Fix Docker deployment by resolving module resolution errors

Update build process and imports to ensure Node.js ESM compatibility for Docker deployments, addressing ERR_MODULE_NOT_FOUND errors by separating server compilation and adding .js extensions to all relative imports.

+# Docker Deployment - Ready for Production! 🚀
+
+Your TaskFlow application is now **fully fixed** and ready for Docker deployment via Drone CI.
+
+## What Was Fixed
+
+### Issue 1: Vite Module Not Found ❌
+```
+Error [ERR_MODULE_NOT_FOUND]: Cannot find package 'vite' imported from /app/dist/index.js
+```
+
+**Cause**: esbuild was bundling all server code including vite references into production.
+
+**Fix**: 
+- ✅ Created `server/static.ts` - production-only module (no vite)
+- ✅ Split server compilation into separate files
+- ✅ Conditional module loading based on NODE_ENV
+
+### Issue 2: ESM Module Resolution ❌
+```
+Error [ERR_MODULE_NOT_FOUND]: Cannot find module '/app/dist/routes' imported from /app/dist/index.js
+```
+
+**Cause**: Node.js ESM requires explicit `.js` extensions in imports.
+
+**Fix**: 
+- ✅ Added `.js` extensions to all relative imports:
+  - `server/index.ts`
+  - `server/routes.ts`
+  - `server/storage.ts`
+  - `server/db.ts`
+- ✅ Changed `@shared/schema` imports to `../shared/schema.js`
+
+## Deployment Steps
+
+### 1. Commit and Push Your Code
+
+```bash
+git add .
+git commit -m "Fix Docker ESM module resolution"
+git push
+```
+
+### 2. Drone CI Builds Your Image
+
+Drone will automatically:
+- Build your Docker image
+- Push it to `registry.local.nothaft.cloud/taskflow:latest`
+
+### 3. Deploy on Your Server
+
+```bash
+# Pull the latest image
+docker pull registry.local.nothaft.cloud/taskflow:latest
+
+# Create .env file (if you haven't already)
+cat > .env << EOF
+POSTGRES_PASSWORD=your_secure_password_here
+EOF
+
+# Start the application
+docker-compose up -d
+
+# Check logs
+docker-compose logs -f app
+```
+
+## Expected Output
+
+When the container starts successfully, you should see:
+
+```
+serving on port 5000
+Checking database schema...
+Database schema is up to date
+✓ Database initialized successfully
+```
+
+## What Works Now
+
+✅ **Development Mode** (local)
+- Vite dev server with HMR
+- Fast refresh and debugging
+- All features work
+
+✅ **Production Mode** (Docker)
+- No vite dependencies
+- Serves pre-built static files
+- PostgreSQL database
+- Automatic schema creation
+- Health checks
+
+## Architecture
+
+### Development
+```
+NODE_ENV=development → imports vite.js → Vite dev server
+```
+
+### Production (Docker)
+```
+NODE_ENV=production → imports static.js → Static file serving
+```
+
+## Files Changed
+
+- ✅ `server/static.ts` - New production module
+- ✅ `server/index.ts` - ESM imports with `.js`
+- ✅ `server/routes.ts` - ESM imports with `.js`
+- ✅ `server/storage.ts` - ESM imports with `.js`
+- ✅ `server/db.ts` - ESM imports with `.js`
+- ✅ `Dockerfile` - Separate file compilation
+- ✅ `DOCKER-FIX.md` - Technical documentation
+- ✅ `DOCKER-COMPOSE.md` - Updated with troubleshooting
+
+## No Configuration Changes Needed
+
+Your existing configuration files work perfectly:
+- ✅ `.drone.yml` - No changes needed
+- ✅ `docker-compose.yml` - No changes needed
+- ✅ `package.json` - No changes needed
+
+## Verification
+
+After deployment, test your application:
+
+```bash
+# Check health endpoint
+curl http://your-server:5000/api/health
+
+# Expected response:
+{"status":"ok","timestamp":"2025-10-23T..."}
+```
+
+## Support Documentation
+
+- **DOCKER-FIX.md** - Detailed technical explanation
+- **DOCKER-COMPOSE.md** - Complete deployment guide
+- **docker-compose.yml** - Docker compose configuration
+- **.drone.yml** - CI/CD pipeline configuration
+
+## What's Next?
+
+1. Push your code to trigger Drone CI build
+2. Wait for the image to build (~2-5 minutes)
+3. Pull and deploy on your server
+4. Access your application at `http://your-server:5000`
+
+Your TaskFlow application is production-ready! 🎉

 ## Root Cause

+The issue occurred because of two problems:
 
+### Problem 1: Bundled vite imports
 1. **Build Process**: The original build script used esbuild with the `--bundle` flag, which bundled all imports (including dynamic imports) into a single `dist/index.js` file
 2. **Production Dependencies**: The Dockerfile only installed production dependencies (excluding dev dependencies like `vite`)
 3. **Import Resolution**: Even though the code conditionally imported vite only in development, the bundled JavaScript still contained references to the vite module
 4. **Runtime Failure**: At runtime in production, Node.js tried to resolve the vite module which wasn't available in node_modules
 
+### Problem 2: Missing .js extensions in ESM imports
+After fixing the bundling issue, a second error appeared:
+```
+Error [ERR_MODULE_NOT_FOUND]: Cannot find module '/app/dist/routes' imported from /app/dist/index.js
+```
+
+This happened because:
+1. **TypeScript Convention**: TypeScript allows imports without `.js` extensions (e.g., `import { x } from './module'`)
+2. **esbuild Compilation**: When esbuild compiles without bundling, it doesn't automatically add `.js` extensions to import paths
+3. **Node.js ESM Requirement**: Node.js ESM loader strictly requires explicit file extensions (e.g., `import { x } from './module.js'`)
+4. **Runtime Failure**: Node.js couldn't resolve module paths without the `.js` extension
