Introduction

RTL is now enabled to manage an Eclair node.

Follow the below steps to install and setup RTL to run on Eclair.

Pre-requisites:

1. Functioning Eclair node v0.4.1 or above. Follow install instructions on their github page.
2. Bitcoin core v0.19.1 or above (this is an Eclair dependency).
3. NodeJS - Can be downloaded here

Installation:

Eclair is integrated with RTL v0.8.0 and above. To download a specific RTL version follow the instructions on the release page

To download from master (not recommended) follow the below instructions:

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 eclair.conf for 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 ECL, indicating that RTL is connecting to an Eclair node.
• lnServerUrl - complete url with ip address and port of the eclair server.
• multiPass - Specify the password (in plain text) to access RTL. This password will be hashed and not stored as plain text.
• configPath (Optinal) - Full path of the folder containing eclair.conf including the file name. Can be used for the basic password authentication through eclair.api.password.
• lnApiPassword (Mandatory if configPath is missing) - The same value from eclair.conf's eclair.api.password should be provided directly here. It will be used for Eclair API authentication.

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.
