Run/Debug Configuration: Attach to Node.js/Chrome

Run | Edit Configurations | Add New Configuration | Attach to Node.js/Chrome


In this dialog, create configurations for debugging already running Node.js applications. This approach gives you the possibility to re-start a debugging session without re-starting the Node.js server.

Also use this configuration to debug background and additional main processes of NW.js applications, see Run/Debug Configuration: NW.js.

Before you start

Download and install Node.js.

Description

Host

In this field, specify the host where the application is running.

In this area, choose the debugging protocol to use:

Reconnect automatically

Select this checkbox to enable the PhpStorm built-in debugger to re-attach to a running Node.js process after the code of the application is changed. This lets you debug Node.js applications that use the nodemon utility, which automatically reloads your Node.js process when the code is updated. See Debugging an application that uses nodemon for details.

Remote URLs of local files

In this area, specify the remote paths for the project folders. This is helpful if the root folder of the running application is different from the name of you PhpStorm project root folder.
