当我尝试workbox和angular时，我得到了一个奇怪的错误。
一直在遵循工作盒的指南和文档，也在寻找答案，但找不到任何适合我的解决方案。
无论如何，我得到了这个错误错误:不能找到自我。__WB_MANIFEST .
当我创建service-worker.js时，代码为
service-worker.js
import { precacheAndRoute } from "workbox-precaching";
import { registerRoute } from "workbox-routing";
import { StaleWhileRevalidate } from "workbox-strategies";
import { BroadcastUpdatePlugin } from "workbox-broadcast-update";
// Use with precache injection
precacheAndRoute(self.__WB_MANIFEST);
registerRoute(
({ url }) => url.pathname.startsWith("/"),
new StaleWhileRevalidate({
plugins: [new BroadcastUpdatePlugin()],
})
);
但是如果我注释掉StaleWhileRevalidate的导入，它就可以工作了。
import { precacheAndRoute } from "workbox-precaching";
import { registerRoute } from "workbox-routing";
// import { StaleWhileRevalidate } from "workbox-strategies";
import { BroadcastUpdatePlugin } from "workbox-broadcast-update";
// Use with precache injection
precacheAndRoute(self.__WB_MANIFEST);
registerRoute(
({ url }) => url.pathname.startsWith("/"),
new StaleWhileRevalidate({
plugins: [new BroadcastUpdatePlugin()],
})
);
有人知道为什么会发生这种情况吗?
我要用inject manifest方法。
webpack.config.js
const { InjectManifest } = require("workbox-webpack-plugin");
module.exports = {
// Other webpack config...
plugins: [
// Other plugins...
new InjectManifest({
swSrc: "./src/service-worker.js",
}),
],
};

最后我解决了这个问题，似乎@angular-builders/custom-webpack和@angular-devkit/build-angular之间的版本差异破坏了构建。也许它会帮助别人。
