## What it is
Parcel is a zero-configuration build tool and module bundler for the web, supporting JavaScript, TypeScript, CSS, HTML, images, and many other asset types out of the box. It includes a built-in dev server with hot reloading, production optimizations like minification, tree shaking, and code splitting, and an extensible plugin system.

## Use cases
- bundle a javascript web app without writing webpack config
- build a react or vue application with zero setup
- serve a local dev server with hot module replacement
- bundle a javascript library for npm publishing
- split application code into lazy-loaded chunks with dynamic imports
- compile typescript, sass, and images automatically in one build
- optimize and minify assets for production deployment

## When to choose
- you want a bundler that works with minimal or no configuration
- you're starting a new web app or library and want fast setup
- you need a built-in dev server with HMR and HTTPS out of the box
- your project mixes many file types like HTML, CSS, TypeScript, and images

## When to avoid
- you need deep customization and an extensive plugin ecosystem like webpack offers
- your team already has a mature esbuild or vite setup
- you require framework-specific tooling tightly integrated with a meta-framework

## Facets
- artifact type: library
- maturity: active
- function: build-tool, compiler, cli, http-server, static-site-generator
- domain: web-development, frontend, developer-tools
- platform: cross-platform, cli
- tags: module-bundler, zero-config, hmr, tree-shaking, code-splitting, dev-server, bundler, javascript, nodejs
