    • saves 1 evaluation per schema, per request, for dynamic contexts
  • Fix: Merge :{form,multipart}-params :info :public :parameters :formData field at runtime

2.0.0-alpha11 (2017-10-25)

  • dynamic-context is removed in favor of :dynamic true meta-data for contexts:
(require '[compojure.api.help :as help])

(help/help :meta :dynamic)
; :dynamic
;
; If set to to `true`, makes a `context` dynamic,
; e.g. body is evaluated on each request. NOTE:
; Vanilla Compojure has this enabled by default
; while compojure-api default to `false`, being
; much faster. For details, see:
;
; https://github.com/weavejester/compojure/issues/148
;
; (context "/static" []
;   (if (= 0 (random-int 2))
;      ;; mounting decided once
;      (GET "/ping" [] (ok "pong")))
;
; (context "/dynamic" []
;   :dynamic true
;   (if (= 0 (random-int 2))
;      ;; mounted for 50% of requests
;      (GET "/ping" [] (ok "pong")))
  • You can now include sequences of routes in routes and context:
(context "/api" []
  (for [path ["/ping" "/pong"]]
    (GET path [] (ok {:path path}))))
  • updated deps:
[metosin/ring-swagger "0.24.3"] is available but we use "0.24.2"

  • Stringify :pred under Spec :problems, fixes #345
  • Better error message if :spec coercion is tried without required dependencies
  • Don't memoize keyword-specs for now - allow easier redefining

2.0.0-alpha8 (11.10.2017)

  • Aligned with the latest spec-tools: [metosin/spec-tools "0.4.0"]

  • To use Clojure 1.9 & Spec with Swagger, these need to be imported:

[org.clojure/clojure "1.9.0-beta2"]
[metosin/spec-tools "0.4.0"]
  • Support ring.middleware.http-response exception handling directly:
(require '[compojure.api.sweet :refer :all])
(require '[ring.util.http-response :as http])

(api
  {:exceptions {:handlers {::http/response handle-thrown-http-exceptions-here}}
  (GET "/throws" []
    (http/bad-request! {:message "thrown response"})))
  • Use Muuntaja for all JSON transformations, drop direct dependency to Cheshire.
  • Muuntaja api instance (if not undefined, e.g. nil) is injected into :compojure.api.request/muuntaja for endpoints to use.
    • path-for and path-for* now use this to encode path-parameters.
(require '[compojure.api.sweet :refer :all])
(require '[compojure.api.request :as request])
(require '[muuntaja.core :as m])

(api
  (GET "/ping" {:keys [::request/muuntaja]}
    (ok {:json-string (slurp (m/encode muuntaja "application/json" [:this "is" 'JSON]))})))
  • FIXED: separate Muuntaja-instance optins are merged correctly.
(require '[compojure.api.sweet :refer :all])
(require '[ring.util.http-response :refer [ok]])
(require '[metosin.transit.dates :as transit-dates])
(require '[muuntaja.core :as m])

          merge
          {:decoder-opts {:handlers transit-dates/readers}
           :encoder-opts {:handlers transit-dates/writers}}))))

(api
  {:formats muuntaja}
  (GET "/pizza" []
    (ok {:now (org.joda.time.DateTime/now)})))
  • dropped dependencies:
[cheshire "5.7.1"]
[org.tobereplaced/lettercase "1.0.0"]
  • updated dependencies:
[potemkin "0.4.4"] is available but we use "0.4.3"
[metosin/ring-swagger "0.24.2"] is available but we use "0.24.1"
[metosin/spec-tools "0.4.0"] is available but we use "0.3.2"

2.0.0-alpha7 (31.7.2017)

  • drop direct support for application/yaml & application/msgpack. If you want to add them back, you need to manually add the dependencies below and configure Muuntaja to handle those:
(require '[muuntaja.core :as muuntaja])
(require '[muuntaja.format.yaml :as yaml-format])
(require '[muuntaja.format.msgpack :as msgpack-format])

(api
  {:formats (-> muuntaja/default-options)
                (yaml-format/with-yaml-format)
                (msgpack-format/with-msgpack-format))}
  ...)
  • dropped dependencies:
[circleci/clj-yaml "0.5.6"]
[clojure-msgpack "1.2.0"]

2.0.0-alpha6 (26.7.2017)

  • spec coericon also calls s/unform after s/conform, e.g. specs like (s/or :int spec/int? :keyword spec/keyword?) work now too.

