this has been eagerly anticipated for so long and is probably the #1 stated reason why people haven't tried out Svelte yet. so glad this is out!

outime• 6 years ago

It definitely was my #1 reason and I'm happy to see this announcement. I'll check Svelte out soon as it already looked quite promising to me.

untog• 6 years ago

Very happy about this. I tried to combine the two a few months ago and it was not a fun experience. Great to know I can give it another go now.

fb03• 6 years ago

I was literally searching for this like, a week ago. Glad to finally see it land in a stable, first-class manner.

nickreese5• 6 years ago

Having talked to a ton of friends about Svelte, Typescript support has always been the biggest push-back for adoption.

Stoked for Svelte to support it.

We've been using Svelte in production and I can't speak highly enough about the developer experience. Absolute game changer for our ssite that use it.

The_rationalist2• 6 years ago

What would it bring in ergonomics and expressivity versus Vue ?

kjksf• 6 years ago

Those things really need to be experienced to be understood, so just try Svelte in a toy project. Or go through the interactive tutorial https://svelte.dev/tutorial/basics

I used both React and Vue and am now only using Svelte.

You type less. Significantly less.

The thing you type is simpler. I tend to get lost in Vue's object structure.

What you type is closer to HTML/CSS/JavaScript than what you type in React/Vue. It's therefore easier to understand what gets generated.

The seamless reactivity is awesome.

Scoped CSS support is built-in so you don't need css-in-js hacks.

Built-in support for data (stores) is excellent.

The final bundle is smaller and faster.

There's more but the above are the major points.

The only downside is smaller ecosystem. But I don't care because I'm in the camp of minimizing my dependencies.

nickreese5• 6 years ago

I haven't used Vue extensively since what was probably v1 so I'm likely the wrong person to comment on this.

That said, I find that Svelte aligns more with my/our team's mental model about how the web should work and that is why went with it for our sites.

Just like with Vue you can write your JS/CSS/HTML in a single file, but the reactivity and state management is much easier to reason about than what we've seen elsewhere.

- `$:` is great.

- Stores and derived stores are amazing.

- Data binding / rerendering is really intuitive.

That said, the biggest headache in building our own SSG was getting SSR/Hydration working well, but that was mainly fighting Webpack and got easier when we went with Rollup.

edit: formatting.

G4BB3R• 6 years ago

Do you use pure svelte or with sapper? how is it compared to react?

nickreese5• 6 years ago

We wrote our own SSG for https://elderguide.com. We tried Sapper but our data flow and routing needs were to complex and not a fit.

Svelte is a dream compared to React. That said, I've never felt like React was the right solution for the problem.

I've extensively used Gatsby and for static sites, React is absolutely overkill. For apps it can be nice.

In both cases my go-to these days is Svelte.

rawoke0836002• 6 years ago

I LOVEE Svelte, if your any sort of dev... try it out. It's a super small API, you can learn in a few hours. I'm not a frontend dev by trade, but compared to Angular(prev fav) it's soo much simpler.

Vinnl6• 6 years ago

It's really telling that, for every big project that does not support TypeScript, the number 1 feature request is TypeScript support. (And consequently, that there are fewer and fewer such projects.)

swyx4• 6 years ago

indeed we are in a new age of javascript now. one where TS support is (in practice) not optional. https://www.swyx.io/writing/js-third-age/

novok• 6 years ago

Might as well make it part of the language officially and get rid of the need for transcompliers.

hajile• 6 years ago

We really need a "use types" mode.

Instead of trying to support all the super-dynamic parts of JS, those parts should just go away in typed mode. Unlike TS, the type system should be sound. Hindley-Milner with immutable by default and options instead of null with structural typing everywhere and typeclass module definitions.

I guess that's just StandardML with JS syntax, but that would be an amazing language to work with -- far better than either TS or ReasonML.

moltar• 6 years ago

I basically haven’t written any JS code in over two years at this point. Everything I do is TypeScript. When I pick libraries I make sure they have TypeScript support. Preference goes to TypeScript-written packages.

koolba• 6 years ago

Preference goes to TypeScript-written packages.

