Automatically derive bindings for Servant APIs in Reason. Originally build by converting servant-elm to Reason. Types are generated using reason-export.
More docs on Hackage.
A full example of how to integrate Servant and Reason is available at servant-reason-example.
Run the tests if you want a concrete example. They will build a _test-cache directory that contains a sample Reason repository for a servant API. test also contain example output files for different kinds of bindings.
Usage is simple and automatic. If you have an API like the one below
{-# LANGUAGE DataKinds #-}
{-# LANGUAGE DeriveGeneric #-}
{-# LANGUAGE OverloadedStrings #-}
{-# LANGUAGE TypeOperators #-}
import Reason (Spec (Spec), specsToDir, toReasonDecoderSource,
toReasonTypeSource)
import GHC.Generics (Generic)
import Servant.API ((:>), Capture, Get, JSON)
import Servant.Reason (ReasonType, Proxy (Proxy), defReasonImports,
generateReasonForAPI)
data Book = Book
{ name :: String
} deriving (Generic)
instance ReasonType Book
type BooksApi = "books" :> Capture "bookId" Int :> Get '[JSON] BookYou can expose your API to reason with:
module Main where
import Data.Proxy
import Reason
import Data.Text hiding (intercalate, map)
import Db
main :: IO ()
main = do
let code = defReasonImports
: toReasonTypeSource (Proxy :: Proxy Book)
: toReasonDecoderSource (Proxy :: Proxy Book)
: generateReasonForAPI (Proxy :: Proxy BooksApi))
writeFile "Api.re" $ intercalate "\n\n" $ map unpack codeThat's it. You can now include Api.re in a Reason project.
The generated code needs access to two Reason libraries @glennsl/bs-json and bs-fetch. Get the latest install instructions from the upstream repos, but at the time of writing these were:
npm install --save @glennsl/bs-json
npm install --save bs-fetchThen add @glennsl/bs-json and bs-fetch to bs-dependencies in your bsconfig.json:
{
...
"bs-dependencies": ["@glennsl/bs-json", "bs-fetch"]
