TypeError: io is not a function

[zeeshanjan82]

When trying to connect using

    this._socket = io('http://localhost:5000');

I get the error TypeError: io is not a function. I can see the socket.io/socket.io.js file in the network tab and is getting loaded. I have installed socket.io using npm socket.io and am using socket.io-client version 1.3.6

This looks really a basic error and it's more likely something wrong with your settings. Feel free to reopen.

Same problem here using Parcel.js / Typescript as the ES6 bundler

[renatosvo]

import * as io from 'socket.io-client';
solves the problem.

[TheMaverickProgrammer]

What if were using plain old JavaScript?

[Kacppian]

Use io.connect() instead of io().

[rishat5081]

io.connect() can't solve the problem, issue is still there

[Tzahile]

for me the combination of @renatosvo and @Kacppian suggestions worked:
import * as io from "socket.io-client";
let ioClient = io.connect();

const express = require('express');
const router = express.Router();
var app = express();
const io = require('socket.io');
const fs = require('fs');

const { ensureAuthenticated } = require('../db/auth.js');


//exporting dashboard 
module.exports = {
  dash: router.get('/', (req,res)=>{
    var chat = io.on('connection', (socket)=>{
      console.log('chat is connected');
    })
    res.render('dashboard', {chat:chat});

  })
