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 🙏

Readme

uni-app-fetch v0.0.1

uni-app uni.request 网络请求的扩展,支持 Promise、拦截器和 TypeScript。

安装

npm install uni-app-fetch --save

使用说明

1. 创建实例

新建 utils/uni-fetch.ts 文件,参照如下代码创建实例

import { createUniFetch } from 'uni-app-fetch'
// Typescript 相关
interface responseData {
  code: number
  message: string
  data: any
}

// #ifdef VUE2
import Vue from 'vue'
declare module 'vue/types/vue' {
  interface Vue {
    fetch: typeof uniFetch
  }
}
// #endif

// #ifdef VUE3
declare module 'vue' {
  interface ComponentCustomProperties {
    fetch: typeof uniFetch
  }
}
// #endif

// 使用自定义选项创建实例
const uniFetch = createUniFetch<responseData>({
  loading: { title: 'loading...' },
  baseURL: 'https://your.host.com',
  intercept: {
    // 请求拦截器
    request(options) {},
    // 响应拦截器
    response(result) {},
  },
})
// 模块导出
export default uniFetch

2. 应用实例

  • 模块方式(适用 Vue2 和 Vue3)
<script>
   // 导入实例模块
   import uniFetch from '@/utils/uni-fetch'
  export default {
     data() {},
     async onLoad() {
       // 用法1
       const res1 = await uniFetch<{ list: string[] }>({
         url: '/echo',
         data: {}
       })
       // 用法2
       const res2 = await uniFetch.get<{ list: string[] }>('/echo', {})
     }
   }
</script>
  • Vue 实例方式(适用于 Vue2 和配置式 Vue3)
////////// Vue2 //////////
import Vue from 'vue'
import App from './App.vue'
import './uni.promisify.adaptor'
import uniFetch from './utils/uni-fetch'

// 挂到Vue实例中
Vue.prototype.fetch = uniFetch

Vue.config.productionTip = false
const app = new (
  typeof App === 'function'
    ? App
    : Vue.extend(Object.assign({ mpType: 'app' }, App))
)()
app.$mount()

////////// Vue3 //////////
import { createSSRApp } from 'vue'
import App from './App.vue'
import uniFetch from './utils/uni-fetch'

export function createApp() {
  const app = createSSRApp(App)
  // 挂到Vue实例中
  app.config.globalProperties.fetch = uniFetch
  return { app }
}

到组件中通过 Vue 实例进行调用:

<script>
  export default {
    data() {},
    async onLoad() {
      // 用法1
      const res1 = await this.fetch<{ list: string[] }>({
        url: '/echo',
        data: {}
      })
      // 用法2
      const res2 = await this.fetch.get<{ list: string[] }>('/echo', {})
    }
  }
</script>

快捷方法

// GET 方法请求
uniFetch.fetch.get<T>(url, data?)

// POST 方法请求
uniFetch.post<T>(url, data?)

// PUT 方法请求
uniFetch.put<T>(url, data?)

// DELETE 方法请求
uniFetch.delete<T>(url, data?)
