File Content: unminify.js /** * 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. */ const path = require( 'path' ); const ModuleFilenameHelpers = require( 'webpack/lib/ModuleFilenameHelpers' ); const getFileName = ( name, ext, opts ) => { if ( name.match(/([-_.]min)[-_.]/ ) ) { return name.replace( /[-_.]min/, '' ); } const suffix = ( opts.postfix || 'nomin' ) + '.' + ext; if ( name.match( new RegExp( '\.' + ext + '$' ) ) ) { return name.replace( new RegExp( ext + '$' ), suffix ) } return name + suffix; }; class UnminifyWebpackPlugin { constructor( opts ) { const options = opts || {}; this.options = { test: options.test || /\.(js|css)($|\?)/i, mainEntry: options.mainEntry || false, }; } apply( compiler ) { // Hook after asset optimization if we're using a devtool (source map). // @todo: Update to afterFinishAssets for Webpack 5.x? const compilationHook = compiler.options.devtool ?
