How do I implement subscriptions with Apollo Client?

To implement subscriptions with Apollo Client, you need to set up a WebSocket link. Have you already installed the necessary packages?

Yes, I have the Apollo Client and GraphQL packages installed. What’s next?

Great! Next, you need to create a WebSocket link using the subscriptions-transport-ws package. Do you need help with that?

Yes, can you provide a code example for creating the WebSocket link?

Sure! Here’s a basic example:

import { WebSocketLink } from 'apollo-link-ws';

const wsLink = new WebSocketLink({
  uri: 'ws://your-graphql-endpoint',
  options: {
    reconnect: true,
  },
});

This sets up a WebSocket link that reconnects automatically.
