This plugin splits minification of webpack compilations into smaller units.
npm install @rushstack/webpack5-module-minifier-pluginThis package contains a plugin for webpack 5 that performs minification on a per-module basis rather than per-asset to deduplicate and parallelize compression work.
npm install @rushstack/webpack5-module-minifier-plugin --save-dev
This Webpack plugin performs minification of production assets on a per-module basis, rather than minifying an entire chunk at a time.
It issues async calls to the minifier for each unique module and each unique set of chunk boilerplate (i.e. the webpack runtime and the structure of the module list).
This improves minification time by:
- Avoiding duplicate work for each module that is included in multiple distinct assets/chunks (this is common with async chunks)
- Handing smaller code chunks to the minifier at a time (AST analysis is superlinear in size of the AST)
- Even single asset builds will likely still contain multiple modules in the final output, which can be split across available CPU cores
[hash] and [contenthash] tokensuseSourceMap) to the plugin, but if altering the minifier property itself, you may need to use the output.hashSalt property to force a change to the hashes, especially if leveraging the MessagePortMinifier or similar, since it has no direct access to the configuration of the minifier.``js
