Clj-di 0.5.0 API documentation

Defines protocol and creates proxy methods where protocol implementation received as a dependency.

For defining dependency you should:

(defprotocol* http-client
  (get [_ url request])
  (post [_ url request]))

After that you have http-client protocol and get* and post* proxy functions.

Then you need to implement protocol:

(deftype HttpClient
  []
  http-client
  (get [_ url request] (http/get url request))
  (post [_ url request] (http/post url request)))

And register dependency:

(register! :http-client (HttpClient.))

And after that you can use proxy functions, like:

(get* "http://nvbn.github.io/" {})
(post* "http://nvbn.github.io/" {:transit-params {:a 1 :b 2}})

Get dependency by name.

Usage:

(get-dep :http)

Dependency should be registered with register! or with-registered.

Bind dependencies in lexical scope of code block.

Usage:

(let-deps [http :http
           logger :logger]
  ...)

It will work like:

(let [http (get-dep :http)
      logger (get-dep :logger)]
  ...)

Dependencies should be registered with register! or with-registered.

Register dependecies.

Usage:

(register! :logger logger
           :http http-client)

After that you can get dependency with get-dep or let-deps using dependency name (here - :logger and :http).