Indeed, the only thing worse than no typings is wrong typings.

tester7563• 6 years ago

I think that's just proof that "the next future" of web development is going to be owned by languages like C# (that __already__ allow you to write decent client side web apps) and other already popular not dynamic languages

After C# of course yet another DSLs.

cageface6• 6 years ago

Typescript can seamlessly interop with existing JS libraries. This is a huge advantage over any non-JS language.

rubber_duck• 6 years ago

I came to TS after years of C#, all the way back to .NET 2.0 and WinForms.

TBH TypeScript is just better than C# for the job it does - DOM control and gluing data - structural typing that's backed by a dynamic runtime is a much better fit for those kinds of tasks than a nominal type system backed by IL level type checking - AutoMapper is nonsense created by this design decision and C# is particularly verbose (almost Java level).

C# allows you to get much lower level than TS can, you can control memory layout, allocation patterns, you have proper threading model, etc. etc.

But for dealing with single threaded DOM event loop, stitching data from all kinds of sources, simple transformations and sending it around - IMO TS is a better fit.

k__2• 6 years ago

I hope not.

C# is too bloated for my taste and I have to admit, TS is too close to C# for my taste.

joshstrange3• 6 years ago

I won't pretend tsconfig/webpack or any other bundler out there is "fun" to work with but once I get my TS support working in a project it is a joy to write in TS. I already liked JS (if that didn't make you hate me I like PHP too and have gotten paid to write it for a decade now) but TS really pushed me over the top.

I avoided TS like the plague because I didn't want another layer added in and I thought it was just coffeescript++ but after taking the plunge on 6to5 (renamed to babel) because "well these features are coming to JS soon anyway or have already landed in stable browsers" it was just a hop, skip, and a jump over into TS (in for a penny...). Modern JS is actually really fun to work in and TS takes to the next level with peace of mind I never had with just JS.

_zllx2• 6 years ago

I won't pretend tsconfig/webpack or any other bundler out there is "fun" to work with

For me, Parcel is fun to work with. Rollup is my favorite for more advanced or customized pipelines, but Parcel has a silky smooth workflow for the typical bundling tasks in most projects. I've started using it for Node.js as well (since I want to avoid ts-node) but it seems best for frontend-only projects and components. Speaking as someone who has managed to avoid Webpack thus far despite its status as the "industry standard".

pjmlp3• 6 years ago

Because it comes down to what I advocate, guest languages only look nicer on the surface, they add up more layers to debug, extra tooling to integrate, FFI to platform and library wrappers for idiomatic code.

Since the Web platform isn't going away from JavaScript anytime soon, and WebAssembly is relatively constrained beyond WebGL, that leaves UI frameworks as the possible "platform".

What I am looking for is that the adoption will keep carrying on, to the point that browser natively understand Typescript, or WebIDL for that matter.

Vinnl6• 6 years ago

Browsers don't need to understand TypeScript, but just be able to ignore TS-specific syntax like Babel does. Then it's really possible to use TypeScript like a linter without requiring a bundler.

But of course, that'll add quite a drag on TypeScript development. With Babel, they can just maintain the plugin themselves; with browsers, they'll have to go through the standardisation track for every syntax change they want to make.

The_rationalist2• 6 years ago

How is Webstorm support with Svelte ?

mrath• 6 years ago

I believe there is no official plugin for Svelte. So it may not be as good as the support for React/Angular/Vue. But once Svelte is a bit more popular, I think JetBrains will release a plugin.

BMorearty• 6 years ago

Not bad. I’ve been using the Svelte plugin by Tomasz Błachut. But I don’t think the plugin supports TypeScript yet.

wirahx3• 6 years ago

Easier, due to the language-server Svelte uses to support TypeScript. It should be relatively trivial for somebody to implement now.

drol3• 6 years ago

Great news!

Was my only blocker :)

dboreham• 6 years ago

Switching from JS to Typescript was like moving from machine code to C. Note: machine code (hex) not assembler.

