Introducing the Fully Featured Scalable Chat App, by Ably's DevRel Team

The text discusses the development of a fully-featured and scalable chat application using Ably's Channels feature, which acts as an analogy for chat rooms. It highlights some challenges developers face when implementing complex or bespoke features in chat applications, such as storing and retrieving messages, authentication and authorization, handling complex messages, user information management, and scaling the application to handle large numbers of users. The text also outlines Ably's plan to address these challenges through a series of blog posts that will demonstrate best practices and provide code examples in GitHub. The tech stack for this chat application includes React for the frontend, Azure Functions for the backend, CosmosDB for the database, and Auth0 for authentication.
