Description

When the user logs in, create a database entry for them if it does not already exist.

Collection: users
Document ID: The user's Firebase Auth ID
Document Data:

{
    created: Date; // The date at which the document is created

    }
}

User Story

As a user
I want to have a database entry
So that I data can be stored about me

Notes

• Firebase's serverTimestamp() method should be used for the created field
• The user's GitHub ID can be accessed using the uid field within the providerData array on a user's auth account. Use the providerData entry which has a providerId of github.
