How to migrate from uglifyjs-webpack-plugin to terser-webpack-plugin

On webpack 5 you can usually delete the plugin entirely, since production mode minifies by default; if you need custom options, configure optimization.minimizer with terser-webpack-plugin.

Why uglifyjs-webpack-plugin is on this list

webpack-contrib archived uglifyjs-webpack-plugin in December 2019, and the README's notice points at terser-webpack-plugin. The last release was 2.2.0 in July 2019 and the plugin only ever supported webpack 4. webpack 5 minifies with Terser in production mode without any plugin entry of your own; note the maintained plugin is now also published under the name minimizer-webpack-plugin.

The succession is settled: primary sources agree and the ecosystem has already moved.
