We switched to ES6 Classes from React.createClass(). Thus your React components extend React.Component.

The .eslintrc file is based on the AirBnb eslintrc.

It also includes many eslint defaults that the AirBnb eslint does not include.

Soon to be in gulpfile....but gulp-eslint depends on eslint depends on

    "eslint-plugin-react": "^2.0.2",

So don't use npm run gulp lint yet.

For now:

bin/lint

Or (from either top level or within client directory)

npm run lint

npm install -g npm-check-updates

Then run this to update the dependencies (starting at the top level).

# Make sure you are in the top directory, then run:
cd client 
rm npm-shrinkwrap.json
npm-check-updates -u
npm install
npm prune
npm shrinkwrap

Then confirm that the hot reload server and the rails server both work fine. You may have to delete node_modules and npm-shrinkwrap.json and then run npm shrinkwrap.

Note: npm prune is required before running npm shrinkwrap to remove dependencies that are no longer needed after doing updates.

Suppose you want to add a dependency to "module_name"....

Before you do so, consider:

1. Do we really need the module and the extra JS code?
2. Is the module well maintained?

cd client
npm install --save module_name@version
# or 
# npm install --save_dev module_name@version
rm npm-shrinkwrap.json
npm shrinkwrap
