Default params for global and service level objects! (Thanks @Alaneor)
Examples
Global default params
var google = require('googleapis');
google.options({
params: {
// attached to every request
quotaUser: 'user123@example.com'
}
});Service level default params
var google = require('googleapis');
var datastore = google.datastore({
version: 'v1beta2',
params: {
// attached to every request made with datastore
datasetId: 'mydataset123'
}
});
