## What it is
swc-node is a set of packages providing fast TypeScript/JavaScript transformation and execution on Node.js using the SWC compiler, without node-gyp or postinstall scripts. It includes a register hook to run TypeScript directly (like ts-node but without typechecking) and a fast Jest transformer.

## Use cases
- run typescript directly with node without compiling
- faster alternative to ts-node without typechecking
- speed up jest typescript test transforms
- transpile typescript to javascript quickly
- run typescript esm scripts with node
- execute typescript in shebang scripts

## When to choose
- you want to run TypeScript on Node.js with minimal startup overhead and no typechecking
- you need a fast Jest transformer for TypeScript files
- you want a ts-node replacement without native build steps

## When to avoid
- you need typechecking during development (use tsc or ts-node with typecheck)
- your project is not on Node.js
- you need full TypeScript compiler features like emit declarations

## Facets
- artifact type: library

- function: compiler, build-tool, developer-tools, cli
- domain: developer-tools, programming-languages, web-development, performance
- platform: cli, cross-platform
