Package Exports

react-native-wss

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (react-native-wss) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

React native WebSocket Secure

Every project what i created has problem with securing websockets. So, I decide to share my codes with everyone, and i hope this will be merged into react native one day. This library allows you to set wss address in WebSocket with ca (plain cert), pfx (base64) and passphrase.

Installing

Download the react-native-wss repository & go to the folder

git clone https://github.com/Lipo11/react-native-wss.git
cd react-native-wss

Copy scripts/postinstall.js and patches/node_modules.zip into your project root

cp -r ./{scripts,patches} project/

Install yauzl library to devDependencies

npm i project/ --save-dev yauzl

Add postinstall into project package.json scripts object

"scripts": {
  "postinstall": "node scripts/postinstall.js"
}

Compile android native code with wss support

This step can be skipped ( I compile the newest react native version with WSS into patches/ )

#Clone repository from github.
git clone https://github.com/facebook/react-native.git
#Checkout to your version of react native into cloned react native repository folder.
git checkout 0.61-stable

# Now, You have to replace a file
# ReactAndroid/src/main/java/com/facebook/react/modules/websocket/WebSocketModule.java
# with (into react native repository folder)
# scripts/ReactAndroid/src/main/java/com/facebook/react/modules/websocket/WebSocketModule.java
cp scripts/ReactAndroid/ nativeReact/ReactAndroid/

# Let's build android native project( be sure NDK is installed and path is defined into bash_brofile )
# When you can see the following error "ndk-build binary cannot be found" you can just open the project in the Android Studio and set the NDK path in File > Project Structure > SDK Location
# Run this into react native repository folder
npm i
./gradlew clean
./gradlew assembleRelease

# After the react native was builded with success, rename the file
# ReactAndroid/build/outputs/aar/ReactAndroid-release.aar
# to your project react native version ( for example 0.61.5 )
# ReactAndroid/build/outputs/aar/react-native-0.61.5.aar
mv ReactAndroid/build/outputs/aar/ReactAndroid-release.aar ReactAndroid/build/outputs/aar/react-native-0.61.5.aar

# and copy it into your project root with path
# patches/android/com/facebook/react/react-native/0.61.5/react-native-0.61.5.aar
mkdir -p project/patches/android/com/facebook/react/react-native/0.61.5/
cp nativeReact/ReactAndroid/build/outputs/aar/react-native-0.61.5.aar project/patches/android/com/facebook/react/react-native/0.61.5/

# The last step is zip the folder patches/android/ with name of your react native project version ( for example 0.61.5 )
zip -r -X 0.61.5.zip project/patches/android

Run the postinstall

npm i
# or
node scripts/postinstall.js

API

Now, you can use wss address with certificates. ( No need to import any other libs. )

this._ws = new WebSocket( 'wss://192.168.0.1', [],
{
  headers: { Authorization: 'Bearer 123' },
  ca: '-----BEGIN CERTIFICATE-----\n\n-----END CERTIFICATE-----\n',
  pfx: 'base64==',
  passphrase: 'mustbedefinedforpfx'
});
