Module: CardanoUp::Launcher

Defined in:
lib/cardano-up/launcher.rb

Overview

Start/stop cardano-node and cardano-wallet on your system.

For Linux and MacOS it will attempt to start separate screen sessions for wallet and node respectively, therefore ‘screen’ tool is required on your system. If screen is not present you can install it using your package manager for instance:

# MacOS:
brew install screen
# Linux:
sudo apt-get install screen

For Windows it will attepmt to install cardano-node and cardano-wallet as Windows services using ‘nssm’ tool. Nssm can be installed via choco package manager:

choco install nssm
