fulcro-http-remotecljs

                          make-xhrio make-xhrio}
                     :as options})

Create a remote that (by default) communicates with the given url (which defaults to /api).

The options map can contain:

  • :url - The URL to contact
  • :request-middleware - See below
  • :response-middleware - See below
  • :make-xhrio - A constructor function to build a goog.net.XhrIo object, initialized however you see fit.
  • :preprocess-error - A (fn [xhrio-result] fulcro-result). Defaults to #(merge % {:status-code 500}).

The request middleware is a (fn [request] modified-request). The request will have :url, :body, :method, and :headers. The request middleware defaults to wrap-fulcro-request (which encodes the request in transit+json). The result of this middleware chain on the outgoing request becomes the real outgoing request. It is allowed to modify the url. If the the request middleware returns a corrupt request or throws an exception then the remote code will immediately abort the request. The return value of the middleware will be used to generate a request to :url, with :method (e.g. :post), and the given headers. The body will be sent as-is without further translation.

response-middleware is a function that returns a function (fn [response] mod-response) and defaults to wrap-fulcro-response which decodes the raw response and transforms it back to a response that Fulcro can merge.

The response will be a map containing the :outgoing-request which is the exact request sent on the network; :body, which is the raw data of the response. Additionally, there will be one or more of the following to indicate low-level details of the result: :status-code, :status-text, :error-code (one of :none, :exception, :http-error, :abort, or :timeout), and :error-text. Middleware is allowed to morph any of this to suit its needs.

DEPRECATED: If the response middleware includes a :transaction key in the response with EQL, then that EQL will be used in the resulting Fulcro merge steps. This can seriously screw up built-in behaviors. You are much better off ensuring that your query matches the shape of the desired response in most cases.

The definition of remote-error? in the application will deterimine if happy-path or error handling will be applied to the response. The default setting in Fulcro will cause a result with a 200 status code to cause whatever happy-path logic is configured for that specific response's processing. For example, see m/default-result-action! for mutations, and df/internal-load for loads. The :body key will be considered the response to use, and the optional :transaction key an override to the EQL query used for any merges.

See the top-level application configuration and Developer's Guide for more details.

Create a remote that (by default) communicates with the given url (which defaults to `/api`).

The options map can contain:

* `:url` - The URL to contact
* `:request-middleware` - See below
* `:response-middleware` - See below
* `:make-xhrio` - A constructor function to build a goog.net.XhrIo object, initialized however you see fit.
* `:preprocess-error` - A `(fn [xhrio-result] fulcro-result)`. Defaults to #(merge % {:status-code 500}).

The request middleware is a `(fn [request] modified-request)`. The `request` will have `:url`, `:body`, `:method`, and `:headers`. The
request middleware defaults to `wrap-fulcro-request` (which encodes the request in transit+json). The result of this
middleware chain on the outgoing request becomes the real outgoing request. It is allowed to modify the `url`.
If the the request middleware returns a corrupt request or throws an exception then the remote code
will immediately abort the request. The return value of the middleware will be used to generate a request to `:url`,
with `:method` (e.g. :post), and the given headers. The body will be sent as-is without further translation.

`response-middleware` is a function that returns a function `(fn [response] mod-response)` and
defaults to `wrap-fulcro-response` which decodes the raw response and transforms it back to a response that Fulcro can merge.

The response will be a map containing the `:outgoing-request` which is the exact request sent on the network; `:body`, which
is the raw data of the response. Additionally, there will be one or more of the following to indicate low-level
details of the result: `:status-code`, `:status-text`, `:error-code` (one of :none, :exception, :http-error, :abort, or :timeout),
and `:error-text`.  Middleware is allowed to morph any of this to suit its needs.

progress%cljs

(progress% progress)
(progress% progress phase)

Takes the progress report from the progress network event and returns a number between 0 and 100. phase can be :overall, :sending, or :receiving. When set to :overall then the send phase will count for progress points between 0 and 49, and receiving phase will account for 50 to 100. When set to :sending or :receiving the entire range will count for that phase only (i.e. once sending is complete this function would return 100 throughout the receiving phase.)

If total is unknown, then this function returns 0.

The additional handlers are used to encode new data types into transit. transit-transformation is a function of one argument returning a transformed transit value (like you would pass using the :transform option of transit).

This returns a function that will decode a transit response iff the resulting status code is 200 and the body is not empty. For errant status codes and empty body: the response body will become an empty map.

No arguments: Returns a function that can process responses, that is not further chained. handler: If supplied, the result of this transformation will be passed through the handler. addl-transit-handlers is equivalent to the :handlers option in transit: a map from data type to handler.
