Serverless JavaScript with Netlify Functions and JSON

Modern web development no longer requires setting up complex, expensive servers just to handle API requests. By utilizing serverless architecture, you can run backend code on demand, saving time and resources. This course guides you through the process of writing, testing, and deploying serverless functions that return structured JSON data. You will start by understanding the foundational concepts of serverless architecture and HTTP communication, then move step-by-step into writing clean, modern JavaScript for backend environments. What you will learn: Understand serverless architecture and how cloud functions execute on demand; Configure a Netlify environment for local development and live deployment; Write JavaScript functions to handle incoming HTTP requests and format JSON responses; Handle CORS, set appropriate headers, and manage secure API routing; Implement modern JavaScript practices including async/await and environment variables; Integrate your serverless endpoints with frontend web applications. The course begins with core terminology and configuration basics before walking you through writing practical serverless functions and deploying them to production. This course is designed for beginner developers, frontend engineers looking to expand into backend logic, and web creators with basic JavaScript knowledge.
