Node Inspector is a debugger interface for nodeJS using the WebKit Web Inspector.

Getting Started

Requirements

  • nodeJS
    • versions: 0.1.101 or later
  • A WebKit based browser: Chrome, Safari, OmniWeb, etc.

Install

  • With npm npm install node-inspector
  • Or from source

Debugging

As an example lets debug test/hello.js, from the root project directory (node-inspector)

  1. start the inspector in the background node-inspector &

  2. start the node instance to debug node --debug test/hello.js

  3. open http://127.0.0.1:8080 in your favorite WebKit based browser

    Chrome 5 users MUST use 127.0.0.1 NOT localhost or the browser will not connect to the debugger

  4. you should now see the javascript source from nodeJS

  5. select the hello.js script and set some breakpoints (far left line numbers)

  6. now open http://127.0.0.1:8124/ in a new tab then go back to inspector tab

  7. click "Step over next function call" and observe changes in the RHS panel

  8. then watch the screencast

For more information on getting started see the wiki

Options

    --web-port=[port]     port to host the inspector (default 8080)

Cool stuff

  • the WebKit Web Inspector debugger is a great js debugger interface, it works just as well for node
  • uses WebSockets, so no polling for breaks
  • remote debugging
  • javascript top to bottom :)
  • edit running code
  • collaborative debugging

Known Issues

This is alpha quality code, so use at your own risk:

  • be careful about viewing the contents of Buffer objects, each byte is displayed as an individual array element, for anything but tiny Buffers this will take too long to render
  • while not stopped at a breakpoint the console doesn't always behave as you might expect
  • closing the browser does not stop debugging, you must stop node-inspector manually

TODOS

  • save application settings
  • profiler panel
