Then select the relevant V8 log file isolate. To open and analyze some previously saved profiling data, go to Help | Find Action (or press Control+Shift+A), start typing V8, and select Analyze V8 Profiling Log from the list.
Tabs that were opened automatically are named after the run configurations that control execution of the applications and collecting the profiling data. If the window is already open and shows the collected data for another session, WebStorm opens a new tab. When you stop your application, WebStorm automatically opens the V8 Profiling tool window and shows the collected profiling data in it. When the scenario that you need to profile is executed, stop the process by clicking on the toolbar. Select the run configuration from the list on the main toolbar and click or select Run | Run from the main menu. In the Log folder field, specify the path to the folder where the recorded logs will be stored, log files are named isolate. Switch to the V8 Profiling tab and select the Record CPU profiling info checkbox. In the Edit Configurations dialog that opens, click the Add button ( ) on the toolbar and select Node.js from the list.įrom the list, select the Node.js run configuration to activate CPU Profiling in or create a new configuration as described in Running and debugging Node.js. Alternatively, select Edit Configurations from the list on the toolbar. To invoke V8 CPU profiling on application start, you need to specify additional settings in the Node.js run configuration.įrom the main menu, select Run | Edit Configurations. Measurements are made not only for the work of your code, but also for the activities performed by the engine itself, such as compilation, calls of system libraries, optimization, and garbage collection. The profiler takes snapshots at certain intervals that are called ticks.

Node.js CPU profiling in WebStorm is based on the V8 built-in CPU profiler, which provides information about the execution of your code and the behavior of the JavaScript engine itself including garbage collection cycles, compilation and re-compilation, and code optimization. For more details about plugins, see Managing plugins.ĬPU profiling helps you get a better understanding of which parts of your code take up the most CPU time, and how your code is executed and optimized by the V8 JavaScript engine. Press Control+Alt+S to open the IDE settings and then select Plugins. Make sure the Node.js plugin is enabled in the settings. You can also open and explore snapshots captured in Google Chrome DevTools for your client-side code. The IDE will be restarted with the default configuration.With WebStorm, you can capture and analyze CPU profiles and heap snapshots for your Node.js applications using V8’s sample-based profiler. In the confirmation popup that opens, click Restore and Restart. Back up your settings and restore the defaultsįrom the main menu, select File | Manage IDE Settings | Restore Default Settings.Īlternatively, press Shift twice and type Restore default settings.
You can always restore your settings from that backup. When you restore the default IDE settings, WebStorm backs up your configuration to another directory.
Settings that are NOT marked with the icon in the Settings dialog are global and apply to all existing projects of the current WebStorm version. Alternatively, press Control+Alt+S or click on the toolbar.

To configure your IDE, select File | Settings for Windows and Linux or IntelliJ IDEA | Settings for macOS. Such settings include IDE appearance (themes, color schemes, menus and toolbars), notification settings, the set of the installed and enabled plugins, debugger settings, code completion, and so on. Global settings apply to all projects of a specific installation, or version, of WebStorm. WebStorm allows you to configure the settings for specific projects or globally. Settings are preferences related to resources, file colors, version control options, code styles, and so on.
