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

React-Native-Wechat-Lib

[React Native] bridging library that integrates WeChat SDKs:

  • [x] iOS SDK 1.8.7.1
  • [x] Android SDK 5.5.6

前言

首先向各位声明,本库是在 react-native-wechat 基础上进行重写。

本库已经向 react-native-wechat 提交合并请求#526,但由于 react-native-wechat 所使用的 WeChat SDK 已经是几年前的版本,新 SDK 接口变动大,我修改的代码相当多,几乎重构了核心部分,导致合并需要耗费不小时间,再加上需要兼容正在使用旧版 SDK 的开发者,事情变得异常艰辛。

考虑到自身使用和其它开发者的需要,最终决定开一个新仓库,提供给新项目使用。

最后,感谢 yorkie 和各位开发者为 react-native-wechat 做出的贡献。

附言

如果你的 IOS 应用需要使用不带支付功能的 WeChat SDK,请使用带有 “-notpay” 后缀的 NPM 包。
If you need to use the WeChat SDK without payment for your IOS version, use the NPM package with the suffix "-notpay".

目录

安装

npm install react-native-wechat-new --save
react-native link react-native-wechat-new

起步

API文档

本库支持 TypeScript,使用 Promiseasync/await 来接收返回。

接口名称和参数尽量跟腾讯官网保持一致性,除了嵌套对象变成扁平对象,你可以直接查看腾讯文档来获得更多帮助。
