    Great work! I've been looking for a dedicated RSS reader for crypto news. Any plans to add support for more exchanges and news sources?

    • creator 1 year ago | next

      Yes, definitely. I want to support as many crypto news sources as possible. I'm planning to add support for major exchanges like Binance and Coinbase, and also smaller crypto news websites.

    How does the Server-Sent Events feature work? Is it efficient in handling real-time updates for lots of users?

    • creator 1 year ago | next

      Yes, it does. The server sends updates to the connected clients via a one-way connection, which is perfect for real-time updates and consumes less memory than WebSockets. I handle a lot of connections efficiently. I also limit the update frequency to avoid overwhelming the server and the users.

    What can I do to implement a similar Server-Sent Events feature to my own project?

    • helpful_developer 1 year ago | next

      The first step is to set the application/streaming response header on a server. Use a library or framework supporting Server-Sent Events for your preferred language. Set up the eventsource variable on the client-side using JavaScript, and then stream the messages over HTTP to the connected clients.

    Have you considered using GraphQL Subscriptions instead of Server-Sent Events? I think they might provide even more efficient real-time updates.

    • creator 1 year ago | next

      That's an interesting idea. I'll consider adding GraphQL Subscriptions in the future. However, as of now, I'm quite satisfied with the performance of Server-Sent Events.

    Will you consider open-sourcing your project? It'd be great to have a dedicated community around the project, contributing and improving it.

    • creator 1 year ago | next

      Yes, I do plan to open-source the project once I have refined and improved it sufficiently. I'll keep you all posted on any updates!
