+# Production-Readiness Plan for smarts3
+
+**Goal:** Make smarts3 production-ready as a MinIO alternative for use cases where:
+- Running MinIO is out of scope
+- You have a program written for S3 and want to use the local filesystem
+- You need a lightweight, zero-dependency S3-compatible server
+
+---
+
+## 🔍 Current State Analysis
+
+### ✅ What's Working
+
+- **Native S3 server** with zero framework dependencies
+- **Core S3 operations:** PUT, GET, HEAD, DELETE (objects & buckets)
+- **List buckets and objects** (V1 and V2 API)
+- **Object copy** with metadata handling
+- **Range requests** for partial downloads
+- **MD5 checksums** and ETag support
+- **Custom metadata** (x-amz-meta-*)
+- **Filesystem-backed storage** with Windows compatibility
+- **S3-compatible XML error responses**
+- **Middleware system** and routing
+- **AWS SDK v3 compatibility** (tested)
+
+### ❌ Production Gaps Identified
+
+---
+
+## 🎯 Critical Features (Required for Production)
+
+### 1. Multipart Upload Support 🚀 **HIGHEST PRIORITY**
+
+**Why:** Essential for uploading files >5MB efficiently. Without this, smarts3 can't handle real-world production workloads.
+
+**Implementation Required:**
+- `POST /:bucket/:key?uploads` - CreateMultipartUpload
+- `PUT /:bucket/:key?partNumber=X&uploadId=Y` - UploadPart
+- `POST /:bucket/:key?uploadId=X` - CompleteMultipartUpload
+- `DELETE /:bucket/:key?uploadId=X` - AbortMultipartUpload
+- `GET /:bucket/:key?uploadId=X` - ListParts
+- Multipart state management (temp storage for parts)
+- Part ETag tracking and validation
+- Automatic cleanup of abandoned uploads
+
+**Files to Create/Modify:**
+- `ts/controllers/multipart.controller.ts` (new)
+- `ts/classes/filesystem-store.ts` (add multipart methods)
+- `ts/classes/smarts3-server.ts` (add multipart routes)
+
+---
+
+### 2. Configurable Authentication 🔐
+
+**Why:** Currently hardcoded credentials ('S3RVER'/'S3RVER'). Production needs custom credentials.
+
+**Implementation Required:**
+- Support custom access keys and secrets via configuration
+- Implement AWS Signature V4 verification
+- Support multiple credential pairs (IAM-like users)
+- Optional: Disable authentication for local dev use
+
+**Configuration Example:**
+```typescript
+interface IAuthConfig {
+  enabled: boolean;
+  credentials: Array<{
+    accessKeyId: string;
+    secretAccessKey: string;
+  }>;
+  signatureVersion: 'v4' | 'none';
+}
+```
+
+**Files to Create/Modify:**
+- `ts/classes/auth-middleware.ts` (new)
+- `ts/classes/signature-validator.ts` (new)
+- `ts/classes/smarts3-server.ts` (integrate auth middleware)
+- `ts/index.ts` (add auth config options)
+
+---
+
+### 3. CORS Support 🌐
+
+**Why:** Required for browser-based uploads and modern web apps.
+
+**Implementation Required:**
+- Add CORS middleware
+- Support preflight OPTIONS requests
+- Configurable CORS origins, methods, headers
+- Per-bucket CORS configuration (optional)
+
+**Configuration Example:**
+```typescript
+interface ICorsConfig {
+  enabled: boolean;
+  allowedOrigins: string[]; // ['*'] or ['https://example.com']
+  allowedMethods: string[]; // ['GET', 'POST', 'PUT', 'DELETE']
+  allowedHeaders: string[]; // ['*'] or specific headers
+  exposedHeaders: string[]; // ['ETag', 'x-amz-*']
+  maxAge: number; // 3600 (seconds)
+  allowCredentials: boolean;
+}
+```
+
+**Files to Create/Modify:**
+- `ts/classes/cors-middleware.ts` (new)
+- `ts/classes/smarts3-server.ts` (integrate CORS middleware)
+- `ts/index.ts` (add CORS config options)
+
+---
+
+### 4. SSL/TLS Support 🔒
+
+**Why:** Production systems require encrypted connections.
