  • Follows best practices

Getting Started​

Basic File Creation​

  1. Open Cursor
  2. Access the agent panel
  3. Use the command: "Create a new file"
  4. Specify the file details

Example Commands​

# Create a new component
Create a new React component called Button

# Create a new API endpoint
Create a new API endpoint for user authentication

# Create a new configuration file
Create a new configuration file for the project

Advanced Usage​

File Templates​

  1. Component Template

    // Button.tsx
    import React from 'react';

    interface ButtonProps {
      text: string;
      onClick: () => void;
    }

    export const Button: React.FC<ButtonProps> = ({ text, onClick }) => {
      return (
        <button onClick={onClick}>
          {text}
        </button>
      );
    };

  2. API Endpoint Template

    // auth.ts
    import { Request, Response } from 'express';

    export const login = async (req: Request, res: Response) => {
      try {
        // Implementation
      } catch (error) {
        res.status(500).json({ error: 'Internal server error' });
      }
    };
