Introduction

RTL can now be run to manage a c-lightning node via the UI. Please note, this integration is currently in alpha testing phase and can be bug prone.

Follow the below steps to install and setup RTL to run on c-lightning.

Pre-requisites:

1. Functioning C-lightning node
2. NodeJS - Can be downloaded here
3. Cl-Rest - Ensure that cl-rest API server is installed and running. Install instructions here
4. Copy the access.macaroon file from cl-rest to the device, on which RTL will be installed

Architecture

Installation:

First time setup

• Fetch sources from RTL git repository, by executing the below on the command prompt:

$ git clone https://github.com/Ride-The-Lightning/RTL.git

• Change directory to RTL folder:

$ cd RTL

• Fetch the production dependencies by running: $ npm install --only=prod

Or: Update existing build

$ cd RTL
$ git reset --hard HEAD
$ git clean -f -d
$ git pull
$ npm install --only=prod

Prep for Execution

RTL requires its own config file RTL-Config.json, to start the server and provide user authentication on the app.

• Rename sample-RTL-Config.json file to RTL-Config.json.
• Locate the complete path of the readable access.macaroon from cl-rest on your node.
• Modify the RTL conf file per the example file below

Ensure that the follow values are correct per your config:

• lnImplementation - This should be CLT, indicating that RTL is connecting to a c-lightning node.
• macaroonPath - Path of the folder containing access.macaroon file from cl-rest server.
• lnServerUrl - complete url with ip address and port of the cl-rest server.
• multiPass - Specify the password (in plain text) to access RTL. This password will be hashed and not stored as plain text.
• configPath (optional) - File path of the c-lightning config file, if RTL server is local to the c-lightning server.

Start the server and access the app

Run the following command:

$ node rtl

If the server started successfully, you should get the below output on the console:

$ Server is up and running, please open the UI at http://localhost:3000

Open your browser at the following address: http://localhost:3000 to access the RTL app.
