Modern Deno Development with Standard and Third-Party Libraries

Deno is reshaping how we build server-side applications, offering a secure-by-default runtime with built-in TypeScript support and a powerful standard library. If you want to move away from complex configuration files and dependency bloat, learning Deno's robust ecosystem is the key. This text-based course guides you from foundational concepts to writing clean, production-ready backend code using Deno's modern library landscape. You will transition from a traditional Node.js mindset to writing native TypeScript without external compilers, utilizing Deno's built-in tools for testing, formatting, and linting. By reading through clear, code-focused explanations, you will learn how to handle file systems, manage network requests, and leverage secure environment variables. What you'll learn: - Understand the core security model of Deno and how to grant explicit permissions for network, file, and environment access. - Use the Deno Standard Library to handle common tasks like path parsing, file system operations, and HTTP serving without external dependencies. - Import and manage third-party modules securely using modern URL imports and import maps. - Implement built-in testing and benchmarking tools to ensure code quality and performance. - Connect to modern databases and external web services using native fetch APIs and modern driver libraries. - Structure a clean, modular Deno application following current industry best practices. We begin with foundational definitions, comparing Deno to other runtimes and exploring its built-in toolchain. From there, you will read through step-by-step implementations of essential libraries, learning how to structure configuration-free projects. This course is designed for beginner to intermediate JavaScript or TypeScript developers who want to explore a modern runtime. No prior experience with Deno is required.
