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 🙏

steamer-plugin-mock

快速添加本地 mock 假数据命令。可以用于模拟后台接口进行测试。本项目的服务器是基于 JSON-Server 进行搭建。与服务器相关的路由、转发相关,可参考 JSON-Server 的文档。

NPM Version Travis Deps Coverage

安装

npm i -g steamerjs

npm i -g steamer-plugin-mock

使用

steamer mock

此插件会为您在项目中自动生成 mock 目录并在此目录生成一个默认的 db.js 文件。然后运行 JSON-Server7000 端口上。 您之后可以修改db.js来完成您自己的mock需求。

效果如图:

在 steamer 脚手架中使用

如果你想在 steamer 系列脚手架中使用,steamer-plugin-mock 的功能,可以设置 config/steamer.config.js"api-port": 7000 的端口。此外,脚手架默认转发至 /api/ 路径,因此 steamer-plugin-mock 需要配置 --route 参数,详细可参考后面相关的文档。

路由说明

JSON-Server 服务器根据传入的Object或者JSON文件的key作为API资源路径,值则作为返回的结果。 JSON-Server 服务器完全支持RESTful的路由,如

  • 获取第一个用户
GET /users/1
  • 分页
GET /users?_pages=7
  • 筛选
GET /users?id=2
  • 排序
GET /users?_sort=id&_order=asc

参数说明

--config

steamer mock --config xxx.js/xxx.json

此插件会使用--config参数所指定的文件运行json-server。

  • 注意:如果使用js文件,您必须export一个Object对象。

--port

steamer mock --port 8888

使用指定端口运行json-server

--route

steamer mock --route route.json

使用指定自定义配置来自定URL,比如当您遇到一下场景

  1. 真正想访问的接口资源url是api/xxx,需要转发到JSON-Server
  2. 想通过/posts/:category的方式访问博客文章的不同类别

您可以如下配置:

  • 示例文件
{
  "/api/*": "/$1",
  "/posts/:category": "/posts?category=:category"
}

效果如下

/api/posts # → /posts
/api/posts/1  # → /posts/1
/posts/javascript # → /posts?category=javascript

使用js生成假数据

如果你想用强大的js快速生成一些假数据,可以借助下面两个推荐库的能力。

  • Faker 是用于快速生成假数据的库,包括常用的头像、邮箱、电话号码等信息,推荐使用。
  • Mock 同样是生成随机数据的库,并且能生成常用的随机汉字。

下面以 Faker 作为例子,介绍如何生成用户列表数据:

const faker = require('faker');
module.exports = () => {
    let data = {
        users: [],
        foo: [],
        bar: [],
    };
    // For more usage of faker.js, please visit http://marak.github.io/faker.js/
    for(let id = 0; id < 50; id++) {
        data.users.push({
            id: id,
            firstName: faker.name.firstName(),
            lastName: faker.name.lastName(),
            email: faker.internet.email(),
            phoneNumber: faker.phone.phoneNumber(),
            avatar: faker.internet.avatar()
        })
    }
    return data;
}

以上js文件通过steamer mock --config example.js运行后,使用HTTP协议GET localhost:6800/users,即可获得50个随机生成的用户信息组成的数组:

[
  {
    "id": 0,
    "firstName": "Micheal",
    "lastName": "McKenzie",
    "email": "[email protected]",
    "phoneNumber": "837-316-7833",
    "avatar": "https://s3.amazonaws.com/uifaces/faces/twitter/poormini/128.jpg"
  },
  ...
]

可以使用RESTful的语法操作数据:

GET localhost:6800/users/2 获取第二个用户

{
  "id": 2,
  "firstName": "Devante",
  "lastName": "Crooks",
  "email": "[email protected]",
  "phoneNumber": "(108) 724-7222 x5486",
  "avatar": "https://s3.amazonaws.com/uifaces/faces/twitter/silv3rgvn/128.jpg"
}

DELETE localhost:6800/users/3 删除第三个用户
