bitshares

A Bitshares API consuming a websocket connection to an active full node. If you need wallet features, specify an optional RPC connection to your local cli_wallet. Look for several examples in tests. This is work in progress and may have breaking changes. No additional cgo dependencies for transaction signing required. Use it at your own risk.

install

go get -u github.com/denkhaus/bitshares

Install dev-dependencies with

make init

This API uses ffjson. If you change this code you have to regenerate the required static MarshalJSON and UnmarshalJSON functions for all API-structures with

make generate

testing

To test this stuff I use a combined Docker based MainNet/TestNet wallet, you can find here. Operations testing uses generated real blockchain sample code by gen package. To test run:

make test_operations
make test_api

or a long running block (deserialize/serialize/compare) range test.

make test_blocks

code

rpcApiUrl    := "http://localhost:8095" 
wsFullApiUrl := "wss://bitshares.openledger.info/ws"

//Note: The RPC endpoint is optional. If you do not need wallet functions
//pass an empty string as second parameter.

api := api.New(wsFullApiUrl, rpcApiUrl)
if err := api.Connect(); err != nil {
	log.Fatal(err)
}

api.OnError(func(err error) {
	log.Fatal(err)
})

UserID   := types.NewGrapheneID("1.2.253") 
AssetBTS := types.NewGrapheneID("1.3.0") 

res, api.GetAccountBalances(UserID, AssetBTS)
if err != nil {
	log.Fatal(err)
}

log.Printf("balances: %v", res)

For a long application lifecycle, you can use an API instance with latency tester that connects to the most reliable node. Note: Because the tester takes time to unleash its magic, use the above-mentioned constructor for quick in and out.

rpcApiUrl    := "http://localhost:8095" 
wsFullApiUrl := "wss://bitshares.openledger.info/ws"

//Note: The RPC endpoint is optional. If you do not need wallet functions
//pass an empty string as second parameter.

//wsFullApiUrl serves as "quick startup" fallback endpoint here, until the latency tester provides the first results.
api, err := api.NewWithAutoEndpoint(wsFullApiUrl, rpcApiUrl)
if err != nil {
	log.Fatal(err)
}

if err := api.Connect(); err != nil {
	log.Fatal(err)
}

api.OnError(func(err error) {
	log.Fatal(err)
})
