no-new-require

不允许 new 接线员调用 require

require 函数用于包含存在于不同文件中的模块，例如：

🌐 The require function is used to include modules that exist in separate files, such as:

var appHeader = require('app-header');
1

一些模块返回一个构造函数，这可能会导致如下代码：

🌐 Some modules return a constructor which can potentially lead to code such as:

var appHeader = new require('app-header');
1

不幸的是，这很容易引起混淆，因为代码作者可能打算这样写：

🌐 Unfortunately, this introduces a high potential for confusion since the code author likely meant to write:

var appHeader = new (require('app-header'));
1

出于这个原因，通常最好禁止这种特定的表达方式。

🌐 For this reason, it is usually best to disallow this particular expression.

何时不使用

🌐 When Not To Use It

如果你使用的是 require 的自定义实现，并且你的代码永远不会在期望标准 require（CommonJS、Node.js、AMD）的项目中使用，那么你可以安全地关闭此规则。

🌐 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.

版本

此规则是在 ESLint v0.6.0 中引入。
