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-parameter

当前插件 egg-parameter 是 egg.js 框架的官方插件 egg-validate 的同构版本,如无特别需要,建议使用官方插件(egg-validate)。

比较

官方插件 egg-validate 不支持自定义返回错误响应体,只能返回 parameter 库校验后返回的错误内容,缺少灵活性,并且与笔者的实际业务需要的参数相悖,这是笔者重新开发这个插件的初衷。在使用层面上,当前插件兼容 egg-validate 的所有调用方式,同时在此基础上,增加了一些功能和扩展。

安装

$ npm i egg-parameter

配置

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

使用

实际上,当前插件做的工作只是将 parameter 做了一层封装,挂载到了 app 和 ctx 上(你查看当前插件的源码后就可以发现这一点),所有的 API 均来源于 parameter。下面介绍基础使用方式,其他 API 建议直接查看 parameter 文档。

// 定义校验规则
const rule = {
  name: 'string',
  age: 'int',
  gender: ['male', 'female', 'unknow'],
}

// 在控制器中校验
ctx.validate(rule, ctx.requesy.body)
