Uni-app is a framework that allows developers to create cross-platform applications using Vue.js. To use WebSocket in a Uni-app project, you can follow these steps:
1. Install the `uni-socket.io` package by running the following command in your project directory:
```
npm install uni-socket.io
```
2. Import and configure the WebSocket in your component or page:
```javascript
import io from 'uni-socket.io';
export default {
data() {
return {
socket: null,
};
},
mounted() {
this.socket = io('your-socket-server-url'); // Replace with your WebSocket server URL
// Listen to events from the server
this.socket.on('connect', () => {
console.log('Connected to the WebSocket server');
});
this.socket.on('message', (data) => {
console.log('Received message:', data);
});
// Send a message to the server
this.socket.emit('message', 'Hello server');
},
beforeDestroy() {
// Close the WebSocket connection when the component is destroyed
if (this.socket) {
this.socket.close();
}
},
};
```
3. Replace `'your-socket-server-url'` with the actual URL of your WebSocket server.
4. You can then use `this.socket.emit()` to send messages to the server and `this.socket.on()` to listen to events from the server.
Remember to replace `'your-socket-server-url'` with the actual URL of your WebSocket server.