DaiPlusPlus• 6 years ago

JavaScript is getting more “typed” anyway - what with Promises and other objects/interfaces in the DOM being conceptually statically typed - where JavaScript’s type-juggling simply can’t help you - so writing JavaScript today against modern browser/NodeJS APIs feels like writing VBScript against ActiveX instead of writing in VBA/VB6: you can do essentially the same things, but you have no idea if your program will actually work or not.

It would not surprise me if the ECMAScript folks just throw in the towel and adopt TypeScript into ECMAScript as its official type-annotation feature - like how Python is doing - except without the duplication of effort.

zamalek4• 6 years ago

I've been using Svelte TS for a pet project for maybe 2 weeks now. It's fantastic. The VSCode plugin is also doing a great job.

I tried, and failed, to use Babel as the TS compiler - but TSC then Babel works just fine.

zeroc8• 6 years ago

Would love to use it, but I need something comparable to PrimeNG. Are there any comprehensive UI toolkits out there already?

widgetic• 6 years ago

seanwilson• 6 years ago

Are the HTML templates type checked as well?

I'm playing with Vue version 3 with TypeScript using JSX instead of the usual HTML templates and pretty happy that it's all type checked. I have a similar project without JSX and the vast majority of the bugs are related to the logic in the HTML templates not being type checked.

dlbucci• 6 years ago

This has been my experience with AngularJS 1 and TypeScript as well. Looks like there's at least some support for it (Quote the link: You get autocompletion hints and type-checking as you're writing components, even in expressions inside markup). Not sure if it does things like restrict `value` to `input` elements or anything, or if it's just the expressions in the template.

smt882• 6 years ago

Try using Vue in WebStorm with their Vue plugin enabled, or use TSX with any IDE. Your "HTML" will be type-checked.

joshstrange3• 6 years ago

Hmm, I'm going to have to take another look at this then because I get auto-complete of variable properties in my html (IDEA + Vue plugin) but I don't get warnings about a variable possibly being null or undefined. But that may be outside the realm of possibility to check easily.

raihansaputra• 6 years ago

Vue with TS, on VSCode and Vetur, with Vetur Template Interpolation enabled (VTI) also typechecks the template.

swyx4• 6 years ago

vosper• 6 years ago

Lack of Typescript support was the main reason I didn't switch to Svelte for my personal projects. Other than that it was a joy to use, and a breath of fresh air in it's approach.

I'd recommend any front-end dev to give Svelte a try, even just spending an hour or two messing around, to experience a way of developing web apps that's likely a bit different to what you're used to, but feels familiar enough that it doesn't require a big mental leap.

wry_discontent3• 6 years ago

I feel like the odd man out in discussions like these. I don't like Typescript and I regret pushing to integrate it into a project at work.

I've found it vastly increases incidental complexity and affords little to no benefit to me. The IDE completions are nice, but ultimately not worth the price, in my humble and honest opinion.

ipnon• 6 years ago

How large is your TypeScript project? What were your type issues before you integrated?

My work has benefited from TypeScript because we can now propagate changes to our unstable API throughout our medium sized application using the compiler. We are fairly certain that all of our components are integrated if the compiler is silent. Before this certainty, we would frequently push broken API integrations to production.

The complexity of TypeScript doesn't seem to benefit projects that are already clean and tested. TypeScript gave us some confidence of correctness when we had disorganized code and inadequate test coverage.

wry_discontent3• 6 years ago

It's about 20kloc.

I encounter seemingly nonstop opaque type errors that come usually when I upgrade TS versions. I'll stipulate this was mostly written when we decided to add TS, and I was new to TS when I added it, but I tried really hard.

