{"library":"happypack","type":"library","category":null,"description":"HappyPack accelerates webpack builds by parallelizing file transformations across multiple Node.js worker threads. Version 5.0.1 (last release) is in maintenance mode; the author recommends webpack 4+'s built-in thread-loader for new projects. Key differentiator: it was the first widely-adopted parallel loader for webpack 1-3, but it has limited support for certain webpack loader APIs and is not actively developed. It remains useful for legacy webpack setups where migration to thread-loader is not feasible.","language":"javascript","status":"maintenance","version":"5.0.1","tags":["javascript","webpack","plugin","fast","speed","performance","compilation","transformer","loader"],"last_verified":"Wed May 27","install":[{"cmd":"npm install happypack","imports":["const HappyPack = require('happypack');","use: 'happypack/loader'","new HappyPack({ loaders: ['babel-loader'] })"]},{"cmd":"yarn add happypack","imports":[]},{"cmd":"pnpm add happypack","imports":[]}],"homepage":null,"github":"https://github.com/amireh/happypack","docs":null,"changelog":null,"pypi":null,"npm":"https://www.npmjs.com/package/happypack","openapi_spec":null,"status_page":null,"smithery":null,"compatibility":{"summary":{"python_range":"18–22","success_rate":0,"avg_install_s":null,"avg_import_s":null,"wheel_type":null},"url":"https://checklist.day/v1/registry/happypack/compatibility"}}
