The changes involve the reduce size of the generated code.So the complex the template is the higher the saving is.

2. Angular 4 is faster than Angular 2 The speed enhancement is really an appreciating job. You can experience it at the time doing development.

3. Angular 4 has enhanced *ngFor and *ngIf So from now onwards if/else style sytax to *ngIf.When you are creating asynchronous calls to a Firebase database, you can include a loading screen within the page whenever the data loads. There is an actual potential within the ability of an if/else.

4. Angular 4 Source Maps for Templates So many times in programming there are not so helpful error messages, however; in the case of Angular 4 it continues to try by generating source maps. When an error is occurred in one of your templates, Angular 4 “generate source maps to provide a meaningful context in terms of the original template.�

5. Animation Package It lets you find documentation more easily and lets you leverage the better advantage of auto-completion. You can add animations yourself to your main Ng Module by importing Browser Animations Module from @angular/platform-browser/animations.

6. Angular Universal Universal is the project that lets the programmers run Angular on a server and which is now up to date with Angular again. This is the first release since a community-driven project is adopted by the Angular team. This release now includes the results of the internal and external work from the Universal team over the last few months.

7. TypeScript, 2.1 and 2.2 Compatibility The Angular team has updated to a more recent version of TypeScript.It will increase the speed of ngc and you will get the improved type checking throughout your app.

Wrapping Up Almost all of the Angular 2 application will perform perfectly fine using Angular 4 without changing anything. It’s not a monumental upgrade, I mean in terms of apparent changes, however;it offers a huge enhancements to Angular 2. I am so much happy with Angular 4 becauseAngular development team has fulfilled the commitment for the smaller and faster Angular applications!
