How to use

• git clone [email protected]:winkler1/flow-eslint-react-demo.git && cd flow-eslint-react-demo && git checkout react-13 && npm install
• npm run lint to confirm eslint working.
• Watch your code: ./node_modules/.bin/onchange "**/*.js" .babelrc .eslintrc .flowconfig -- ./run_checks.sh
• Make changes in src/App.js. As you change, ESLint and Flow should run checks and give feedback.
