React Native UDP socket API for Android & iOS. It allows you to create UDP sockets, imitating Node's dgram API functionalities (check each method documentation for more information).
This module is used by Tradle.
Table of Contents
Getting started
Install the library using either Yarn:
yarn add react-native-udp
or npm:
npm install --save react-native-udp
Using React Native >= 0.60
Linking the package manually is not required anymore with Autolinking.
-
iOS Platform:
$ cd ios && pod install && cd ..
# CocoaPods on iOS needs this extra step
Using React Native < 0.60
You then need to link the native parts of the library for the platforms you are using. The easiest way to link the library is using the CLI tool by running this command from the root of your project:
$ react-native link react-native-udp
If you can't or don't want to use the CLI tool, you can also manually link the library using the instructions below (click on the arrow to show them):
Manually link the library on iOS
- In XCode, in the project navigator, right click

➜Add Files to [your project's name]
- Go to
node_modules
➜react-native-udp
and addUdpSockets.xcodeproj
- In XCode, in the project navigator, select your project. Add
libUdpSockets.a
to your project'sBuild Phases
➜Link Binary With Libraries
- Run your project (
Cmd+R

Manually link the library on Android
- Open up
android/app/src/main/java/[...]/MainApplication.java
- Add
import com.tradle.react.UdpSocketsModule;
to the imports at the top of the file - Add
new UdpSocketsModule()
to the list returned by thegetPackages()
method
- Append the following lines to
android/settings.gradle
:include ':react-native-udp' project(':react-native-udp').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-udp/android')
- Insert the following lines inside the dependencies block in
android/app/build.gradle
:compile project(':react-native-udp')
React Native Compatibility
React Native Version | Use Version |
---|---|
<=0.59.10 | <=2.7.0 |
>=0.60.0 | >=3.0.0 |
Usage
see/run index.js for a complete example, but the interface is like dgram's
import dgram from 'react-native-udp'
const socket = dgram.createSocket('udp4')
socket.bind(12345)
socket.once('listening', function() {
socket.send('Hello World!', undefined, undefined, remotePort, remoteHost, function(err) {
if (err) throw err
console.log('Message sent!')
})
})
socket.on('message', function(msg, rinfo) {
console.log('Message received', msg)
})
Debugging
To log all info emitted from the socket, add debug
option when creating the socket:
const socket = dgram.createSocket({
type: 'udp4',
debug: true,
})
