sails debug

Attach the node debugger and lift the sails app; similar to running node --debug app.js. Takes the same options as sails lift. You can then use node-inspector to debug your app as it runs.

Example

$ sails debug

info: Running node-inspector on this app...
info: If you don't know what to do next, type `help`

debugger listening on port 5858

To use the standard (command-line) node debugger with sails, you can always just run node debug app.js.

Using node-inspector

To debug your Sails app using node-inspector, first install it over npm

$ npm install -g node-inspector

Then, launch it with the node-inspector command

$ node-inspector

Now, you can lift your Sails app in debug mode

$ sails debug

Once the application is launched, visit http://127.0.0.1:8080?port=5858 in Opera or Chrome (sorry, other browsers!). Now you can request your app as usual on port 1337 and debug your code from the browser.

How it works Node.js includes a TCP-based debugger. When you start your application using sails debug, Node.js lifts your app and opens a socket on port 5858. This socket allows external tools to interact with and control the debugger. Node-inspector, accessible via the port 8080, is this kind of tool.

If you don't see your files in the browser at http://127.0.0.1:8080?port=5858 or if it's very slow to load, try to run node-inspector with the --no-preload argument. See the node-inspector repo for more details
