Rails Server
Rails Server is the built-in web server for Ruby on Rails applications, typically using Puma, WEBrick, or other Rack-compatible servers to handle HTTP requests. It provides a development environment for running Rails apps locally, handling routing, asset compilation, and database connections. This tool is essential for testing and debugging during the development phase before deployment to production servers.
Developers should use Rails Server during local development to quickly test changes, debug issues, and preview applications without needing a full production setup. It's particularly useful for rapid prototyping, learning Rails, and ensuring code works correctly before deploying to platforms like Heroku or AWS. For production, alternatives like Puma with Nginx are recommended for better performance and scalability.
