Haskell JSON-RPC client for PegNet daemon

Build Status Coverage Status Hackage License

A JSON-RPC Haskell client for the PegNet API daemon. Allows retrieval of data from PegNet dApp. Each response has special ADT(algebraic data type) that automatically converted from JSON response. Using Remote Monad pattern multiple request can be batched and executed simulatenously, following more robust approach and reducing usage of expensive RPC calls.

Choosing a batching strategy. There are two strategies:

  • Weak - a single command or a single procedure, or
  • Strong - a sequence of commands, optionally terminated by a procedure

  2. Usage
  3. Contributions

Installation

You can install package from Hackage and build with Cabal, but we recommend to use Stack tool. Add to you dependencies in stack.yaml and cabal file dependency - api-rpc-pegnet.

To run and test from repository:

  1. Build with stack 
$ stack build
  1. Load REPL with stack for evaluation 
$ stack repl
  1. execute required methods

Usage

for basic daemon functionality

  1. import with 
import PegNet.RPC.Api

or load in REPL.

  1. build communication session with 
weakSession (traceSendAPI "" $ clientSendAPIWithAlt endpoint)
  1. run required methods inside RPC monad

Usage

You can construct simple session with all methods available for further processings. Check following execution

main = do
  -- build communication session
  let s = weakSession $ traceSendAPI "" $ clientSendAPIWithAlt endpointRemote
  (h, i) <- send s $ do
         h <- reqGetSyncStatus
         i <- reqPegNetIssuance
         b <- reqPegNetBalances "FA38cwer93mmPw1HxjScLmK1yF9iJTu5P87T2vdkbuLovm2YXyss"
         t <- reqGetTransaction "0-e4380e6334b0c42d4d6155fbd1378050b91c02a0df93d7fdfe6656f94c61e7eb"
         r <- reqPegNetRates 213000
         s <- reqGetTransactionStatus "a33d4f334a2658c17d3f44158af75f1c32cc6b2f3de9ddc337064c93043d8db0"
         rich <- reqGetRichList (Just "PEG") 5

         -- return values as N-ary tuple
         return (h, i)
  -- process resulted values
  print h
  -- or use for special business logic

Variables h and i mapped to exact data stucture. All types available for detailed overview in Types directory.
