Which SchemaType in Mongoose is Best for Timestamp?
Edit - 20 March 2016
Mongoose now support timestamps for collections.
Please consider the answer of @bobbyz below. Maybe this is what you are looking for.
Original answer
Mongoose supports a Date type (which is basically a timestamp):
time : { type : Date, default: Date.now }With the above field definition, any time you save a document with an unset time field, Mongoose will fill in this field with the current time.
The current version of Mongoose (v4.x) has time stamping as a built-in option to a schema:
var mySchema = new mongoose.Schema( {name: String}, {timestamps: true} );This option adds createdAt and updatedAt properties that are timestamped with a Date, and which does all the work for you. Any time you update the document, it updates the updatedAt property. Schema Timestamps Docs.
In case you want custom names for your createdAt and updatedAt
const mongoose = require('mongoose'); const { Schema } = mongoose; const schemaOptions = { timestamps: { createdAt: 'created_at', updatedAt: 'updated_at' },};const mySchema = new Schema({ name: String }, schemaOptions);