+
+**Implementation Required:**
+- HTTPS server option with cert/key configuration
+- Auto-redirect HTTP to HTTPS (optional)
+- Support for self-signed certs in dev mode
+
+**Configuration Example:**
+```typescript
+interface ISslConfig {
+  enabled: boolean;
+  cert: string; // Path to certificate file or cert content
+  key: string; // Path to key file or key content
+  ca?: string; // Optional CA cert
+  redirectHttp?: boolean; // Redirect HTTP to HTTPS
+}
+```
+
+**Files to Create/Modify:**
+- `ts/classes/smarts3-server.ts` (add HTTPS server creation)
+- `ts/index.ts` (add SSL config options)
+
+---
+
+### 5. Production Configuration System ⚙️
+
+**Why:** Production needs flexible configuration, not just constructor options.
+
+**Implementation Required:**
+- Support configuration file (JSON/YAML)
+- Environment variable support
+- Configuration validation
+- Sensible production defaults
+- Example configurations for common use cases
+
+**Configuration File Example (`smarts3.config.json`):**
+```json
+{
+  "server": {
+    "port": 3000,
+    "address": "0.0.0.0",
+    "ssl": {
+      "enabled": true,
+      "cert": "./certs/server.crt",
+      "key": "./certs/server.key"
+    }
+  },
+  "storage": {
+    "directory": "./s3-data",
+    "cleanSlate": false
+  },
+  "auth": {
+    "enabled": true,
+    "credentials": [
+      {
+        "accessKeyId": "AKIAIOSFODNN7EXAMPLE",
+        "secretAccessKey": "wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY"
+      }
+    ]
+  },
+  "cors": {
+    "enabled": true,
+    "allowedOrigins": ["*"],
+    "allowedMethods": ["GET", "POST", "PUT", "DELETE", "HEAD"],
+    "allowedHeaders": ["*"]
+  },
+  "limits": {
+    "maxObjectSize": 5368709120,
+    "maxMetadataSize": 2048,
+    "requestTimeout": 300000
+  },
+  "logging": {
+    "level": "info",
+    "format": "json",
+    "accessLog": {
+      "enabled": true,
+      "path": "./logs/access.log"
+    },
+    "errorLog": {
+      "enabled": true,
+      "path": "./logs/error.log"
+    }
+  }
+}
+```
+
+**Files to Create/Modify:**
+- `ts/classes/config-loader.ts` (new)
+- `ts/classes/config-validator.ts` (new)
+- `ts/index.ts` (use config loader)
+- Create example config files in root
+
+---
+
+### 6. Production Logging 📝
+
+**Why:** Console logs aren't suitable for production monitoring.
+
+**Implementation Required:**
+- Structured logging (JSON format option)
+- Log levels (ERROR, WARN, INFO, DEBUG)
+- File rotation support
+- Access logs (S3 standard format)
+- Integration with logging library
+
+**Files to Create/Modify:**
+- `ts/classes/logger.ts` (new - use @push.rocks/smartlog?)
+- `ts/classes/access-logger-middleware.ts` (new)
+- `ts/classes/smarts3-server.ts` (replace console.log with logger)
+- All controller files (use structured logging)
+
+---
+
+## 🔧 Important Features (Should Have)
+
+### 7. Health Check & Metrics 💊
+
+**Implementation Required:**
+- `GET /_health` endpoint (non-S3, for monitoring)
+- `GET /_metrics` endpoint (Prometheus format?)
