A library taking advantage of purescript-aff to enable pain-free asynchronous AJAX requests and response handling.
bower install purescript-affjax
If you are intending to use the library in a Node.js setting rather than the browser, you will need an additional dependency from npm:
npm install xhr2
You can construct requests with the affjax function:
main = launchAff $ do
res <- affjax $ defaultRequest { url = "/api", method = GET }
liftEff $ log $ "GET /api response: " ++ res.response(defaultRequest is a record value that has all the required fields pre-set for convenient overriding when making a request.)
Or use of a number of helpers for common cases:
main = launchAff $ do
res1 <- get "/api"
liftEff $ log $ "GET /api response: " ++ res1.response
res2 <- post "/api" someData
liftEff $ log $ "POST /api response: " ++ res2.responseSee the module documentation for a full list of these helpers.
When sending data in a request the Requestable class enables automatic conversion into a format that is acceptable for an XHR request. Correspondingly there is a Respondable class for reading data that comes back from the server.
Note: these values and types will most likely be moved into separate libraries at a later date.
