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…

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 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 something quickly, I often get annoying compile-time errors along the lines of 'code is unreachable...' among others.

- It requires more planning to do anything (since you have to design the interfaces before you can start to implement). This is also not good if you just want to try something quickly and then roll back later.

- Changes to one class/interface tend to have a large cascading effect on other classes/interfaces so it takes more time to make changes to code - This happens with JS too but to a much lesser extent.

- Adds lots of unnecessary dependencies to my project.

- Complicates setup and DevOps tasks, Dockerizing, (E.g. due to version mismatches and thousands of other potential issues) etc...

The reason why I don't like heavy IDEs is because:

- They're slow and clunky (sometimes they freeze for a long time in order to index content)

- The use up a ton of memory.

- They make your team lazy when it comes to structuring your source code into proper folders (since you start to rely more on search features of the IDE to find things).

- They take ages to install.

- Support fewer operating systems.

- Are usually proprietary and difficult to customize.

- More prone to bugs.

I loved working with angular. They lost us when they released angular 2. It was complete breaking changes and the upgrade path was a nightmare. They basically were forcing users to completely rewrite their front-end if they wanted to upgrade. So the team figured if we have to rewrite our front-end, what's keeping us on angular and why would we stick with a framework that doesn't seem to have any issues forcing it's users to do complete rewrites just to use the newest version?

I have built multi-10k+ line applications in angular 1, 2 and react. My personal preference is react by a mile.

The concept of modules and dependency injection was nice before we had any sort of module systems, but at this point it's essentially entirely busy work, given tools like proxyquire when testing.

Template compilation errors are a nice step up from 1, but those that I've seen have been very misleading and have been the cause of wasted hours debugging.

Angular 2 makes extensive use of the Reflection API for metadata, which combined with the fact that angular-cli is hard-coded to perform static analysis (even if you disable AOT) is another pain point. I'm trying to build the equivalent to "react storybook" for our platform, and it's taken me about 3x the time it would have with React.

With all of that said, if you need a "think-inside-the-box" tool for a large, decentralized dev team, angular can win out- there are fewer places to look for documentation, which will be nice when angulars documentation improves.

I actually find that React better encourages smaller, cleaner components with fewer responsibilities, but that's also likely due to being very familiar with the redux paradigm.

Finally, if you want very flexible components, react wins hands down, because components can be used as properties to other components; dynamically rendering components in angular has always had an inversion of control issue.

That's been my experience; ymmv.

I agree with this, few months ago I was trying to learn AJAX, I tried Angular (because it is backed by Google), few weeks into reading more about it, I was still reading the docs. Then, I read that VueJS was a somewhat better and lean version of React, so I skipped React and started with Vue, I was surprised that I wrote the complete app within a week of starting to learn Vue ( https://github.com/thewhitetulip/Tasks-…

I really don't want to sound like an ass, but if you were at the stage of 'learning AJAX' a couple of months ago you are probably not in a position to judge the merits of JS frameworks like React, Vue or Angular.

I agree 100%. TypeScript is an invaluable, mature technology that provides large productivity boosts to any team that maintains a mid-sized code base. It plays extremely well with React too, and it's benefits are independent of the tech stack. If you are used to typed components/templates, you will NEVER want to go back. I would argue that is more important to have static typing in the front-end compared to the back-…

In 2014 I used Typescript on a four month long project. I liked it alot compared to using just JS, however compiling was slow. I retried using Typescript 1 month ago. Compiling took 6-7 seconds for about 8 files. I could not find a solution and gave up using TS. I hope that's just me doing not good enough research.

Must be something with your setup, tsc is known to be quite fast. Maybe try using it with the watcher? "tsc -w" and you'll never need to compile more than one file at a time.

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 much easier. It uses a one-way data flow concept like React+Flux. Vue even has it's own competitor to redux/mobX called Vuex, and what makes it easier is that Vue is cognizant of Vuex's existence. There are really solid dev tools for Chrome as well (Vue and Vuex are aware of the dev tools as well).

I run a dev meetup, and I had planned to give a talk there on Angular 2. I even gave talks on JS tooling a year ago and TS last summer in preparation. Instead, I gave a talk on Vue this month, and people loved it. Here are the slides if you want to check it out (there are even embedded Vue apps!): https://azurelogic.github.io/vue-js-2.x-talk/#/

"It requires more planning to do anything. This is also not good if you just want to try something quickly and then roll back later."

Since you can pretty much type javascript in to a TS file and it will work I don't see this being valid.

Also planning is good, if your not thinking about the structure of your code (which does not take that long) then your just producing diarrhea.

Thanks to this comment I'm looking at it now. The only thing I hate is 'v-for="todo in todos"' as an html attribute. I would personally prefer a mustache-like syntax.

Other than that, this looks awesome. Time to develop a todo app.
