Plugins hook into webpack's build lifecycle to do work that loaders cannot, such as optimizing output and managing assets. See Concepts: Plugins for how they fit into a build.

Plugins built into webpack are documented in the API reference. The plugins below are separate packages maintained by the webpack organization.

PluginDescription
minimizer-webpack-pluginMinify and compress assets, with support for several minifiers
diagnostics-webpack-pluginRun ESLint, Stylelint, TypeScript, and other checkers during the build

webpack or the plugins above now cover what these plugins did, so their repositories are archived and they are no longer documented here.
