Set the breakpoints in the code where necessary.Ĭreate a Node.js run/debug configuration as described above. Starting the debugger together with a Node.js application on your computer To debug a running application, use an Attach to Node.js/Chrome configuration. JetBrains Rider recognizes -inspect, -inspect-brk, and now deprecated -debug flags so you can make any application accessible for debugging. In this case, your application is already running in the debug mode and JetBrains Rider attaches to a running process. Start the debugger together with your application using a Node.js run/debug configuration.Īttach the debugger to an already running application. You can initiate a debugging session in two ways: In the Debug tool window, you can view the call stack and the variables in their current state, evaluate expressions in the editor, and step through the code. You can do many things that will help you explore the code and understand where the bug is. You can put breakpoints right in your JavaScript or TypeScript code so you no longer need any debugger and console.log() statements. JetBrains Rider makes it easier to debug Node.js applications. To enable saving the Process Console output to a log file, select the Save console output to file checkbox and specify the file location.Ĭhoose when you want the Process Console shown. To skip the previous content, select the Skip Content checkbox.

Select the Is Active checkbox next to it. Select whether you want to show all files that this pattern covers or only the last one.Ĭlick OK to return to Node.js Run/Debug Configuration dialog, where the new log file is added to the list. In the Edit Log Files Aliases dialog that opens, type the alias name to show in the list of log entries and specify the location of the log file.

Manage logs when running a Node.js applicationĬreate a Node.js run/debug configuration as described above and go to the Logs tab.Ĭlick next to the Log files to be shown in console field which lists the available log files (if any). If you are using a logging tool like morgan in your application and this tool writes logs to a file, you can see these logs in the Console tab of the Run tool window. The application starts, and the Run window opens showing the application output. Select the newly created Node.js configuration from the Select run/debug configuration list on the toolbar and click next to the list. In the dialog that opens, specify the URL of the application starting page, for example, localhost:3000 for Express applications, and the browser to use. Click to expand the Before launch area, click, and select Launch Web Browser from the list. To open the application in the browser automatically, configure a before-launch task. In the Application parameters field, specify the Node.js-specific arguments to be passed to the application on start through the process.argv array. For example, you may want to enable an experimental Node.js feature or pass another option, see the Node.js official website for details. Specify the Node Parameters that customize the start of Node.js. In the JavaScript File field, specify the path to the main file of the application that starts it (for example, bin/www for Express applications). This can be a local Node.js interpreter or a Node.js on Windows Subsystem for Linux. The Run/Debug Configuration: Node.js dialog opens. In the Edit Configurations dialog that opens, click on the toolbar and select Node.js from the list. Alternatively, select Edit Configurations from the list on the toolbar.

Create a Node.js run/debug configurationįrom the main menu, select Run | Edit Configurations. JetBrains Rider also uses this configuration to start the debugger together with Node.js applications. JetBrains Rider runs Node.js applications according to a run configuration of the type Node.js. Make sure the Node.js plugin is enabled on the Settings/Preferences | Plugins page, tab Installed. You can debug applications that are started from JetBrains Rider as well as attach to already running applications. JetBrains Rider helps you run and debug your Node.js applications.