  • updated dependencies:

[circleci/clj-yaml "0.5.6"] is available but we use "0.5.5"
[metosin/muuntaja "0.3.2"] is available but we use "0.3.1"
[ring/ring-core "1.6.2"] is available but we use "1.6.1"
[metosin/ring-swagger "0.24.1"] is available but we use "0.24.0"

1.1.11 (25.7.2017)

  • updated deps for the 1.*

  • BREAKING: in compojure.api.swagger, the swagger-ui and swagger-docs now take options map with path key instead of separate optional path & vararg opts.

    • normally you would use swagger api-options or swagger-routes and thus be unaffected of this.

  • updated dependencies:

[prismatic/plumbing "0.5.4"] is available but we use "0.5.3"
[compojure "1.6.0"] is available but we use "1.5.2"
[prismatic/schema "1.1.6"] is available but we use "1.1.3"
[ring-middleware-format "0.7.2"] is available but we use "0.7.0"
[metosin/ring-http-response "0.9.0"] is available but we use "0.8.1"
[metosin/ring-swagger "0.24.1"] is available but we use "0.22.14"

2.0.0-alpha5 (2.7.2017)

  • Spec coercion endpoints produce now Swagger2 data

  • To use Clojure 1.9 & Spec with Swagger, these need to be imported:

[org.clojure/clojure "1.9.0-alpha17"]
[metosin/spec-tools "0.3.0"]
  • To use Clojure 1.8 & Spec with Swagger, these need to be imported:
[org.clojure/clojure "1.8.0"]
[metosin/spec-tools "0.3.0" :exclusions [org.clojure/spec.alpha]]
[clojure-future-spec "1.9.0-alpha17"]
  • If the dependencies are found, the following entry should appear on log:
INFO :spec swagger generation enabled in compojure.api
  • updated deps:
[metosin/spec-tools "0.3.0"] is available but we use "0.2.2"
  • Schema coercion errors have the :schema as pr-str value.
  • resource body-params are associated over existing instead of merged. e.g. extra params are really stripped off.

2.0.0-alpha4 (19.6.2017)

  • Update to latest Muuntaja.

    • by default, allow empty input body for all formats
    • see changelog

  • updated deps:

[metosin/muuntaja "0.3.1"] is available but we use "0.2.2"

2.0.0-alpha3 (13.6.2017)

  • move compojure.api.request back to src.

2.0.0-alpha2 (13.6.2017)

  • BREAKING: Simplified pluggable coercion.
    • NO SWAGGER-DOCS YET, see https://github.com/metosin/spec-swagger
    • guide in wiki: https://github.com/metosin/compojure-api/wiki/Coercion
    • injected in request under :compojure.api.request/coercion
    • new namespace compojure.api.coercion, replacing compojure.api.coerce.
    • :coercion can be set to api, context, endpoint macros or a resource. It can be either:
      • something satisfying compojure.api.coercion.core/Coercion
      • a Keyword for looking up a predefined Coercion via compojure.api.coercion.core/named-coercion multimethod.
    • coercion is stored in Route :info
    • signature of Coercion:
(defprotocol Coercion
  (get-name [this])
  (get-apidocs [this spec data])
  (encode-error [this error])
  (coerce-request [this model value type format request])
  (coerce-response [this model value type format request]))

Predefined coercions

  • :schema (default) resolves to compojure.api.coercion.schema/SchemaCoercion
  • :spec resolves to compojure.api.coercion.spec/SpecCoercion
  • nil removes the coercion (was: nil or (constantly nil)).

Spec with resources

[metosin/spec-tools "0.2.2" :exclusions [org.clojure/spec.alpha]]
[clojure-future-spec "1.9.0-alpha17"]

  • BREAKING: Clojure 1.7.0 is no longer supported (no back-port for clojure.spec).

  • use ClassLoader -scoped Schema memoization instead of api-scoped - same for anonymous map specs

  • :body-params is available for exception handlers, fixes #306 & #313

  • BREAKING: Restructuring internal key changes in compojure.api.meta:

    • :swagger is removed in favor of :info.
    • swagger-data is pushed to [:info :public] instead of [:swagger]
    • top-level :info can contain:
      • :static-context? -> true if the context is internally optimized as static
      • :name, route name
      • :coercion, the defined coercion

2.0.0-alpha1 (30.5.2017)

  • More descriptive error messages, fixes #304 and #306:
    • when request or response validation fails, more info is provided both to exception hanlders and via default implementations to external clients:
(let [app (GET "/" []
              :return {:x String}
              (ok {:kikka 2}))]

;            :route-params {},
;            :params {},
;            :compojure/route [:get "/"]}}

  • Introduce dynamic-context that works like context before the fast context optimization (#253).

