Node.js should be installed using NVM. NVM is a Node.js version manager and allows you to easily install, switch between and uninstall different Node versions. The currently used version of Node.js can be found in our package.json file.
Yarn is a much faster dependency manager than NPM created by Facebook.
We don't recommend installing Yarn via Homebrew as it will also install Node.js if you don't yet have it and you may run into conflicts with what we install via NVM.
Install Yarn using the following command:
npm -g install yarn
After installing Yarn, run the command:
which yarn
You should see output like the following:
/Users/{yourUser}/.nvm/versions/node/v8.6.0/bin/yarn
In order to start the application, we need to install our NPM dependencies, build our assets and start a local development server:
yarn start
This installs the dependencies from our package.json file, builds the app and starts a webpack-dev-server at http://localhost:9999. Our application uses hot-reloading so any changes made to the application files will be reloaded without a page reload.
