Deno Runtime

Explore the secure-by-default successor to Node.js. Build modern applications with Deno, featuring native TypeScript support, modern standard library, and URL-based imports.

Adopt a modern, secure-by-default runtime for JavaScript and TypeScript created by the founder of Node.js. Forget node_modules hell; learn to import dependencies directly from URLs. Use Deno's robust built-in toolchain for testing, linting, and formatting without external configuration. This course covers the architecture, security model, and deployment strategies for modern edge-based applications. You will learn how to write secure backend code that requires explicit permissions to access the network or file system.