    • If you build routes dynamically inside context, they will not work as intended. If you need this, replace context with dynamic-context.
    • See issue #300.

    For example:

;; compojure-api 1.1
(context "/static" []
  (if (its-noon?)
    (GET "/noon-route" [] (ok "it's noon")))

;; compojure-api 1.2:
(dynamic-context "/static" []
  (if (its-noon?)
    (GET "/noon-route" [] (ok "it's noon")))
  • Remove restructuring migration helpers for 1.0.0 (for :parameters and :middlewares)

1.2.0-alpha8 (18.5.2017)

  • BREAKING: resource function is always 1-arity, options and info are merged.

  • resource can have :middleware on both top-level & method-level.

    • top-level mw are applied first if the resource can handle the request
    • method-level mw are applied second if the method matches
(def mw [handler value]
  (fn [request]
    (println value)

1.2.0-alpha7 (15.5.2017)

  • BREAKING: resource separates 1-arity :handler and 3-arity :async-handler. Rules:
    • if resource is called with 1-arity, :handler is used, sent via compojure.response/render
    • if resource is called with 3-arity, :async-handler is used, with fallback to :handler.
      • sent via compojure.response/send so manifold Deferred and core.async ManyToManyChannel can be returned.

1.2.0-alpha4 (23.3.2017)

  • Initial support for Async Ring, using CPS, manifold or core.async

  • compojure.api.core/ring-handler to turn a compojure-api route into a 1-arity function

    • can be passed into servers requiring handlers to be Fn

  • :params are populated correctly from :body-params

  • Allow nil paths in routing, allows easy (static) conditional routing like:

(defn app [dev-mode?]
  (api
    (GET "ping" [] (ok "pong"))
    (if dev-mode?
      (GET "/drop-the-db" [] (ok "dropped")))))
  • Support java.io.File as response type, mapping to file downloads
    • no response coercion
    • fixes #259
(GET "/file" []
  :summary "a file download"
  :return java.io.File
  :produces #{"image/png"}
  (-> (io/resource "screenshot.png")
      (io/input-stream)
      (ok)
      (header "Content-Type" "image/png"))))

  • Fix help-for for some restructure methods #275 by Nicolás Berger

  • BREAKING: in compojure.api.swagger, the swagger-ui and swagger-docs now take options map with path key instead of separate optional path & vararg opts.

    • normally you would use swagger api-options or swagger-routes and thus be unaffected of this.

  • BREAKING: middleware is removed because it dangerously applied the middleware even to requests that didn't match the contained routes. New route-middleware only applies middlewares when the request is matched against contained routes.

    • route-middleware is not exposed in sweet namespace but is available at compojure.api.core

1.2.0-alpha2 (22.1.2017)

this is an alpha release, feedback welcome

  • BREAKING: Requires Java 1.8 (as Muuntaja requires it)
  • Fix Cider indentation for route macros, by Joe Littlejohn
  • Restructuring :body does not keywordize all keys,
    • e.g. EDN & Transit keys are not transformed, JSON keys based on the JSON decoder settings (defaulting to true).
  • resource under context requires exact routing match, fixes #269
  • Endpoints can return compojure.api.routes/Routes, returned routes don't commit to swagger-docs - as they can be generated at runtime
  • BREAKING: Better request & response coercion
    • in compojure.api.middleware, the default-coercion-matchers is removed in favour of create-coercion & default-coercion-options
    • uses negotiated format information provided by Muuntaja, fixes #266
    • old custom coercion should work as before, as the contract has not changed
    • Old defaults: coerce everything (request & response body) with json-coercion-matcher
    • New defaults: see the table below:
FormatRequestResponse
application/ednvalidatevalidate
application/transit+jsonvalidatevalidate
application/transit+msgpackvalidatevalidate
application/jsonjson-coercion-matchervalidate
application/msgpackjson-coercion-matchervalidate
application/x-yamljson-coercion-matchervalidate

defaults as code:

