# Microbundle

Zero-configuration bundler that builds small JavaScript libraries into CommonJS, ES module and UMD bundles, powered by Rollup.

STUB. This software has no release or pre-release in four years, or its project site no longer shows it, so it is not part of the register, not counted and not indexed. It will be checked again.

## Notes

Microbundle is a bundler for small JavaScript libraries, built on Rollup. It writes CommonJS, ES module and UMD bundles for the same source, using the output fields of the project's package.json.

The build can be run once with the microbundle command, or with a watch mode that rebuilds when source files change. Babel handles ESnext and async/await syntax, and Terser compresses the output. TypeScript sources are supported without configuration.
