![]() ![]() Debug a TypeScript application running on an external web server ![]() If your application is running on the built-in WebStorm server, refer to Running a client-side TypeScript application above, you can also debug it in the same way as JavaScript running on the built-in server. Click the icon that indicates the desired browser.ĭebug a client-side TypeScript application Hover over the code to show the browser icons bar. Then select the desired browser from the list. This HTML file does not necessarily have to be the one that implements the starting page of the application.Ĭhoose View | Open in Browser from the main menu or press Alt F2. In the editor, open the HTML file with a reference to the generated JavaScript file. The only difference is that you can set breakpoints right in the TypeScript code.Ĭompile the TypeScript code into JavaScript. You can write a client-side application in TypeScript, compile the code as described in Compiling TypeScript into JavaScript, and then run and debug your application exactly in the same way as client-side applications written in JavaScript. As a result, you can set breakpoints in your TypeScript code, launch the application with the run/debug configuration of the type JavaScript Debug (for client-side code) or Node.js, and then step through your original TypeScript code, thanks to generated sourcemaps. You can do that using the built-in TypeScript compiler and other tools, including ts-node for running TypeScript with Node.js, used separately or as part of build process.ĭuring compilation, there can also be generated source maps that set correspondence between your TypeScript code and the JavaScript code that is actually executed. With WebStorm, you can run and debug client-side TypeScript code and TypeScript code running in Node.js.ĭebugging of TypeScript client-side code is only supported in Google Chrome and in other Chromium-based browsers.įor more information about running and debugging TypeScript with Angular, refer to Running and debugging Angular applications.īefore running or debugging an application, you need to compile your TypeScript code into JavaScript. ![]()
