  1. Path string

  2. Verb. One of :any, :get, :put, :post, :delete, :patch, :options, :head

  3. Handler or vector of interceptors

  4. (Optional) Route name clause

  5. (Optional) Constraint clause

Syntax for table-routes

(ns myapp.service
  (:require [io.pedestal.http.route.definition.table :as table]))

(def application-routes
    {:host "" :scheme :https}
    [["/user"          :get user-search-form]
     ["/user/:user-id" :get view-user        :constraints {:user-id #"[0-9]+"}]

Syntax for expand-routes

(ns myapp.service
  (:require [io.pedestal.http.route :as route]))

(def application-routes
    #{{:host "" :scheme :https}
      ["/user"          :get user-search-form]
      ["/user/:user-id" :get view-user        :constraints {:user-id #"[0-9]+"}]

Detailed Reference

Path string

The path string must:

  • Start with a slash ("/")

  • Consist of zero or more path segments separated by slashes.

Each path segment is one of:

  1. A string literal

  2. A colon (":") followed by a legal Clojure identifier name. This is a path parameter.

  3. An asterisk ("*") followed by a legal Clojure identifier name. This is a wildcard path.

When routing a request, a path parameter will match any characters other than a slash. The matched string will be bound to the request by the path parameter name from the route.

For example, using the route /users/:id/orders/:order-id, the following request URLs would be treated as:

URL Match? Path params





{:id "abcdef" :order-id "12345"}



{:id "123545" :order-id "From Strings"}

All path parameter values are strings.


The verb must be one of the keywords in #{:any, :get, :put, :post, :delete, :patch, :options, :head}.

:any is a wildcard verb. During request routing, :any will match all requests.

Handler or Interceptors

The "handler position" be anything that satisfies the IntoInterceptor protocol. This includes:

  • Function value

  • Symbol

  • Var

  • Map

  • List

Route Name Clause

A route name clause is the keyword :route-name followed by a keyword. Route names must be unique.

Constraint Clause

A constraint clause is the keyword :constraints followed by a map.
