19rails

19rails is an open-source web application framework designed to simplify the development of scalable, data-driven web applications. It is built around a modular architecture organized into 19 distinct rails, each representing a cross-cutting concern such as routing, data persistence, business logic, presentation, authentication, and messaging. The project emphasizes clarity of separation between responsibilities while enabling cohesive orchestration through its core runtime.

Design and architecture: The 19-rail model divides application concerns into separate, interoperable layers. A central router delegates requests to controllers, which coordinate with a rich set of services and a pluggable ORM for data access. The framework ships with templating for server-rendered views, a client-side hydration approach, an API layer, and a background job system. A plugin mechanism allows adding rails without altering core code.

Development and ecosystem: 19rails is primarily written in JavaScript and TypeScript, with a language-agnostic API surface to facilitate bindings from other runtimes. It emphasizes convention with opt-out customization, comprehensive testing tools, and built-in security patterns. The project maintains a modular package structure and a registry of optional rails that developers can enable as needed.

Reception and use: As a relatively new entrant relative to established frameworks, 19rails has an active but smaller community. It is popular among teams seeking a high degree of modularity and explicit cross-cutting concerns in large or evolving codebases. Typical use cases include enterprise web applications, dashboards, and RESTful or real-time services.
