Methods for working with the Lightning Network

LND Authentication

To connect to an LND node, authentication details are required.

Export credentials via CLI: balanceofsatoshis: npm install -g balanceofsatoshis and export via bos credentials --cleartext

Or export them manually:

Run base64 on the tls.cert and admin.macaroon files to get the encoded authentication data to create the LND connection. You can find these files in the LND directory. (~/.lnd or ~/Library/Application Support/Lnd)

base64 ~/.lnd/tls.cert | tr -d '\n'
base64 ~/.lnd/data/chain/bitcoin/mainnet/admin.macaroon | tr -d '\n'

You can then use these to interact with your LND node directly:

const {authenticatedLndGrpc} = require('lightning');

const {lnd} = lnService.authenticatedLndGrpc({
  cert: 'base64 encoded tls.cert file',
  macaroon: 'base64 encoded admin.macaroon file',
  socket: '127.0.0.1:10009',
});

To access unauthenticated methods like the wallet unlocker, use unauthenticatedLndGrpc instead.

Methods

authenticatedLndGrpc

Initiate an gRPC API Methods Object for LND authenticated methods.

{
  [cert]: <Base64 or Hex Serialized LND TLS Cert>
  macaroon: <Base64 or Hex Serialized Macaroon String>
  [socket]: <Host:Port String>
}

@throws
<Error>

@returns
{
  lnd: {
    autopilot: <Autopilot gRPC Methods Object>
    chain: <ChainNotifier gRPC Methods Object>
    default: <Default gRPC Methods Object>
    invoices: <Invoices gRPC Methods Object>
    router: <Router gRPC Methods Object>
    signer: <Signer gRPC Methods Object>
    wallet: <WalletKit gRPC Methods Object>
  }
}

Example:

const lnService = require('lightning');
const {lnd} = lnService.authenticatedLndGrpc({
  cert: 'base64 encoded tls.cert',
  macaroon: 'base64 encoded admin.macaroon',
  socket: '127.0.0.1:10009',
});

unauthenticatedLndGrpc

Unauthenticated gRPC interface to the Lightning Network Daemon (LND).

Make sure to provide a cert when using LND with its default self-signed cert

{
  [cert]: <Base64 or Hex Serialized LND TLS Cert String>
  [socket]: <Host:Port String>
}

@throws
<Error>

@returns
{
  lnd: {
    unlocker: <Unlocker LND GRPC Api Object>
  }
}

Example:

const {unauthenticatedLndGrpc} = require('lightning');
const {lnd} = unauthenticatedLndGrpc({});
