{"id":15555,"library":"builderz","title":"Builderz","description":"Builderz is a zero-configuration JavaScript and TypeScript bundler designed for simplicity and efficiency, aiming to streamline the build process for both libraries and applications by minimizing setup overhead. The current stable version is `0.11.0`, with a development cadence that sees frequent minor updates and patch releases, typically addressing dependency updates, performance enhancements like caching, and bug fixes. Key differentiators include its 'zero-configuration' approach, the ability to build packages even with invalid `package.json` files (addressing a common development pain point), support for parallel build tasks for improved performance, and a robust caching mechanism introduced in `v0.10.0`. It supports both CommonJS (CJS) and ES Module (ESM) output formats and offers both a Command Line Interface (CLI) and a programmatic API for integration into development workflows.","status":"active","version":"0.11.0","language":"javascript","source_language":"en","source_url":"https://github.com/jalal246/builderz","tags":["javascript","builderz","get-info","package-sorter","validate-access","corename","mytools","move-position","folo"],"install":[{"cmd":"npm install builderz","lang":"bash","label":"npm"},{"cmd":"yarn add builderz","lang":"bash","label":"yarn"},{"cmd":"pnpm add builderz","lang":"bash","label":"pnpm"}],"dependencies":[],"imports":[{"note":"Builderz primarily uses ESM for its programmatic API.
