An extremely fast bundler for the web
Next-generation ES module bundler
Build system optimized for JavaScript and TypeScript, written in Rust
Quick Overview
Snowpack is a modern, lightweight build tool for web development. It leverages JavaScript's native module system (ESM) to provide a faster, more efficient development experience compared to traditional bundlers like webpack or Parcel.
Pros
- Fast development builds with near-instant startup times
- No bundling required during development, resulting in quicker refresh times
- Built-in support for TypeScript, JSX, CSS Modules, and more
- Optimized production builds with tree-shaking and code-splitting
Cons
- Relatively new compared to more established build tools
- May require additional configuration for complex projects
- Some plugins and integrations might not be as mature as those for other build tools
- Learning curve for developers accustomed to traditional bundling workflows
Code Examples
- Basic Snowpack configuration (snowpack.config.js):
module.exports = {
mount: {
public: '/',
src: '/dist',
},
plugins: [
'@snowpack/plugin-react-refresh',
'@snowpack/plugin-dotenv',
],
};
- Using Snowpack's built-in optimization for production builds:
// snowpack.config.js
module.exports = {
optimize: {
bundle: true,
minify: true,
target: 'es2018',
},
};
- Importing CSS as a module in a React component:
import React from 'react';
import styles from './Button.module.css';
function Button({ children }) {
return <button className={styles.button}>{children}</button>;
}
export default Button;
Getting Started
- Install Snowpack:
npm install --save-dev snowpack
- Add Snowpack scripts to your package.json:
"scripts": {
"start": "snowpack dev",
"build": "snowpack build"
}
- Create a basic HTML file (index.html) in your project root:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<title>My Snowpack App</title>
</head>
<body>
<div id="root"></div>
<script type="module" src="/dist/index.js"></script>
</body>
</html>
- Create a JavaScript file (src/index.js) and start developing:
console.log('Welcome to Snowpack!');
- Run the development server:
npm start

// snowpack.config.js
module.exports = {
plugins: ['@snowpack/plugin-react'],
buildOptions: {
out: 'dist',
}
}

Vite generally offers better performance and more built-in features, while Snowpack provides a simpler, more flexible approach. The choice between the two often depends on specific project requirements and developer preferences.
A bundler for javascript and friends. Packs many modules into a few bundled assets. Code Splitting allows for loading parts of the application on demand. Through "loaders", modules can be CommonJs, AMD, ES6 modules, CSS, Images, JSON, Coffeescript, LESS, ... and your custom stuff.
Pros of webpack
- More mature and widely adopted in the industry
- Extensive ecosystem of plugins and loaders
- Supports complex bundling scenarios and code splitting
Cons of webpack
- Steeper learning curve and more complex configuration
- Slower build times, especially for larger projects
- Requires more setup for modern web development features
Code Comparison
webpack configuration:
module.exports = {
entry: './src/index.js',
output: {
filename: 'bundle.js',
path: path.resolve(__dirname, 'dist'),
},
module: {
rules: [
{ test: /\.js$/, use: 'babel-loader' },
],
},
};
Snowpack configuration:
module.exports = {
mount: {
public: '/',
src: '/dist',
},
plugins: [
'@snowpack/plugin-react-refresh',
],
};
Snowpack offers a simpler configuration and faster development experience, especially for modern web applications. It leverages native ES modules and provides near-instantaneous startup times. However, webpack remains a powerful and flexible tool for complex bundling needs and has a larger ecosystem of plugins and integrations. The choice between the two depends on project requirements, team expertise, and development priorities.
The zero configuration build tool for the web. 📦🚀
Pros of Parcel
- Zero configuration: Parcel works out of the box without requiring any setup
- Faster build times: Parcel's build process is generally quicker than Snowpack's
- Broader asset support: Handles a wide range of file types natively
Cons of Parcel
- Larger bundle sizes: May produce larger output files compared to Snowpack
- Less flexibility: Fewer configuration options for advanced use cases
- Slower hot module replacement (HMR): HMR can be slower than Snowpack's
Code Comparison
Parcel:
// No configuration needed, just run:
parcel index.html
Snowpack:
// snowpack.config.js
module.exports = {
mount: {
public: '/',
src: '/dist',
},
};
Parcel requires no configuration to get started, while Snowpack typically needs a basic configuration file. Snowpack's approach offers more control but requires additional setup. Parcel's simplicity makes it ideal for quick prototypes or smaller projects, while Snowpack's flexibility suits larger, more complex applications. Both tools aim to simplify the build process, but they achieve this goal through different approaches.
