Azure Serverless Computing Cookbook - Third Edition

By: Praveen Kumar Sreeram

Overview of this book

This third edition of Azure Serverless Computing Cookbook guides you through the development of a basic back-end web API that performs simple operations, helping you understand how to persist data in Azure Storage services. You'll cover the integration of Azure Functions with other cloud services, such as notifications (SendGrid and Twilio), Cognitive Services (computer vision), and Logic Apps, to build simple workflow-based applications. With the help of this book, you'll be able to leverage Visual Studio tools to develop, build, test, and deploy Azure functions quickly. It also covers a variety of tools and methods for testing the functionality of Azure functions locally in the developer's workstation and in the cloud environment. Once you're familiar with the core features, you'll explore advanced concepts such as durable functions, starting with a "hello world" example, and learn about the scalable bulk upload use case, which uses durable function patterns, function chaining, and fan-out/fan-in. By the end of this Azure book, you'll have gained the knowledge and practical experience needed to be able to create and deploy Azure applications on serverless architectures efficiently.

Sending an email notification dynamically to the end user

In the previous recipe, we hard-coded most of the attributes related to sending an email to an administrator as there was just one administrator. In this recipe, we will modify the previous recipe to send a Thank you for registration email to the users themselves.

Getting ready

Make sure that the following steps are configured properly:

  • The SendGrid account is created and an API key is generated in the SendGrid portal.
  • An App settings configuration is created in the configuration of the function app.
  • The App settings key is configured in the SendGrid output (message) bindings.

How to do it…

In this recipe, we will update the code in the run.csx file of the following Azure functions:

  • RegisterUser
  • SendNotifications

Let's make changes to the RegisterUser function to accept the email parameter by performing...