As an example, it took me a full week to properly add type definitions to a HOC, and I had to rope in a couple other engineers across that time who had more TS experience. Eventually I got it working, but decided to deprecate the HOC cause the file exploded from being about 50loc to well over 250.

cageface6• 6 years ago

After working in Typescript for 18 months I've moved onto a new Rails project and I miss type checking so much every single day. There are so many dumb bugs that have slipped their way into production that would have been caught by type checks and null checks. It's professionally embarrassing for the client to see this stuff that would have been stopped by better tools.

genuine_smiles• 6 years ago

Have you looked at Sorbet?

https://sorbet.org/

toastercat2• 6 years ago

I also disliked my time with TypeScript, but perhaps its value hasn't made itself entirely apparent to me. Most of my programming experience has also been with dynamically typed languages. I think if you had already spent enough time with a language like JavaScript or Lua and familiarized yourself with its quirks/footguns, you learn how to avoid the common pitfalls of not having a strict type system.

Although I've found that TypeScript is a great way to attract devs who hate JavaScript to try working on front-end.

cageface6• 6 years ago

When working with devs that have grown up on dynamically typed languages I often find that they have not really thought carefully about the structure of their data and there are essentially many ad hoc data types strewn throughout the code. Thinking in types from the beginning leads to much better structured code and stronger abstractions IMO.

mekster5• 6 years ago

What editor are you using? If you don't use an editor that supports TS, then it's all moot.

Editors are meant to auto complete any parameters that you have typed as well as provide errors that don't fit to your typing.

Using editors like vim wouldn't work.

camgunz• 6 years ago

Yeah by the numbers I like it (sum types!), but what put me off is in practice, TS is built for autocomplete. If you aren’t using that, it’s a real pain to guess what type you need to say, and you’re basically digging through code or bad/old docs to find out.

I also found the typing to not really help. Non-null stuff is nice, but without range types, I don’t think the trade off is worth it. It helps about as much as Go’s type system but asks you to do 3x the work, restrict yourself to typed libraries, and setup some pretty tricky tooling.

qudat2• 6 years ago

The real benefit is with refactoring. It is built-in testing. If I change an interface because a business requirement changed, I immediately follow a trail of errors that I need to fix. If types are setup properly, making major changes is dramatically simpler to accomplish.

orange89• 6 years ago

TS was designed to solve a problem. If you cannot see the problem, then you do not need it. Unless when working in teams with devs more used to thinking and structuring their code around types.

mekster5• 6 years ago

Actually TS shows you the problem when you hadn't realized.

Use it with a proper editor that supports TS like VS code or IntelliJ and figure it out.

schwartzworld3• 6 years ago

HN has a high proportion of experienced programmers coming from typed languages. If you are a C# dev who has to write JS, I'm sure typescript is a breath of fresh air, but from where I stand it's awful. The whole point of TS is to reduce the friction in writing JS for those people.

However, from where I stand, Typescript sucks. Sucks sucks sucks. It takes everything I love about JS programming and turns it into suck.

jedimastert• 6 years ago

I am a (very) hobbyist web dev, almost always working with vanilla HTML+JS. I seeing a while lot of people here who are saying that Typescript is an absolute must.

As someone who has no clue, and with all do respect, why would TypeScript be worth moving from just hitting save to introducing a build system and dependencies?

gameswithgo• 6 years ago

in your use case it probably isn’t worth it. if you get a bigger project where you are using webpack and npm already, maybe it would be.

xupybd• 6 years ago

Hobby projects are served very well by js. Commercial ones not so much. Big teams with a mix of Personalities mean you get lots of errors and problems organising code. Typescript makes that a little more manageable.

acemarke• 6 years ago

I talked extensively about the pros, cons, and tradeoffs in my post "Learning TypeScript as an App Dev and Library Maintainer":

runarberg2• 6 years ago

I have been using TypeScript in JS[1] mostly seamlessly. Types are annotated using doc comments above the thing your annotating.

It is a bit hard to define complex types. E.g. I couldn’t for the life of me annotate the return value of the pipe function:

    function pipe(init, ...ops) {
      return ops.reduce((acc, op) => op(acc), init)
    }

For these instances they suggest writing a declaration file[2]. However I have found the documentation isn’t really clear on this usecase (in fact I find the documentation of TypeScript somewhat lacking in general).

