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 🙏

🦅 一个基于 nodeexpress 的 轻量级 Mock 套件 命令行工具

简介

内置 Static ServerMock ServerSPA Web Server、Http?s request proxy 等功能集。

简易轻量B/S 架构0 秒启动的本地命令行 Mock 服务套件, 支持热更新,对于开发调试 mock 数据很实用,能提高前端开发者的开发效率。支持 GET,POST,PUT,DELETE,PATCH,OPTIONS,COPY,LINK,UNLINK,PURGE 等常用请求类型,无需布署后端,可能是本地最好用的 Mock 工具之一。

特性功能:

  • 支持统计 mock 的文件数量和 mock 请求数量
  • 支持终端打开 mock 文件的所在位置

Static Server (和 Mock Server 互斥使用)

简易的静态资源服务器,可用于开发调试,如需更多使用场景,请选择 http-server

Mock Server - 本地 Mock 服务器

Mock File 仅支持 commonjs 规范的 js、cjs 文件,不支持 ES Module

支持以下常见业务场景:

  • [x] 无服务端演示项目的数据 Mock
  • [x] 业务开发接口联调前的数据 Mock
  • [x] 保留业务项目的所有或部分接口的响应数据(写入文件)
  • [x] 保障前端开发调试不受后端服务影响(当后端服务挂掉或部分接口响应异常时启用 Mock)

Web Server - SPA Web 服务器

对 React、Vue 等单页应用项目构建生成的 dist 目录,启动本地 web 服务器(相当于使用本地安装的 nginx 服务)来模拟运行生产环境下的 web 服务

Http request proxy - 基于浏览器的本地代理服务

实现了本地接口代理的能力,一般接口测试工具无法查看到 request 和 response 中 headers 的更多详情,这里实现了接口代理功能,在 Network 中可查看接口调用的详细信息。

两种应用场景

  • 项目 dev 模式下的接口代理请求
  • Chrome 的 Console 执行 fetch 请求(用于接口测试)

Installation:

Running on-demand:

Using npx you can run the script without installing it first:

npx mock-service-cli [path] [options]

Globally via npm

npm install --global mock-service-cli

This will install mock-service-cli globally so that it may be run from the command line anywhere.

Globally via Homebrew

brew install mock-service-cli

As a dependency in your npm package:

npm install mock-service-cli

Usage:

 mock-service-cli [options] [path]

[path] defaults to ./mock .

Examples: -O '/api/apaas\|http://192.168.0.105:60700,/api/permission\| http://192.168.0.105:60700'. Must start web server to use proxy for http request test under browser console or api test tools. | - | | -P or --web-port | Web server port to use. Use -P 9090 to look for an open port, starting at 9090 | 9090 | | -b or --web-baseurl | Specify public path of the SPA web server, can be base address of SPA route. | - | | -R or --static-server | Specify directory of the Static Web Server. | - |

Example

  1. Specify static resource file directory to startup Static Server.

mock-service-cli -R ./test

  1. Specify mock server port.

mock-service-cli -p 8085

  1. Enable cors of mock server, specify the origin and headers of http request.

mock-service-cli -o "http://192.168.0.8:38200,http://10.30.30.3" -H "custom-header"

  1. Specify mock directory to startup Mock Server.

mock-service-cli -d ./mock

  1. Specify mock file to startup Mock Server.

mock-service-cli -f ./mock/test.js

  1. Start socket server for used to save api response data.

mock-service-cli -S

  1. Only Used as api server for test on browser console or api request tools.

    must specified server directory which can be empty but not includes index.html file, and also need config API proxy.

mock-service-cli -D server -O '/api/apaas|http://192.168.0.105:60700'

  1. Start static web server for SPA, and optionally specify public path and port.

mock-service-cli -D ../react-best-practice/dist [-b '/redbridge/'] [-P 9090]

  1. Enable Proxy base on above item 7. support accept js file、json file、cli arguments string

    • cli arguments string

      mock-service-cli -D ./ -O '/api/apaas|http://192.168.0.105:60700,/api/permission|http://192.168.0.105:60700'

    • js file

      mock-service-cli -D ./ -O ./proxy.js

      proxy.js file content as follows:

module.exports = {
  '/api/apaas': 'http://192.168.0.105:60700',
  '/api/permission': 'http://192.168.0.105:60700'
};

