In loopback 3 I have figured a great way to insert createdAt and updatedAt for a model using a mixin. The mixin name is loopback-ds-timestamp-mixin and you can install its module using the command

 npm i loopback-ds-timestamp-mixin --save

Then you can add the mixin in the mixins property found in server/model-config.json as the following

"mixins": [
  "loopback/common/mixins",
  "../node_modules/loopback-ds-timestamp-mixin",
  "../common/mixins"
]

Finally, you can insert createdAt and updatedAt for a model by specifying

"Timestamp": true

in the mixins property of the model json file.

You can also get more details about this mixin here.
