Simple Summary

Create a stunning CSS gradient generator with live preview functionality, allowing users to easily design and visualize custom gradients for their web projects.

Product Requirements Document (PRD)

Goals:

  • Develop a user-friendly CSS gradient generator
  • Implement real-time preview functionality
  • Provide a wide range of gradient options and customization features

Target Audience:

  • Web designers
  • Front-end developers
  • UI/UX designers

Key Features:

  1. Intuitive gradient creation interface
  2. Real-time preview of generated gradients
  3. Multiple gradient types (linear, radial, conic)
  4. Color picker with hex, RGB, and HSL support
  5. Adjustable gradient direction and angle
  6. Copy-to-clipboard functionality for generated CSS code
  7. Preset gradient templates
  8. Gradient history and favorites

User Requirements:

  • Easy-to-use interface for creating gradients
  • Ability to fine-tune gradient properties
  • Instant visual feedback on gradient changes
  • Export options for generated CSS code
  • Responsive design for use on various devices

User Flows

  1. Create a Custom Gradient:

    • User selects gradient type (linear, radial, conic)
    • User adds color stops using color picker
    • User adjusts gradient direction/angle
    • User views real-time preview of gradient
    • User copies generated CSS code

  2. Use Preset Templates:

    • User browses preset gradient templates
    • User selects a template
    • User customizes template (optional)
    • User applies template to preview
    • User copies generated CSS code

  3. Save and Manage Favorites:

    • User creates a custom gradient
    • User clicks "Save to Favorites"
    • User views saved gradients in Favorites section
    • User loads a saved gradient for editing
    • User deletes unwanted saved gradients

Technical Specifications

Frontend:

  • React.js for building the user interface
  • CSS Modules for styling components
  • Redux for state management
  • react-color for color picker functionality

Backend:

  • Node.js with Express.js for API endpoints (if needed for saving/sharing gradients)
  • MongoDB for storing user data and saved gradients (if implementing user accounts)

Tools and Libraries:

  • Webpack for bundling and build process
  • Babel for JavaScript transpilation
  • ESLint and Prettier for code linting and formatting
  • Jest and React Testing Library for unit and integration testing

API Endpoints

  1. GET /api/presets - Retrieve preset gradient templates
  2. POST /api/gradients - Save a custom gradient (if implementing user accounts)
  3. GET /api/gradients - Retrieve user's saved gradients (if implementing user accounts)
  4. DELETE /api/gradients/:id - Delete a saved gradient (if implementing user accounts)

Database Schema

Gradient:

  • id: ObjectId
  • userId: ObjectId (reference to User, if implementing user accounts)
  • type: String (linear, radial, conic)
  • colors: Array of Objects (color stops)
  • angle: Number (for linear gradients)
  • position: Object (for radial/conic gradients)
  • createdAt: Date
  • updatedAt: Date

User (if implementing user accounts):

  • id: ObjectId
  • username: String
  • email: String
  • password: String (hashed)
  • createdAt: Date
  • updatedAt: Date

Implementation Plan

  1. Set up project structure and development environment
  2. Implement basic UI components (GradientEditor, ColorPicker)
  3. Develop gradient generation logic and real-time preview functionality
  4. Implement CSS code generation and copy-to-clipboard feature
  5. Add support for different gradient types (linear, radial, conic)
  6. Develop preset templates feature
  7. Implement gradient history and favorites functionality
  8. Add responsive design and cross-browser compatibility
  9. Perform thorough testing (unit, integration, and user acceptance)
  10. Optimize performance and accessibility
  11. Prepare documentation and user guide
  12. Deploy to production environment

Deployment Strategy

  1. Set up version control with Git and GitHub
  2. Configure CI/CD pipeline using GitHub Actions or similar tool
  3. Use a static site hosting service like Netlify or Vercel for frontend deployment
  4. If backend is needed, deploy to a cloud platform like Heroku or DigitalOcean
  5. Set up monitoring and error tracking (e.g., Sentry)
  6. Implement automated backups for database (if applicable)
  7. Use a CDN for improved global performance
  8. Configure proper security measures (HTTPS, CSP, etc.)

Design Rationale

The project focuses on creating a user-friendly and efficient CSS gradient generator with real-time preview capabilities. React.js was chosen for its component-based architecture and efficient rendering, which is crucial for the real-time preview feature. The use of Redux for state management ensures a predictable state across the application, especially important for managing complex gradient configurations.

The file structure is organized to promote modularity and ease of maintenance, with separate directories for components, pages, and utilities. The implementation plan prioritizes core functionality first, followed by additional features and optimizations. The deployment strategy emphasizes automation and scalability, ensuring a smooth transition from development to production.
