Debug Vue Js Visual Studio Code

Vue Js is a progressive JavaScript framework used to build user interfaces. It’s widely popular among the developer community due to its simple syntax, minimalistic approach to code organisation and state management techniques. Although it has gained a lot of traction over the past few years, developers often encounter problems while debugging their Vue.js projects. In this article, we’ll discuss how to debug Vue Js in Visual Studio Code.

The Role of Visual Studio Code in Vue Js Debugging

Visual Studio Code is a popular code editor that comes with a built-in debugger. It can easily be configured to work with Vue.js by installing the Vue.js extension. Visual Studio Code’s debugger can help developers set breakpoints, step through code, and inspect variables during runtime. This helps developers quickly identify and fix problems in their Vue.js projects.

Setting Up Visual Studio Code for Vue Js Debugging

Step 1: Install Visual Studio Code

Visual Studio Code can be downloaded for free from the official website. Once downloaded, install the editor on your system.

Step 2: Install Vue.js Extension

Open Visual Studio Code, and navigate to the Extensions section in the sidebar. Search for the extension named “Vue.js Extension Pack” and install it.

Step 3: Create a Vue.js Project

Create a new Vue.js project or use an existing one. Open the project in Visual Studio Code.

Step 4: Configure Visual Studio Code for Debugging

  1. Open the Debug panel in Visual Studio Code
  2. Click on the “create a launch.json file” option
  3. Select the “Chrome” option as the Debugger
  4. Save the launch.json file

Step 5: Add Breakpoints to Code

With Visual Studio Code set up for Vue.js debugging, developers can add breakpoints to their code by clicking on the line number in the editor. Breakpoints can also be added by right-clicking on the line number and selecting “Add Breakpoint”.

Debugging Vue.js in Visual Studio Code

Once the breakpoint has been added, running the project in debug mode will cause the program to pause at the breakpoint. Developers can then examine the variables and step through the code to identify and fix any issues. Variables can be examined using the Debug Console in Visual Studio Code.

Conclusion

Debugging Vue Js in Visual Studio Code is a powerful and efficient way to identify and fix any issues in a Vue.js project. By following the steps outlined in this article, developers can quickly set up their environment for debugging and use the tools provided by Visual Studio Code to streamline their development process.
