Configure and Use a Azure Serverless Function

In this lesson, we'll extend our User table mutation to accept username and password arguments. Then we'll intercept this mutation with the serverless function that we have set up.

Extend a Mutation with a Azure serverless function with GraphQL Actions

Intercept requests from a GraphQL mutation using a [Serverless Function](https://azure.microsoft.com/en-us/services/functions/?WT.mc_id=egghead-screencast-chnwamba). Use this function to encrypt user's passwords before persisting them to the database.
