/**
|
|
* Repurposed UnminifiedWebpackPlugin.
|
|
*
|
|
* See: https://github.com/leftstick/unminified-webpack-plugin/blob/master/index.js
|
|
*
|
|
* Changes:
|
|
* 1. Remove check for UglifyJsPlugin - Terser is the successor.
|
|
* 2. Remove check for development mode - we always want unminified files.
|
|
* 3. Remove BannerPlugin support - we don't use it.
|
|
* 4. Remove the 'min' suffix from the chunk loaded in the new `mainEntry` option.
|
|
* 5. Hook into compilation later so we're running after Source Map generation. (https://webpack.js.org/api/compilation-hooks/: PROCESS_ASSETS_STAGE_OPTIMIZE_INLINE)
