You can also open and explore profiles and snapshots captured in Google Chrome’s DevTools for the client-side JavaScript app or previously captured in WebStorm for Node.js app. You will see a new tool window with the snapshot analysis results. Once you’ve started your configuration, click the Take Heap Snapshot icon on the Run or Debug tool window control panel. Please install and specify the path to Node.js v8-profiler (run npm install -g v8-profiler), as required for snapshot processing. To start memory profiling, select Allow talking heap snapshots in the Node.js run configuration. We’ll do a follow-up post with a more detailed overview of the tool. You can look through the call trees and other results in the profiling tool window. Run the configuration, execute the scenario that you would like to profile, and then stop the process. Specify the paths to the tick module and Gnuplot executable in the configuration and you’re ready to go. If you want to explore a timeline view that shows where V8 is spending time, you also need to install Gnuplot (we recommend using apt-get on Linux and Homebrew on Mac for Gnuplot installation, so that all the required dependencies are installed as well). To process the profiling log files, WebStorm needs the help of a third-party Node.js module called tick, which can be installed via npm (run npm install -g tick). In the Node.js Run configuration, go to V8 profiling tab and enable CPU profiling. With V8 CPU profiling you can 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. This post will help you get started with V8 profiling in WebStorm later we’ll publish a more detailed guide. You can also open and explore heap snapshots captured in Google Chrome’s DevTools for your client-side code. Please meet a new V8 profiling feature that allows you to capture and analyze CPU profiles and heap snapshots for your Node.js applications. JavaScript support improvements, distraction free mode, simultaneous HTML tag editing.Read about other new features that we’ve added in WebStorm 10 EAP: If you experience any issues, please report them to our tracker. In other great news, support is now available for the new TypeScript 1.4 features: Union Types, Type Guards, Let and Const keywords, Template strings, and more.įor the full list of addressed issues, see the release notes. While we continue improving JavaScript support and performance, we want to introduce two great new features: V8 CPU and memory profiling for Node.js applications, and a built-in TypeScript compiler. An update from the previous EAP build is available, however, you may need to manually restart the IDE after the update. You can download it and install side-by-side with WebStorm 9. The new Early Access build for WebStorm 10 (140.2753) is now available for trying.
