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 🙏

简介

wec-tools 是基于koa2kou-router开发的工具类,目前包含验证器模块(WecValidator),用于API参数校验

快速开始

  npm install wec-tools

使用说明

校验器(WecValidator)使用方法

校验器基于validator.js做校验

validator.js

  import {WecValidator, WecRule, WecException} from 'wec-tools'

  class PositiveIntegerValidator extends WecValidator {
  constructor() {
    super()

    // 属性校验器
    this.id = [
      new WecRule('isInt', 'id需要为正整数', {
        min: 1
      })
    ]
  }

  // 自定义校验器
  validatePassword(vals) {
    const pass1 = vals.password1
    const pass2 = vals.password2

    if (pass1 !== pass2) {
      throw new Error('两个密码必须相同')
    } else {
      return true
    }
  }
}
注意
  • 自定义属性需要写在构造函数中,且必须为数组,数组的每一项必须为 WecRule 实例对象
  • 自定义方法必须以 validate 开头,接收一个参数对象,为所有API请求传入的所有参数(包括header、path、query及body中的参数)

router.js

  import {PositiveIntegerValidator} from './validators/validate.js'

  const params = await new PositiveIntegerValidator().validate(ctx)

Tips

  • 校验成功会返回API请求的所有参数,在parmas中
  • 校验失败会自动抛出 WecException 异常
  • 修改lCalender插件, 位于src目录下
