-# TaylorDB React Starter
+# TaylorDB + tRPC Full-Stack Monorepo

-React + Vite starter with Tailwind CSS (v4), React Router v6, and shadcn/ui wired up for building custom UIs on TaylorDB.
+A production-ready pnpm monorepo combining React frontend and Express backend with tRPC for type-safe API communication. Built for AI-assisted development platforms.

-## What's included
- React Router layout with sample pages (`/`, `/about`, fallback `*`)
- Tailwind v4 configured for shadcn (design tokens, dark mode, animations)
- shadcn/ui baseline components: `button`, `card`, `input`, `label`, `textarea`, `select`, `tabs`, `alert`
- Path aliases via `@` (`@/components`, `@/lib`, etc.)

+
+## 🚀 Quick Start

-## Getting started
 ```bash
+# Install all workspace dependencies
 pnpm install
-pnpm dev
+
+# Run both frontend and backend
+pnpm dev:full
+
+# Or run separately
+pnpm dev           # Frontend only (port 5173)
+pnpm dev:server    # Backend only (port 3001)
 ```

-## Using the shadcn CLI
-The project is already initialized with `components.json`. Add more components with:
+Visit:
+
+- **Frontend**: http://localhost:5173
+- **Backend**: http://localhost:3001
+- **Demo Page**: http://localhost:5173/trpc-demo
+
+## 📚 Workspaces
+
+### @repo/frontend (Root)
+
+The React + Vite frontend application
+
+**Location**: `/` (root directory)
+
+**Tech Stack**:
+
+- React 19 with TypeScript
+- Vite 7 for bundling
+- TailwindCSS 4 for styling
+- shadcn/ui components
+- React Router v6
+- tRPC React Query client
+
+**Scripts**:
+
 ```bash
-pnpm dlx shadcn@latest add <component>
+pnpm dev              # Start dev server
+pnpm build            # Build for production
+pnpm lint             # Run ESLint
 ```
-Examples:
+
+### @repo/server
+
+The Express + tRPC backend API
+
+**Location**: `/server`
+
+**Tech Stack**:
+
+- Express 5 web server
+- tRPC 11 for type-safe APIs
+- TaylorDB query builder
+- Zod for validation
+- TypeScript 5
+
+**Scripts**:
+
 ```bash
-pnpm dlx shadcn@latest add dialog dropdown-menu table
+pnpm --filter @repo/server dev      # Start with hot reload
+pnpm --filter @repo/server build    # Build TypeScript
+pnpm --filter @repo/server start    # Run production build
 ```
-Generated files go into `src/components/ui/` and use the shared Tailwind tokens in `src/index.css`.

-### Available components
- Layout/structure: `card`, `tabs`
- Form controls: `input`, `label`, `textarea`, `select`
- Feedback: `alert`
- Buttons: `button`
+## 🛠️ Available Scripts

-## TaylorDB integration
-Use the generated TaylorDB client and types (expected in `src/lib/taylordb.client.ts` and `src/lib/taylordb.types.ts`) to query data directly. Do not use mock data.
+### Root Commands (run from anywhere)

-## Scripts
- `pnpm dev` — run Vite dev server (HMR)
- `pnpm build` — type-check + build
- `pnpm lint` — ESLint (strict, no `any`)
+```bash
+# Development
+pnpm dev:full        # Run both workspaces concurrently
+pnpm dev             # Frontend only
+pnpm dev:server      # Backend only

