SWC

SWC is an extensible Rust-based platform for the next generation of fast developer tools. It's used by tools like Next.js, Parcel, and Deno, as well as companies like Vercel, ByteDance, Tencent, Shopify, and more.

SWC can be used for both compilation and bundling. For compilation, it takes JavaScript / TypeScript files using modern JavaScript features and outputs valid code that is supported by all major browsers.

Overview

SWC can be downloaded and used as a pre-built binary, or built from source. Currently, the following binaries are provided:

• Mac (Apple Silicon)
• Mac (x64)
• Linux (x86_64)
• Linux (aarch64)
• Linux (armv7)
• Alpine Linux (also install @swc/core-linux-musl)
• Android (aarch64)
• Windows (win32-x64)
• Windows (ia32)

Download prebuilt binaries

pnpm i -D @swc/cli @swc/core

Transpile JavaScript file and emit to stdout

npx swc ./file.js
