在 Firebase Cloud Functions 中使用 express 和 consign 进行路由

Question

I want to implement routing in my Express app which is to be exposed through a cloud function.

Here is my functions/index.js file:

const functions = require('firebase-functions');
const express = require('express');
const consign = require('consign');

const app = express();

  consign()
    .include("./routes")
    .into(app);

exports.api = functions.https.onRequest(app);

This is my./routes/index.js file

module.exports = app => {
    app.get('/', (req,res)=>{
    res.json({status:"success"});
})
}

So I guess this code is enough to host a cloud function and when I call this hosting url https://us-central1-appname-79516.cloudfunctions.net/api (url changed for reason of privacy) it should return response as {"status":"success":}

Instead when I call the above url it displays the error "Error: could not handle the request"

Help me how to use express and consign module in a cloud function

Answer 1

This is a bit late but still relevant I guess. So, this is what I've done:

consign({
  cwd: 'src'
})
.include("routes")
.into(app)

CWD sets the base directory, as stated on the docs:

Consign will simply use a relative path from your current working directory, however, sometimes you don't want heavily nested files included in the object chain, so you can set the cwd

In my case, src is the folder containing my firebase functions code (functions/src).

Hope it helps!
