worker-loader

Webpack loader for bundling Web Workers as separate files or inline blobs. Version 3.0.8 is the latest stable release (Feb 2021). Actively maintained as part of the webpack-contrib ecosystem. Key differentiators: supports inline workers via BLOB to avoid separate HTTP requests, allows customization of worker constructor (Worker/SharedWorker), and provides fine-grained control over filename, publicPath, and esModule output. Requires webpack 4 or 5 and Node >=10.13.
