Question

What I’m trying to do here is access the context property (or context.settings, more specifically) from within the ready function in the same object. I’m not sure what the correct syntax is to do this.

here’s the code:

module.exports = {
    context: {
        settings: require('./settings')
    },
    listen: function(callback) {
      listen(context.settings.http.port);
      callback(null);
    },
    ready: function (err) {
      if (err)
      {
        throw err;
      }
      console.log("Ready and listening at http://localhost:" + context.settings.http.port);
    }
};

just for clarification, I’m referring to the line console.log("Ready and listening at http://localhost:" + context.settings.http.port);

Edit: a bit more context (ha)

I did try this.context.settings.http.port, but I get
TypeError: Cannot read property 'settings' of undefined.

Here’s the contents of settings.js, just to be sure…

module.exports = { 
  db: {
    host: '127.0.0.1',
    port: 27017,
    name: 'jsblogdemo'
  },
  http: {
    port: 3000
  }
};

Thanks!

Another possibility is this:

module.exports = (function() {
    var context = {
        settings: require('./settings')
    },
    listen = function(callback) {
      listen(context.settings.http.port);
      callback(null);
    },
    ready = function (err) {
      if (err)
      {
        throw err;
      }
      console.log("Ready and listening at http://localhost:" + 
                    context.settings.http.port);
    };

    return {
        // context: context, // needed?
        listen: listen,
        ready: ready
    };
}());

Then the functions have local access to the context object without any worries about how they’re called. And the context object can be kept entirely private if you like.
