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 🙏

express-kv-api

express插件:key-value 形式,简单模拟api,结合 mockjs 更灵活。最简单的后端请求模拟方式,可用于前端本地测试。

Installation

npm install express-kv-api --save-dev

Usage

Server

for express


const bodyParser = require('body-parser')
const kvApi = require('express-kv-api')
const express = require('express')

const path = require('path')
const process = require('process')

const app = express()

app.use(bodyParser.urlencoded({ extended: false }))
app.use(bodyParser.json())
app.use(kvApi({
  // 接口文件夹路径,默认为项目下的`server`文件,支持 json/js 文件
  dirPath: path.join(process.cwd(), 'server'),
  // 是否监听接口文件夹内变动,默认true
  watch: true,
  // 数据处理函数,可用于统一的数据包装,默认直接返回data
  dataWrap (data) {
    return {
      success: true,
      data: data,
      message: '请求成功',
    }
  },
  // 返回对象用于「函数」类型value,以下为默认方式
  reqDataWrap (req, params) {
    return {
      params,
      ...req.params,
      ...req.query,
      ...req.body
    }
  },
  // 以目录结构划分模块
  moduleByPath: false,
  // 请求的默认方法,默认为all
  defaultMathod: 'post'
}))

app.listen(8080)
...

for webpack-dev-server

const bodyParser = require('body-parser')
const kvApi = require('express-kv-api')

const config = {
  ...,
  after (app) {
    app.use(bodyParser.urlencoded({ extended: false }))
    app.use(bodyParser.json())
    app.use(kvApi())
  }
}

for @vue/cli-service

const bodyParser = require('body-parser')
const kvApi = require('express-kv-api')

const config = {
  ...,
  devServer: {
    ...,
    after (app) {
      app.use(bodyParser.urlencoded({ extended: false }))
      app.use(bodyParser.json())
      app.use(kvApi())
    }
  }
}

for [email protected]

const config = {
  ...,
  beforeDevServer (app) {
    app.use(kvApi())
  }
}

API

接口文件,可获取到请求参数,做简单逻辑处理。 请求地址按express格式, 返回数据按mock语法规范。 书写示范:

module.exports = {
  /**
   * 指明method为post,默认为all
   * 延迟1000ms请求返回
   */
  'post|1000 /api/add': true,
  /**
   * function形式,将参数传入
   * {
   *  params:[],
   *  ...req.query,
   *  ...req.body,
   * }
   */
  '/api/service/(getAll|getList)' (data) {
    return {
      type: data.params[0],
      id: data.id,
      'child|2-8': [
        {
          'id|+1': data.id * 100,
          name: 'test3',
        }
      ]
    }
  },
}
