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 🙏

egg-ecarx-validate

增加default属性,在参数不存在、为空字符串时默认参数值
增加参数过滤功能,过滤无关参数,只提取rule里有的参数,实现对参数整体的约束
增加返回值:validate应当只负责校验,不应该对原始对象进行修改,所以校验后产生了 赋值/过滤 的结果 通过返回值返回

Install

$ npm i egg-ecarx-validate --save

Usage

// {app_root}/config/plugin.js
exports.validate = {
  enable: true,
  package: 'egg-ecarx-validate',
};

Configuration

// {app_root}/config/config.default.js
exports.validate = {
};

Example

//ctx.request.body = {other: '无关参数',str: ""}
let rule = {
  //参数是否选填由 required 配置决定,默认是true
  //字符串类型参数 为 "" 时、其他类型参数选填但且未填时,可由default配置默认值
  num: {type: 'string', required: false, default: 'abc'},
  time: {type: 'number', default: Date.now()},
  str: {type: 'string', default: undefined} //赋值undefined等同删除
}

let data = ctx.validate(rule)
或 let data = ctx.validate(rule,ctx.request.body)
data: {num: 'abc', time: 152332312312,other: '无关参数'}

let data = ctx.validate(rule,true)
或 let data = ctx.validate(rule,ctx.request.body, true)
data: {num: 'abc', time: 152332312312}
