Which SchemaType in Mongoose is Best for Timestamp?

Question

I\'m using Mongoose, MongoDB, and Node.

I would like to define a schema where one of its fields is a date\\timestamp.

I would like to use this field in order

Answer 1

var ItemSchema = new Schema({
    name : { type: String }
});

ItemSchema.set('timestamps', true); // this will add createdAt and updatedAt timestamps

Docs: https://mongoosejs.com/docs/guide.html#timestamps

Answer 2

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);

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.

Answer 4

I would like to use this field in order to return all the records that have been updated in the last 5 minutes.

This means you need to update the date to "now" every time you save the object. Maybe you'll find this useful: Moongoose create-modified plugin

Answer 5

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.

Answer 6

First : npm install mongoose-timestamp

Next: let Timestamps = require('mongoose-timestamp')

Next: let MySchema = new Schema

Next: MySchema.plugin(Timestamps)

Next : const Collection = mongoose.model('Collection',MySchema)

Then you can use the Collection.createdAt or Collection.updatedAt anywhere your want.

Created on: Date Of The Week Month Date Year 00:00:00 GMT

Time is in this format.
