## Description

Snowpack is an ESM-powered frontend build tool and development server that serves native ES modules directly to the browser. By eliminating the bundling process during development, it enables nearly instant server startup and unbundled frontend development.

The project features a framework-aware hot module reload system that preserves component state during updates, with specific Fast Refresh integration for React, Preact, Svelte, and Vue. It also acts as a modern web transpiler, automatically converting TypeScript, JSX, and CSS Modules into browser-compatible code without requiring manual configuration.

The build pipeline can be extended via a plugin system to integrate custom transforms and third-party tools. For deployment, the tool generates optimized production builds, offering minification and optional bundler integration to ensure compatibility with legacy browsers.

The tool provides comprehensive support for importing npm packages, JSON data, WebAssembly files, and various static assets directly into the browser environment.