(def default-coercion-options
  {:body {:default (constantly nil)
          :formats {"application/json" json-coercion-matcher
                    "application/msgpack" json-coercion-matcher
                    "application/x-yaml" json-coercion-matcher}}
   :string string-coercion-matcher
   :response {:default (constantly nil)
              :formats {}}})

to create a valid coercion (for api or to routes):

;; create (with defaults)
(mw/create-coercion)
(mw/create-coercion mw/default-coercion-options)

;; no response coercion
(mw/create-coercion (dissoc mw/default-coercion-options :response)

;; disable all coercion
nil
(mw/create-coercion nil)
  • Route-records printing is cleaned up

1.2.0-alpha1

  • BREAKING: use Muuntaja instead of ring-middleware-format, #255 for format negotiation, encoding and decoding.
    • 4x more throughput on 1k JSON request-response echo
    • api key :format has been deprecated (fails at api creation time), use :formats instead. It consumes either a Muuntaja instance, Muuntaja options map or nil (unmounts it). See how to configure Muuntaja how to use.
  • ~~EXPERIMENTAL~~: fast contexts, #253 - use static routes if a context doesn't do any lexical bindings
    • up to 4x faster context routing.
  • Support delayed child route resolution.
  • Removed pre 0.23.0 api option format assertions.
  • :middleware for api & api-middleware, run last just before the actual routes. Uses same syntax as with the routing macros.
(api
  {:middleware [no-cache [wrap-require-role :user]]}

(api
  {:format {:formats [custom-json-format :json :edn]}}
  ...)

1.1.5 (27.7.2016)

  • New api-options [:api :disable-api-middleware?] to disable the api-middleware completely. With this set, api only produces the (reverse) route-tree + set's swagger stuff and sets schema coercions for the api. 
(api
  {:api {:disable-api-middleware? true}
   ;; Still available
   :swagger {:ui "/api-docs"
             :spec "/swagger.json"
             :data {:info {:title "api"}}}}

  • :data in swagger-routes can be overridden even if run outside of api:
(def app
  (routes
    (swagger-routes
      {:ui "/api-docs"
       :spec "/swagger.json"
       :data {:info {:title "Kikka"}
              :paths {"/ping" {:get {:summary "ping get"}}}}})
    (GET "/ping" [] "pong"))))
  • unsetting :format option in api-middleware causes all format-middlewares not to mount
  • unsetting :exceptions option in api-middleware causes the exception handling to be disabled
  • unsetting :coercion translates to same as setting it to (constantly nil)
(api
  {:exceptions nil ;; disable exception handling
   :format nil     ;; disable ring-middleware-format
   :coercion nil}  ;; disable all schema-coercion
  ;; this will be really thrown

1.1.0 (25.4.2016)

  • BREAKING: Move compojure.api.swgger/validate to compojure.api.validator/validate.
  • BREAKING: If a resource doesn't define a handler for a given request-method or for top-level, nil is returned (instead of throwing exeption)
  • BREAKING Resource-routing is done by context. Trying to return a compojure.api.routing/Route from an endpoint like ANY will throw descriptive (runtime-)exception.
(context "/hello" []
  (resource
    {:description "hello-resource"
     :responses {200 {:schema {:message s/Str}}}

           :handler (fnk [[:query-params name]]
                      (ok {:message (format "hello, %s!" name)}))}}))
  • api-level swagger-options default to {:ui nil, :spec nil}. Setting up just the spec or ui, doesn't automatically setup the other (like previously)
  • Strip nils from :middleware, fixes #228
  • describe works with anonymous body-schemas (via ring-swagger 0.22.7), Fixes #168
  • Support compojure-api apps in Google App Engine by allowing scjsv to be excluded (uses json-schema-validator, which uses rogue threads):
[metosin/compojure-api "1.1.0" :exclusions [[metosin/scjsv]]]
  • updated dependencies:

[cheshire "5.6.1"] is available but we use "5.5.0"

1.0.2 (27.3.2016)

  • Parameter order is unreversed for fnk-style destructurings for small number of paramerers, fixes #224
  • Moved internal coercion helpers from compojure.api.meta to compojure.api.coerce.
  • New compojure.api.resource/resource (also in compojure.api.sweet) for building resource-oriented services 
(defn resource
  "Creates a nested compojure-api Route from enchanced ring-swagger operations map and options.
  By default, applies both request- and response-coercion based on those definitions.

