Build

React-Native bridge static library for WeChat SDK which requires:

iOS SDK 1.7.2
Android SDK 221

And react-native-wechat has the following tracking data in open source world:

type	badge
NPM
Dependency
Downloads

Link with RNPM:

run rnpm link react-native-wechat

Add the following libraries to your "Link Binary with Libraries":

SystemConfiguration.framework
CoreTelephony.framework
libsqlite3.0
libc++
libz

And you're all set!

Manual Linking Steps

Before using this library to work with your app, you should follow the below steps to link this library with your app project, if there is something that not working, please check the list here.

Linking iOS

Link RCTWeChat library from your node_modules/react-native-wechat/ios folder like react-native's Linking Libraries iOS Guidance, Note: Don't forget to add it to "Build Phases" of your target project.

Add the following libraries to your "Link Binary with Libraries":

SystemConfiguration.framework
CoreTelephony.framework
libsqlite3.0
libc++
libz

Add "URL Schema" as your app id for "URL type" in Targets > info, See the following screenshot for the view on your XCode
Only for iOS 9, add wechat and weixin into LSApplicationQueriesSchemes in Targets > info > Custom iOS Target Properties.

Code the following in AppDelegate.m of your project to enable [LinkingIOS]

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
  return [RCTLinkingManager application:application openURL:url
                            sourceApplication:sourceApplication annotation:annotation];
}

Linking Android with Gradle

Add following lines into android/settings.gradle

include ':RCTWeChat'
project(':RCTWeChat').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-wechat/android')

Add following lines into your android/app/build.gradle in section dependencies

dependencies {
  compile project(':RCTWeChat')    // Add this line only.
}

Add following lines into MainActivity.java

import com.theweflex.react.WeChatPackage;       // Add this line before public class MainActivity
...

/**
 * A list of packages used by the app. If the app uses additional views
 * or modules besides the default ones, add more packages here.
 */
@Override
protected List<ReactPackage> getPackages() {
  return Arrays.<ReactPackage>asList(
    new MainReactPackage(), 
    new WeChatPackage()        // Add this line
  );
}

Create a package named 'wxapi' in your application package and a class named 'WXEntryActivity' in it. This is needed to get request and response from wechat.

package your.package.wxapi;

import android.app.Activity;
import android.os.Bundle;
import com.theweflex.react.WeChatModule;

public class WXEntryActivity extends Activity{
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    WeChatModule.handleIntent(getIntent());
    finish();
  }
}

Add activity declare in your AndroidManifest.xml

<manifest>
  <application>
    <!-- 微信Activity -->
    <activity
      android:name=".wxapi.WXEntryActivity"
      android:label="@string/app_name"
      android:exported="true"
      />
  </application>
</manifest>

Add these lines to 'proguard-rules.pro':

-keep class com.tencent.mm.sdk.** {
   *;
}

These example code need 'react-native-chat' and 'react-native-fs' plugin.

import * as WeChat from 'react-native-wechat';
import fs from 'react-native-fs';
let resolveAssetSource = require('resolveAssetSource');

// Code example to share text message:
try {
  let result = await WeChat.shareToTimeline({
    type: 'text', 
    description: 'hello, wechat'
  });
  console.log('share text message to time line successful:', result);
} catch (e) {
  console.error('share text message to time line failed with:', e);
}

// Code example to share image url:
// Share raw http(s) image from web will always fail with unknown reason, please use image file or image resource instead
try {
  let result = await WeChat.shareToTimeline({
    type: 'imageUrl',
    title: 'web image',
    description: 'share web image to time line',
    mediaTagName: 'email signature',
    messageAction: undefined,
    messageExt: undefined,
    imageUrl: 'http://www.ncloud.hk/email-signature-262x100.png'
  });
  console.log('share image url to time line successful:', result);
} catch (e) {
  console.log('share image url to time line failed with:', e);
}

// Code example to share image file:
try {
  let rootPath = fs.DocumentDirectoryPath;
  let savePath = rootPath + '/email-signature-262x100.png';
  console.log(savePath);
  
  /*
   * savePath on iOS may be:

   **/
  await fs.downloadFile('http://www.ncloud.hk/email-signature-262x100.png', savePath);
  let result = await WeChat.shareToTimeline({
    type: 'imageFile',
    title: 'image file download from network',
    description: 'share image file to time line',
    mediaTagName: 'email signature',
    messageAction: undefined,
    messageExt: undefined,
    imageUrl: "file://" + savePath // require the prefix on both iOS and Android platform
  });
  console.log('share image file to time line successful:', result);
} catch (e) {
  console.error('share image file to time line failed with:', e);
}

// Code example to share image resource:

  let result = await WeChat.shareToTimeline({
    type: 'imageResource',
    title: 'resource image',

  });
  console.log('share resource image to time line successful', result);
}
catch (e) {
  console.error('share resource image to time line failed', e);
}

// Code example to download an word file from web, then share it to WeChat session
// only support to share to session but time line
// iOS code use DocumentDirectoryPath
try {
  let rootPath = fs.DocumentDirectoryPath;
  let fileName = 'signature_method.doc';
  /*
   * savePath on iOS may be:
   *  /var/mobile/Containers/Data/Application/B1308E13-35F1-41AB-A20D-3117BE8EE8FE/Documents/signature_method.doc
   **/ 
  let savePath = rootPath + '/' + fileName;

  await fs.downloadFile('https://open.weixin.qq.com/zh_CN/htmledition/res/assets/signature_method.doc', savePath);
  let result = await WeChat.shareToSession({
    type: 'file',
    title: fileName, // WeChat app treat title as file name
    description: 'share word file to chat session',
    mediaTagName: 'word file',
    messageAction: undefined,
    messageExt: undefined,
    filePath: savePath,
    fileExtension: '.doc'
  });
  console.log('share word file to chat session successful', result);
} catch (e) {
  console.error('share word file to chat session failed', e);
}

//android code use ExternalDirectoryPath
try {
  let rootPath = fs.ExternalDirectoryPath;
  let fileName = 'signature_method.doc';
  /*
   * savePath on Android may be:
   *  /storage/emulated/0/Android/data/com.wechatsample/files/signature_method.doc
   **/
  let savePath = rootPath + '/' + fileName;
  await fs.downloadFile('https://open.weixin.qq.com/zh_CN/htmledition/res/assets/signature_method.doc', savePath);
  let result = await WeChat.shareToSession({
    type: 'file',
    title: fileName, // WeChat app treat title as file name
    description: 'share word file to chat session',
    mediaTagName: 'word file',
    messageAction: undefined,
    messageExt: undefined,
    filePath: savePath,
    fileExtension: '.doc'
  });
  console.log('share word file to chat session successful', result);
}
catch (e) {
  console.error('share word file to chat session failed', e);
}

shareToSession(data)

Similar to shareToTimeline but send message to a friend or a groups.

addListener(eventType, listener[, context])
