Deno Debugger

What it does

This skill provides debugging capabilities for Deno applications. It allows you to step through code, inspect variables, and set breakpoints within a Deno environment. This facilitates identifying and resolving issues in your Deno projects more effectively than relying solely on print statements or error logs.

When to use it

• Troubleshooting runtime errors: When encountering unexpected behavior or crashes in a Deno application, this skill can help pinpoint the exact location of the problem.
• Understanding complex code: Stepping through unfamiliar Deno codebases allows for better comprehension of logic flow and variable interactions.
• Debugging asynchronous operations: Deno's asynchronous nature can be challenging to debug; this skill provides tools to trace execution across async functions and promises.
• Validating algorithm correctness: When developing algorithms or complex calculations in Deno, use the debugger to verify that each step produces the expected results.

Key capabilities

• Stepping through code line by line
• Inspecting variable values at runtime
• Setting breakpoints to pause execution
• Debugging asynchronous functions and promises

Example prompts

• "Debug my Deno application and tell me what's happening on line 25."
• "Set a breakpoint in main.ts when the x variable is greater than 10."
• "Step through this function to understand how it calculates the result."

Tips & gotchas

• Requires familiarity with Deno and its syntax. The debugger's effectiveness depends on understanding the code being debugged.
