Always Close the Store + +```go +store, err := database.NewKV(cfg) +if err != nil { + return err +} +defer store.Close() // Always close to release resources +``` + +### 2. Use Context for Timeouts + +```go +ctx, cancel := context.WithTimeout(context.Background(), 5*time.Second) +defer cancel() + +value, err := store.Get(ctx, namespace, collection, key) +``` + +### 3. Handle Errors Properly + +```go +value, err := store.Get(ctx, namespace, collection, key) +if err != nil { + if errors.Is(err, kv.ErrKeyNotFound) { + // Handle not found case + return nil, nil + } + return nil, err +} +``` + +### 4. Validate JSON Before Storing + +```go +// Validate JSON before storing +if !json.Valid(valueBytes) { + return fmt.Errorf("invalid JSON") +} +store.Set(ctx, namespace, collection, key, valueBytes) +``` + +### 5. Use Meaningful Namespaces and Collections + +```go +// Good: Clear organization +store.Set(ctx, "production", "users", "user_123", data) +store.Set(ctx, "production", "devices", "device_456", data) + +// Bad: Unclear organization +store.Set(ctx, "data", "stuff", "item1", data) +``` + +### 6. Ping Before Critical Operations + +```go +if err := store.Ping(ctx); err != nil { + log.Fatalf("KV store is not available: %v", err) +} +// Proceed with operations +``` + +## Examples + +### Complete Example + +```go +package main + +import ( + "context" + "encoding/json" + "fmt" + "log" + "time" + + "commander/internal/config" + "commander/internal/database" + "commander/internal/kv" +) + +func main() { + // Load configuration + cfg := config.LoadConfig() + + // Create KV store + store, err := database.NewKV(cfg) + if err != nil { + log.Fatalf("Failed to create KV store: %v", err) + } + defer store.Close() + + ctx, cancel := context.WithTimeout(context.Background(), 10*time.Second) + defer cancel() + + // Verify connection + if err := store.Ping(ctx); err != nil { + log.Fatalf("Failed to ping KV store: %v", err) + } + + // Define namespace and collection + namespace := "commander" + collection := "cards" + key := "card_001" + + // Create and store data + card := map[string]interface{}{ + "name": "Fire Dragon", + "card_number": "ABC123DEF456", + "devices": []string{"device-001", "device-002"}, + "status": "active", + "created_at": time.Now().UTC().Format(time.RFC3339), + } + + valueBytes, err := json.Marshal(card) + if err != nil { + log.Fatalf("Failed to marshal: %v", err) + } + + // Store + if err := store.Set(ctx, namespace, collection, key, valueBytes); err != nil { + log.Fatalf("Failed to set: %v", err) + } + fmt.Printf("Stored: %s\n", key) + + // Check existence + exists, err := store.Exists(ctx, namespace, collection, key) + if err != nil { + log.Fatalf("Failed to check existence: %v", err) + } + fmt.Printf("Exists: %v\n", exists) + + // Retrieve + retrievedBytes, err := store.Get(ctx, namespace, collection, key) + if err != nil { + log.Fatalf("Failed to get: %v", err) + } + + var retrievedCard map[string]interface{} + if err := json.Unmarshal(retrievedBytes, &retrievedCard); err != nil { + log.Fatalf("Failed to unmarshal: %v", err) + } + + fmt.Printf("Retrieved: %+v\n", retrievedCard) + + // Delete + if err := store.Delete(ctx, namespace, collection, key); err != nil { + log.Fatalf("Failed to delete: %v", err) + } + fmt.Printf("Deleted: %s\n", key) +} +``` + +### Batch Operations Example + +```go +func batchStore(ctx context.Context, store kv.KV, namespace, collection string, items map[string]interface{}) error { + for key, value := range items { + valueBytes, err := json.Marshal(value) + if err != nil { + return fmt.Errorf("failed to marshal %s: %w", key, err) + } + + if err := store.Set(ctx, namespace, collection, key, valueBytes); err != nil { + return fmt.Errorf("failed to set %s: %w", key, err) + } + } + return nil +} +``` + +### Conditional Update Example + +```go +func conditionalUpdate(ctx context.Context, store kv.KV, namespace, collection, key string, newValue interface{}) error { + // Check if key exists + exists, err := store.Exists(ctx, namespace, collection, key) + if err != nil { + return err + } + + if !exists { + return fmt.Errorf("key %s does not exist", key) + } + + // Update + valueBytes, err := json.Marshal(newValue) + if err != nil { + return err + } + + return store.Set(ctx, namespace, collection, key, valueBytes) +} +``` + +## Migration Between Backends + +The KV abstraction layer makes it easy to switch between backends: + +```bash +# Switch from BBolt to MongoDB +export DATABASE=mongodb +export MONGODB_URI="mongodb+srv://..." + +# Switch from MongoDB to Redis +export DATABASE=redis +export REDIS_URI="redis://..." + +# Switch back to BBolt +export DATABASE=bbolt +# or just unset DATABASE (defaults to bbolt) +``` + +No code changes are required - the same interface works with all backends! + +## Troubleshooting + +### Connection Issues + +```go +// Always check connection before use +if err := store.Ping(ctx); err != nil { + log.Fatalf("Connection failed: %v", err) +} +``` + +### Invalid JSON + +```go +// Validate JSON before storing +if !json.Valid(valueBytes) { + return fmt.Errorf("invalid JSON") +} +``` + +### Namespace Not Found + +Remember that empty namespace defaults to "default": +```go +// These are equivalent: +store.Set(ctx, "", "collection", "key", value) +store.Set(ctx, "default", "collection", "key", value) +``` + +## See Also + +- [Configuration Guide](../README.md#configuration) +- [Docker

