If you are working with Angular 4, 5, or a newer version, you will need to use the JavaScript version of Pusher and integrate it into your project. Here is a straightforward example to help you get started:
1. Begin by installing Pusher in your Angular project:
npm install --save pusher-js
2. Next, open the .angular-cli.json file and add the following line to the "scripts" section:
"scripts": ["../node_modules/pusher-js/dist/web/pusher.min.js"]
3. To make this integration work, you'll need to make an HTTP request to your server. You can achieve this by creating a service using the Angular CLI or your preferred method:
ng g s my-service
- Important:
- Don't forget to register this service in app.module.ts. Additionally, ensure you have imported HttpClientModule or HttpModule, as one of them will be used in your service.
5. Within my-service.service.ts:
- Once you have imported the httpClient module, include the following statement to start using Pusher:
declare const Pusher: any;
6. Inside the constructor of My Service:
this.pusher = new Pusher('YOUR_PUSHER_KEY', {
cluster: 'YOUR_PUSHER_CLUSTER',
encrypted: true
});
this.channel = this.pusher.subscribe('my-channel');
7. Create a function within the service to send a POST request to your server and trigger the event.
8. Once your service is set up, navigate to the component where you want the real-time functionality. First, inject your service in the constructor, and then bind to the channel for the specific event (in this case, "my-event"):
ngOnInit() {
this.myService.channel.bind('my-event', data => {
this.message = data.message;
});
}
By following these steps, you can create a simple real-time application within your Angular 5 project!
