# React-Native-Wechat-Lib

### 2021-8-7
- 升级安卓的版本库,改成maven,仅仅是为了升级版本号方便使用

[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](https://github.com/yorkie/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](https://github.com/yorkie/react-native-wechat/pull/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](https://github.com/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](#安装)
- [起步](#起步)
- [API 文档](#API文档)

## 安装

```sh
npm install react-native-wechat-lib --save
react-native link react-native-wechat-lib
```

## 起步

- [iOS 安装](./docs/build-setup-ios.md)
- [Android 安装](./docs/build-setup-android.md)

## API 文档

本库支持 `TypeScript`,使用 `Promise` 或 `async/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。
