Express: Best way to share a JS config file between client and server

I have a

file that has all my app settings inside it. Some of these settings need to be shared with front-end scripts as well as back-end.

I have some confidential variables that I don't want to be exposed to the front-end though. Do any NodeJS/ExpressJS wizz kids have any good solutions to this?

Do you keep your common config data in a
location and confidential server-side data separate above the exposed

Thanks guys


Using express-expose to share (or 'expose') data from the server to the client works pretty well. As Raynos said, I would keep confidential variables as environment variables and then you may be able to safely expose all of your settings.

Or you can do something like create a 'shared' object in your settings. Like this:

app.set('shared', {
    setting1: mydata
  , setting2: new OAuth(...)
  , setting3: { ... }

Which allows you to access the settings as app.setting.shared.setting1 on the server and then you can app.expose(app.setting.shared) so your client side JS can access the same object.
