Summary

Introduce RemoveDuplicateModulesPlugin.

This plugin can help you remove duplicated modules without SplitChunksPlugin. Some projects may meet problem that rebuild costs too much time, and SplitChunksPlugin is one of the reasons. But without SplitChunksPlugin there are many duplicated modules, so this plugin comes out.

You can use this in development to speed up your rebuild time, and disable splitChunks.

const rspack = require('@rspack/core')
module.exports = {
  optimization: { splitChunks: false },
  plugins: [new rspack.experiments.RemoveDuplicateModulesPlugin()]
}
