BCHD gRPC Interface for Node.js Clients

Install

npm install grpc-bchrpc-node --save (see web version)

Build from source (from ./bchrpc.proto)

1. Install Protocol Compiler from: https://github.com/protocolbuffers/protobuf
2. npm install
3. npm run build && tsc

Example usage

In this simple example we create a new client that connects to bchd.greyh.at:8335 by default. We call getRawTransaction and then print the results to the console. We use reverseOrder in call to getRawTransaction because BCHD works with transaction hash not the conventional reversed hash/txid.

let grpc = new GrpcClient();
let txid = "11556da6ee3cb1d14727b3a8f4b37093b6fecd2bc7d577a02b4e98b7be58a7e8";
let res = await grpc.getRawTransaction({ hash: txid, reverseOrder: true });
console.log(Buffer.from(res.getTransaction_asU8()).toString('hex'));
