This is the code for the Building a LApp with NodeJS + LND workshop at The Lightning Conference. If you're interested in learning to make Lightning apps though, I suggest you check out the Lightning App Tutorial blog post series I put together that this is based off of.

If you are here at the conference, welcome! I'm looking forward to building some cool stuff with you.

• Node.js 8+
• An LND node

Copy the environment configuration file with

cp .env.example .env

Edit the following fields in your new .env file with information about your node. You can get some help finding this info using this tool: https://lightningjoule.com/tools/node-info

• LND_GRPC_URL - The location to connect to your node. If you're running with default settings locally, this should be 127.0.0.1:10009.
• LND_MACAROON - Your readonly.macaroon file, base64 encoded. Run base64 readonly.macaroon in your macaroon directory to get this.
• LND_TLS_CERT - Your TLS certificate, also base 64 encoded. Run base64 tls.cert in your data directory to get this.

If you're on a Windows operating system, you'll need to base64 encode some other way since you won't have the base64 command. If you use an online tool like this one I recommend not uploading any mainnet node credentials.

Install dependencies and run the app with

npm install && npm run dev