  Options:

  - **:coercion**       A function from request->type->coercion-matcher, used
                        in resource coercion for :body, :string and :response.
                        Setting value to `(constantly nil)` disables both request- &
                        response coercion. See tests and wiki for details.

  Enchancements to ring-swagger operations map:

  1) :parameters use ring request keys (query-params, path-params, ...) instead of
  swagger-params (query, path, ...). This keeps things simple as ring keys are used in
  the handler when destructuring the request.

  2) at resource root, one can add any ring-swagger operation definitions, which will be
  available for all operations, using the following rules:

    2.1) :parameters are deep-merged into operation :parameters
    2.2) :responses are merged into operation :responses (operation can fully override them)
    2.3) all others (:produces, :consumes, :summary,...) are deep-merged by compojure-api

  3) special key `:handler` either under operations or at top-level. Value should be a
  ring-handler function, responsible for the actual request processing. Handler lookup
  order is the following: operations-level, top-level, exception.

  4) request-coercion is applied once, using deep-merged parameters for a given
  operation or resource-level if only resource-level handler is defined.

  5) response-coercion is applied once, using merged responses for a given
  operation or resource-level if only resource-level handler is defined.

  Note: Swagger operations are generated only from declared operations (:get, :post, ..),
  despite the top-level handler could process more operations.

  Example:

  (resource
    {:parameters {:query-params {:x Long}}
     :responses {500 {:schema {:reason s/Str}}}
     :get {:parameters {:query-params {:y Long}}
           :responses {200 {:schema {:total Long}}}
           :handler (fn [request]
                      (ok {:total (+ (-> request :query-params :x)
                                     (-> request :query-params :y))}))}
     :post {}
     :handler (constantly
                (internal-server-error {:reason \"not implemented\"}))})"
  ([info]
   (resource info {}))
  ([info options]
   (let [info (merge-parameters-and-responses info)
         root-info (swaggerize (root-info info))
         childs (create-childs info)
         handler (create-handler info options)]
     (routes/create nil nil root-info childs handler))))

1.0.1 (28.2.2016)

  • For response coercion, the original response is available in ex-data under :response. This can be used in logging, "what did the route try to return". Thanks to Tim Gilbert.

1.0.0-RC1 (2.2.2016)

compare

  • Move from compile-time to runtime route resolution.
    • Most of the internal macro magic has been vaporized
    • Uses internally (invokable) Records & Protocols, allowing easier integration to 3rd party libs like Liberator
      • even for large apps (100+ routes), route compilation takes now millis, instead of seconds
    • sub-routes can be created with normal functions (or values), making it easier to:
      • pass in app-level dependencies from libs like Component
      • reuse shared request-handling time parameters like path-parameters and authorization info
(defn more-routes [db version]
  (routes
    (GET "/version" []
      (ok {:version version}))
    (POST "/thingie" []
      (ok (thingie/create db)))))

Breaking changes

  • BREAKING Vanilla Compojure routes will not produce any swagger-docs (as they do not satisfy the Routing protocol. They can still be used for handling request, just without docs.

    • a new api-level option [:api :invalid-routes-fn] to declare how to handle routes not satisfying the Routing protocol. Default implementation logs invalid routes as WARNINGs.

  • BREAKING compojure.core imports are removed from compojure.api.sweet:

    • let-request, routing, wrap-routes

  • BREAKING Asterix (*) is removed from route macro & function names, as there is no reason to mix compojure-api & compojure route macros.

    • GET* => GET
    • ANY* => ANY
    • HEAD* => HEAD
    • PATCH* => PATCH
    • DELETE* => DELETE
    • OPTIONS* => OPTIONS
    • POST* => PUT
    • context* => context
    • defroutes* => defroutes

  • BREAKING swagger-docs and swagger-ui are no longer in compojure.api.sweet

    • Syntax was hairy and when configuring the spec-url it needed to be set to both in order to work
    • In future, there are multiple ways of setting the swagger stuff:
      • via api-options :swagger (has no defaults)
      • via swagger-routes function, mounting both the swagger-ui and swagger-docs and wiring them together
        • by default, mounts the swagger-ui to / and the swagger-spec to /swagger.json
      • via the old swagger-ui & swagger-docs (need to be separately imported from compojure.api.swagger).
      • see https://github.com/metosin/compojure-api/wiki/Swagger-integration for details
(defapi app
  (swagger-routes)
  (GET "/ping" []
    (ok {:message "pong"})))

(defapi app
  {:swagger {:ui "/", :spec "/swagger.json"}}
  (GET "/ping" []
    (ok {:message "pong"})))

  • BREAKING: api-level coercion option is now a function of request => type => matcher as it is documented. Previously required a type => matcher map. Options are checked against type => matcher coercion input, and a descriptive error is thrown when api is created with the old options format.

