#Brackets Node.JS Debugger

Brackets-node-debugger is an extension for the Brackets editor.

It's an early stage step-by-step debugger for Node.js applications.

Install it

Use the built-in Brackets Extension Manager to install Node.JS Debugger or clone this repository into your Extension folder

You need to restart (not just reload) Brackets after the installation!

How to use it

Start your script with node --debug-brk yor-script.js or node --debug your-script.js

Go into Brackets and click on Debug -> Node.js Debugger or use Ctrl-Shift-I

Click on the red icon at the top left corner to activate the debugger and connect it to your script.


Use the Buttons to Step over, Step in, Step out or to continue the script execution.


Click on a line number to set/remove a Breakpoint and use the console to get an variable for the current scope.


Use the arrow keys to browse through the history.


Open the preferences file (brackets.json) and edit/add the entry. All options use the brackets-node-debugger.-prefix

Option Default Description
debugger-port 5858 Port the V8 Debugger is running on
debugger-host localhost Host the V8 Debugger is running on
