It currently only works in Chrome and Opera. Node Inspector allows you to debug your app using a nice GUI debug interface inside of a browser. The built-in debugger works fine in some situations, but it takes a far back seat to Node Inspector. It occasionally hangs when inspecting especially large variables. In my experience, I’ve found the REPL to be a bit slow at times.

When you run your app in debug mode via node debug, it will break when a debugger statement is hit.Īs an example, consider the following simple Node app:įrom here, we can use the following debug commands (found in the Node debugger docs) to step through our code :Īt any point, we can open a REPL by typing repl to inspect or reassign variable values. It supports placing debugger statements in your source code. If you’ve done any Node development, you’re probably familiar with the built-in Node debugger. I wanted to get a better understanding of the debug options available for Node apps, so I thought I would do some investigation and summarize what I found. It is therefore wise to set the value to a cryptographically secure string before enabling debugging for your site.I’ve been doing a lot of Node.js development lately. As long as debugging is enabled in iisnode.yml (it is disabled by default), anyone who knows the value of the debugger path segment can interfere with your application. Note that customizing the URL path segment reserved for debugging is important for the security of your site. Once the path segment has been changed, you can navigate to the node-inspector debugger using the URL. When changing the debugger path segment, a corresponding change must be done in the URL rewrite rules in web.config. You can modify this value using the debuggerPathSegment setting in iisnode.yml, e.g.: 1 By default the value of the segment is debug, and so you navigate to the node-inspector debugger by visiting. However, you have control over the URL path segment value used for that purpose. The iisnode debugger integration requires that part of the URL space of your Windows Azure Web Site is reserved for use by node-inspector. You can read more about the node-inspector integration with iisnode here.

The URL rewrite rules in web.config can remain in place. When you have finished debugging, remember to disable the feature by setting debuggingEnabled to false in iisnode.yml. This will terminate the debugger and debugee processes in Azure.

When you are done with the debugging session or simply want to start from a clean slate, navigate to. If any of the breakpoints you set in node-inspector were hit, you should see execution paused in the browser instance running node-inspector. In a separate browser window you can invoke an endpoint in your application, e.g. This should bring up the familiar node-inspector interface for your application, which allows you to set breakpoints, inspect code, etc. To open the debugger for your application, navigate to. Assuming the entry point to your Node.js application is the server.js file, your web.config could look as follows: 1Īfter your application has been re-deployed with the changes to web.config and iisnode.yml described above, you are ready to start debugging. In web.config, you must configure URL rewriting rules which allow iisnode to distinguish HTTP requests that target the node-inspector debugger from requests that target your application. In iisnode.yml, you must enable debugging by setting the debuggingEnabled property to true: 1 We are working on streamlining this experience in future releases of Windows Azure Web Sites. To enable node-inspector debugging for Node.js apps deployed to Azure, you must currently ensure the settings in your iisnode.yml and web.config files are correct. In order to enable node-inspector debugger in Azure, a few steps need to be followed. One of the features of iisnode is integrated debugging experience based on node-inspector. Node.js applications deployed to Azure are using the iisnode module to run. This post explains how you can remotely debug your Node.js application deployed to Windows Azure Web Sites using the node-inspector debugger.
