Practical Case: Building a Full-Stack Application

Let's see how Antigravity works through a practical case.

Case: Creating a To-Do Application

Step 1: Describe the Requirements

Enter a natural language description in Antigravity:

Create a to-do application with the following features:
- User registration and login
- Create, edit, delete to-do items
- Mark as completed status
- Filter by priority and due date
- Responsive design, support mobile devices
Technology Stack: React + Node.js + PostgreSQL

Step 2: Agent Planning

Antigravity will automatically break down tasks and assign them to different agents:

📋 Task planning completed

🤖 Frontend Agent:
  - Create React project structure
  - Implement login/register components
  - Develop to-do list UI
  - Add responsive styles

🤖 Backend Agent:
  - Set up Express.js server
  - Implement user authentication (JWT)
  - Create to-do CRUD API
  - Configure PostgreSQL connection

🤖 Database Agent:
  - Design database schema
  - Create migration files
  - Generate seed data

🤖 Testing Agent:
  - Write unit tests
  - Create end-to-end tests
  - Set up CI/CD process

Step 3: Execution and Monitoring

Agents start working autonomously, and you can monitor progress in the dashboard:

[Frontend Agent] ✅ Project structure created
[Frontend Agent] 🔄 Implementing login component...
[Backend Agent] ✅ API endpoints created
[Backend Agent] 🔄 Configuring authentication middleware...
[Database Agent] ✅ Schema design completed
[Testing Agent] ⏳ Waiting for code completion to start testing...
