mongoose-timestamp

Mongoose plugin that adds createdAt and updatedAt auto-assigned date properties

Mongoose Timestamps Plugin

Simple plugin for Mongoose which adds createdAt and updatedAt date attributes that get auto-assigned to the most recent create/update timestamp.

Installation

npm install mongoose-timestamp

Usage

var timestamps = require('mongoose-timestamp');
var UserSchema = new Schema({
    username: String
});
UserSchema.plugin(timestamps);
mongoose.model('User', UserSchema);
var User = mongoose.model('User', UserSchema)

The User model will now have createdAt and updatedAt properties, which get automatically generated and updated when you save your document.

var user = new User({username: 'Prince'});
user.save(function (err) {
  console.log(user.createdAt); // Should be approximately now 
  console.log(user.createdAt === user.updatedAt); // true 
  // Wait 1 second and then update the user 
  setTimeout( function () {
    user.username = 'Symbol';
    user.save( function (err) {
      console.log(user.updatedAt); // Should be approximately createdAt + 1 second 
      console.log(user.createdAt < user.updatedAt); // true 
    });
  }, 1000);
});

You can specify custom property names by passing them in as options like this:

mongoose.plugin(timestamps,  {
  createdAt: 'created_at', 
  updatedAt: 'updated_at'
});

Any model's updatedAt attribute can be updated to the current time using touch().
