Setting Up mongo

[Aeal]

Im pretty sure this is a user error. I am trying to connect to a local database and I change the development url in the congfiguration to point to my local instance, but when I run grunt serve I get an error saying required MongoStore option db missing. This looks like an awesome package and thank you for putting it together I just need some help getting started!

Could you post your configuration and the error? Also, does it run with the default configuration?

The problem is in this snippet generated by default config:

    app.use(express.session({
      secret: 'angular-fullstack secret',
      store: new mongoStore({
        url: config.mongo.uri,
        collection: 'sessions'
      })
    }));

Which are lines 46-52 from express.js.
They should probably be:

    app.use(express.session({
      secret: 'angular-fullstack secret',
      store: new mongoStore({
        url: config.mongo.url + '/sessions'
      })
    }));

There is also a 'mongoose_connection' option in mongoStore, which could be used also.

I think the problem here is in the configuration.

In config.js lodash.extend() is used to combine the global config values with the environment specific config values.

In all.js

module.exports = {
  root: rootPath,
  port: process.env.PORT || 3000,
  mongo: {
    options: {
      db: {
        safe: true
      }
    }
  }
};

In development.js

module.exports = {
  env: 'development',
  mongo: {
    uri: 'mongodb://localhost/fullstack-dev'
  }
};

In config.js

module.exports = _.extend(
    require('./env/all.js'),
    require('./env/' + process.env.NODE_ENV + '.js') || {});

extend() is not recursive and will not merge the mongo object in these config hashes so the environment specific mongo overwrites the one in all.js. You end up with a mongo object that has just the uri property and no options property.

There are two ways to fix this, the easiest is to replace _.extend(...) in config.js with _.merge(...), this will do a "deep extend" and merge the full object trees. The other is to flatten the config hierarchy and have something like mongoUri and mongoConfig, but then you have to update any references to the mongo config value in the rest of the codebase.
