HappyPack is a webpack plugin and loader that speeds up initial webpack builds by running file transformations (like babel-loader) in parallel across multiple processes. It is now in maintenance mode, with webpack's native improvements and thread-loader recommended as alternatives.
Use cases
- speed up slow webpack builds
- run babel-loader in parallel
- reduce webpack compilation time
- parallelize file transforms in webpack
- faster initial builds for large JavaScript projects
When to choose
- you are stuck on an older webpack version with slow builds
- you want multi-process loader execution on webpack 2-3
When to avoid
- you use webpack 4 or newer - prefer thread-loader or webpack 5's parallelism
- your loaders rely on unsupported webpack loader APIs
- you need actively maintained tooling
