How To Debug Vue Js In Visual Studio Code

If you are developing a Vue js application, it is always important to debug and identify errors. Debugging can be a daunting task, but with the help of Visual Studio Code, it can be made easier. In this article, we will discuss how to debug Vue js in Visual Studio Code.

Setting Up The Environment

Before we get started with debugging, we need to set up our environment. The first thing you need is to install Visual Studio Code. Once you have installed Visual Studio Code, you need to install the Vue.js extension. You can do this by navigating to the extensions section in Visual Studio Code and searching for ‘Vue.js Extension Pack’. Once you find it, install it.

Debugging Vue js Code

With the environment set up, we can now start debugging our Vue js code. First, open your Vue js project in Visual Studio Code. Navigate to the Debug panel on the left-hand side of the editor. You may need to click on the ‘Run and Debug’ button before the Debug panel appears.

Setting Breakpoints

The first step in debugging your Vue js code is setting breakpoints. Breakpoints tell the debugger where to pause the execution of your code. You can set a breakpoint by clicking on the left-hand side of the code editor, next to the line of code you want to pause at. Once you have set a breakpoint, run your Vue js application using the ‘F5’ key.

Stepping Through The Code

Now that you have set a breakpoint, you can step through your code. Click on the ‘Step Over’ button in the Debug panel to execute the current line of code and move to the next line. You can also use the ‘Step Into’ button to move into a function call.

Debugging Errors

If your Vue js application encounters an error, the debugger will automatically stop at the line of code where the error occurred. The Debug panel will display the error message, and you can inspect variables and values to help you identify the cause of the error.

Conclusion

Debugging Vue js in Visual Studio Code is a powerful tool that can help you identify errors and improve the quality of your code. By using breakpoints and stepping through your code, you can quickly identify issues and fix them. Remember to always test your code thoroughly to ensure it works as expected.
