将 Angular 通用应用程序部署到 Firebase 函数返回错误

Question

我目前正在尝试将我的 Angular 通用应用程序部署到 Firebase 功能和托管。因此我关注this tutorial。

Error: Error parsing triggers: Cannot find module 'require("./server/main")'

Require stack:
- /Users/timfuhrmann/Documents/Entwicklung/norebro/functions/dist/server.js
- /Users/timfuhrmann/Documents/Entwicklung/norebro/functions/lib/index.js
- /usr/local/lib/node_modules/firebase-tools/lib/triggerParser.js

我认为这与webpack.server.config.js 有关。只要我在output 内添加library 和libraryTarget，就会出现firebase deploy 和 npm run serve:ssr 的错误：

...
output: {
    // Puts the output at the root of the dist folder
    path: path.join(__dirname, 'dist'),
    library: 'app',
    libraryTarget: 'umd',
    filename: '[name].js'
},
...

刚开始打开网站时，不会有 HTML 而不是 app-root。但是，一旦您更改路线并导航到不同的组件，就会出现 HTML 而不是 app-root - 怎么会？

Firebase Functions 控制台有时会返回成功执行，有时会返回一些 @type 信息，有时甚至会返回错误：

Answer 1

对于 TypeError: handler is not a function 错误，只需在 server.ts 文件中将 const app = express(); 替换为 export const app = express();
