nspv-rpc-js

json-rpc for nSPV, with Promises support

• Supports on-the-fly RPC methods using Proxies; all the RPC methods supported by a nSPV binary are available
• Supports multiple instances (different daemons) in the same application
• Works in browser and Nodejs
• Very small codebase
• Uses axios behind the scenes

Instructions

1. require() the module; it imports a class
2. launch a new instance of the class with a config object as the argument; the config object must contain the credentials directly
3. call .config with the new instance object to access its config
4. call .rpc() with the new instance object to access the RPC interface

Usage

const SmartChain = require("nspv-rpc-js");

const config = {
  rpchost: "localhost",
  rpcport: 7771,
};

const komodo = new SmartChain({ config });

console.log(komodo.config); // Prints the config being used by the komodo instance

const komodoRPC = komodo.rpc();

komodoRPC
  .getinfo()
  .then((info) => {
    console.log(info);
  })
  .catch((error) => {
    console.log(error);
    throw new Error(error);
  });

komodoRPC
  .listunspent("RD47yEoA4VGriqjeiLdMVKnuE7x7xqFy9r", false, 5)
  .then((outs) => {
    console.log(outs.utxos.length);
  })
  .catch((error) => console.log(error));

Descriptions of the properties

• HOSTNAME the address at which the nSPV binary is listening for connections
• PORT is the port at which the nSPV binary is listening for connections

Defaults

If the config object is missing the keys: rpchost or rpcport, the default values used are localhost and 7771 respectively
