Gatsby Serverless Functions: Building Dynamic APIs

Building static sites is great, but modern web applications require dynamic features like form handling, user authentication, and real-time data integration. Gatsby serverless functions allow you to write server-side code that runs securely and scales automatically, all within your frontend workflow. This text-only course takes you from a static site developer to a full-stack creator by showing you how to write, test, and deploy serverless endpoints. You will learn to handle backend logic safely without the overhead of managing dedicated servers. In this course, you will learn to: 1. Understand the core concepts of serverless architecture and how Gatsby routes API requests. 2. Write clean serverless functions using modern JavaScript conventions. 3. Secure your endpoints with environment variables and proper CORS configurations. 4. Connect your functions to external third-party APIs and databases. 5. Test your API routes locally using modern development workflows. The course begins with foundational serverless definitions and setup basics before moving into hands-on code explanations for handling requests and securing data. This course is designed for frontend developers familiar with Gatsby or React who want to add backend capabilities to their projects, with no prior server administration experience required. Start reading today to unlock the power of serverless backend logic in your web applications.
