Disallow new require (no-new-require)
require function is used to include modules that exist in separate files, such as:
var appHeader = require('app-header');
Some modules return a constructor which can potentially lead to code such as:
var appHeader = new require('app-header');
Unfortunately, this introduces a high potential for confusion since the code author likely meant to write:
var appHeader = new (require('app-header'));
For this reason, it is usually best to disallow this particular expression.
This rule aims to eliminate use of the
new require expression.
Examples of incorrect code for this rule:
/*eslint no-new-require: "error"*/ var appHeader = new require('app-header');
Examples of correct code for this rule:
/*eslint no-new-require: "error"*/ var AppHeader = require('app-header'); var appHeader = new AppHeader();
When Not To Use It
If you are using a custom implementation of
require and your code will never be used in projects where a standard
require (CommonJS, Node.js, AMD) is expected, you can safely turn this rule off.
This rule was introduced in ESLint 0.6.0.
