Introduction

RTL is now enabled to manage lightning nodes running C-Lightning.

Follow the below steps to install and setup RTL to run on C-Lightning.

Pre-requisites:

1. Functioning C-Lightning node. Follow install instructions on their github
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:

To download a specific RTL version follow the instructions on the release page

To download from master (not recommended):

First time setup

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

• Copy the file Sample-RTL-Config.json from ./RTL/docs to ./RTL and rename it 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.
