node.js和mongodb连接问题

Question

I am building a website using node.js and mongoDB backend. Whenever I start running the server, frontend works completely fine but I am unable to connect to my database. Running mongod command always gives the message

{"t":{"$date":"2020-11-10T10:46:27.043+5:30"},"s:"I","c":"Network","id":23016,
"ctx":"listener","msg":"Waiting for connection","attr":{"port":27017,"ssl":"off"}}

I simultaneously executed npm start from the frontend and backend folders. The npm start from the backend folder gives

[nodemon] starting `node ./server.js`
Listening on port 8080
MongoDB connected

The npm start from the frontend folder gives

App running at:
- Local: http://localhost:8080/
- Network: http://192.168.56.1:8080/

But whenever the open it, it gives

Cannot GET /

Is it because I couldn't connect to the database? I'm fairly new to this. I can't seem to understand the reason behind this. Can anyone please help me out?

Answer 1

Cannot GET /

means http://localhost:8080/ has no method defined in your app. if you are using expressJs in your server.js add

var express = require('express')
var app = express()

    app.get('/', function (req, res) {
      res.send('No More error')
})

Here we are saying: send "No More error" whenever user opens "/" path.

ie http://localhost:8080/ in your case.
