如何在 Google App Engine 上为后端 api 运行 Angular 通用应用程序和单独的节点应用程序？

Question

I hope someone out there can help me out!

I have an Angular Universal app which I have deployed to Google App Engine.

I have an app which is running on the default instance of the GAE and it has its own custom domain that I've configured.

So now I want to run a separate node app which is basically just an express server with a mail api endpoint (/api/sendmail) to send mails.

This endpoint will be running on http://localhost:3000/api/sendmail. Below are all my files.

When I hit the endpoint /api/sendmail , and I check the logs using gcloud app logs tail -s servicename, it logs out app.listen(3000, () => { console.log("The server started on port 3000");}); .

But it doesn't seem to run the following. It doesn't run the console log?

app.post("/api/sendmail", (req, res) => {
    console.log("Got Request");
}

My package.json has these scripts

"start": "node dist/server",
"deploy": "ng build --prod && npm run build:ssr && gcloud app deploy --quiet && gcloud app deploy dispatch.yaml --quiet",

Proxy.conf.json file has this

{
    "/api": {
        "target": "http://localhost:3000",
        "secure": false,
        "logLevel": "debug",
        "pathRewrite": {
            "^/api": ""
        }
    }
}

App.yaml

runtime: nodejs10

handlers:
    - url: /.*
      secure: always
      redirect_http_response_code: 301
      script: auto

dispatch.yaml

dispatch:
    - url: "*/api/*"
      service: lunr-app-backend

This is my app.yaml which runs the node app on it's own service

runtime: nodejs10
service: servicename

handlers:
  - url: /api/.*
    secure: always
    redirect_http_response_code: 301
    script: auto

My node app has one file: nodemailer.js

app.listen(3000, () => {
    console.log("The server started on port 3000");
});

app.post("/api/sendmail", (req, res) => {
    console.log("Got Request");
}

Please let me know if anyone needs more info. Please check if you see something wrong.

I am seeing that you're using SSR in your Angular app. I think you need to modify your server.ts file. Please check below code for an example:
