Babel → SWC
easySWC is 20-70x faster than Babel for transpilation. Drop-in replacement for most projects. No plugins needed for TypeScript/JSX.
npm install -D @swc/core @swc/cli && npm uninstall @babel/core @babel/preset-env @babel/preset-typescript @babel/preset-react
SWC config is simpler than Babel. One file for TypeScript + React.
{
"jsc": { "parser": { "syntax": "typescript", "tsx": true }, "target": "es2020" },
"module": { "type": "commonjs" }
}Replace babel with swc in package.json scripts. Jest: use @swc/jest transform.
npm install -D @swc/jest
If you used babel-plugin-* beyond basic transforms, check SWC plugin compatibility. Most popular plugins have equivalents.
