About this course

Writing robust applications requires knowing how to quickly identify and fix errors when they occur. Debugging is a fundamental skill for any Deno developer. This course provides a practical foundation in leveraging Deno's native inspection capabilities to analyze runtime behavior. You will gain confidence in diagnosing issues, setting breakpoints, and examining variable state during execution. What you'll learn: * Understand the Deno runtime architecture and how to enable the V8 inspector protocol. * Configure Deno scripts to pause execution using the inspect flags for initial troubleshooting. * Practice setting up breakpoints, stepping through code, and observing the call stack using standard developer tools. * Apply techniques for debugging asynchronous code and handling promises within the inspection environment. * Master inspecting variable values, modifying state, and evaluating expressions in the DevTools console. * Learn how to use configuration files to streamline debugging setup for complex projects. The course begins by establishing core debugging terminology and setting up the inspection environment. It then progresses through practical exercises focused on execution control, state inspection, and effective use of the integrated developer tools. This course is designed for beginners who are familiar with writing basic Deno code and want to learn professional debugging workflows. No prior experience with code inspection tools is required. Start reading today and transform your approach to error resolution in Deno.
