📦 obuild 😯

✅ Zero-config ESM/TS package builder.

Powered by undefinedoxcundefined, undefinedrolldownundefined and undefinedrolldown-plugin-dtsundefined.

The obuild project aims to be the next-generation successor to the current unbuild.

• 🌱 Fresh rewrite with cleanups and removal of legacy features.
• 🚀 Uses undefinedoxcundefined and undefinedrolldownundefined instead of rollup and mkdist.
• 👌 Strict ESM-compliant imports with explicit extensions.
• 🔒 Types are built with isolated declaration constraints.
• 🪦 No support for CommonJS output.

Some differences are not easy to adopt. Developing as a standalone project allows for faster progress and dogfooding in real projects.

Usage

undefinedCLI:undefined

# bundle
npx obuild ./src/index.ts

# transform
npx obuild ./src/runtime/:./dist/runtime

You can use --dir to set the working directory.

undefinedProgrammatic:undefined

import { build } from "obuild";

await build(".", ["./src/index.ts"]);
