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 🙏

完整的用例与参数说明

示例代码

const { Mocker } = require('@jarryui/mocker');
const Koa = require('koa');

const mocker = new Mocker({
  prefix: '/api'
});

mocker.mock({
  path: '/demo',
  mock: {
    'list|10': [
      {
        'id|+1': 1,
        'name|+1': ['foo', 'bar', 'baz']
      }
    ]
  }
});

const app = new Koa();

app.use(mocker.routes());
app.listen(3000);

使用 node 运行上述 js 代码,并访问 http://localhost:3000/api/demo 即可查看效果

构造函数参数说明

|参数名|类型|默认值|必填|说明| |:-|:-:|:-:|:-:|:-| |prefix|string|空字符串|否|该实例所有mock接口前缀|

mock() 参数说明

mocker.mock() 方法可以创建一个 mock 接口,以下是参数说明:

|参数名|类型|默认值|必填|说明| |:-|:-:|:-:|:-:|:-| |path|string||是|mock 接口路径| |method|string|get|是|mock 接口的HTTP方法,不区分大小写| |mock|Object 或 Function||是|mock 接口内容定义,或提供一个返回 Mock 定义的回调函数,具体格式请参照 Mock.js 语法规范| |middlewares|Array<Function>|[]|否|Koa 中间件数组,数组内的所有中间件仅对path参数指定的路径生效|

其他用例

使用回调定义接口

mocker.mock({
  path: '/demo/:name',
  mock(ctx) {
    return {
      "message": `hello, ${ctx.params.name}`
    }
  }
});
// http://localhost:3000/api/demo/bob

{
  "message": "hello, bob"
}

使用中间件

mocker.mock({
  path: '/demo',
  mock: {
    "list|2": [{
      "id|+1": 1
    }]
  },
  middlewares: [
    async function(ctx, next) {
      await next();
      ctx.set('Access-Control-Allow-Origin', '*');
    }
  ]
});
// Access-Control-Allow-Origin: *
// http://localhost:3000/api/demo

{
  "list": [
    {
      "id": 1
    },
    {
      "id": 2
    }
  ]
}

从目录中导入接口定义

  • /index.js
const { Mocker } = require('@jarryui/mocker');
const Koa = require('koa');
const path = require('path');

const mocker = new Mocker({
  prefix: '/api'
});

mocker.loadDir(path.join(process.cwd(), 'mocks'));

const app = new Koa();

app.use(mocker.routes());
app.listen(3000);
  • /mocks/demo.js
module.exports = {
  path: '/demo',
  mock: {
    message: 'Hello World'
  }
}
  • 浏览器
// http://localhost:3000/api/demo

{
  "message": "Hello World"
}
  • loadDir 参数说明
