Node.js - Debugging and Profiling
You set a breakpoint in VS Code but the debugger never pauses when running your Node.js app. Which of these is the most likely cause?
AThe Node.js version is too new
BYou forgot to save the file before running
CThe launch.json file is missing or misconfigured
DBreakpoints only work in browser debugging
Step-by-Step Solution
Solution:

  1. Step 1: Check debugger configuration

    If launch.json is missing or has errors, VS Code cannot attach the debugger properly.

  2. Step 2: Understand breakpoint behavior

    Without correct config, breakpoints won't pause execution even if set.

  3. Final Answer:

    The launch.json file is missing or misconfigured -> Option C

  4. Quick Check:

    Debugger config missing = breakpoints ignored [OK]
Quick Trick: Verify launch.json exists and is correct to enable breakpoints [OK]
Common Mistakes:
  • Blaming Node.js version without checking config
  • Assuming breakpoints need browser debugging
  • Not saving files but that usually doesn't stop breakpoints
