  • Essential guide to WebSocket authentication
    Of course, if this all sounds like a headache, you might consider Ably. Apart from solving the authentication problem, Ably provides additional features you’d need to implement on top of WebSockets like Presence and message queues, and provides production guarantees that will be time-consuming or costly to achieve on your own like 99.999% uptime guarantee, exactly-once delivery, and guaranteed message ordering. - Source: dev.to / 6 months ago

    Ably is a robust real-time data delivery platform based on WebSockets with features like message ordering, presence, and connection recovery. Customers include Toyota, HubSpot, and Verizon. - Source: dev.to / 8 months ago

For instance, I wanted each browser's cursor position to be continually available to other... - Source: dev.to / 10 months ago
  • Laravel Realtime with Ably & Laravel Livewire
    So let's get started. Firs thing to do is to create an account in Ably, so head there and create your account. Then, you have to create an application, give it a name, and we are good to go. The next thing to do, is to grab the API key. From the Ably dashboard, head to API Keys, you will find 2 keys, we are interested in the first one. - Source: dev.to / about 1 year ago
