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 🙏

fetch-service-parser

说明

fetch-service-parser 是一个接口请求的工具,帮助快速定义接口,使用fetch请求规范,polyfill使用whatwg-fetch

使用

请求Table 列表

// api.js 定义接口
import { services } from 'fetch-service-parser'
const {parseRequest} = services

// 请求列表
export const List = parseRequest({
  url: "/api/list"
})

// 删除数据
export const Delete = parseRequest({
  url: "/api/delete/{{id}}",
  method: 'DELETE'
})


// React 使用
import React from 'react'
import {Table} from 'antd'
import {List, Delete} from './api.js'

export class IndexPage extends React.Component {
  state = {
    items: [
        {id: 1, name: '张三'}
    ]
  }
  
  componentDidMount () {
    List({
      pageIndex: 1,
      pageSize: 10
    }).then((items) => {
      this.setState({items})
    })
  }
  
  onDeleteRow = row => {
    Delete({id: row.id}).then(res => {
      alert('删除成功')
    })
  }
  
  renderOperation = row => {
    return <a onClick={e => this.onDeleteRow(row)}>删除</a>
  }
  
  render () {
    const {items} = this.state
    const columns = [
        {dataIndex: 'name', title: '姓名'},
        {title: '操作', render: this.renderOperation},
    ]
    return <Table rowKey={'id'} columns={columns} dataSource={list} />
  }
}

上传文件

// api.js 定义接口
import { services } from 'fetch-service-parser'
const {parseRequest} = services

export const Upload = parseRequest({
  url: "/api/upload",
  method: 'POST'
})


// React 使用
import React from 'react'
import {Upload} from './api.js'

export class IndexPage extends React.Component {  
  onFileChange = e => {
    const file = e.target.files[0]
    const formData = new FormData()
    formData.append("file", file)
    Upload(formData).then(res => {
      alert('上传成功!')
    })
  }
  
  render () {
    return <input type='file' onChange={this.onFileChange} />
  }
}

默认使用 Content-Type: application/json; charset=UTF-8, 修改headers

import {services, CONTENT_TYPES} from 'fetch-service-parser'
const {parseRequest} = services

export const Create = parseRequest({
  url: "/api/create",
  method: 'POST',
  headers: {
    'Content-Type': CONTENT_TYPES.FORM_URL
  },
})

默认使用 Content-Type: application/json; charset=UTF-8, 修改headers

import {services, CONTENT_TYPES} from 'fetch-service-parser'
const {parseRequest} = services

export const Create = parseRequest({
  url: "/api/create",
  method: 'POST',
  headers: {
    'Content-Type': CONTENT_TYPES.FORM_URL
  },
})

配置说明

interface apiOption {
  /**
   * 接口地址
    */
  url: string,

  /**
   * 是否跨域
   */
  cors?: boolean

  /**
   * debug = true 的时候, 会使用mock数据
   * mock 可以是数据,也可以是function
   * 在无接口的情况下,可以使用mock来伪造数据
   * 例如: mock: [{id: 1, name: '张三'}]
   *        或者使用函数
   *        mock: () =>  [{id: 1, name: '张三'}]
   */
  mock?: any

  /**
   * 启动debug, 为true时, 会使用mock的数据
   */
  debug?: boolean

  /**
   * method
   */
  method?: string,

  /**
   * 设置自定义header
   */
  headers?: any,

  /**
   * 是否不触发错误事件
   */
  noErrorTip?: boolean,

  /**
   * 是否使用请求队列, useQueue 设置为true后,该请求会进入到队列中,顺次请求
   */
  useQueue?: boolean,

  /**
   * 请求结果处理函数, 接口请求成功后,如果有该函数,会进入该函数处理结束后,返回值为接口请求拿到的值
   * 例如: parseResponse = res => {
   *        if (res.success) {
   *          return res.body  
   *        } else {
   *           throw res.message
   *        }
   *   }
   */
  parseResponse?: any,

  /**
   * 请求参数处理函数, 接口请求前,对参数进行处理
   * 例如:校验参数
   * parseParam: params => {
   *  if (!params.name) {
   *      throw '姓名不能为空'
   *  }
   *  
   *  return params
   * }
   */
  parseParam?: any,
}

事件说明

import {services} from 'fetch-service-parser'

  services.on('error', (err) => {
    // 捕获 !== 200 状态的响应
    // 捕获 parseResponse 中的 throw
    // 捕获 parseParam 中的 throw
    // 设置 noErrorTip = true 后不会触发该事件
  })

  services.on('willRequest', (apiOption) => {
    // 请求前的处理, 能拿到接口的定义
    // 通常用于全局loading显示
    // 比如
    if (apiOption.loading) {
      Loading.show()
    }
  })

  services.on('requested', (apiOption) => {
    // 请求后的处理,不管是成功或者失败都会触发,能拿到接口的定义
    // 通常用于全局loading的隐藏
    if (apiOption.loading) {
      Loading.hide()
    }
  })
