Luke,
We had the same problem when trying to specify our Facebook App test ID vs production ID. The problem is that I believe mobile-config.js is in regular node land and is read before Meteor even gets started. While definitely not ideal, I solved this with mobile-config.js code that looked like this:
if (this.process.env.NODE_ENV === 'production') {
App.configurePlugin('com.phonegap.plugins.facebookconnect', {
APP_ID: 'XXXXXX', // production FB app ID
APP_NAME: 'My App'
});
}
else {
App.configurePlugin('com.phonegap.plugins.facebookconnect', {
APP_ID: 'XXXXXX', // test FB app ID
APP_NAME: 'My App Development'
});
}
Then, I ran meteor like this:
$ NODE_ENV=production meteor build ../<app-name>-build --server http://<app-server> --mobile-settings settings.json
I put that long command in my package.json file and run it like this:
$ npm run build
