You've Gotta Check Out SnowPack...


So like most 2020 developers I used to give 0 fucks about bundlers...

I mean react/next/svelte takes care of it for us right

but then, I started doing this course called threejs journey by brunosimon in which bruno makes us understand why bundlers are important

node_modules meme
TL;DR helps client import node_modules files that are stored on the server


The world's most popular javascript bundler "webpack" has a bunch of disadvantages

  1. It is pretty complex, for context and it took me 2 days to understand and be able to configure webpack on my own
  2. It is kinda really slow cuz it rebuilds and rebundles the files for every change [especially if you want to use typescript]

Here's Recordings of WebPack

Time to Initial Load: 35s

Time to Load Changes: 20s

Enter Snowpack

Snowpackjs has a fundamentally different approach to bundling...
It builds each file and caches it for future use, while webpack rebuilds and rebundles every single time


Snowpack is super easy to configure
here's the config I used in the below test

module.exports = {
  mount: {
    src: { url: "/" },
    public: { url: "/", static: true },
Enter fullscreen mode Exit fullscreen mode

it mounts files in src, public dir to "/" (root directory of served content)

Here's Recordings of Snowpack

Time to Initial Load: 20s

Time to Load Changes: 14ms ๐Ÿ˜ฑ

Most amazingly - Snowpack is programmed in Typescript! Not in Go, not in Rust, not in C++ ... just TS ! So probably it's fast because of it's approach/design, more than because of its implementation per se.

But what happened to all of the other blazing-fast bundlers which were making waves recently (and which were indeed programmed in Go, Rust, C++ and so on)? Would be interesting to compare (hint: follow-up article?)
