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-route

注意:在小程序中使用npm包前,需先构建 npm

使用

使用前需要先了解微信小程序 路由 机制

跳转函数

push

push 函数会调用 wx.navigateTowx.switchTab,函数内部会判断该页面是否为 tabBar 页面,并自动调用 wx.navigateTowx.switchTab

import router from 'weapp-route'

page({
  navigateTo() {
    // 定义跳转页面的路径
    // 可以使用以下方式定义跳转页面的路径
    let pagePath = 'PagesLogs'               // 使用简写的方式(不包含最后一层) `/pages/logs/logs` => `PagesLogs`
    // pagePath = '/pages/logs/logs'         // 也可以写入具体的路径
    // pagePath = router.routes.PagesLogs // 或者使用 routes 对象的属性

    router.push(pagePath, {
        id: 1 // 路径携带的参数
      },
      (res) => {
        // 跳转成功的回调函数
        console.log('success callback', res)
      }, (err) => {
        // 跳转失败的回调函数
        console.log('fail callback', err)
      }, (res) => {
        // 跳转完成的回调函数
        console.log('complete callback', res)
      }
    )

    // 简写
    // router.push(pagePath)
  },

  switchTab() {
    // 与 navigateTo 一致的页面路径定义方式
    router.push('PagesIndex',
      null,
      (res) => {
        // 跳转成功的回调函数
        console.log('success callback', res)
      }, (err) => {
        // 跳转失败的回调函数
        console.log('fail callback', err)
      }, (res) => {
        // 跳转完成的回调函数
        console.log('complete callback', res)
      }
    )
  }
})

back

back 函数会调用 wx.navigateBack,关闭当前页面,返回上一页面或多级页面

import router from 'weapp-route'

page({
  navigateBack() {
    router.back(
      1, // 指定返回的页面数
      (res) => {
        // 跳转成功的回调函数
        console.log('success callback', res)
      }, (err) => {
        // 跳转失败的回调函数
        console.log('fail callback', err)
      }, (res) => {
        // 跳转完成的回调函数
        console.log('complete callback', res)
      }
    )

    // 简写
    // router.back()
  }
})

replace

replace 函数会调用 wx.redirectTowx.reLaunch,默认调用 wx.redirectTo,在路径参数后添加 @relaunch 标记则调用 wx.reLaunch

import router from 'weapp-route'

page({
  redirectTo() {
    // 跳转页面的路径写法与 push 函数一致
    router.replace('PagesLogs',
      null,
    (res) => {
      // 跳转成功的回调函数
      console.log('success callback', res)
    }, (err) => {
      // 跳转失败的回调函数
      console.log('fail callback', err)
    }, (res) => {
      // 跳转完成的回调函数
      console.log('complete callback', res)
    })

    // 简写
    // router.replace('/pages/logs/logs')
  },

  reLaunch() {
    router.replace(`PagesLogs@relaunch`)
  }
})

跳转路由

routes

获得项目中所有的路由信息,根据 app.json 中注册的页面自动生成

import router from 'weapp-route'

page({
  onLoad() {
    foo()
  },

  foo() {
    const routes = router.routes
    console.log(routes)
    // {
    //   PagesIndex: "/pages/index/index",
    //   PagesLogs: "/pages/logs/logs",
    //   PagesMyIndex: "/pages/my/index/index",
    // }
  }
})

route

获得当前跳转页面的路由信息

import router from 'weapp-route'

page({
  onLoad() {
    foo()
  },

  foo() {
    const route = router.route
    console.log(route)
    // {
    //   from: "pages/index/index",
    //   params: null,
    //   to: "/pages/logs/logs",
    // }
  }
})
