Question

我遵循了https://developers.google.com/web/tools/workbox/guides/using-bundlers上的步骤，但是构建后的dist/sw.js文件根本没有被Webpack处理。所有导入语句仍然保持不变，Terser不会删除注释，也不会使其变得丑陋。

我做错了什么？应该sw.js首先构建为单独的条目，然后将输出传递给插件吗？

dist / sw.js（实际输出，除了注入的第一行外，没有任何处理）

importScripts("/dist/precache-manifest.f26179340acee9ac29fc6c689e5cb0c5.js", "https://storage.googleapis.com/workbox-cdn/releases/4.3.1/workbox-sw.js");

import { registerRoute } from 'workbox-routing'
import { CacheFirst, NetworkFirst } from 'workbox-strategies'

import { setConfig, skipWaiting, clientsClaim } from 'workbox-sw'
import { Plugin as BroadcastUpdatePlugin } from 'workbox-broadcast-update'
import { Plugin as ExpirationPlugin } from 'workbox-expiration'
import { Plugin as CacheableResponsePlugin } from 'workbox-cacheable-response'

        // worker code does not need to be transpiled to ES5.

Answer 1

我们正在积极地为InjectManifest插件进行重写，除了填充预缓存清单之外，该插件还将在swSrc上执行webpack子编译。
