To debug different types of apps and files, you need to use different types of run/debug configurations.ĭepending on the type, the information you need to provide in the configuration varies.įor example, in the Node.js configuration, you need to specify a file that needs to be run. Run/debug configuration is an entry point to, as the name suggests, running and debugging apps in WebStorm. Prepare for debugging: create a run/debug configuration Then we’ll put in some breakpoints, see what’s going on in the Debugger’s Variables view, step through the code, evaluate expressions and use the interactive console. We’ll start with creating a new run/debug configuration. To see how the debugger works in WebStorm, we’ll try to debug a simple Express Node.js application. If you want to edit the code or quickly navigate to the usages or definitions of methods while debugging, you don’t need to switch back to the editor.Īnd no matter what kind of code you debug, your experience with the debugger will be the same. One of the main benefits of using a debugger inside the IDE is that you put the breakpoints and step through your actual source code (even if you then compile it. ![]() In addition to that, you can also debug unit tests and build scripts. With WebStorm you can debug all kinds of applications written in JavaScript, TypeScript or Dart: Node.js, React Native and Electron apps and, of course, client-side apps written using different frameworks. You can find the full list of the issues addressed in WebStorm 2018.1.2 in the Release Notes.The debugger is one of the most essential features of WebStorm. You will now get more precise code completion for JavaScript object properties after you explicitly check that they exist: At the moment this option is on to keep the current behavior. You can now disable adding types in these comments in Preferences | Editor | Code Style | TypeScript – Generated code – Include types in JSDoc. In the TypeScript code, WebStorm by default adds the type info to this comment. If you type /** before the function and press Enter, WebStorm will automatically generate a JSDoc comment for it. Please note that right now enabling this option may slow down the initial page load. The new option provides a more general solution. In the past years, we’ve implemented a bunch of workarounds that helped to detect and stop on these breakpoints in some specific cases. ![]() The reason why it happens is that the code under the breakpoint is executed before WebStorm connects to Chrome and gets the source maps to check the breakpoints in the original source. This option should solve the problem with some breakpoints that are in the code that is executed on page load not being hit before you reload the page in the browser. In the JavaScript debug configuration we’ve added a new option Ensure breakpoints are detected when loading scripts. To make WebStorm follow these new rules when adding imports, please go to Preferences | Editor | Code Style | TypeScript – Imports and remove rxjs from the Do not import exactly from list.Īnd for the RxJS operators, WebStorm will automatically use the correct import paths 'rxjs/operators'. For example, instead of import from 'rxjs'. RxJS 6 changes the way you should import its types. Moreover, WebStorm has changed all the imports and usages of this component in other templates. ![]() Notice how the filenames and the paths to them have changed. Now if you rename a class ( Refactor – Rename in the context menu or F6) that defines an Angular component, WebStorm will automatically suggest that you rename all the related files and their usages. ![]() The Angular Style Guide recommends using the same name for the component’s class and its TypeScript, template and style files. There is more about some of the improvements below. Replace with the template string intention now works correctly for expressions with the ternary operator ( WEB-24100).The new React 16.3 lifecycle methods are now resolved and are available in code completion suggestions when is installed ( WEB-32069).The log messages are again now shown in the Console tab of the npm, Gulp, and Grunt tool windows ( WEB-32003).More precise code completion for object properties after you explicitly check that they exist.The new option in the TypeScript code style settings allows omitting types in the generated JSDoc comments.With the new option in the JavaScript debug configuration, the breakpoints in the code that is executed on page load are hit on the first app run.Auto import for the RxJS operators now respects the new import style introduced in RxJS 6.0.When renaming an Angular component, you can now automatically rename the related.In WebStorm 2018.1, please use Check for Updates… in the WebStorm menu on macOS or by using the Help menu on Windows and Linux to update to WebStorm 2018.1.2. Please update using Toolbox App or the IDE or download WebStorm 2018.1.2 from our website.
