understanding module.export

[Ken Koontz]

I am working on an express app. I've separated my route logic outside of the app.js file, which I'm using for config. I'm trying to configure my db in app.js and export this into any route module that needs it.

Here is my db code that i'm pulling into app.js.

db file snippet

app.js file snippet

The output from console.log(db); in the app.js file appears to be an empty object. However, when I reference a function such as console.log(db.create) it returns [ Function ]. Why does console.log(db) return {} and not something like {create: [ Function ].....}

console.log hides object's prototype

Either via util.inspect() or console.error("db: %j", db).

Thanks for the help. I'm now having problems with the export. In app.js I export db. In the other module I attempt to use it.

When I require db the variable is undefined. Any suggestions?

Modules are loaded synchronously but I'm guessing your database setup is asynchronous (i.e. done using a callback). You should rewrite the app module in such a way that you're exporting a function that takes a callback, and that callback gets called with the db object as a parameter once it's available. You could also take a look at using something like Cloud9's architect or flatiron's broadway to help manage dependencies by treating them like plugins.
