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 🙏

@prequest/miniprogram-addon

小程序附加包.提供了上传和下载文件的封装,可以与 @prequest/miniprogram 共享全局配置、全局中间件等功能。

安装

npm install @prequest/miniprogram-addon

基本使用

下载

import { createDownload } from '@prequest/miniprogram-addon'

// 传入原生方法。这样可以适配各个小程序平台
const prequest = createDownload(wx.downloadFile, { baseURL: 'http://localhost:3000' })

prequest('/audio/123', { headers: { token: '123' } }).then(res => {
  if (res.statusCode === 200) {
    console.log('下载成功')
  }
})

// 或者使用时指定URL
prequest('http://localhost:3000/audio/123').then(res => {
  if (res.statusCode === 200) {
    console.log('下载成功')
  }
})

上传

import { createUpload } from '@prequest/miniprogram-addon'

// 传入原生方法。这样可以适配各个小程序平台
const prequest = createUpload(wx.uploadFile, { baseURL: 'http://localhost:3000' })

prequest('/audio/123', { header: { token: '123' } }).then(res => {
  if (res.statusCode === 200) {
    console.log('上传成功')
  }
})

// 或者使用时指定URL
prequest('http://localhost:3000/audio/123').then(res => {
  if (res.statusCode === 200) {
    console.log('上传成功')
  }
})

配置

miniprogramminiprogram-addon 共用一份全局配置,这意味着你配置到 PreQuest 的全局配置和全局中间件都是共用的。

import { PreQuest, create } from '@prequest/miniprogram'
import { createUpload } from '@prequest/miniprogram-addon'

PreQuest.defaults.baseURL = 'http://localhost:3000'

PreQuest.use(async (ctx, next) => {
  console.log(ctx.request)

  await next()

  console.log(ctx.response)
})

const prequest = create(wx.request)
const wxUpload = createUpload(wx.uploadFile)
const wxDownload = createUpload(wx.DownloadFile)

prequest('/api')

wxUpload('/upload')

wxDownload('/download')

请求配置项

上传、请求配置项一致

| Option Name | Type | Default | Required | Meaning | Example | | ------------------------ | ------------------------------------------ | ------- | -------- | -------------- | --------------------------------- | | path | string | none | Y | 接口地址 | /audio/123 | | baseURL | string | none | N | 服务端地址 | 'http://localhost:3000' | | url | string | none | N | 服务端接口地址 | 'http://localhost:3000/audio/123' | | getNativeRequestInstance | (value: Promise<NativeInstance>) => void | none | N | 获取原生请求 | | | cancelToken | CancelToken | none | N | 取消请求 | | | header | object | none | N | 请求头 | { token: 'aaaaa'} |


此外,你也可以添加一些原生 API 支持的配置项,这部分配置项将会直接传递到原生 API 方法中。

示例:

declare module '@prequest/types' {
  interface PQRequest {
    name?: string
    filePath?: string
    formData?: Common
    timeout?: number
  }

  interface PQResponse {
    header: any
    cookies: string[]
    profile: any
  }
}

const instance = createDownload(wx.downloadFile, {
  baseURL: 'http://localhost:3000'
  name: 'filename' // You can get intelliSense here
})

// You can get intelliSense here
instance.use(async (ctx, next) => {
  ctx.request.name
  await next()
})

兼容

小程序中使用 async/await 需要安装 [email protected],框架包一般会内置这个依赖,如果没有,请自行安装,使用方式请在对应论坛进行查找。此外,由于包都是 ES6 版本的,在某些手机上可能有兼容性问题,你可以查阅这里编译代码
