Debugging Node

Errors

Types of Errors

Syntax Errors

you get an error message and just have to find the error

Runtime Errors

code doesn't run

Logical Errors

no Error message, can be hard to find

Debugger

in VS Code:

run>debug

-> choose node.js

set breakpoints

• you can run code in the debug-console (like in dev-tools), eg.
• you can change values of variables in the debugger

parsedBody.split('=')

auto-restart debugger

run> add configuration

-> edit launch.json

add

"restart": true,
"runtimeExecutable": "nodemon",
"console": "integratedTerminal"

-> this needs nodemon to be installed globally