编写 Mock 文件

mock 请求的类型支持GET,POST,PUT,DELETE,PATCH,OPTIONS,COPY,LINK,UNLINK,PURGE

如果 ./mock/test.js 的内容如下,

module.exports = {
  // GET 可忽略
  '/mock/mock/api/test': { aa: 1, bb: '默认GET请求' },
  'GET /mock/api/:id/test': { aa: 1, bb: '使用id占位符' },
  'GET /mock/api/test1': { aa: 1, bb: '指定GET 方法' },
  'POST /mock/api/test': { aa: 1, bb: 'POST 方法' },
  'DELETE /mock/api/test': { aa: 1, bb: 'DELETE 方法' },
  'PUT /mock/api/test': { aa: 1, bb: 'PUT 方法' },
  'PATCH /mock/api/test': { aa: 1, bb: 'PATCH 方法' },
  'OPTIONS /mock/api/test': { aa: 1, bb: 'OPTIONS 方法' },
  'COPY /mock/api/test': { aa: 1, bb: 'COPY 方法' },
  'LINK /mock/api/test': { aa: 1, bb: 'LINK 方法' },
  'UNLINK /mock/api/test': { aa: 1, bb: 'UNLINK 方法' },
  'PURGE /mock/api/test': { aa: 1, bb: 'PURGE 方法' },
  // 支持自定义函数,API 参考 express@4
  '/mock/api/video/test': (req, res) => {
    // 添加特定请求头token
    res.header('token', '5848778333359208');
    res.json({ aa: 1, bb: 'asdf' });
  }
};

然后访问 本地代理地址 + /mock/api/222/test (例如http://127.0.0.1:8090/mock/api/222/test) 就能得到 { aa: 1, bb: '使用 id 占位符' } 的响应,其他以此类推。

Mock Server

引入 Mock.js

Mock.js 是常用的辅助生成模拟数据的三方库,借助他可以提升我们的 mock 数据能力。

比如:

const mockjs = require('mockjs');

module.exports = {
  // 使用 mockjs 等三方库
  'GET /api/tags': mockjs.mock({
    'list|100': [
      {
        'NO|+1': 1,
        city: '@city',
        maintainType: '@cname(3, 5)',
        urgentType: '@cword(3, 5)',
        'isCrash|1': 'true',
        createTime: '@date',
        'value|1-100': 50,
        'type|0-2': 1
      }
    ]
  })
};

启动 Web Server, 在本地像 nginx 一样运行 dist 文件对应的 SPA

Web Server

启动 Web Server, 启用 Proxy

Web Server Proxy

借助 socket.io 保留接口数据

save-datamock-dir-stat 事件会自动生成 mock-list.json 文件(维护接口<url, [method]>的关系映射),方便查阅接口统计信息

// 连接SocketServer
import { io } from 'socket.io-client';

const socket = io.connect('http://{MockServerIP}:{PORT}/mock-data', {
  transports: ['websocket'],
  path: '/ws/mock-service'
});
// 向SocketServer发消息:保存接口数据
socket.emit('save-data', { url, method, data, dir });
// 向SocketServer发消息:获取指定目录的Mock统计信息
socket.emit('mock-dir-stat', dirPath);
// 监听SocketServer消息:获取指定目录的Mock统计信息
socket.on('mock-dir-stat', function (mockDirStat) {});
// 向SocketServer发消息:获取指定文件的Mock统计信息
socket.emit('mock-file-stat', filePath);
// 监听SocketServer消息:获取指定文件的Mock统计信息
socket.on('mock-file-stat', function (mockFileStat) {});

在 axios.js 文件中完成保存所有接口响应数据、根据 Mock 数据池自动 Mock 的操作, 示例如下:

import { io } from 'socket.io-client';
import axios from 'axios';

const socket = io.connect('http://192.168.31.54:8090/mock-data', {
  transports: ['websocket'],
  path: '/ws/mock-service',
  query: {
    token: 'yyds'
  }
});

socket.emit('mock-dir-stat', '/home/chen/projects/model-ui/mock');
socket.on('mock-dir-stat', function (data) {
  console.debug('mock-dir-stat:', data);
});
// 保存所有接口响应数据(也可过滤部分接口)
axios.interceptors.response.use(res => {
  const {
    config: { method, url },
    data
  } = res;
  socket.emit('save-data', { url, method, data, dir: '/home/chen/projects/model-ui/mock' });
  return res;
});
// 根据Mock数据池自动Mock(也可根据实际场景决定是否Mock)
axios.interceptors.request.use(config => {
  if (Object.keys(mockObj).includes(`${config.method} ${config.url}`)) {
    config.baseURL = 'http://localhost:8090';
  }
  return config;
});
