Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

modeljs-validate

一个 modeljs 模型验证插件,基于 async-validator 验证规则,为 modeljs 提供简单方便的模型属性验证 API,让数据验证更简单!✌️

Install

npm install modeljs-validator --save

Usage

定义模型 User.js

modeljs-validator 基于 async-validator开发,更多验证规则相关配置请参考 async-validator

import Model from 'modeljs-core'
import Validator from 'modeljs-validator'

// 【关键代码】安装插件
Model.use(Validator)

// 定义模型
const User = Model.define('User', {
  id: {
    type: Number,
    default: 0,
    // 【关键代码】需要在模型属性定义上加上 rules 验证规则字段
    rules: { type: 'number', required: true, message: 'id 的类型必须是数字!' }
  },
  username: {
    type: String,
    default: '',
    // 【关键代码】同一个模型属性支持多个验证规则
    rules: [
      { type: 'string', required: true, message: '用户名不能为空!' },
      { pattern: /^[a-zA-Z0-9]{4,16}$/, message: '用户名只能为4-16位字母和数字组成!' }
    ]
  },
  password: {
    type: String,
    default: '',
    rules: [
      { type: 'string', required: true, message: '密码不能为空!' },
      { min: 6, max: 18, message: '密码不能少于6位且不能大于18位!' }
    ]
  },
  sex: {
    type: Number,
    default: 0,
    rules: { type: 'enum', enum: [0, 1, 2], required: true, message: '请选择性别!' }
  }
})
常规验证
import User from './User'

// 实例化模型
var user = new User({
    id: 'myid',
    username: 'my',
    password: '',
    sex: 100
})

// 【关键代码】调用 model.validate 验证模型
user.validate().then(() => {
    console.log('验证成功')
}).catch((errors) => {
    console.log('验证失败', errors)
    /*
        errors:  
        [ { message: 'id 的类型必须是数字!', field: 'id' },
          { message: '用户名只能由4-16位字母或数字组成!', field: 'username' },
          { message: '密码不能为空!', field: 'password' },
          { message: '请选择性别!', field: 'sex' } ]
     */

    // 验证失败后可根据场景使用合适的方式将 message 展示给用户
    let err = errors.shift()
    if (err) alert(err.message)
})
选择性验证

比如在用户登录场景下只需要验证用户名和密码即可

// 【关键代码】只验证用户名、密码
user.validate(['username', 'password']).then(() => {
    console.log('验证成功')
}).catch((errors) => {
    console.log('验证失败', errors)
    /*
        errors:  
        [ { message: '用户名只能由4-16位字母或数字组成!', field: 'username' },
          { message: '密码不能为空!', field: 'password' } ]
     */

    // 验证失败后可根据场景使用合适的方式将 message 展示给用户
    let err = errors.shift()
    if (err) alert(err.message)
})

API


/**
 * 验证
 * @param  {Array} [filters]    指定需要验证的字段(默认为所以字段都会验证)
 * @param  {Promise}            验证结果 promise
 */
model.validate(filters)
