jValidation

a simple util for better validation code semantization.

Notification: this validation is meant to focus on simple type data validation, if you want to do some Array or Object or Function type validation, you may do it before you generate a validation via this util.

API

Very Quick Start

1. run npm install --save-dev jvalidation or yarn add --save-dev jvalidation

2. import to your code

import Validation from 'jvalidation'
    // init validation
    let name = 'John'
    let _validation = new Validation(name)
    
    // run validator
    _validation.isChName('请输入纯中文汉字', 'name')

    // get result
    console.log(_validation.result, _validation.info, _validation.invalid)
    // false, '请输入纯中文汉字', [{tag: 'name', info: '请输入纯中文汉字'}]

MultiRules for Same Target

• supported chainig invocation

import Validation from 'jvalidation'

    let name = 'John'
    let _validation = new Validation(name, {assertion: false})

    _validation.isRequired().isChName().isLengthBetween(3,6,'长度不对')

    console.log(_validation.result, _validation.info, _validation.invalid)
    // false, '长度不对', [[ { tag: 'name', info: '请输入中文字符' }, { tag: 'length', info: '长度不对'}] }]

Group Validation for Different Targets

import { GroupValidation } from 'jvalidation'
    const sample = {
        userName: '我只是个测试的a',
        mobile: '136616666166',
        idCardNo: '310109198701235364X'
    }

you can use this pattern

    let _validation = new GroupValidation(
        [sample.userName, {assertion: false},
        ['isChName', '请输入纯中文', 'name'],
        ['isLengthBetween', 3, 6, '请输入3-6长的字符', 'length']],
        [sample.mobile, null, 'isMobileNo'],
        [sample.idCardNo, null, ['isIdNo', '请输入合法身份证', 'idcard']]
    )
    _validation.validate(false)

or this pattern

    let _validation = new GroupValidation(
        [sample.userName, {assertion: false},
        ['isChName', '请输入纯中文', 'name'],
        ['isLengthBetween', 3, 6, '请输入3-6长的字符', 'length']]
    )
    .compose([sample.mobile, null, 'isMobileNo'])
    .compose([sample.idCardNo, null, ['isIdNo', '请输入合法身份证', 'idcard']])
    _validation.validate(false)

or this pattern

    let _validation = new GroupValidation(
        [sample.userName, {assertion: false},
        ['isChName', '请输入纯中文', 'name'],
        ['isLengthBetween', 3, 6, '请输入3-6长的字符', 'length']],
    ).compose(
        [sample.mobile, null, 'isMobileNo'],
        [sample.idCardNo, null, ['isIdNo', '请输入合法身份证', 'idcard']]
    )
    _validation.validate(false)

to get result you may use .getInvalidInfo()

    _validation.getInvalidInfo()
    // this will return all the invalid items with tags in Object

you may also use .getInvalidTags() to get all the invalid tags you input in an Array

    _validation.getInvalidTags()

Assertion

• if you want to implement assertion in a single item, just set {assertion: false} as the second prop.
• if you want to implement assertion assertion mode in group validation, just use .validate() instead of .validate(false) when the group rule of validation is invoked.
