## What it is
tsx is a Node.js enhancement that runs TypeScript files directly, acting like an alias to node with esbuild-powered transpilation. It supports CJS/ESM interop, tsconfig paths, and a watch mode for fast development iteration.

## Use cases
- run a typescript file directly without compiling
- replace ts-node with a faster typescript runner
- run typescript scripts in node with no config
- watch and re-run a typescript file on save
- import esm packages from a commonjs project
- quickly execute a .ts script with npx

## When to choose
- you want zero-config TypeScript execution in Node.js
- you need fast startup via esbuild instead of ts-node
- you want built-in watch mode for development
- you need CJS and ESM interoperability

## When to avoid
- you need type-checking at runtime (tsx strips types without checking)
- you're bundling for production rather than running directly
- you're targeting runtimes other than Node.js like Deno or Bun

## Facets
