Node浏览器JavaScript中字符串校验工具库（Node浏览器JavaScript中字符串校验工具库）

validator.js是一个Github上专门针对字符串校验所建立的一个工具库，validator.js包含了大量实用的字符串校验和清洗方法，并且支持在Node环境和浏览器环境使用，非常实用。

https://Github.com/validatorjs/validator.js

包管理方式安装

npm install validator //或者 yarn add validator

可以在各种开发场景下使用

• 不在es6环境下的模块化

var validator = require('validator'); validator.isEmail('foo@bar.com'); //=> true

• es6的模块化

可以一次性全部导入

import validator from 'validator';

也可以针对不同方法单独引入，比如我们只需要导入验证邮箱的方法

import isEmail from 'validator/lib/isEmail';

或者Tree-shakeable ES imports导入

import isEmail from 'validator/es/lib/isEmail';

• 浏览器直接使用

<script type="text/javascript" src="validator.min.js"></script> <script type="text/javascript"> validator.isEmail('foo@bar.com'); //=> true </script>

方法非常丰富，可以根据需要进行使用，建议先看一下Github上中每个方法的含义和使用方式。

validator.js是一个非常值得学习的工具库，不仅是使用它，也可以用它来学习一些JavaScript的基础知识，学习其中各类方法的写法，也可以巩固JavaScript的基础知识！