But overall getting these typehints into my editor environment has been worth it. And I haven’t had to sacrifice the save → run workflow.

1: https://www.typescriptlang.org/docs/handbook/type-checking-j...

2: https://www.typescriptlang.org/docs/handbook/declaration-fil...

EDIT: An example annotated JS file for typescript: https://github.com/runarberg/strawberry-router/blob/master/s...

`npm run check` just runs typescript’s type checker, there is no compile step.

bgschiller• 6 years ago

E.g. I couldn’t for the life of me annotate the return value of the pipe function

Don't feel bad, no one can do that (yet! I think it should be possible with Variadic Tuple Types, coming in TS 4). There are a couple of attempts[1][2], but they all lack in some way. Redux does it with a boatload of overloads [3].

xsmasher• 6 years ago

If I understand your pipe function correctly - it takes an init value and a series of functions that map a type T to the same type T - then this should do it.

  function pipe<T>(init: T, ...ops: ((x: T) => T)[]): T{
    let r:T = ops.reduce((acc:T, op) => op(acc), init);
    return r;
  }

I had 5 years experience fixing type errors in C++; typescript seems like a dream in comparison.

Edit: I just realized your operations probably DON'T return the same type that they are passed; they probably work in a chain like (t:T) => U, then (u:U) => V, etc. Nevermind!

cageface6• 6 years ago

I get almost as much benefit from the rigorous null checking in TS as I do from the typing. I would use it for that alone.

TiredGuy• 6 years ago

As someone who has used all kinds of tooling and typescript too but still goes back to vanilla js when possible, I relish being able to just hit save and refresh. Build steps and hot-reloading are annoying and complex, and with large projects they can sometimes become slow and frustrating.

Please don't feel pressured to make your code more defensive by switching to a typed language. There is often a tendency to make things more complex in the name of safety especially when there's typing involved, and it's not always the right answer. Clean, readable, maintainable code can exist in dynamically typed programming languages, and don't let anyone tell you differently.

The right balance between over- and under- engineering is something that changes based on who you work with and for, what you're truly trying to accomplish, when you need it by, how quickly you can iterate, and your own personal feelings of safety and joy of programming.

kylemh2• 6 years ago

Everything we do is written in Svelte + Sapper, not just our site, but all the backend apps as well that we use for admin + providers.

aabbcc12414• 6 years ago

In my previous experience of "Svelte with Typescript", it merely remove the typings, no type checking at all.

Try in below example, it print out '12' without type related error message.

aabbcc12414• 6 years ago

Another direction of using typescript based DSL languages that compiles to svelte code seems more maintainable. Checkout https://github.com/mistlog/svelte-draft

cetra3• 6 years ago

I've just tried this using the starter project they provide in the blog post, and it does catch the error:

The error returned is `Type '"1"' is not assignable to type 'number'.`

aabbcc12414• 6 years ago

Thanks for pointing out. It's getting better overtime! I missed the existence of "svelte-check". I expected to see errors on the webpage like we usually see from angular/react/stencil.

On svelte, the typescript error doesn't show up until you manually run svelte-check.

benmccann• 6 years ago

The VS Code extension will surface type checking errors for you or if you want to surface them on the command line you can run https://www.npmjs.com/package/svelte-check

aryonoco• 6 years ago

Rich Harris (the creator of Svelte) just released a short 5 hour video course on Svelte on Frontend Masters as well. It's great intro and touches most common usecases and briefly introduces Sapper as well. If you already have a FEM subscription, this is a great time to get into Svelte.

nXqd• 6 years ago

Yes, finally.

