apiclj

(api & body)

Returns a ring handler wrapped in compojure.api.middleware/api-middlware. Creates the route-table at api creation time and injects that into the request via middlewares. Api and the mounted api-middleware can be configured by optional options map as the first parameter:

(api
  {:exceptions {:handlers {:compojure.api.exception/default my-logging-handler}}
   :api {:invalid-routes-fn (constantly nil)}
   :swagger {:spec "/swagger.json"
             :ui "/api-docs"
             :data {:info {:version "1.0.0"
                           :title "My API"
                           :description "the description"}}}}
  (context "/api" []
    ...))

direct api options:

  • :api All api options are under :api.
    • :invalid-routes-fn A 2-arity function taking handler and a sequence of invalid routes (not satisfying compojure.api.route.Routing) setting value to nil ignores invalid routes completely. defaults to compojure.api.routes/log-invalid-child-routes
    • :disable-api-middleware? boolean to disable the api-middleware from api.
  • :swagger Options to configure the Swagger-routes. Defaults to nil. See compojure.api.swagger/swagger-routes for details.

api-middleware options

See compojure.api.middleware/api-middleware for more available options.

Opinionated chain of middlewares for web apis. Takes optional options-map.

Exception handlers

An error handler is a function of exception, ex-data and request to response.

When defining these options, it is suggested to use alias for the exceptions namespace, e.g. [compojure.api.exception :as ex].

Default:

{::ex/request-validation  ex/request-validation-handler
 ::ex/request-parsing     ex/request-parsing-handler
 ::ex/response-validation ex/response-validation-handler
 ::ex/default             ex/safe-handler}

Note: Because the handlers are merged into default handlers map, to disable default handler you need to provide nil value as handler.

Note: To catch Schema errors use {:schema.core/error ex/schema-error-handler}.

Options

  • :exceptions for compojure.api.middleware/wrap-exceptions (nil to unmount it)

    • :handlers Map of error handlers for different exception types, type refers to :type key in ExceptionInfo data.
  • :formats for Muuntaja middleware. Value can be a valid muuntaja options-map, a Muuntaja instance or nil (to unmount it). See https://github.com/metosin/muuntaja/blob/master/doc/Configuration.md for details.

  • :middleware vector of extra middleware to be applied last (just before the handler).

  • :ring-swagger options for ring-swagger's swagger-json method. e.g. {:ignore-missing-mappings? true}

  • :coercion A function from request->type->coercion-matcher, used in endpoint coercion for types :body, :string and :response. Defaults to compojure.api.middleware/default-coercion Setting value to nil disables all coercion.

  • :components Components which should be accessible to handlers using :components restructuring. (If you are using api, you might want to take look at using wrap-components middleware manually.). Defaults to nil (middleware not mounted).

Returns a ring handler wrapped in compojure.api.middleware/api-middlware.
Creates the route-table at api creation time and injects that into the request via
middlewares. Api and the mounted api-middleware can be configured by optional

       :api {:invalid-routes-fn (constantly nil)}
       :swagger {:spec "/swagger.json"

resourceclj

(resource data)

Creates a nested compojure-api Route from enchanced ring-swagger operations map. By default, applies both request- and response-coercion based on those definitions.

Extra keys:

  • :middleware Middleware in duct-format either at top-level or under methods. Top-level mw are applied first if route matches, method-level mw are applied next if method matches

  • :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

  1. special keys :handler and/or :async-handler either under operations or at top-level. They should be 1-ary and 3-ary Ring handler functions, respectively, that are responsible for the actual request processing. Handler lookup order is the following:

3.1) If called asynchronously, operations-level :async-handler 3.2) Operations-level :handler 3.3) If called asynchronously, top-level :async-handler 3.4) Top-level :handler

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

  2. 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"}))})

Creates a nested compojure-api Route from enchanced ring-swagger operations map.
By default, applies both request- and response-coercion based on those definitions.

Extra keys:

- **:middleware**     Middleware in duct-format either at top-level or under methods.
                      Top-level mw are applied first if route matches, method-level
                      mw are applied next if method matches

- **: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 keys `:handler` and/or `:async-handler` either under operations or at top-level.
They should be 1-ary and 3-ary Ring handler functions, respectively, that are responsible
for the actual request processing. Handler lookup order is the following:

  3.1) If called asynchronously, operations-level :async-handler
  3.2) Operations-level :handler
  3.3) If called asynchronously, top-level :async-handler
  3.4) Top-level :handler

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))}))}
