Я следовал многим урокам о том, как уменьшить размер пакета, но ничто не повлияло на размер пакета, и я не знаю почему.
Каждый раз, когда я добавляю новый код в веб-пакет, размер моего пакета остается таким же, как и раньше.
(Мое приложение построено с помощью плагина vue cli 3 pwa, веб-пакета ... и т. Д.)
Если я запускаю npm run build, я получаю этот вывод:
webpack.config.js:
const path = require('path');
const BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin;
const OfflinePlugin = require('offline-plugin');
const webpack = require('webpack');

const WebpackChunkHash = require('webpack-chunk-hash');
const CompressionPlugin = require('compression-webpack-plugin');
