Package Exports

bcrpc

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (bcrpc) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Tiny Bitcoin RPC wrapper for node.js

Usage

Each rpc function is exposed as a function in an instantiated RpcAgent. The first arguments are parsed as array of arguments, as expected by that specific rpc function, see Bitcoin-core RPC Docs. The last argument is an optional callback function, if no callback is provided, it will return a promise.

const RpcAgent = require('./rpc');

agent = new RpcAgent({port: 8332, user: 'username', pass: 'password'});

// Using Callbacks
agent.getBlockCount(function (err, blockCount) {
  if (err)
    throw Error(JSON.stringify(err));
  console.log(blockCount);
  agent.getBlockHash(blockCount, function (err, hash) {
    if (err)
      throw Error(JSON.stringify(err));
    console.log(hash);
  })
})


// Using Promises
agent.getBlockCount();
.then((blockCount) => {
  console.log(blockCount);
  return agent.getBlockHash();
})
.then((hash) => {
  console.log(hash);
})
.catch((err) => {
  console.error(err);
  return err;
})
