Extending GraphQL Mutations with Azure Serverless Functions

Modern application development requires connecting flexible APIs with secure, custom backend logic. When standard database mutations are not enough to handle complex operations like password hashing or external integrations, serverless functions provide the perfect extension point. This course teaches you how to bridge GraphQL actions with Azure Functions to create powerful, custom backend workflows. In this written guide, you will learn how to intercept incoming GraphQL mutations, validate input data, and execute custom business logic on a serverless architecture. We focus on modern development standards, including secure credential handling, environment variable configuration, and local testing workflows. What you'll learn: - Understand the core concepts of GraphQL mutations, actions, and serverless architectures - Configure Azure Functions to intercept and process incoming API requests - Extend database mutations to safely handle user arguments like usernames and passwords - Implement secure input validation and error handling inside serverless code - Deploy, test, and debug your serverless functions locally using modern tooling You will start with the fundamental concepts of GraphQL actions and serverless architectures before moving step-by-step through setting up, writing, and securing your custom functions. This written course is designed for beginner backend developers and web developers with a basic understanding of JavaScript and APIs. No prior cloud or serverless experience is required.
