To structure a Rails 7 application with Hotwire, you use Turbo Frames and Turbo Streams to deliver real-time page updates without writing JavaScript. The approach leverages RESTful routing and server-rendered HTML to synchronize changes instantly across connected clients.

The best way to optimize Active Record queries involves applying conventions like eager loading associations to prevent N+1 problems, selecting only needed columns, and using service objects to encapsulate complex data retrieval logic cleanly outside of controllers.

You set up Sidekiq for background processing in Rails 7 by creating worker classes and queuing jobs outside the main request cycle. This handles heavy tasks asynchronously, improving application responsiveness and scalability.

Yes, Action Cable works directly with Turbo Streams to broadcast real-time updates in Rails. Action Cable transmits server-side changes over WebSockets, and Turbo Streams dynamically morph the DOM on connected clients to reflect new state immediately.

For testing Rails 7 applications with RSpec, you should follow patterns utilizing factories for test data, model specs for validations, and system specs for end-to-end browser interactions. This ensures robust coverage for Active Record models and Hotwire integrations.

Use Turbo Frames when you need to isolate specific sections of a page for independent navigation and updates, and use Turbo Streams when you need to broadcast real-time changes to multiple clients via Action Cable for broader page synchronization.
