Error TypeError is not a function in Node js

0 votes

I'm getting the error while running the following code in Node.js

var assert = require('assert');
var request = require('request');
var index = require('./index');
it('verify javascript function', function(done) {
    var v2 = index.AddNumbers(5, 6);
    assert.equal(11, v2);
    done();
});

The index.js file contain the following code:

function AddNumbers(a,b){
    return a+b;
}

What am I doing wrong?

Hello @kartik,

Because of circular dependency, check if you have 2 classes that are requiring each other, remove one of them from requiring the other and the issue should be solved.

Hope it helps!!

Thank You!!

You are exporting

module.exports.redir = redir;

That means that your import

const redir = require('./index');

is the exported object. redir happens to be one of its keys. To use the function, use

const redir = require('./index').redir;

or destructure directly into redir

const { redir } = require('./index');
