ln-prism

A typescript implementation of Lightning Prisms

Running with docker

docker run --rm -it \
	--name ln-prism
	-p 3000:3000 \
	-v $(pwd)/data:/data \
	-e DB_PATH=/data/splits.json \
	-e LNBITS_URL="https://legend.lnbits.com" \
	-e LNBITS_ADMIN_KEY="<lnbits admin key>" \
	-e LOGIN_USER=admin \
	-e LOGIN_PASSWORD=changeme \
	ghcr.io/hzrd149/ln-prism

Then you can open http://localhost:3000/admin

Running from source

NodeJS and yarn are required to build and run the app

If you dont have either installing via nvm is probably the easiest way to set them up

git clone https://github.com/hzrd149/ln-prism.git
cd ln-prism
# install dependencies
yarn install
yarn build
# copy the example config
cp .env.example .env
# edit the config
nano .env
# start the dev server
yarn dev

Start the tunnel using yarn tunnel then start the dev server using yarn dev

Configuration

All configuration is done through environment variables

• DB_PATH the path to the json file where data will be stored (default ./splits.json)
• PORT http server port (default 3000)
• LNBITS_URL URL to the lnbits instance ( this can be a local address, eg http://192.168.1.100:8000 or http://umbrel.local:3007 )
• LNBITS_ADMIN_KEY The admin key for the wallet, used to create and pay invoices
• LOGIN_USER The username for the /admin dashboard (default admin)
• LOGIN_PASSWORD The password for the /admin (if its not set then the /admin routes will be publicly accessible)

Public access

For the lightning addresses and the LNURL endpoints to work the app needs to be publicly accessible and served over https
