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 🙏

安装

npm i weapp-request-hook

注意:在小程序中使用npm包前,需先构建 npm

使用

Request Hook 提供以下函数

lock

添加、解除、追加请求锁 lock unlock addLock

import requestHook from 'weapp-request-hook'

const [testHook] = requestHook.init('test')

Page({
  data: {
    flag: false
  },

  foo() {
    // 在锁定期间,foo 函数将无法再次执行
    testHook.lock(() => {
      setTimeout(() => {
        testHook.unlock() // 2秒后解除内置锁
      }, 2000)
    })
  }

  bar() {
    testHook.addLock(this.data.flag) // 添加自定义锁,当满足锁条件时,lock 的回调函数将不会执行
    testHook.lock(() => {
      setTimeout(() => {
        testHook.unlock() // 2秒后解除内置锁以及自定义锁
      }, 2000)
    })
  }
})

loading

打开、关闭加载交互 loading unloading

import requestHook from 'weapp-request-hook'

const [testHook] = requestHook.init('test')

Page({
  data: {
  },

  foo() {
    testHook.lock(() => {
      testHook.loading()

      setTimeout(() => {
        testHook.unloading()
        testHook.unlock()
      }, 2000)
    })
  }

  bar() {
    testHook.lock(() => {
      // 完整配置
      testHook.loading({
        type: 2 // 加载类型  1 => wx.showLoading 2 => wx.showNavigationBarLoading 3 => wx.startPullDownRefresh
        title: '', // type 为 1 时生效,提示的内容
        mask: true, // type 为 1 时生效,是否显示透明蒙层,防止触摸穿透
        success: () => {}, // 加载交互接口调用成功的回调函数
        fail: () => {}, // 加载交互接口调用失败的回调函数
        complete: () => {} // 加载交互接口调用结束的回调函数(调用成功、失败都会执行)
      })

      setTimeout(() => {
        testHook.unloading({
          noConflict: false, // 目前 toast 和 loading 相关接口可以相互混用,此参数可用于取消混用特性
          success: () => {}, // 加载交互接口调用成功的回调函数
          fail: () => {}, // 加载交互接口调用失败的回调函数
          complete: () => {} // 加载交互接口调用结束的回调函数(调用成功、失败都会执行)
        })
        testHook.unlock()
      }, 2000)
    })
  }
})

success

请求成功事件 success

import requestHook from 'weapp-request-hook'

const [testHook] = requestHook.init('test')

Page({
  data: {
  },

  foo() {
    testHook.lock(() => {
      testHook.loading()

      setTimeout(() => {
        // 调用 success 函数后,无需调用 unloading 以及 unlock
        testHook.success(() => {
          // 请求成功后的回调
        })
      }, 2000)
    })
  }
})

fail

请求失败事件 fail

import requestHook from 'weapp-request-hook'

const [testHook] = requestHook.init('test')

Page({
  data: {
  },

  foo() {
    testHook.lock(() => {
      testHook.loading()

      setTimeout(() => {
        // 调用 fail 函数后,无需调用 unloading 以及 unlock
        testHook.fail(() => {
          // 请求失败后的回调
        }, {
          // 可传入 Toast 配置,与 wx.showToast 一致的配置项
        })
      }, 2000)
    })
  }
})

page

用于分页请求,可自动管理分页数

import requestHook from 'weapp-request-hook'

const [testHook] = requestHook.init('test')

Page({
  data: {
  },

  foo() {
    testHook.lock(async () => {
      testHook.loading()

      await api({
        page: testHook.page // 1
      })

      testHook.unloading()
      testHook.unlock()
    }, 1) // 可在 lock 函数中设置 page 值,默认为 1
  },

  onReachBottom() {
    testHook.lock(async() => {
      testHook.loading()

      await api({
        page: testHook.page // 2
      })

      testHook.unloading()
      testHook.unlock()
    }, testHook.page + 1)
  },
})

最佳实践

// index.ts
import requestHook from 'weapp-request-hook'

// 首页需要请求两个接口的数据(热门商品、普通商品)
const [hotGoodsHook, goodsHook] = requestHook.init('hotGoods', 'goods')

Page({
  data: {
    hotGoods: [] as any[]

    goods: [] as any[],
    last: false
  },

  onLoad() {
    this.fetchHotGoodsData()

    this.fetchGoodsData()
  },

  // 页面上拉触底事件的处理函数
  onReachBottom() {
    goodsHook.addLock(this.data.last) // 追加锁,如果已无更多数据,则无需请求接口
    goodsHook.lock(async() => {
      goodsHook.loading()

      // 分页请求更多的商品数据
      await api({
        page: goodsHook.page
      })

      goodsHook.unloading()
      goodsHook.unlock()
    }, goodsHook.page + 1) // 传入分页数
  },

  fetchHotGoodsData() {
    hotGoodsHook.lock(async() => {
      hotGoodsHook.loading()

      // 发起 GET 请求
      await ...

      hotGoodsHook.unloading()
      hotGoodsHook.unlock()
    })
  },

  fetchGoodsData() {
    goodsHook.lock(async() => {
      goodsHook.loading({
        type: 2 // 使用 showNavigationBarLoading
      })

      // 发起 GET 请求
      await ...

      goodsHook.unloading()
      goodsHook.unlock()
    })
  }

  submitForm() {
    const [formHook] = requestHook.init('form')

    formHook.lock(async() => {
      formHook.loading()

      // 发起 POST 请求
      const res = await ...

      if (res) {
        formHook.success(() => {
          console.log('提交成功')
        })
      } else {
        formHook.fail(() => {
          console.log('提交失败')
        })
      }
    })
  }
})
