snowpack VS swc

Once you build a simple Vite backend integration, try not to complicate Vite's configuration unless you absolutely must. Vite has become one of the most popular bundlers in the frontend space, but it wasn't the first and it certainly won't be the last. In my 7 years of building for the web, I've used Grunt, Gulp, Webpack, esbuild, and Parcel. Snowpack and Rome came-and-went before I ever had a chance to try them. Bun is vying for the spot of The New Hotness in bundling, Rome has been forked into Biome, and Vercel is building a Rust-based Webpack alternative.

Additional features for Bun include a transpiler and package manager. As hinted at in the name, it also includes bundling features, giving you the functionality that would otherwise require another tool, such as Snowpack or rollup.js. It also has a dead code elimination feature through its JavaScript minifier.

Even, there are several bundling tools available, including popular ones like Webpack and Snowpack.

once upon a time there was this thing called Snowpack: https://www.snowpack.devwhich had a lot of promises as vite (rollup w/ esm). So I migrated a project over from CRA to this thing.While startup speed was much much faster, it actually didn't make the app useable. I timed it meticulously for both CRA and snowpack build and found that the TTI was almost identical. I am not claiming the same to be vite but it's possible and I don't have a large app to prove it..

Snowpack.

That reminds me, wasn't there a build tool called Snowflake?

Oh, it was called Snowpack [1]. And it's no longer being actively maintained. Yeesh.

Snowpack app - a single HTML page with Snowpack configuration

The first thing we need is a JavaScript project for our app. We'll use Snowpack as our bundler. Open a terminal located in a directory for the project and type npx create-snowpack-app react-couchdb --template @snowpack/app-template-minimal. Snowpack will create a skeleton for our React application and install all dependencies. Once it's done doing its job, type cd react-couchdb to get into the newly created project directory. create-snowpack-app is very similar to create-react-app in how it sets-up your project, but it's a lot less intrusive (You don't even need to use eject at any point).

Snowpack appears to be no longer maintained.

Before you get too deep into Snowpack, be aware that they recommend using other tools now because it’s no longer maintained.

First, we switched the default compiler for new projects from Babel to SWC (Speedy Web Compiler). SWC is dramatically faster than Babel and requires zero configuration. We’ll continue to support Babel in any project currently using it.

SWC

As the reference explains “**SWC** (Speedy Web Compiler) is an extensible Rust-based platform that can be used for both compilation and bundling. Using SWC with Nest CLI is a great and simple way to significantly speed up your development process.”

This is specifically about breaking the myth that performing expensive self-contained operations (e.g, parsing GraphQL) in a native extension (C, Rust, etc.) is always faster than the interpreted language.

The JS ecosystem has the same problem, people think rewriting everything in Rust will be a magic fix. In practice, there's always the problem highlighted in the post (transitioning is expensive, causes optimization bailouts), as well as the cost of actually getting the results back into Node-land. This is why SWC abandoned the JS API for writing plugins - constantly bouncing back and forth while traversing AST nodes was even slower than Babel (e.g https://github.com/swc-project/swc/issues/1392#issuecomment-...)

Why Speedy Web Compiler ?

FTA is a TypeScript static analysis tool built on the speedy foundations of swc. FTA is fast; capable of analyzing more than 150 files per second on typical hardware, it offers a powerful addition to your code quality toolkit.

Very cool! I'm curious, is this intended for dev tooling?

For example, I could see this (or something similar) being useful as the engine for a typescript language server that would be faster than the standard one

But if it's not aimed at 1:1 with tsc, would it be intended more for something like swc[1]?

Or what would you expect people to use this for, besides just being a cool project to learn from?

This is... good news, but I still cannot fathom using the default Typescript compiler for regular development. Seriously, leave the type-checking to your IDE and CICD chain, and switch to using tsx (https://www.npmjs.com/package/tsx) or swc (https://swc.rs/) and you will _immediately_ notice the difference in speed and productivity.
