angular - 由于 Firebase 的 IDBIndex 错误，无法提供服务器呈现的应用程序

问题描述

我的环境

操作系统版本：Windows 10
Firebase SDK 版本：6.0.2

问题

我按照本教程创建服务器端呈现的应用程序。当我尝试使用npm run serve:ssr.

我得到的错误是：

proxyRequestMethods(Index, '_index', IDBIndex, [
                                     ^

ReferenceError: IDBIndex is not defined
    at Module.<anonymous> (C:\Users\eg\dist\server.js:343794:38)
    at __webpack_require__ (C:\Users\eg\dist\server.js:30:30)
    at Module.<anonymous> (C:\Users\eg\dist\server.js:342436:61)

    at __webpack_require__ (C:\Users\eg\dist\server.js:137349:30)

在此之前我收到一个错误window is not defined，所以我添加了以下代码，server.ts如本评论中所述

const domino = require('domino');
const fs = require('fs');
const path = require('path');
const template = fs.readFileSync(path.join(__dirname, '.', 'dist', 'index.html')).toString();
const win = domino.createWindow(template);
global['window'] = win;
global['document'] = win.document;

当我使用构建 ssr 应用程序时npm run build:ssr，我收到如下所示的警告

WARNING in ./node_modules/@angular/fire/firestore/firestore.js 23:21-32
"export 'SDK_VERSION' was not found in 'firebase/app'
 @ ./node_modules/@angular/fire/firestore/public_api.js
 @ ./node_modules/@angular/fire/firestore/index.js
 @ ./dist/server/main.js
 @ ./server.ts

 @ ./node_modules/@angular/fire/firestore/index.js

 @ ./server.ts

此外，当我使用服务（d）应用程序npm run serve:ssr时，我在使用时收到这些警告，我在更新后收到firebase@5.x.x错误，我收到错误reference: self is not definedfirebase@6.0.2

var major = parseInt(firebase_app__WEBPACK_IMPORTED_MODULE_6__["SDK_VERSION"].split('.')[0]);
TypeError: Cannot read property 'split' of undefined

    at __webpack_require__ (C:\Users\eg\dist\server.js:137353:30)

webpack.server.config.js我通过在下面添加行来更新这些警告和错误

  const regex = /firebase\/(app|firestore)/;
module.exports={
externals: [/node_modules/, function(context, request, callback) {

    // exclude firebase products from being bundled, so they will be loaded using require() at runtime.
    if(regex.test(request)) {
      return callback(null, 'commonjs ' + request);
    }
    callback();
  }],
...
}

我还发现了与此错误相关的这个stackoverflow 问题，但我不使用性能模块，因此解决方案不适用于我。

我该如何解决这个IDBIndex错误？请帮忙
