In schema explorer, right click a collection Schema, and have the option to "Generate Script". This would generate a js file such as:

var Comments = new Schema({
title : String
, body : String
, date : Date
});

Alternatively or additionally, you could click the collection, and "Generate Script" and it would generate a script for creating the schema AND indexes. It would also be helpful to be able to perform this at the database level, which would generate the script for every collection in the database.
