Fixing compatibility between Adonis and standard code

Adonis uses ES6 generators in order to make the code more readable. However, this may create some issues when trying to interface with classic node.js code.

Calling a generator function (with yield) from within a normal function

Fixed using the co module.
Example: Requesting a user from the database for verification with passport.

const co = require('co');
...
passport.use('local', new LocalStrategy(
  function (username, password, done) {
    return co(function* () {
      const user = yield User.where('username', username).first().fetch();
      ...
    });
  }
))

Transforming a callback function into a generator function

Done using promises.

Example:

class Recommendation {
...
  addLike (userId, itemId, omitUpdate) {
    return new Promise((resolve, reject) => {
      raccoon.liked(userId, itemId, omitUpdate, function(results) {
        resolve(results)
      })
    })
  }
...
}

Usage: yield Recommendation.addLike(userId, itemId, true);
