Node.js res.send is not a function

Question

I\'m trying the following code but it\'s giving me an error, \"res.send is not a function\". Please help me.

Here\'s the code:

var http = require(\'         


        

Answer 1

Swap req & res : function(req, res)

Answer 2

According to the API reference, the first param always contain request req, then response res.

So change first param res to req:

app.get('/', function(req, res) {
    res.send("Rendering file")
}

It should fix it.

Answer 3

You can change your mind in some cases and could be write like this. note: by default, when you run node server on your local machine. Your host will always be localhost:"your desire port" Thank you!

const express = require("express")
const app = express();
const port = 8888;
// for redering hello you don't need to require fs
const fs = require("fs")

app.get ('/', (req, res) => {
    res.send("hello world")
})


app.listen(port, () => console.log(`Listening on ${port}`))

Answer 4

you should use req argument first and res as the second argument this will work without any issue

app.get('/', function(req, res) {
 res.send("Rendering file")
}

Answer 5

You've got the res and req parameters the wrong way around.

app.get('/', function(res, req)

should be

app.get('/', function(req, res)
