Default Middleware

[metosin/reitit-middleware "0.5.12"]

Any Ring middleware can be used with reitit-ring, but using data-driven middleware is preferred as they are easier to manage and in many cases, yield better performance. reitit-middleware contains a set of common ring middleware, lifted into data-driven middleware.

• Parameter Handling
• Exception Handling
• Content Negotiation
• Multipart Request Handling
• Inspecting Middleware Chain

Parameters Handling

reitit.ring.middleware.parameters/parameters-middleware to capture query- and form-params. Wraps ring.middleware.params/wrap-params.

NOTE: will be factored into two parts: a query-parameters middleware and a Muuntaja format responsible for the the application/x-www-form-urlencoded body format.

Exception Handling

See Exception Handling with Ring.

Content Negotiation

See Content Negotiation.

Multipart Request Handling

Wrapper for Ring Multipart Middleware. Emits swagger :consumes definitions automatically.

Expected route data:

key	description
[:parameters :multipart]	mounts only if defined for a route.

(require '[reitit.ring.middleware.multipart :as multipart])

• multipart/multipart-middleware a preconfigured middleware for multipart handling
• multipart/create-multipart-middleware to generate with custom configuration

Inspecting Middleware Chain

reitit.ring.middleware.dev/print-request-diffs is a middleware chain transforming function. It prints a request and response diff between each middleware. To use it, add the following router option:

:reitit.middleware/transform reitit.ring.middleware.dev/print-request-diffs

Partial sample output:
