Development on Insomnia can be done on Mac, Windows, or Linux as long as you have NodeJS and Git. See the .nvmrc file located in the project for the correct Node version.

This repository is structured as a monorepo and contains many Node.JS packages. Each package has its own set of commands, but the most common commands are available from the root [package.json](package.json) and can be accessed using the npm run ... command. Here are the only three commands you should need to start developing on the app.

# Install and Link Dependencies
npm run bootstrap

# Run Tests
npm test

# Start App with Live Reload
npm run app-start

If you are on Linux and have problems, you may need to install libfontconfig-dev

# Install libfontconfig-dev
sudo apt-get install libfontconfig-dev

If you are on Windows and have problems, you may need to install Windows Build Tools
