I've been using Angular 2 for a medium sized application that will be going into production within the next few weeks. I'm not affiliated with the Angular team at all. I started using it when this app was very much a POC last summer, just as the Angular team was finishing up the 2.0 release. I learned firsthand last summer the issues with using a framework that was still in the oven: constant updates and some depende…

I don't particularly like TypeScript. It slows me down because of several reasons: - Compile time means that it takes more time to debug anything. - The rigid interfaces mean that I need to spend more time researching how to use various modules/libraries (maybe code completion would offset this problem but this is only possible with a heavy IDE that has intellisense or similar - Not Atom). - When I want to test somet…

VS Code (equivalent to Atom in power and scope) has the best intellisense for typescript. I use it over full-fledged IDEs (Intellij IDEA) all the time.

It's interesting how OP says people are moving towards more functional-style Javascript, but also dismisses statically typed Javascript. The two work really well together.

I'm convinced functional style is a fad and nothing will change my mind. The style has been around for forever and there's a good reason most languages are still OOP. We're in the phase of the hype loop where everyone assumes language designers from 15 years ago are idiots. In another few years everyone will be talking about the revival of OOP

I can understand if people think it's a fad, but I would expect people who _do_ like it to also like TypeScript :)

That said, if someone thinks language designers from the past are idiots, then they also shouldn't like functional programming, as it's at least as old.

VueJS is the only of these JavaScript UI Libraries/Frameworks I can stand... The only one whose syntax doesn't make my eyes bleed!... I can't wait for Alibaba's Weex to be officially released so Vue can be used for developing mobile apps too. Reusing components across platforms and the web is the only reason why I would like to jump into the JS wagon!

Any word on when Weex will be released?

I've messed around with Quasar Framework[0], which lets you build mobile apps in Vue (Electron too). Seems like its inspired by Ionic. Still in dev, but I liked what I saw.

Honest question, How does Angular make my life easier or better in some way? I currently use Python and Pyramid as a framework. Mako templates. And SQLAlchemy for database interactions. How is any of this really better?

Angular is different. It is not concerned with the server side at all. It's just about so-called Single Page Applications. This SPA would typically talk to services via "AJAX" (though probably with JSON). These services could be implemented using any technology.

This still doesn't describe how Angular is objectively "better." In fact, because it requires Javascript just to render HTML, it is objectively worse than straight up HTML delivered from a server-side solution.

Hmm. I see that Angular is getting aaaaalot of hate here. I really tried to understand why but have not found really valid reasons, just preferences. I have used Angular 1.x a lot and have just tried Angular 2. It really enables me (somebody who comes from primarily strong backend dev experience) to work on frontend SPA apps productively and fast. It does not 'feel' heavyweight or that it gets in my way too much, but…

Try Vue.js. It's what Angular 2 could have been, if they had taken proper advantage of ES2015 and virtual DOM. Another way of looking at it: Angular 1 and React had a baby, and they named it Vue.js. Vue has HTML templates like Angular and virtual DOM like React. It is faster than both of them. It has a smaller file size than both of them. It has a clever single file component concept that makes developing components…

i've built large applications in both Vue and Angular 2 and i still prefer Angular. don't get me wrong, Vue 2 is really nice, but i strongly prefer TypeScript over any JavaScript revision. Flow is helpful, and Vue 2 has typings, but it isn't quite as powerful as working with a TypeScript framework building a TypeScript app.

to each their own, of course.

I'll be that guy. I'm sure the Angular team are great people, and they're clearly talented devs... but stay away from Angular. It doesn't help with the problems you will actually face. Typed Javascript is a cargo cult. Angular just plain confusing for no apparent benefit. Dependency injection is bizarre. The distinction between modules, components, and directive is unnecessary. The Javascript community in general is…

React is a framework. You can call it a library as much as you like, but that doesn't make it a fact. It comes down to this: What is the relationship between your code and the 3rd party code? Are you calling it, or is it calling you? If most of the code you write is extending some 3rd party code, e.g. React.Component, and most of the time your code is being executed by the 3rd party code, e.g. as render() calls, then…

Having toyed with React and Angular for similar amounts of time (~3 weeks of each), I found React whole lot simpler and more understandable. Probably because it only covers the V in MVC. There is so much stuff in Angular that seems like it belongs in the back end and is just duplicated unnecessary on the front end. (It's not like you are likely to write an application in Angular without a server based back end are you?).

"Angular 1" is now known as Angular.js and is effectively at the end of its line. Angular 2+ is now simply Angular. All new releases follow a naming of version X.Y.Z where X indicates breaking changes, Y non-breaking new features, and Z is bug fixes. Version 3 is being skipped over due to poor naming of the related Angular Router lib. http://angularjs.blogspot.com/2016/12/ok-let-me-explain-its-...

I thought upgrading from 2.x.x to 4.x.x shold break something according to SemVer. So why "it's backwards compatible with 2.x.x"?

I think the distinction is that a breaking API change breaks some of your code, a backward incompatible change breaks your entire codebase -- i.e., fix a few method signatures vs refactor your entire codebase.

What's been your experience with browser-side debugging? The one thing that scares me about typescript is you end up debugging something you didn't write.

That's why I'd personally prefer Flow for that. It has a more elaborate type system anyway. [1] Moreover, Flow is pure annotation, which can be removed by Babel. And Flow is also backed by a large company (Facebook instead of Microsoft). However, if you do want to generate JS, use a language that elminiates runtime errors almost completely, such as Elm or OCaml (through bucklescript or js-of-ocaml). [1] The following…

Using Angular2 for 10 months now. Can say it has been a pleasure to work with it. Sure there are some problems - but it is open source. Free. Can't be complaining about stuff you get for free ;)

One thing - name of the framework should have been something different. At first we thought it is going to be called Angular2 and later it became just Angular. You can imagine that whole community will have to rename their libraries and etc.

In overall, big thank you from our frontend team for giving us a great framework

By default angular-cli produces source maps in dev mode. These work transparently when viewing source and using breakpoints in Chrome, Firefox, Safari, Opera. Just install @angular/cli create a project and a few components and check it out: https://github.com/angular/angular-cli
