Force angular cli gz generation - css

Question

I'm trying to get a dist folder populated with the standard files + the .gz version of them. I did ng eject to get the webpack.config.js file so I could add the compression plugin https://github.com/webpack-contrib/compression-webpack-plugin. I added the new CompressPlugin({}) as the last plugin and marked the ejected: false in the .angular-cli.json file.
When I then run ng build I don't get any .gzip/.gz files generated which I would expect have.
Is there something I am missing or doing wrong? The full webpack file (mostly generated by ng new is:
const fs = require('fs');
const path = require('path');
const CopyWebpackPlugin = require('copy-webpack-plugin');
const ProgressPlugin = require('webpack/lib/ProgressPlugin');
const CircularDependencyPlugin = require('circular-dependency-plugin');
const HtmlWebpackPlugin = require('html-webpack-plugin');
const autoprefixer = require('autoprefixer');
const postcssUrl = require('postcss-url');
const cssnano = require('cssnano');
const CompressionPlugin = require("compression-webpack-plugin");
const { NoEmitOnErrorsPlugin, SourceMapDevToolPlugin, NamedModulesPlugin } = require('webpack');
const { NamedLazyChunksWebpackPlugin, BaseHrefWebpackPlugin } = require('#angular/cli/plugins/webpack');
const { CommonsChunkPlugin } = require('webpack').optimize;
const { AotPlugin } = require('#ngtools/webpack');
const nodeModules = path.join(process.cwd(), 'node_modules');
const realNodeModules = fs.realpathSync(nodeModules);
const genDirNodeModules = path.join(process.cwd(), 'src', '$$_gendir', 'node_modules');
const entryPoints = ["inline","polyfills","sw-register","styles","vendor","main"];
const minimizeCss = false;
const baseHref = "";
const deployUrl = "";
const postcssPlugins = function () {
// safe settings based on: https://github.com/ben-eb/cssnano/issues/358#issuecomment-283696193
const importantCommentRe = /#preserve|#license|[##]\s*source(?:Mapping)?URL|^!/i;
const minimizeOptions = {
autoprefixer: false,
safe: true,
mergeLonghand: false,
discardComments: { remove: (comment) => !importantCommentRe.test(comment) }
};
return [
postcssUrl({
url: (URL) => {
// Only convert root relative URLs, which CSS-Loader won't process into require().
if (!URL.startsWith('/') || URL.startsWith('//')) {
return URL;
}
if (deployUrl.match(/:\/\//)) {
// If deployUrl contains a scheme, ignore baseHref use deployUrl as is.
return `${deployUrl.replace(/\/$/, '')}${URL}`;
}
else if (baseHref.match(/:\/\//)) {
// If baseHref contains a scheme, include it as is.
return baseHref.replace(/\/$/, '') +
`/${deployUrl}/${URL}`.replace(/\/\/+/g, '/');
}
else {
// Join together base-href, deploy-url and the original URL.
// Also dedupe multiple slashes into single ones.
return `/${baseHref}/${deployUrl}/${URL}`.replace(/\/\/+/g, '/');
}
}
}),
autoprefixer(),
].concat(minimizeCss ? [cssnano(minimizeOptions)] : []);

I'm using #angular/cli 1.4.4.
Note the main reason why I'm doing that is to improve some SEO recommendations because apparently my vendor.css is 600Kb big and being pointed out in the PageSpeed Ingishts: Your page has 1 blocking CSS resources. This causes a delay in rendering your page. It contains 3rd party css only - actually only bootstrap + font-awesome. Unless there is something else to prevent this I thought of compression. I also thought that the web server would auto compress and serve .gz files but I don't know whether that test would apply.
Any help is much appreciated! Thanks

Answer 1

Only ejected application's build is processed by exposed on the root webpack.config.js file. Application which is not ejected (or set to ejected: false) will completely ignore this webpack.config.js file.
So in order to use gzipped files you will need to work with ejected app and use new npm scripts automatically added to package.json.
Instead of 'ng build', now you should run:
npm run build
