I'm writing some code for Node.js and I'm currently using JSHint to check over my code. However, when I use the require function to import modules, it says:

'require' is not defined.

How can I suppress the warning?

"use strict";
var express = require('express');   
var register = require('./routes/register');

    try putting /*global require*/ to the file that you don't want to see, this worked for me – cubbuk Dec 12 '14 at 07:28

jshint is not aware of node.js globals by default you need to inform it.

add this comment to the top:

/* jshint node: true */

  • /*jshint node: true, bitwise:true, curly:true, forin:true, noarg:true, noempty:true, nonew:true, undef:true, strict:true, browser:true, node:true, asi:false , vars:true, es5: true, evil: true, nomen: true */ – somesh Apr 09 '13 at 06:05
  • I check it with jshint.com, it complained about `vars` as an options, try `/*jshint node: true, bitwise:true, curly:true, forin:true, noarg:true, noempty:true, nonew:true, undef:true, strict:true, browser:true, node:true, asi:false, es5: true, evil: true, nomen: true */` – generalhenry Apr 09 '13 at 06:09
  • Just to clarify, the comment should be added to the top of the *.js* file. – jlukanta Jul 06 '16 at 19:00

We can set node as the global environment variable in JSHint's .jshintrc file

This option defines globals available when your code is running inside of the Node runtime environment. Node.js is a server-side JavaScript environment that uses an asynchronous event-driven model. This option also skips some warnings that make sense in the browser environments but don't make sense in Node such as file-level use strict pragmas and console.log statements.

For more info http://jshint.com/docs/options/#node

{
   "node": true
}

Errors like 'require' is not defined, 'console' is not defined, 'module' is not defined won't show up any more

You can configure JSHint by adding "require" to the .jshintrc file. For instance:

{
    "globals" : {
        "require": false
    }
}

Or you can define globals per specific file only by:

/* global require */

For more information about how to configure JSHint please read JSHint Documentation

I stumbled upon this answer and couldn't get anything to work in VSCode. I got this to work:

  1. Open JSON Settings file using the Preferences: Open Settings (JSON) via the Command Palette Window (Ctrl-Shift-P).

  2. Add this section into the settings.json file:

    { "jshint.options": { "esversion": 8, // This gets rid of some other warnings "node": true } }
