esbuild-node-externals

An esbuild plugin that automatically externalizes all Node.js built-in modules and dependencies from node_modules, so they are not bundled. Version 1.22.0 supports esbuild 0.12–0.28. It differentiates from manual externals handling by scanning package.json dependencies, devDependencies, peerDependencies, and optionalDependencies, and also externalizes Node built-ins like 'fs', 'path', etc. The plugin handles ESM and CJS outputs correctly, and works well with monorepos. It is often used alongside other esbuild plugins for Node.js bundling where the goal is to keep dependencies out of the bundle for faster builds and smaller output. The package has type definitions built-in and is released on a as-needed cadence.
