      npm install --omit=dev
      
    • Environment Variables

      This application accepts & depends upon these variables to be passed through environment:

      - APP_CORE_LIGHTNING_IP: IP address of this application (cln-application) container (required)
      - APP_CORE_LIGHTNING_PORT: Port on which this application should be served (required)
      - APP_CORE_LIGHTNING_DAEMON_IP: IP address of Core lightning node container (required)
      - APP_CORE_LIGHTNING_WEBSOCKET_PORT: Core lightning's websocket port (required; from cln's config.json; starting with `bind-addr=ws:`)
      - APP_CONFIG_DIR: Path for cln-application's configuration file (required; config.json)
      - COMMANDO_CONFIG: Full Path including file name for commando auth with PUBKEY & RUNE (required)
      - APP_BITCOIN_NODE_IP: IP address of bitcoin node container (required)
      - APP_CORE_LIGHTNING_BITCOIN_NETWORK: Bitcoin network type (optional; for entrypoint.sh; valid values: bitcoin/signet/testnet/regtest)
      - APP_CORE_LIGHTNING_REST_PORT: c-lightning-REST server port (optional; for connect wallet screen)
      - APP_CORE_LIGHTNING_REST_CERT_DIR: Path for c-lightning-REST certificates (optional; for connect wallet screen)
      - APP_CORE_LIGHTNING_DAEMON_GRPC_PORT: Core lightning's GRPC port (optional; future proofing for connect wallet screen)
      - APP_CORE_LIGHTNING_REST_HIDDEN_SERVICE: REST hidden service url (optional; for connect wallet screen; Used for Tor Domain also)
      - DEVICE_DOMAIN_NAME: Device name/IP for lnmessage connect url feature (optional; for connect wallet screen)
      - LOCAL_HOST: Device url for connect url links (optional; for connect wallet screen)
      - APP_MODE: Mode for logging and other settings (valid values: production/development/testing, default: production)
      - SINGLE_SIGN_ON: Flag to bypass application level authentication (valid values: true/false, default: false)
      - APP_PROTOCOL: Protocol on which the application will be served (valid values: http/https, default: http)
      - CORE_LIGHTNING_PATH: Path for core lightning (optional; required for entrypoint.sh)
      

      Set these variables either via terminal OR by env.sh script OR by explicitly loading variables from .env files. Important Note: Environment variables take precedence over config.json variables. Like SINGLE_SIGN_ON will take higher precedence over singleSignOn from config.json.

    • Application Configuration

      This is the config.json file which is required by application's frontend. If the file named config.json is missing at APP_CONFIG_DIR location, one like below will be auto created:

        {
          "unit": "SATS",
          "fiatUnit": "USD",
          "appMode": "DARK",
          "isLoading": false,
          "error": null,
          "singleSignOn": false,
          "password": ""
        }
      
    • Commando Authentication

      • This application utilizes lnmessage and commando for connecting with core lightning node. The connection is trustless and end-to-end encrypted. Commando manages authentication and authorization through runes, which can grant either full or fine-grained permissions.

      • The backend server reads LIGHTNING_PUBKEY & LIGHTNING_RUNE from the COMMANDO_CONFIG file for this communication.

      • Values can either be set manually or script entrypoint.sh can be used to call getinfo and createrune methods and save values in COMMANDO_CONFIG.

      • entrypoint.sh can only run for the locally installed lightning. If cln-application is running remotely then pubkey and rune can be set manually.

      • Sample commando config should look like:

          LIGHTNING_PUBKEY="03d2d3b2...0f8303bfe"
          LIGHTNING_RUNE="iv...4j"
        
    • Start The Application

      • Setup environment variables either via terminal OR by env.sh script OR by explicitly loading variables from .env files.
      • Run start script for starting your application's server at port APP_CORE_LIGHTNING_PORT
        npm run start
      
  • Stores/Marketplaces

    • This application is also available on Umbrel App Store and Start9 OS with one click install.
