Please share information about your IDE version and breakpoint locations and, if possible, your project. If you have any problems with debugging your application, please contact our support team. As a workaround, you can reload the page in the browser. The reason for this is that the IDE needs to get the source maps from the browsers to be able to stop on a breakpoint you’ve placed in the original source, and that only happens after the page has been fully loaded at least once. The breakpoints put in the code and executed on page load might not be hit when you open an app under a debug session for the first time. You can learn more about this from Examine suspended program and Step through the program docs. Once a breakpoint is hit, WebStorm opens the Debug tool window where you can explore the call stack and variables, step through the code, set watchers, evaluate variables, and do all the other things that you can normally do when debugging. Of course, you can also select the Angular Application run/debug configuration from the list on the toolbar and click the Debug button next to the list of configurations in the top right corner of the IDE. WebStorm launches the auto generated Angular Application run/debug configuration, the browser opens at and the Debug tool window appears showing you the call stack and variables. You can now start debugging the client-side TypeScript code of your app right from the Run tool window! Just hold Ctrl+Shift / ⌘⇧ and click the URL address where the application is running. When the app is compiled and the Webpack dev server is ready, the Run tool window shows that the app is running in the browser at Note that when the dev server is running, the app will automatically reload if you change any of the source files. In either case, WebStorm launches the predefined Angular CLI Server run/debug configuration. Select the Run Angular CLI Server run/debug configuration from the list on the toolbar and click the Run button next to the list. Open your package.json file, click the Run Script gutter icon next to the start script, and select Run Angular CLI Server from the list. Open the built-in Terminal and type npm run start.ĭouble-click the start task in the npm tool window. To set a line breakpoint, click the gutter next to the executable line of code where you want the application to suspend. The function receives target options and original index.html content (generated by Angular CLI), and returns a new content as a string or a Promise: In the above example, we’re using cheerio to update the HTML. ts file, that exports a transformation function for index.html. WebStorm recognizes line breakpoints, exception breakpoints, and conditional breakpoints. indexTransform is a path (relative to the workspace root) to a. You do not need to define any run/debug configurations yourself, as WebStorm has already created two default ones for you:Īngular CLI Server to launch your app in the development mode. Learn more from Creating a new Angular application. When you click Create, WebStorm downloads and runs Angular CLI, which generates an app with an Angular-specific structure, and downloads all the required dependencies. Select File | New Project from the main menu, then, in the New Project dialog, select Angular CLI as the project type, and specify the application name (blogAngular) and parent folder for it (WS). With WebStorm, you don’t have to download Angular CLI in advance – during project generation the IDE downloads and runs it using npx. The same principles apply to our other IDEs, including IntelliJ IDEA, PhpStorm, and P圜harm. If you have never used the JavaScript debugger in WebStorm before, we recommend watching this video first to learn how to get started.
