How to debug Angular 16 in Visual Studio Code

Debugging an Angular 16 application in Visual Studio Code is a common task for developers. Visual Studio Code provides a powerful debugging environment for Angular applications, allowing you to find and fix issues in your code more efficiently.

Here are the steps to debug an Angular 16 application in Visual Studio Code:

1. Open your Angular project in Visual Studio Code. If you haven’t already done so, you can open your project by clicking on “File” > “Open Folder” in Visual Studio Code and selecting your project folder.

2. Once your project is open in Visual Studio Code, you can start the debugging process by clicking on the “Debug” icon on the Activity Bar on the side of the window.

3. In the Debug view, click on the gear icon and select “Add Configuration”. Choose “Node.js” from the list of available debug configurations.

4. In the newly created launch.json file, add a new configuration for debugging Angular 16. You can use the following configuration as a starting point:

{
“type”: “node”,
“request”: “launch”,
“name”: “Angular 16 debug”,
“program”: “${workspaceFolder}/node_modules/@angular/cli/bin/ng”,
“args”: [
“serve”,
“–open”,
“–port”,
“4200”,
“–configuration”,
“development”
],
“sourceMaps”: true,
“outFiles”: [
“${workspaceFolder}/dist/out-tsc/**/*.js”
]
}

This configuration will allow you to launch the Angular development server with debugging enabled.

5. Once you have added the debug configuration, you can start the Angular development server with debugging by clicking on the green “Play” button in the Debug view.

6. After the server has started, you can navigate to your Angular application in a web browser. You can then set breakpoints in your Angular code by clicking on the line number in the editor in Visual Studio Code.

7. When the execution reaches a breakpoint, you can inspect the values of variables and expressions in the Debug Console in Visual Studio Code. This will help you to identify and fix any issues in your Angular code.

By following these steps, you can effectively debug your Angular 16 application in Visual Studio Code, allowing you to improve the quality and reliability of your code.

Happy debugging!
