Use loopback framework to add default values

[pulkitsinghal]

While user data such as:

        {
            name:'Aquid Shahwar',
            username: 'shahwarcoder',
            email: '[email protected]', 
            password: 'aquid123',
            createdAt: new Date(),
        }

is perfectly valid. If you want to take your familiarity with the loopback framework further, then take the next step by defining your user's model to perform an automatic value injection for the createdAt field.

References:

1. Look for defaultFn
2. Github has samples too, search code with keywords: defaultfn language:json

Also some tangential concepts and fun reads:

A mixin to automatically generate createdAt and updatedAt Date attributes for loopback Models:

Use Mixins for everything!
