Mould.js

Define Schema on Database level.

Document validation has been introduced to MongoDb since version 3.2 . Before that, we could only define schema on application level.

let User = new Mould({
    name  : {$type: 'string', $exists: true},
    age   : {$type: 'int', $lt: 200},
    email : {$regex: \"^[a-zA-Z0-9_.+-]+@[a-zA-Z0-9-]+\.[a-zA-Z0-9-.]+$"\}
    sex   : {$in: ['male','female','unknown']}
});

check full schema lists.
