Are you facing an issue where you can't debug your current TypeScript file in VS Code because the corresponding JavaScript file cannot be found? Don't worry, this common problem can be easily resolved with a few simple steps to ensure your debugging process runs smoothly.
When you write TypeScript code in VS Code, it gets transpiled into JavaScript code for execution. During debugging, VS Code needs the JavaScript files corresponding to your TypeScript files to map the source code correctly. If it can't find the JavaScript files, you may encounter this problem.
Here's how you can fix it:
1. Check Your tsconfig.json: Start by ensuring that your `tsconfig.json` file is correctly configured to generate the JavaScript files along with the TypeScript files. Make sure the `compilerOptions` include `"sourceMap": true` to generate source map files that link TypeScript and JavaScript code during debugging.
2. Compile Your TypeScript Code: Before debugging, run the TypeScript compiler to generate the JavaScript files. You can do this by opening the integrated terminal in VS Code and running `tsc` to compile your TypeScript code. Ensure that the compilation process completes without any errors.
3. Update Your Debug Configuration: In VS Code, go to the debug view (`Ctrl+Shift+D`) and check your debug configuration in `launch.json`. Make sure that the `outFiles` property points to the correct location of your transpiled JavaScript files. This tells VS Code where to find the JavaScript files corresponding to your TypeScript code.
4. Enable Source Maps: Ensure that source maps are enabled in VS Code. You can do this by checking the settings (File > Preferences > Settings) and searching for "source maps". Make sure the corresponding options are enabled to allow VS Code to use source maps for debugging.
5. Clear Cached JavaScript Files: Sometimes, cached JavaScript files can cause issues. Try deleting the existing JavaScript files corresponding to your TypeScript code and recompiling your TypeScript project. This can help refresh the files and allow VS Code to locate them correctly during debugging.
By following these steps, you should be able to resolve the issue of not being able to debug your TypeScript code due to missing JavaScript files in VS Code. Remember to keep your configurations in check, compile your TypeScript code correctly, and ensure that source maps are enabled for a seamless debugging experience.
With these troubleshooting tips, you can now debug your TypeScript files effectively in VS Code and overcome the hurdle of missing JavaScript files. Happy coding!
