1. Clone the repo
2. cd leflux
3. npm install

Once the entire internet has been cloned into your node_modules folder you'll need to create src/config, into which you will need to place a couple of files: oauth.js and session.js. These are files which contain secrets and keys, so you can either create the appropriate values, or you can put some placeholder info in:

// oauth.js - do not use in production!
// @see https://cloud.google.com/nodejs/getting-started/authenticate-users
module.exports = {
  clientID: 'lolztehclientid',
  clientSecret: 'suchhiddenmanysecretwow',
  callbackURL: 'http://localhost:8080/auth/google/callback',
  accessType: 'offline'
};

// session.js - do not use in production!
// @see https://cloud.google.com/nodejs/getting-started/authenticate-users
module.exports = {
  resave: false,
  saveUninitialized: false,
  secret: 'totallyasecret',
  signed: true,
  memcacheURL: 'localhost:11211'
};

Finally, with that done you should be able to run: npm run dev.

The videos are not included in the repo, but rather are served from a Google Cloud Storage bucket. They are served with CORS headers, meaning that you will need to run the local copy of the server at port 8080.
