ln-addr-test

Simple Express server for testing Lightning Addresses with a LN service. Conforms to the spec outlined at lightning-address for generating an LNURL pay object.

This a fork from @blastshielddown"s work. The key differences, apart from some refactors, are:

• the use of ln-service to avoid dealing with grpc ourselves,
• Dockerfile to run the server in a Docker environment.

Configured to run with an LND backend. Requires the passing of environment variables with the following values:

Variable	Description
LND_MACAROON	LND admin macaroon in base64
LND_CERT	LND TLS cert in base64
LND_HOST	LND Host
LND_PORT	LND Port (default to 10009)
APP_PORT	App port (default to 3000)
CALLBACK_HOST	Host for the url callback (default to localhost)

Usage

Bare metal

pnpm install && pnpm start

Example:

curl http://127.0.0.1:3000/.well-known/lnurlp/testman
