Claude 3.5 Sonnet VS Code Extension Tutorial: AI-Powered Coding Assistant ??

Introduction

Hello, and welcome to this tutorial on using the Claude 3.5 Sonnet agentic coding tool in Visual Studio Code (VS Code). In this article, we’ll walk through the installation and usage of the Claude Dev extension, which utilizes AI to streamline your coding process. By the end of this guide, you’ll be equipped to leverage this extension to enhance your coding projects.

Installation of Claude Dev

To begin using Claude, first, you need to set up the extension in VS Code. Follow these steps:

1. Get Your API Key: You will need an API key from Anthropic, which you can obtain by visiting their website (anthropic.com).

2. Install the Extension:

   • Open Visual Studio Code.
   • Go to Extensions (you can find it in the sidebar).
   • Search for "Claude" and find the Claude Dev extension.
   • Click install.

3. Set Up Your API Key:

   • After installation, click on the Claude Dev icon.
   • You will be prompted to enter your Anthropic API key. Input the key you received earlier and confirm.

Once you have completed these steps, Claude will be ready for action, enabling you to leverage its coding capabilities.

Using Claude to Create a Tic-Tac-Toe Game

Let’s start with a hands-on example. We will create a simple JavaScript, HTML, and CSS game of Tic-Tac-Toe.

1. Initiate Your Project: Create a new folder in your workspace called "TicTacToe".

2. Task Request: Request Claude to create the files necessary for the game (index.html, style.css, script.js). You can do this by typing the request in Claude, and it will initiate an API call.

3. Approve Changes: Claude will use its diff engine to present you with the differences between the original empty files and the proposed changes. Approve each of the requests to create the new files with their respective content.

4. Run Your Project: Once the necessary files are created, you can open the game in a browser and start playing.

Adding Features with Claude

To enhance our Tic-Tac-Toe game, let’s add a scoreboard to keep track of players' wins and include a master reset function.

1. Feature Request: Ask Claude to include a scoring feature by typing a new request.

2. Review and Approve: Claude will once again show the necessary changes using the diff engine. You will need to approve the changes for the HTML, CSS, and JavaScript files.

3. Run the Updated Game: After approving the modifications, run the game again and check the new scoreboard functionality.

Creating a Snake Game in Python

In addition to the Tic-Tac-Toe game, let's test Claude’s capabilities by creating a Snake game in Python.

1. Project Creation: Request Claude to create a new folder and necessary files (HTML, CSS, and Python files) for the Snake game.

2. Code Review and Approval: Follow a similar process with the diff engine to approve code changes.

3. Check Functionality: When you run the game, you may need to troubleshoot issues such as missing package installations (for example, libraries required for graphical rendering).

Conclusion

The Claude 3.5 Sonnet coding assistant is a powerful tool for developers looking to speed up their coding tasks. It simplifies the process of generating code and testing applications, providing a good starting point for various projects. However, it is essential to review and test any generated code to ensure it meets production standards.
