Antigravity Manager Developer Guide

🏗️ Architecture Overview

Antigravity Manager is a hybrid Desktop Application built with Electron, React, and NestJS. It follows a modular architecture where the frontend (Renderer) communicates with the backend (Main) via type-safe IPC (ORPC).

Key Technologies

  • Frontend: React 19, TailwindCSS v4, TanStack Router, TanStack Query.
  • Backend: Electron (Main), NestJS (Core Logic), Better-SQLite3 (Data).
  • Communication: ORPC (Type-safe IPC wrapper around Electron IPC).
  • Build: Electron Forge + Vite.

📂 Directory Structure

  • src/main.ts: Electron Main Process entry point.
  • src/preload.ts: Bridge between Main and Renderer.
  • src/renderer.tsx: React App entry point.
  • src/components/: Reusable React UI components (Radix UI based).
  • src/ipc/: IPC Routers and Handlers (Domain logic).
    • router.ts: Main ORPC router definition.
    • account/, cloud/, database/: Domain-specific handlers.
  • src/server/: NestJS application modules (proxies/gateways).
  • src/services/: Core business logic (framework agnostic).
    • GoogleAPIService.ts: Gemini/Cloud interactions.
    • AutoSwitchService.ts: Account rotation logic.
  • src/routes/: Frontend routing definitions (File-based).

🚀 Development Workflow

Prerequisites

  • Node.js 18+
  • npm (Project uses package-lock.json)

Common Commands

  • Start Dev Server: npm start
  • Lint Code: npm run lint
  • Unit Test: npm run test:unit
  • E2E Test: npm run test:e2e
  • Build Production: npm run make

🧠 Core Concepts

IPC Communication (ORPC)

The project uses orpc for type-safe communication.

  • Define: Create a router in src/ipc/router.ts with Zod schemas.
  • Implement: Add logic in handlers (e.g., src/ipc/account/handler.ts).
  • Call: Use the generated client in React components.

Database Access

Data is stored in a local SQLite file.

  • Use Better-SQLite3 for direct access.
  • Logic should be encapsulated in src/services or src/ipc.

Account Management

  • Accounts are added via OAuth (Google/Claude).
  • GoogleAPIService handles token exchange and refreshing.
  • AutoSwitchService monitors usage and switches active accounts automatically.

⚠️ Critical Rules

  1. Type Safety: strict TypeScript usage; Zod for runtime validation.
  2. Components: Use src/components/ui (Radix primitives) for consistency.
  3. Async: Handle all IPC/DB calls asynchronously with try/catch.
  4. Security: Never commit secrets. API keys are user-provided or encrypted locally.
