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 🙏

本地开发的数据mock中间件

使用


const http = require('http')
const mock = require('middleware-mock')
/**
mock.initCfg({
  filePath: '',
  map: {},
  callback: [],
  hooks: {}
})
*/
const server = http.createServer((req, res) => {
  mock(req, res)
});
server.listen(8000);

document

配置文件

  • 默认读取项目根目录(process.cwd())下 .mock.config.js 文件

example

const path = require('path')
module.exports = {
  // mock 文件目录, default: ./mock
  filePath: path.resolve(__dirname, 'test/mock'),
  // 接口和mock文件映射
  map: {
    // 获取绑定银行卡列表
    '/api/pay/bank-card/bind/list/get.json': './a.json'
  },
  // 配置 jsonp key default: ['callback', 'jsonpCallback']
  callback: ['xxx1', 'xxxx2'],
  hooks: {
    // 处理请求地址的钩子函数,在 map 前调用
    dealPath (path) {
      return path + '.json'
    },
    // 处理mock数据钩子函数, 在stringify 和 jsonp格式化前调用
    dealData (data) {
      data.asd = 123
      return data
    }
  }
}

mock file

支持json、json5、js, 无后缀时优先级:js > json > json5

js mock 说明

// example 1
module.exports = 'mock'
module.exports = {name: 'mock'}

// example 2 异步 promise 支持
module.exports = async function (req, res) {
  return new Promise((r) => {
    setTimeout(() => {
      r('1qqqqwqw')
    }, 200)
  })
}

// example 3 直接操作 req 和 res 对象
module.exports = function (req, res) {
  res.end('结束')
}

json mock 说明

{
  "key": "name"
}

json5 mock 说明

// 配置说明
{
  // 定义的key
  key: 'name' // 注释
}
