通过运行来通过npm安装它 

npm i @cesium133/forgjs

 示例：

onst { Validator, Rule } = require('@cesium133/forgjs');

  const emailRule = new Rule({
    type: 'email',
    user: user => user === 'dedede',
    domain: domain => ['outlook', 'gmail', 'yahoo'].indexOf(domain) !== -1,
  }, null);
  
  const passwordRule = new Rule({
    type: 'password',
    minLength: 8,
    uppercase: 1,
    numbers: 1,
    matchesOneOf: ['@', '_', '-', '.', '!'],
  }, null);

  const vComplexe = new Validator({
    age: new Rule({ type: 'int', min: 18, max: 99 }),
    dateOfBirth: new Rule({ type: 'date' }),
    array: new Rule({ type: 'array', of: new Rule({ type: 'string' }) }),
    email: emailRule
    pasword: passwordRule
  });

  vComplexe.test({
    age: 26,
    dateOfBirth: new Date(1995, 10, 3),
    array: ['1'],
    email: 'my-email@yahoo.fr;',
    password: 'ad1_A@@Axs',
  }); /// returns true

错误处理 

这样做可以获得自定义消息错误：

const vComplexe = new Validator({
    age: new Rule({
      type: 'int', min: 18, max: 99,
    }, 'age must be integer and between 18 and 99'),
    dateOfBirth: new Rule({ type: 'date' }, 'date must be a date'),
  });

  vComplexe.getErrors({
    age: 16,
    dateOfBirth: 123,
  }); // ['age must be integer and between 18 and 99', 'date must be a date']
