When SHOULD You Use Angular 2?

By Dave Ceddia Comment

People continue to ask – “Should I use Angular 2 for my new project?”

What if the project doesn’t need to be ready for a few months?

What if it’s a small side project, or a proof-of-concept?

Maybe you’ve already been playing around with Angular 2 at home, but you’re stuck with 1.x at work.

At some point, it goes from “should I?” to “why can’t I?” – you want to play with the new toys! Clean component architecture, faster performance, and all the goodies that come with ES6 or TypeScript? Awesome!

How To Decide

Essentially, if this is a low-risk project (failing it won’t mean the failure of your business or something), and you’re prepared to spend some time figuring things out on your own, give Angular 2 a shot.

Just beware that it’s still alpha software, and could change massively, breaking everything you wrote. There won’t be as much help available on Stack Overflow as you’re used to with Angular 1.

To be perfectly clear, I’m not saying Angular 2 is “ready for prime time” here. You still need to weigh the risks and exercise your best judgement. Check out Is Angular 2 Ready? to see the progress toward beta.

Using Angular 2

If you’ve decided to take the plunge, but haven’t played with it at all yet, you’ll want to decide which language to use: ES6, TypeScript, or even plain old ES5.

After that, make sure you’ve got some good tutorials lined up, and dive in.

Using Angular 1

Sticking with Angular 1 for now? No shame.

There are a few things you can do to make your app easier to migrate to Angular 2 if you decide to later on:

  restrict: 'E',
  scope: { ... }, // isolate scope
  controller: 'NameCtrl',
  controllerAs: 'name',
  bindToController: true,
  // no link
  // no compile

Learning React can be a struggle -- so many libraries and tools!
My advice? Ignore all of them :)
For a step-by-step approach, read my book Pure React.

Loved it! Very well written and put together. Love that you focused only on React. Wish I had stumbled onto your book first before I messed around with all those scary "boilerplate" projects.
