esbuild-plugin-rdi

0.0.0 verified Fri May 01 auth: no javascript

An esbuild plugin that removes duplicate require statements from minified builds, reducing bundle size by eliminating redundant module imports. Version 0.0.0 is the initial release. It integrates seamlessly with esbuild and tsup, supporting TypeScript out of the box. Key differentiator: focuses specifically on duplicate require removal in esbuild, filling a niche gap in build optimization. Development is active with no breaking changes yet.

await esbuild.build({

  minify: true,
  format: 'cjs',
  plugins: [rdiPlugin()]
});
