About this course

Node.js revolutionized server-side JavaScript, but modern development demands better security, built-in TypeScript support, and a streamlined toolchain. Deno delivers exactly that, providing a secure-by-default runtime designed for the modern web. In this text-only course, you will transition from a beginner to a confident Deno developer, learning how to write, run, and secure your backend applications without the overhead of complex configuration files. What you'll learn: 1. Understand the core architecture of Deno and how it differs from older runtimes. 2. Configure granular security permissions for file, network, and environment access. 3. Leverage built-in TypeScript compilation without external build tools. 4. Manage external dependencies cleanly using modern ES modules and import maps. 5. Utilize the comprehensive standard library for common tasks like HTTP servers. 6. Apply modern testing practices using the integrated test runner. You will start with fundamental concepts, setting up your environment, and understanding the secure-by-default philosophy. As you progress, you will read through practical implementations, learning to build a web server and manage external modules. This course is designed for web developers and programming beginners who want to explore modern server-side JavaScript and TypeScript. No prior experience with Deno is required, though a basic understanding of JavaScript is helpful. Start reading today to build faster, more secure backend applications with Deno.