-## Notes
- Tailwind 4 uses `@tailwindcss/vite`; CSS entry is `@import "tailwindcss";` in `src/index.css`.
- Tailwind config is in `tailwind.config.js`; CSS tokens live in `src/index.css`.
- Components use `@/lib/utils` for the `cn` helper (clsx + tailwind-merge).
+# Building
+pnpm build           # Build frontend
+pnpm build:server    # Build backend
+pnpm build:all       # Build both
+
+# Other
+pnpm lint            # Lint all code
+pnpm generate:schema # Generate TaylorDB types
+```
+
+### Workspace-Specific Commands
+
+```bash
+# Run command in specific workspace
+pnpm --filter @repo/frontend <command>
+pnpm --filter @repo/server <command>
+
+# Examples
+pnpm --filter @repo/server dev
+pnpm --filter @repo/frontend build
+```
+
+## 🔧 Configuration Files
+
+### pnpm-workspace.yaml
+
+Defines workspace packages:
+
+```yaml
+packages:
+  - "server"
+  - "."
+```
+
+### Package Names
+
+- Frontend: `@repo/frontend`
+- Backend: `@repo/server`
+
+All packages are marked as `private: true` (not published to npm)
+
+## 📡 API Communication
+
+### tRPC Router Export
+
+The backend exports its router type from `server/router.ts`:
+
+```typescript
+export type AppRouter = typeof appRouter;
+```
+
+### Frontend tRPC Client
+
+The frontend imports the type for end-to-end type safety:
+
+```typescript
+import type { AppRouter } from "../../server/router";
+export const trpc = createTRPCReact<AppRouter>();
+```
+
+**Note**: This works because both packages are in the same monorepo, allowing direct TypeScript imports without shared packages.
+
+## 🗄️ TaylorDB Integration
+
+### Setup
+
+1. Copy `.env.example` to `.env`
+2. Add your TaylorDB credentials:
+   ```bash
+   TAYLORDB_BASE_URL=your_base_url
+   TAYLORDB_BASE_ID=your_base_id
+   TAYLORDB_API_KEY=your_api_key
+   ```
+3. Generate types: `pnpm generate:schema`
+
+### CRUD Operations
+
+50+ type-safe procedures available:
+
+- **Weight Tracking**: Full CRUD + statistics
+- **Goals Management**: Create, read, update, delete
+- **Strength Workouts**: Exercise logging
+- **Cardio Exercises**: Duration, distance, speed tracking
+- **Calories/Nutrition**: Daily totals and aggregations
+- **Settings**: Key-value configuration
+
+See [TAYLORDB_INTEGRATION.md](file:///Users/thetaung/Desktop/taylordb-clientserver-template/TAYLORDB_INTEGRATION.md) for detailed examples.
+
+## 🏗️ Monorepo Benefits
+
+### For This Project
+
+✅ **Shared Types**: Frontend and backend share TypeScript types directly  
+✅ **Single Repository**: One git repo, one pnpm-lock.yaml  
+✅ **Coordinated Builds**: Build both projects together  
+✅ **Simplified Setup**: One `pnpm install` for everything  
+✅ **Workspace Commands**: Target specific packages easily
+
+### Compared to Separate Repos
+
+- ⚡ Faster development (no publishing to npm for type updates)
+- 🔒 Type safety guaranteed at development time
+- 📝 Simpler dependency management
+- 🔄 Atomic commits across frontend and backend
+
+## 📦 Dependency Management
+
+### Installing Dependencies
+
+**For frontend**:
+
+```bash
+# From root
+pnpm add <package>
+
+# Or explicitly
+pnpm --filter @repo/frontend add <package>
+```
+
+**For backend**:
+
+```bash
+pnpm --filter @repo/server add <package>
+```
+
+**For both**:
+
+```bash
+pnpm add <package> -w  # Add to root workspace
+```
+
+### Workspace Dependencies
+
+Workspaces can depend on each other using `workspace:*`:
+
+```json
+{
+  "dependencies": {
+    "@repo/shared": "workspace:*"
+  }
+}
+```
+
+## 🚢 Deployment
+
+### Option 1: Deploy Separately
+
+- Frontend → Vercel/Netlify (static site from `dist/`)
+- Backend → Railway/Render/Fly.io (Node.js app)
+
+Build commands:
+
+```bash
+pnpm build           # Frontend
+pnpm build:server    # Backend
+```
+
+### Option 2: Deploy Together
+
+Serve frontend from backend:
+
+```bash
+pnpm build:all       # Build both
+# Configure Express to serve frontend static files
+```
+
+### Environment Variables
+
+Set these in your deployment platform:
+
+- `TAYLORDB_BASE_URL`
+- `TAYLORDB_BASE_ID`
+- `TAYLORDB_API_KEY`
+- `FRONTEND_URL` (for CORS)
+- `VITE_TRPC_URL` (frontend)
+
+## 🎯 Next Steps
+
+1. **Add Shared Package** (optional):
+
+   ```bash
+   mkdir packages/shared
+   # Create package.json for shared utilities/types
+   ```
+
+2. **Add Tests**:
+
+   ```bash
+   pnpm --filter @repo/server add -D vitest
+   pnpm --filter @repo/frontend add -D vitest
+   ```
+
+3. **CI/CD**:
+   - Use `pnpm install --frozen-lockfile` in CI
+   - Run `pnpm build:all` for deployment
+   - Cache `node_modules` and `.pnpm-store`

