In the above fields i need to do unique are User name & Email.So is there any procedure for unique fields in a collection or do manually checking when ever inserts data to a collection each & every time.Please suggest me what to do for this above problem?

Answer 1

Create unique indices on the server. This way, Mongo checks it for you:

List._ensureIndex({username: 1}, {unique: 1});
List._ensureIndex({email: 1}, {unique: 1});

See how Meteor does it for Meteor.users: https://github.com/meteor/meteor/blob/devel/packages/accounts-base/accounts_server.js#L1136
