As a result of Rails being supplied with a Dockerfile enables Kamal to seamlessly execute the operation, transforming the utility into a container image, according to Heinemeier’s statement. With the release of Rails 8, the `ActionDispatch::Response` object has been enhanced to include a proxy, dubbed ` Rack::Sendfile`, which stands at the gateway of the Puma web server to provide X-Sendfile acceleration, asset compression, and asset caching. There’s no need to set up an Nginx server or other web servers at the front end. Additionally, Kamal 2 features a Kamal Proxy that allows for seamless interchanging of generic Traefik configurations at launch. This proxy offers rapid zero-downtime deployments, automated SSL certificate management, and support for multiple functionalities on a single server, requiring minimal configuration, in response to the Rails announcement regarding Rails 8.
In Rails 8, database-backed adapters empower the use of options similar to caching, WebSockets, and jobs. Utilizing a database-backed Motion Cable adapter eliminates the need for Redis to function as a publish-subscribe (pubsub) server, thereby seamlessly relaying WebSocket messages between appliances and diverse processes in real-time. The company offers a database-backed caching mechanism through its Lively Assist feature, eliminating the need for external solutions like Redis or Memcached to store and retrieve HTML fragments in particular. While building a database-backed Lively Job, you can now complete tasks without requiring Redis and a separate job-running framework like Sidekiq or Delayed Job, making it more accessible for many people.
Rails 8 streamlines the process by generating a comprehensive authentication system, providing a solid foundation for building session-based, password-resettable, and metadata-tracking authentications seamlessly. Rails 8 offers additional options to make the SQLite adapter and Ruby driver suitable for production-ready use. The Rails app’s default asset pipeline is replaced by the modern Webpack system, supplanting the legacy Sprockets framework that originated in 2009.