JadoJodo• 6 years ago

Slightly off-topic but I'm curious anyway: Has the tooling for JavaScript improved with TypeScript's adoption? As a back-end developer, I feel like each time I've tried to dig in and start a JavaScript project from scratch has ended with me weeping after spending four hours fighting the tooling. Is there a better way?

tmpz22• 6 years ago

IMO the issue has to do with linting and editors i.e. "how do I make the yellow squigglies go away" or silent compiler warnings in the console due to several layers of default linting rules again applied by your editor, or your React CLI, or your operating systems package manager. These are very unsexy problems that nobody has been able to solve over the past 5 years because ultimately they are opinionated.

symlinkk• 6 years ago

Just use create-react-app, it’s not hard.

crooked-v• 6 years ago

I'd personally recommend Next.js instead. It's even more painless, seamlessly handles a lot of other concerns (like routing), and can be used both as an SSR server and to generate purely static HTML bundles.

qudat2• 6 years ago

It's about the same as any other service, the only difference is every web app needs js. Try jumping into a python web service and talk to me about weeping from terrible tooling.

hath995• 6 years ago

I start all my server side projects in TypeScript lately. There is enough support that it is actually very easy to get started. ts-node, npm @types, and many packages natively supporting ts help.

The browser is a crazy environment and adds difficulty, but I find my server code can very strictly typed. The nodejs type definitions are good and if you pick an ORM library with good typescript support then both the in memory data structures and database objects can be well typed.

The build step with typescript is basically negated by ts-node for the server. Alternatively, by using tsc --watch and some clever indirection I've enabled hot reloading for most of my server code. So just to be clear, I have types helping me code using vs-code, I save and immediately see changes on the server.

If you know the tools well and how to set things up then TS + node can provide a better developer environment than many languages.

leejoramo• 6 years ago

Unlike many who have not used Svelte due to lack of Typescript support, this may give my team reason to consider Typescript.

orange89• 6 years ago

This.

I suspect there is a certain way those who rave about TS like yourself write and structure their code (all code, regardless of language) in a way that naturally lends itself to strict typing. The "rigorous null checking" comment struck me as odd, as someone who has written JS for almost 20 years, I've just never had to think about, or use null values. I probably just use the good parts of the language and avoid the bad [2]

spion3• 6 years ago

You can't avoid null and undefined in your code unless you avoid almost every language feature. Two particularly common ones:

* Accessing a missing property or method results with undefined. Hope you remember the exact method names and field names of all objects in your codebase!

* Using "str".match(regex) results with null if there are no matches.

orange89• 6 years ago

You can't avoid null and undefined

We are speaking about just null, not "null and undefined". Believe it or not, I simply do not use null in JS. Study the concept of "truthy and falsy" in JS.

Accessing a missing property or method results with undefined. Hope you remember the exact method names and field names of all objects in your codebase!

I don't. I do however structure my code predictably, using consistent naming conventions and patterns. I hope you do realize JS existed for over 20 years before TS, and complex apps like gmaps and google docx were built entirely in JS.

Using "str".match(regex) results with null if there are no matches.

const match = /bar/.exec("str");

if( match ){

  // am only interested in what happens if foo returns a *truthy* result.
 
  // The exact type of a falsy result is irrelevant, it either matches (truthy) or it doesn't (falsey)

}

nojvek2• 6 years ago

TS really shines when you have to work with other people’s code. This week I probably touched about 2000+ files and changes various apis. TS was really great in giving that confidence that what I am calling actually existed.

I had ~2000 errors and slowly worked to 0. tsc —watch is so good for iterative development.

And LSP (Language Server Protocol) really is a boon for the industry. So many tools can work together. Thank you VSCode for paving the way to an open protocol.

nojvek2• 6 years ago

Svelte is nice, but man I just want to use JSX. Don’t make me learn another templating language.

wirahx3• 6 years ago

Svelte will never have JSX, not natively anyway. It's completely against the philosophy.

Not all of us think JSX is a great thing. The "templating" language in Svelte isn't really a templating language at all, it's just Javascript with some (unavoidable) helpers. It takes about 2 minutes to learn since there are really only maybe 5 helpers.

ric2b• 6 years ago

Svelte templates aren't really a new language, it's just HTML where you can sprinkle in some curly braces to insert variables or js code.

aabbcc12414• 6 years ago

You can dev Svelte in TSX with svelte-draft

heapslip• 6 years ago

Just so you know svelte + typescript + eslint is currently not working.
