sucrase VS tsdx

Thanks. As for the code compilation, that can be tested and seen in https://sucrase.io/

The demo page is only to show how we can transpile JSX in browsers.

Thanks u/OutlandishnessKey953, the playground built with React, Docusaurus(https://docusaurus.io/), CodeMirror(https://codemirror.net/), Sucrase(https://sucrase.io/), etc.

Hi, Sucrase author here.

To be clear, the benchmark in the README does not allow JIT warm-up. The Sucrase numbers would be better if it did. From testing just now (add `warmUp: true` to `benchmarkJest`), Sucrase is a little over 3x faster than swc if you allow warm-up, but it seemed unfair to disregard warm-up for the comparison in the README.

It's certainly fair to debate whether 360k lines of code is a realistic codebase size for the benchmark; the higher-scale the test case, the better Sucrase looks.

> worse it disables esbuild and swc's multi-threading

At some point I'm hoping to update the README benchmark to run all tools in parallel, which should be more convincing despite the added variability: https://github.com/alangpierce/sucrase/issues/730 . In an ideal environment, the results are pretty much the same as a per-core benchmark, but I do expect that Node's parallelism overhead and the JIT warm-up cost across many cores would make Sucrase less competitive than the current numbers.

First, npm i -D sucrase to install sucrase. Now you can do node -r sucrase/register ./index.ts to run TypeScript code directly with Node.

As you might know there are a lot of Javascript bundlers out there, such as webpack, sucrase, parcel, rollup and etc. Bear in mind, not because they have thousands of stars on Github that means they're the best. sometimes new libs are as good as the popular ones but they're still building up their image/popularity in the community. what I bring today is a not sooooo, popular JS bundler called esbuild.

Sucrase JS was 2x the speed of esBuild and 50% faster than SWC last I checked.

Webpack does way more than esbuild, including running a typechecking compiler instead of just transpiling, running compilers able to downlevel emit to ES5 and providing a deep plugin architecture allowing you to hook into any bit you like. But yes, it hasn't been designed with speed in mind - it has been designed with maximum extensibility instead. Its the same reason why Babel is slow compared to sucrase (written in JS, currently faster than SWC and esbuild but doing somewhat less - https://github.com/alangpierce/sucrase)

tsc has in fact been designed with speed in mind (I've been following the project since before it ended up on GitHub). Going beyond 1 order of magnitude performance improvement is highly unlikely.

tsdx - Zero-config CLI for TypeScript package development

If you’re into TypeScript, I highly recommend https://tsdx.io . I’ve used it to create a package before and it’s so much easier

Thanks for the insight fellas. Aside question, I was thinking of bootstrapping the project with tsdx, but their last release was well over 2 years ago. Wondering if there are any alternative options for creating libraries?

NOTE: If your project uses TypeScript, I would suggest using tsdx instead.

Sadly, it's a bit dead. We switched to dts-cli fork, but tsup looks good too

I don't depend on the actual typescript docs much but thankfully in @types and in tons of repos there are examples of well written typescript code.

The amount of JS and TS out there is also a bit of a foot gun though so stick with heavily used/starred libs if you aren't sure.

One tool that helps a lot with developing libraries in typescript is TSDX[0] or its successor dts-cli[1] and there is a bunch of good stuff in awesesome-typescript[2].

Maybe library devving is harder?(more work?) with tyepscript but it is worth it for the end developer, especially if that end developer is you. If you aren't using your own libs then you're probably getting paid by someone else to make them or... idk.

We will use a TSDX library - this tool is something similar to create-react-app, but for creating components library. It allows as to initialize a project immediately with already set up bundler, Rollup with Typescript supporting, testing with Jest, code formatter, Prettier and Storybook.

May be you need to try https://tsdx.io/

So what is the ideal way to build TypeScript libraries? I've heard that tsdx https://tsdx.io/ is quite good

There’s tsdx. But I’d recommend using Vite and storybook-vite
