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 🙏

Build Status

Build Setup

项目基于rollup 进行打包,具体请参考:

  • https://rollupjs.org/
  • https://github.com/rollup/rollup-starter-lib
# install dependencies
npm install

# serve with hot reload at localhost:80
npm run dev

# build for production with minification
npm run build

package entry

为了方便IDE对包的解析,也为了减少打包工具(如webpack)在引入、打包过程中产生的冗余代码,我们在package.json 里定义了多个入口。 这里是参考文档:https://github.com/rollup/rollup/wiki/pkg.module

{
    "main": "lib/index.cjs.js",
    "module": "lib/index.es.js"
}

How to use

Install

方式1:npm install

npm install nov-wechat 

0.2.6 注意:由于微信JSSDK 更新和废弃了部分接口,组件内部将抹平这部分差异。 https://mp.weixin.qq.com/wiki?t=resource/res_main&id=mp1421141115

import {initWechatShare, getUserInfo, getOpenid} from 'nov-wechat'

initWechatShare({
    title: '嘿,这里是标题',
    desc: '狗年吉祥!',
    link: 'vs.lenovo.com.cn',
    success: function() {
        console.log('用户确认分享后执行的回调函数')
    },
    cancel: function() {
        console.log('用户取消分享后执行的回调函数')
    }
})

// ....

let openid = getOpenid()
if (openid) {
    // do something ...
}

let userInfoStr = getUserInfo()
if(userInfoStr) {
    let userInfo = JSON.parse(userInfoStr)
    console.log('nickname is:' + userInfo.nickname)
    // do something ...
}
// 针对SPA 项目
let hash = sessionStorage.getItem('nov-url-hash')
if (hash) {
    // 以Vue router 举栗子 push `/user/222`
    this.$router.push(hash.substr(1))
    sessionStorage.removeItem('nov-url-hash')
}

方式2:script 引入

<script src="https://unpkg.com/nov-wechat@latest/lib/nov.min.js"></script>
<script>
nov.initWechatShare({
    title: '分享的题目'
})

var openid = nov.getOpenid()
if (openid) {
    // do something ...
}

var userInfoStr = nov.getUserInfo()
if(userInfoStr) {
    var userInfo = JSON.parse(userInfoStr)
    console.log('nickname is:' + userInfo.nickname)
    // do something ...
}
</script>

API

initWechatShare initWechatJSSDK 均做了Promise 处理,除了必要的请求,无需担心重复加载微信SDK脚本问题。

initWechatShare

Promise<Object wx> initWechatShare function (options)
  • options 参数内容
    • title 标题
    • imgUrl 分享图片(旧版参数:image)
    • desc 分享描述(旧版参数:description)
    • link 分享链接
    • type 分享类型,music、video或link,不填默认为link
    • dataUrl 如果type是music或video,则要提供数据链接,默认为空
    • success 分享成功回调
    • cancel 取消分享回调
  • jsApiList 额外的权限(可选)

设置微信分享,为方便使用做的封装,仅注册了微信JSSDK的updateTimelineShareData updateAppMessageShareData (微信JSSDK 1.4.0 更新内容)两个权限。 如果需要更多能力,请使用initWechatJSSDK 得到wx 对象后自行处理。

同一个url仅需调用一次,对于变化url的SPA的web app可在每次url变化时进行调用。

initWechatShare({
    title: '嘿,这里是标题',
    desc: '狗年吉祥!',
    link: 'vs.lenovo.com.cn',
    success: function() {
        console.log('用户确认分享后执行的回调函数')
    },
    cancel: function() {
        console.log('用户取消分享后执行的回调函数')
    }
})

initWechatJSSDK

Promise<Object wx> initWechatJSSDK function({jsApiList = config.jsApiList, debugFlag = false})

设置指定的微信 JSSDK 权限,将在updateTimelineShareData updateAppMessageShareData 之上追加,Promise resolve 时,相当于wx.ready

同一个url仅需调用一次,对于变化url的SPA的web app可在每次url变化时进行调用。 更多信息请参考微信JSSDK文档:https://mp.weixin.qq.com/wiki?t=resource/res_main&id=mp1421141115

initWechatJSSDK({
    jsApiList: ['chooseImage']
}).then(wx => {
    wx.chooseImage({
        // do something ...
    });
}).catch(function(error) {
    // handle error ...
})

getOpenid

String getOpenid function()

如果是在微信环境下,静默授权,分别从URL里or cookie 里尝试获取openid。

需要注意的是,用户首次Auth 会发生页面跳转,此刻返回值可能为null,需要在代码里判断返回值的可用性。

在跳离页面前,会将location.hash 存入 SessionStorage,key 等于 nov-url-hash

getUserInfo

String getUserInfo function()

非静默授权,用于获取用户基本信息(即便是未关注的用户)。

需要注意的是,用户首次Auth 会发生页面跳转,此刻返回值可能为null,需要在代码里判断返回值的可用性。

在跳离页面前,会将location.hash 存入 SessionStorage,key 等于 nov-url-hash

响应数据如下:

{
    "city": "朝阳",
    "province": "北京",
    "sex": 1,
    "openid": "oLHCTjvtz056e3h8Qj-xxxxxx",
    "privilege": [],
    "country": "中国",
    "unionid": "oo6-IuNNZNK148L3TL9xxxxxxx",
    "headimgurl": "http://wx.qlogo.cn/mmopen/vi_32/xxxx/132",
    "nickname": "xxxx",
    "language": "zh_CN"
}

setDmp

Void setDmp function(Boolean dmpStatus)

让网关在Auth 认证过程中增加dmp 需要的cookie,在调用getOpenid getUserInfo 之前使用。

其他需要注意的地方

  • 如果项目页面被iframe 引用,获取openid 时会导致页面白屏
  • 网关不支持带hash 的跳转,SPA下需要做处理,避免前端路由失效
  • 目前网关只支持*.lenovo.com.cn 需要检测并给提示
  • 已经添加针对iOS 下页面未加载完全时的跳转,会造成iconfont 失效的处理

在线测试

由于需要工作在lenovo.com.cn 域名下,请配置host

# example
115.28.154.221			ayouvi.lenovo.com.cn

配置后访问进行测试:
