Microbundle

Works immediately with just a package.json file, eliminating the need for separate build config files like webpack.config.js or rollup.config.js.

Generates CommonJS, ES Modules, UMD, and modern bundles from a single entry, ensuring broad compatibility without manual setup.

Compiles TypeScript files directly with no extra configuration, though it requires setting module and target to ESNext in tsconfig.json for optimal results.

Produces a special modern bundle that preserves async/await and other ES2017+ features for compatible browsers, resulting in smaller and faster code.
