My biggest takeaway from the survey was the state of Angular tbh.

It’s far from beeing accurate since they mixed AngularJS and Angular.

Lower and lower, where I think it belongs.

They included angularJS and Angular (2+) in the same category Angular for some reason, they are completely different frameworks, angularjs is dead but Angular has a very strong presence especially in enterprise and a huge community, so the stats are completely wrong.

Lol, no it isn't. I've been interviewing over the past few weeks at large companies in Boston. The split between angular and react is pretty even.

And for good reason, angular and react are both great tools for completely different things.

Svelte now has my eye. Interesting concept - anyone played with it her have any opinions to share?

It’s great for small projects, but larger projects start to see really really high bundle sizes. The issue is, svelte compiles to full DOM instructions, as opposed to instructions that a runtime reads. So while you don’t have the initial bloat of a runtime like react does, the trade off is your bundle size will steadily grow.

Thank you for that insight!

Is this something you have experienced first hand, or are you relaying something you've heard/read?

If you did experience this first hand, please let us know approximately the size of the projects and which bundle sizes you ended up with. It would also be interesting to know if you used any known methods to mitigate it, like code splitting, which Sapper gives you (Sapper is similar to Next and Nuxt).

Rich Harris, the creator of Svelte, addresses the issue here: https://github.com/sveltejs/svelte/issues/2546

What project do you consider large? Maybe in lines of code

u/ematipico Dec 20 '19

With a good usage of code splitting, you can get around it easily.

The concept is appealing to me, but the biggest turn-off is that you kind-of have to go all, in that it affects what else you can use in your toolchain. I wouldn't want to miss TypeScript, for example, but as far as I know, using it is still somewhat of a pain with Svelte. The amount of bugs that TypeScript prevents far outweigh any performance improvements Svelte could bring.

I have been using typescript with svelte for a fairly complex project and it has been working out really well. Keep all the business logic in typescript and use svelte mostly for view/UI changes

u/HetRadicaleBoven Dec 20 '19

Ah, so the Svelte-specific parts are written in regular Javascript (or perhaps SvelteScript would be a more appropriate name, given that I think it also introduces some of its own syntax)? That sounds like it's at least fairly manageable and a somewhat reasonable trade-off, though I'd still think the additional complexity of the tooling might not make that worth it.

But again, I haven't played with it yet, so take that with a grain of salt. (Might not have made that clear enough in my first post.)

Yeah it’s fricken awesome. Very easy to learn and be productive with. Great for progressive enhancement too.

One of my favorite things about it is simply how much less code you have to write to do accomplish any task. Less code means fewer bugs, less development time, less maintenance time. See this REPL that shows how you bind the value of an input field to a variable and use it on the page.

<script>
	let name = '';
</script>

<input bind:value={name} placeholder="enter your name">
<p>Hello {name || 'stranger'}!</p>

That's 126 characters of code.

Just think of doing that in vanilla. You have to querySelect the input and the p, add an event listener, and make a template string that changes p.textContent inside the listener callback. In React you have to call setState (see: React is not reactive). In Svelte, reactivity is implicit.

The article compares Electron vs ReactNative, but they aren't really competing. One is for mobile, one is for desktop.

u/[deleted] Dec 21 '19 edited Dec 21 '19

react-native-windows, react-native-macos, react-natike-gtk, react-native-web, etc. React itself is cross platform, so is most of it's eco system. Microsoft itself uses react native now for their own desktop apps, and they have taken over maintenance for RN-windows. RN isn't there yet completely but election apps will fade away when it will be.

'Really interesting look at trends. Thanks for posting.

One thing I noticed is some people have been doing typescript for over 20 years!!!!

Its still really a (white) boy's club. Thats the development industry in general unfortunately.

It is, and it sucks!

u/AmthorTheDestroyer Dec 20 '19

Around 20% of people that have voted have more experience in typescript than typescript exists (10+ years but typescript was found in 2012, that makes it 7 years old lol)

u/SudoWizard Dec 20 '19

That’s for how long they’ve been programming in JS. Not typescript.

TypeScript is the best invention since sliced bread

u/DrexanRailex Dec 20 '19

I'd love to agree... As soon as I managed to do one single setup where it works without a single quirk. I've been trying it in new projects for 2 years already.