  • BREAKING: Renamed middlewares to middleware and :middlewares key (restructuring) to :middleware

    • will break at macro-expansion time with helpful exception

  • BREAKING: Middleware must be defined as data: both middleware macro and :middleware restructuring take a vector of middleware containing either

    • a) fully configured middleware (function), or
    • b) a middleware templates in form of [function args]
    • You can also use anonymous or lambda functions to create middleware with correct parameters, these are all identical:
      • [[wrap-foo {:opts :bar}]]
      • [#(wrap-foo % {:opts :bar})]
      • [(fn [handler] (wrap-foo handler {:opts :bar}))]
    • Similar to duct

  • BREAKING: (Custom restructuring handlers only) :parameters key used by restructure-param has been renamed to :swagger.

    • will break at macro-expansion time with helpful exception

  • BREAKING public-resource-routes & public-resources are removed from compojure.api.middleware.

  • BREAKING: compojure.api.legacy namespace has been removed.

Migration guide

https://github.com/metosin/compojure-api/wiki/Migration-Guide-to-1.0.0

Other stuff

  • Additional route functions/macros in compojure.api.core:

    • routes & letroutes, just like in the Compojure, but supporting Routing
    • undocumented - works just like routes but without any route definitions. Can be used to wrap legacy routes which setting the api option to fail on missing docs.

  • top-level api is now just function, not a macro. It takes an optional options maps and a top-level route function.

  • Coercer cache is now at api-level with 10000 entries.

  • Code generated from restructured route macros is much cleaner now

  • Coercion is on by default for standalone (apiless) endpoints.

(fact "coercion is on for apiless routes"
  (let [route (GET "/x" []
                :query-params [x :- Long]
                (ok))]

Migration Guide

  • Routes are collected always from the root (defapi or compojure.api.routes/api-root within that)
  • compojure.api.routes/with-routes is now compojure.api.routes/api-root
  • breaking requires the latest swagger-ui to work
    • [metosin/ring-swagger-ui "2.1.1-M2"] to get things pre-configured
    • or package 2.1.1-M2 yourself from the source.
  • breaking: api ordering is not implemented.
  • breaking: restructuring :nickname is now :operationId
  • breaking: restructuring :notes is now :description
  • swagger-docs now takes any valid Swagger Spec data in. Using old format gives a warning is to STDOUT.

    • Fixes #16: If Schema has many properties, they are now shown in correct order on Swagger-UI
      • hash-map loses the order if it has enough properties
      • ~~Use flatland.ordered.map/ordered-map when Schema has many properties and you want to keep the order intact~~
      • ~~(s/defschema Thingie (ordered-map :a String ...))~~

0.15.0 (10.8.2014)

  • Use latest ring-swagger
  • :body and others no langer take description as third param, instead use :body [body (describe Schema "The description")]
    • describe works also for Java classes :query-params [x :- (describe Long "first-param")]
    • And inside defschema (s/defschema Schema {:sub (describe [{:x Long :y String}] "Array of stuff")})

0.14.0 (9.7.2014)

  • return model coercion returns 500 instead of 400, thanks to @phadej!
  • added support for returning primitives, thanks to @phadej!
(GET* "/plus" []
  :return       Long
  :query-params [x :- Long {y :- Long 1}]
  :summary      "x+y with query-parameters. y defaults to 1."
  (ok (+ x y)))
  • :responses restructuring to (error) return codes and models, thanks to @phadej!
(POST* "/number" []
  :return       Total
  :query-params [x :- Long y :- Long]
  :responses    {403 ^{:message "Underflow"} ErrorEnvelope}
  :summary      "x-y with body-parameters."
  (let [total (- x y)]
    (if (>= total 0)
      (ok {:total (- x y)})
      (forbidden {:message "difference is negative"}))))

      • in future, there could be a special return value coercer forcing all other primitives as Strings

0.13.0 (21.6.2014)

  • first take on removing the global route state => instead of global swagger atom, there is one defined +routes+ var per namespace
