Lndconnect NPM

lndconnect

Generate and parse lndconnect uris https://github.com/LN-Zap/lndconnect ⚡️

This package provides utilities for generating and parsing lndconnect uris.

For more information take a look at the specification of the uri format.

Install

npm install lndconnect --save

Usage

format({ host, cert, macaroon }):

Formats a host / cert / macaroon combo into an lndconnect link.

import { format } from 'lndconnect'

const connectionString = format({
  host: '1.2.3.4:10009',
  cert: 'MIICuDCCAl...',
  macaroon: '0201036c6...',
})

expect(connectionString).toEqual('lndconnect://1.2.3.4:10009?cert=MIICuDCCAl...&macaroon=0201036c6...')

encode({ host, cert, macaroon }):

Encodes a host / cert / macaroon combo and formats into an lndconnect link.

import { encode } from 'lndconnect'

const connectionString = encode({
  host: '1.2.3.4:10009',
  cert: '-----BEGIN CERTIFICATE-----\n...',
  macaroon: '0201036c6...',
})

expect(connectionString).toEqual('lndconnect://1.2.3.4:10009?cert=MIICuDCCAl...&macaroon=AgEDbG5kAr...')

decode(lndconnectUri):

Decodes an lndconnect link into it's component parts (host / cert as utf8 / macaroon as hex)

import { decode } from 'lndconnect'

const { host, cert, macaroon } = decode('lndconnect://1.2.3.4:10009?cert=MIICuDCCAl...&macaroon=AgEDbG5kAr...')

expect(host).toEqual('1.2.3.4:10009')
expect(cert).toEqual('MIICuDCCAl...')
expect(macaroon).toEqual('0201036c6...')

Certificate

encodeCert(cert, format):

Encodes a certificate (String or Buffer) to base64url encoded DER format.

import { encodeCert } from 'lndconnect'

const certPath = path.join(__dirname, 'tls.cert')
const cert = encodeCert(certPath)

// returns base64url encoded DER cert.
expect(cert).toEqual('MIICuDCCAl...')

decodeCert(encodedCert):

Decodes a certificate from base64url encoded DER format to a string.

import { decodeCert } from 'lndconnect'

// pass a base64url encoded DER cert
const cert = decodeCert(encodedCert)

// returns utf8 encoded PEM cert.
expect(cert).toEqual('-----BEGIN CERTIFICATE-----\n...')

Macaroon

encodeMacaroon(macaroon, format):

Encodes a binary macaroon (String or Buffer) to base64url encoded string.

import { encodeMacaroon } from 'lndconnect'

const macaroonPath = path.join(__dirname, 'admin.macaroon')
const macaroon = encodeMacaroon(macaroonPath)

// returns base64url encoded macaroon.
expect(macaroon).toEqual('AgEDbG5kAr...')

decodeMacaroon(encodedMacaroon):

Decodes a base64url encoded macaroon to a hex encoded macaroon.

import { decodeMacaroon } from 'lndconnect'

// pass a base64url encoded macaroon
const macaroon = decodeMacaroon(encodedMacaroon)

// returns hex encoded macaroon.
expect(macaroon).toEqual('0201036c6...')
