Reitit is a fast, data-driven routing library for Clojure and ClojureScript. It provides bi-directional routing, first-class route data, pluggable request/response coercion, and integrations with Ring, HTTP interceptors, Pedestal, and frontend routing.

Use cases

• define http routes for a ring-based clojure web app
• generate urls from route names (reverse routing)
• validate and coerce path and query parameters with malli or clojure.spec
• generate swagger or openapi documentation from route data
• route on the frontend in a clojurescript single-page app
• build interceptor-based http services with pedestal
• detect route conflicts at router creation time

When to choose

• you are building a web backend or API in Clojure or ClojureScript
• you want routing defined as plain data with composable route metadata
• you need bi-directional routing (path matching and URL generation)
• you want integrated request coercion and API documentation generation
• performance of route matching matters

When to avoid

• you are not working in Clojure or ClojureScript
• you need a full batteries-included web framework rather than a routing library
• you prefer middleware-free or macro-based routing styles like Compojure
• you need route guards or syntax features specific to other libraries like Bidi