From 67a3b53b8d163588c64e64f7ecd18504441add5f Mon Sep 17 00:00:00 2001 From: Iktahana <171251543+Iktahana@users.noreply.github.com> Date: Tue, 3 Feb 2026 13:16:02 +0900 Subject: [PATCH 20/52] feat: implement KV CRUD API endpoints for /api/v1 - Implement GET /api/v1/kv/{namespace}/{collection}/{key} to retrieve values - Implement POST /api/v1/kv/{namespace}/{collection}/{key} to set values - Implement DELETE /api/v1/kv/{namespace}/{collection}/{key} to remove keys - Implement HEAD /api/v1/kv/{namespace}/{collection}/{key} to check key existence - Add request/response structures with proper error handling - Add comprehensive unit tests for all CRUD operations - Validate input parameters and normalize namespace - Return standardized JSON responses with timestamps - Achieve 81.8%

From 8b1bc475dfa14cb9e3d8e5bf5dc3f60f9cfca2b9 Mon Sep 17 00:00:00 2001 From: Iktahana <171251543+Iktahana@users.noreply.github.com> Date: Tue, 3 Feb 2026 14:44:48 +0900 Subject: [PATCH 34/52] refactor: redesign card verification API to use POST with headers and body MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit BREAKING CHANGE: Card verification endpoints redesigned New Standard API: - POST /api/v1/namespaces/:namespace - Header: X-Device-SN (device serial number) - Body: plain text card number - Response: 204 No Content (success) / Status only (error, no body) Legacy vguang-m350 API (maintained for compatibility): - POST /api/v1/namespaces/:namespace/device/:device_name - Body: plain text or binary card number - Response: 200 'code=0000' (success) / 404 (error, no body) - Special handling: alphanumeric → uppercase, binary → reversed hex Removed endpoints: - GET /api/v1/namespaces/:namespace/device/:device_sn/card/:card_number - GET /api/v1/namespaces/:namespace/device/:device_sn/card/:card_number/vguang-350 Changes: - Rewrite card.go handlers for POST endpoints - Update route registration in main.go - Rewrite card_test.go with new POST test cases - Update API documentation with new endpoint specs - Add parseVguangCardNumber() for binary card handling - Error responses now status code only (logged to console) -

-## Best Practices - -### DO -- ✅ Validate all user input -- ✅ Use environment variables for secrets -- ✅ Return generic error messages -- ✅ Log detailed errors server-side -- ✅ Use HTTPS in production -- ✅ Implement rate limiting -- ✅ Set timeouts on operations -- ✅ Use secure file permissions -- ✅ Update dependencies regularly -- ✅ Sanitize logs - -### DON'T -- ❌ Trust user input -- ❌ Hardcode secrets -- ❌ Expose internal errors -- ❌ Log passwords or tokens -- ❌ Skip input validation -- ❌ Use HTTP in production -- ❌ Ignore rate limiting -- ❌ Leave debug logs in production -- ❌ Use weak TLS versions -- ❌ Commit secrets to git - -## Security Checklist - -Before deploying: -- [ ] All secrets in environment variables -- [ ] No secrets in git history -- [ ] Input validation on all endpoints -- [ ] Rate limiting enabled -- [ ] HTTPS/TLS configured -- [ ] Error messages sanitized -- [ ] Logs don't contain secrets -- [ ] Dependencies updated -- [ ] File permissions secure (0600) -- [ ] Timeouts on all operations -
