In early development

One command, one dependency and zero configuration to build your libraries.

Built upon Rollup and SWC.

Features

• [ ] Zero configuration with auto detection
  • [x] SWC additional configuration (.swcrc)
  • [ ] Babel (.babelrc or other formats) - we should replace (or add one more step?) swc with babel when we found .babelrc
  • [x] CSS
    • [x] PostCSS (by default if we found postcss.config.js or any other pre-processor)
    • [x] SCSS, LESS, Stylus
    • [x] Modules (my-file.module.css) and global (any other) files
• [x] Beautiful TypeScript support
  • [x] Builds clean TypeScript definitions
  • [x] Support configuration: baseUrl, paths, externalHelpers, target, sourceMap, experimentalDecorators
• [x] Multiple entries and outputs
  • [x] Different outputs: CJS, ESM (.mjs), UMD
  • [x] Single or multiple inputs: file, array, globs and all together
  • [ ] Out-of-box split output on multiple entries
  • [ ] wip package.json update suggestion: exports and typesVersions

Installation and fast setup

Install autobuild with any package manager: yarn add -D @neodx/autobuild / npm i -D @neodx/autobuild.

Describe your package.json:

{
  files: ['dist', 'README.md'],
  scripts: {
    build: 'autobuild src/index.ts'
  }
}

And try to run our CLI: yarn autobuild

Known issues and limitations

Slow TypeScript definitions and CSS build time

We use rollup-plugin-dts and rollup-plugin-postcss, both of them significant slow down the build time.

Probably, we will change our setup with other solutions or even with self-made plugins in future.

Limited CSS support - single file only, no imports in generated code

Unfortunately, currently we can't provide great CSS output :(

Supported features:

• CSS modules (my-file.module.css), global styles
• Scss, less, stylus
• PostCSS configuration
• Minification

Unsupported:

• Multiple entries - see our "advanced-mixed" example
• Import statements in built code, which is required for DX with multiple entries

Temporal milestones

• [x] [rejected] Replace postcss plugin with https://www.npmjs.com/package/rollup-plugin-styles
• [ ] Add support for CSS splitting
• [ ] Research why swc remove .scss extension
• [ ] Fork rollup-plugin-styles
