father is an NPM package development tool from the UmiJS ecosystem that builds, checks, and helps publish JavaScript/TypeScript packages. It supports both Bundless (ESM/CJS via esbuild, Babel, or SWC) and Bundle (UMD via Webpack) build modes, generates .d.ts types, and offers persistent caching.

Use cases

• build an npm library to esm and cjs output
• generate umd bundle for a typescript package
• produce d.ts type definitions when publishing a package
• speed up incremental library builds with persistent cache
• prebundle dependencies for a node.js framework
• lint common npm package publishing mistakes
• scaffold jest testing into a library project

When to choose

• you are developing and publishing an npm package and want an opinionated all-in-one build tool
• you need both module (esm/cjs) and umd outputs from one config
• you want fast incremental builds with persistent caching
• you want automatic TypeScript declaration generation

When to avoid

• you are building an application rather than a reusable package
• you need full control over a custom webpack/rollup/vite pipeline
• you rely on experimental dependency prebundling in production-critical workflows
