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.

Differences between Mould.js and Mongoose

Feature	Mongoose	Mould.js
Schema Level	Application	Database
Features	Full	Minimal

Get Started with Database Level Schema Validation

Attention: mongodb version >= 3.2 required

• Installation

npm install mouldjs --save

• Define Schema

let Mould = require('mouldjs')
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.

• Apply To Db

//with promise
User.applyTo(db, collection)
    .then(...)
    .catch(...);
