Schema

What is a schema​

  • Everything in Mongoose starts with a Schema
  • Each schema maps to a MongoDB collection and defines the shape of the documents within that collection

String​

const mySchema = new mongoose.Schema({
	name:String,										
	name:{type:String},
	name:{type:String,required:true},
	position:{type:String,default:'engineer'},
	position:{type:String,minLength:5,maxLength:255},
	gender:{type:String,enum:['male','female']},
	name:{type:String,unique:true}
});

Number​

const mySchema = new mongoose.Schema({
	age:Number,										
	age:{type:Number},
	age:{type:Number,required:true},
	age:{type:Number,default:1},
	age:{type:Number,min:0,max:999}
});

Date​

const mySchema = new mongoose.Schema({
	entryDate:Date,										
	entryDate:{type:Date},
	entryDate:{type:Date,required:true},
	entryDate:{type:Date,default:Date.now},
	entryDate:{type:Date,min:'1900-01-01',max:'9999-12-31'}	
});

Boolean​

const mySchema = new mongoose.Schema({
	isDone:Boolean,										
	isDone:{type:Boolean},
	isDone:{type:Boolean,required:true},
	isDone:{type:Boolean,default:false},
});

Array​

const mySchema = new mongoose.Schema({
	tags:[String],										
	tags:{type:[String]},
	tags:{type:[String],required:true},
	tags:{type:[String],default:'test'}
});

const mySchema = new mongoose.Schema({
	custID:mongoose.ObjectId,										
	custID:{type:mongoose.ObjectId},
	custID:{type:mongoose.ObjectId,required:true}
});
