Some notes from AF Hack Day 2019

• Getting started with React: https://facebook.github.io/create-react-app/docs/getting-started

npx create-react-app users

Put webpacker in the Gemfile

rails webpacker:install

rails webpacker:install:react

npm run build

Getting GitHub developer credentials

Visit your GitHub profile > Settings > Developer Tools > New GitHub App

• The app name can be whatever your heart desires.
• Homepage URL: http://localhost:3000
• User authorization callback URL: http://localhost:3000/users/auth/github/callback
• User permissions > Emails: set to read-only
• Where can this app be installed? Only on this account for development (Unsure 100%)

Setting up the environment

• At the root directory of the project, make a copy of .env.example by running: cp .env.example .env.sh
• Use the credentials provided by GitHub to fill out the OMNI-AUTH variables
• Run . .env.sh to export the variables in the terminal you plan on running the backend from, otherwise the server won't know about those credentials.
  • Note: you'll need to export this for every new terminal window you plan on running the backend from.
• bundle install and bundle exec rails server to get your now GitHub enabled app up on localhost:3000.
  • Note: if you have trouble with the pg gem, try gem uninstall pg and immediately reinstalling with gem install pg.