+- Server stats (requests/sec, storage used, uptime)
+- Readiness/liveness probes for Kubernetes
+
+**Files to Create/Modify:**
+- `ts/controllers/health.controller.ts` (new)
+- `ts/classes/metrics-collector.ts` (new)
+- `ts/classes/smarts3-server.ts` (add health routes)
+
+---
+
+### 8. Batch Operations 📦
+
+**Implementation Required:**
+- `POST /:bucket?delete` - DeleteObjects (delete multiple objects in one request)
+- Essential for efficient cleanup operations
+
+**Files to Create/Modify:**
+- `ts/controllers/object.controller.ts` (add deleteObjects method)
+
+---
+
+### 9. Request Size Limits & Validation 🛡️
+
+**Implementation Required:**
+- Max object size configuration
+- Max metadata size limits
+- Request timeout configuration
+- Body size limits
+- Bucket name validation (S3 rules)
+- Key name validation
+
+**Files to Create/Modify:**
+- `ts/classes/validation-middleware.ts` (new)
+- `ts/utils/validators.ts` (new)
+- `ts/classes/smarts3-server.ts` (integrate validation middleware)
+
+---
+
+### 10. Conditional Requests 🔄
+
+**Implementation Required:**
+- If-Match / If-None-Match (ETag validation)
+- If-Modified-Since / If-Unmodified-Since
+- Required for caching and conflict prevention
+
+**Files to Create/Modify:**
+- `ts/controllers/object.controller.ts` (add conditional logic to GET/HEAD)
+
+---
+
+### 11. Graceful Shutdown 👋
+
+**Implementation Required:**
+- Drain existing connections
+- Reject new connections
+- Clean multipart cleanup on shutdown
+- SIGTERM/SIGINT handling
+
+**Files to Create/Modify:**
+- `ts/classes/smarts3-server.ts` (add graceful shutdown logic)

+17. ✅ Advanced features based on user feedback
+
+**Outcome:** smarts3 is a complete MinIO alternative
+
+---
+
+## 🤔 Open Questions
+
+1. **Authentication:** Do you want full AWS Signature V4 validation, or simpler static credential checking?
+2. **Configuration:** Prefer JSON, YAML, or .env file format?
+3. **Logging:** Do you have a preferred logging library, or shall I use @push.rocks/smartlog?
+4. **Scope:** Should we tackle all of Phase 1, or start with a subset (e.g., just multipart + auth)?
+5. **Testing:** Should we add comprehensive tests as we go, or batch them at the end?
+6. **Breaking changes:** Can I modify the constructor options interface, or must it remain backward compatible?
+
+---
+
+## 🎯 Target Use Cases
+
+**With this plan implemented, smarts3 will be a solid MinIO alternative for:**
+
+✅ **Local S3 development** - Fast, simple, no Docker required
+✅ **Testing S3 integrations** - Reliable, repeatable tests

+- `ts/classes/s3-error.ts` - S3-compatible error handling
+- `ts/controllers/` - Service, bucket, and object controllers
+- `ts/index.ts` - Main export (Smarts3 class)
+
+### Storage Layout
+- Objects stored as: `{bucket}/{encodedKey}._S3_object`
+- Metadata stored as: `{bucket}/{encodedKey}._S3_object.metadata.json`
+- MD5 stored as: `{bucket}/{encodedKey}._S3_object.md5`
+- Keys are encoded for Windows compatibility (hex encoding for invalid chars)
+
+### Current Limitations
+- Max file size limited by available memory (no streaming multipart)
+- Single server instance only (no clustering)
+- No versioning support
+- No access control beyond basic auth
+
+## Testing
+
+- Main test: `test/test.aws-sdk.node.ts` - Tests AWS SDK v3 compatibility
+- Run with: `pnpm test`
+- Tests run with cleanSlate mode enabled
+
+## Dependencies
+
+- `@push.rocks/smartbucket` - S3 abstraction layer
+- `@push.rocks/smartfs` - Modern filesystem operations with Web Streams API (replaced smartfile)
+- `@push.rocks/smartxml` - XML generation/parsing
+- `@push.rocks/smartpath` - Path utilities
+- `@tsclass/tsclass` - TypeScript utilities
+
+## Migration Notes (2025-11-23)
+
+Successfully migrated from `@push.rocks/smartfile` + native `fs` to `@push.rocks/smartfs`:
+- All file/directory operations now use smartfs fluent API
+- Web Streams → Node.js Streams conversion for HTTP compatibility
+- All tests passing ✅
+- Build successful ✅
+
+## Next Steps
+
+Waiting for approval to proceed with production-readiness implementation.
+Priority 1 is implementing multipart uploads.