+### [.env.example](file:///Users/thetaung/Desktop/taylordb-clientserver-template/.env.example)
+
+Environment configuration template with all required variables.
+
+---
+
+## Usage Examples
+
+### Frontend (React Component)
+
+```typescript
+import { trpc } from "@/lib/trpc";
+
+function WeightTracker() {
+  // Query all weights
+  const { data: weights } = trpc.weight.getAll.useQuery();
+
+  // Create mutation
+  const createWeight = trpc.weight.create.useMutation({
+    onSuccess: () => {
+      // Refetch or invalidate queries
+    },
+  });
+
+  // Add new weight entry
+  const handleSubmit = () => {
+    createWeight.mutate({
+      date: "2026-01-08",
+      weight: 75.5,
+      name: "Morning weight",
+    });
+  };
+
+  return (
+    <div>
+      {weights?.map((w) => (
+        <div key={w.id}>
+          {w.date}: {w.weight}kg
+        </div>
+      ))}
+    </div>
+  );
+}
+```
+
+### Backend (Direct Query Builder Usage)
+
+```typescript
+import * as db from "./taylordb/query-builder";
+
+// Get workouts for specific exercise
+const pushups = await db.getStrengthWorkouts("Push-ups");
+
+// Create cardio session with auto-calculated speed
+await db.createCardioExercise({
+  exercise: "Running",
+  duration: 30, // minutes
+  distance: 5, // km
+  date: "2026-01-08",
+  // speed is automatically calculated: 5km / 0.5hr = 10km/h
+});
+
+// Get nutrition totals for today
+const nutrition = await db.getTotalCaloriesForDate("2026-01-08");
+console.log(nutrition.totalCalories.sum); // e.g., 2000
+```
+
+---
+
+## Key Features
+
+### Type Safety
+
+- Full end-to-end type inference
+- TypeScript autocomplete for all operations
+- Zod runtime validation
+
+### Query Builder Features
+
+- **Filtering**: Date ranges, text search, numeric comparisons
+- **Aggregations**: Sum, average, min/max, statistics
+- **Batch Operations**: Delete multiple records
+- **Auto-calculations**: Speed calculation for cardio
+
+### Organization
+
+- Grouped by domain (weight, goals, strength, etc.)
+- Clear naming conventions
+- Comprehensive documentation
+
+---
+
+## Next Steps
+
+1. **Copy `.env.example` to `.env`** and add your TaylorDB credentials
+2. **Generate types**: Run `pnpm generate:schema` to create TaylorDB types
+3. **Test endpoints**: Use the tRPC demo page or create your own
+4. **Add authentication**: Protect procedures as needed
+5. **Customize**: Add more procedures for your specific use cases
+
+---
+
+## TypeScript Notes
+
+The type errors you see are expected until you:
+
+1. Set up TaylorDB credentials in `.env`
+2. Run `pnpm generate:schema` to generate proper types
+3. Restart the TypeScript server
+
+The code is ready to use - the types will align once TaylorDB is properly configured!
