How to Use Cursor for Code Completion in 30 Minutes

If you're a solo founder or side project builder, you know how time-consuming coding can be. Typing out every line of code is not just tedious; it can also slow down your development process. That's where Cursor comes in. As a powerful AI coding assistant, Cursor can help you speed up your coding with intelligent code completion. In this guide, I’ll show you how to set it up and get started in just 30 minutes.

Prerequisites: What You Need

Before diving in, make sure you have the following:

• A code editor: Cursor works best with Visual Studio Code (VSCode) or JetBrains IDEs.
• A Cursor account: Sign up at Cursor's website.
• Basic familiarity with coding: This isn’t a beginner programming course, so some coding knowledge will help.

Step-by-Step Setup

Step 1: Install Cursor

1. Go to the Cursor downloads page.
2. Choose your platform (Windows, macOS, or Linux) and download the installer.
3. Run the installer and follow the prompts to complete the installation.

Step 2: Configure Your Code Editor

1. For VSCode:

   • Launch VSCode.
   • Go to Extensions (Ctrl+Shift+X).
   • Search for "Cursor" and install the extension.

2. For JetBrains IDEs:

   • Open your IDE.
   • Navigate to Plugins > Marketplace.
   • Search for "Cursor" and click Install.

Step 3: Connect Your Account

1. Open the Cursor extension in your code editor.
2. Log in with your Cursor account credentials.
3. Grant any necessary permissions for the extension to access your code.

Step 4: Start Coding with Cursor

Now that you’re set up, let’s get into the nitty-gritty of using Cursor for code completion.

1. Open a project in your code editor.
2. Start typing a function or variable name; Cursor will suggest completions.
3. Use the arrow keys to navigate through suggestions and hit Enter to select one.

Step 5: Explore Advanced Features

Cursor also offers some advanced features that can further enhance your coding experience:

• Context-aware suggestions: Cursor adapts to your coding style and the context of your code.
• Multi-line completions: Get suggestions for entire code blocks, not just single lines.
• Error detection: Cursor can identify potential bugs in real-time.

Troubleshooting Common Issues

• Suggestions not appearing: Make sure you’re connected to the internet and logged into your Cursor account.
• Slow performance: If Cursor is lagging, check your system resources. Closing unnecessary applications can help.

What’s Next?

Once you’ve set up Cursor, consider these next steps:

• Explore more coding projects: As you become comfortable with Cursor, take on more complex projects to fully leverage its capabilities.
• Integrate with version control: Use Git along with Cursor for a more robust development experience.
• Experiment with other AI coding tools: While Cursor is solid, it’s good to know what else is out there.

Conclusion: Start Here

If you're looking to speed up your development process, Cursor is a practical choice for code completion. Setting it up takes only 30 minutes, and you'll find that it can significantly reduce the time you spend typing out code. Start with the steps outlined above, and you'll be coding smarter in no time.

What We Actually Use

In our experience at Built This Week, we primarily use Cursor for code completion in our projects. Its intelligent suggestions save us time, especially when we're shipping new features quickly. We’ve also tried alternatives like GitHub Copilot and Tabnine, but we keep coming back to Cursor for its ease of use and integration.
