### 2. **Connection Management** 🔴 CRITICAL
65
-
**Status:** ⚠️ **IMPROVED** - Connection pooling options exposed, but still missing advanced features
64
+
### 2. **Connection Management** 🟡 IMPORTANT
65
+
**Status:** ✅ **SIGNIFICANTLY IMPROVED** - Connection pooling, retry logic, and health checks implemented
- ✅ Connection pooling configuration exposed via `MongoClientOptions`
- ✅ Users can configure `maxPoolSize`, `minPoolSize`, `maxIdleTimeMS`, etc.
- ✅ All MongoDB driver connection options available
- ✅ Leverages MongoDB driver's built-in pooling (no custom implementation)
72
+
- ✅ Automatic retry logic exposed (`retryReads`, `retryWrites`)
73
+
- ✅ Health check functionality with response time monitoring
74
+
- ✅ Comprehensive timeout configurations
75
+
- ✅ Server health check intervals (`heartbeatFrequencyMS`)
74
-
- ⚠️ No connection retry logic
75
-
- ⚠️ No health checks
76
-
- ⚠️ No connection event handling
78
+
- ⚠️ No connection event handling (connected, disconnected, error events)
- ⚠️ Cannot connect to multiple databases (singleton pattern)
- ⚠️ No connection string validation
79
-
- ⚠️ No automatic reconnection on connection loss
81
+
- ⚠️ No manual reconnection API
···
- Connection options (readPreference, etc.)
89
-
- Application crashes on connection loss (no automatic recovery)
90
-
- No monitoring capabilities
91
-
- Cannot use multiple databases in same application
91
+
- ✅ Automatic retry on transient failures (reads and writes)
92
+
- ✅ Health monitoring via `healthCheck()` function
93
+
- ⚠️ Still cannot use multiple databases in same application
94
+
- ⚠️ No event-driven connection state monitoring

### 6. **Error Handling** 🟡 IMPORTANT
200
-
**Status:** Basic error handling
203
-
- Generic Error types
204
-
- No custom error classes
205
-
- Poor error messages
206
-
- No error recovery strategies
207
-
- Validation errors not structured
209
-
**Mongoose Provides:**
210
-
- `ValidationError`
213
-
- Detailed error paths
214
-
- Error recovery utilities
218
+
### 6. **Error Handling** 🟢 GOOD
219
+
**Status:** ✅ **SIGNIFICANTLY IMPROVED** - Custom error classes with structured information
221
+
**Current Features:**
222
+
- ✅ Custom error class hierarchy (all extend `NozzleError`)
223
+
- ✅ `ValidationError` with structured Zod issues
224
+
- ✅ `ConnectionError` with URI context
225
+
- ✅ `ConfigurationError` for invalid options
226
+
- ✅ `DocumentNotFoundError` for missing documents
227
+
- ✅ `OperationError` for database operation failures
228
+
- ✅ `AsyncValidationError` for unsupported async validation
229
+
- ✅ Field-specific error grouping via `getFieldErrors()`
230
+
- ✅ Operation context (insert/update/replace) in validation errors
231
+
- ✅ Proper error messages with context
232
+
- ✅ Stack trace preservation
234
+
**Remaining Gaps:**
235
+
- ⚠️ No CastError equivalent (MongoDB driver handles this)
236
+
- ⚠️ No custom MongoError wrapper (uses native MongoDB errors)
237
+
- ⚠️ No error recovery utilities/strategies
239
+
**Mongoose Comparison:**
240
+
- ✅ ValidationError - Similar to Mongoose
241
+
- ✅ Structured error details - Better than Mongoose (uses Zod issues)
242
+
- ❌ CastError - Not implemented (less relevant with Zod)
243
+
- ⚠️ MongoError - Uses native driver errors

## 🔍 Code Quality Issues
314
-
### 1. **Error Messages**
316
-
// Current: Generic error
317
-
throw new Error(`Validation failed: ${JSON.stringify(result.issues)}`);
319
-
// Should be: Structured error with details
320
-
throw new ValidationError(result.issues, schema);

### 2. **Type Safety Gaps**
343
+
## 🔍 Code Quality Issues
345
+
### 1. **Error Messages**
346
+
✅ **RESOLVED** - Now uses custom error classes:
348
+
// Current implementation
349
+
throw new ValidationError(result.error.issues, "insert");
351
+
// Provides structured error with:
352
+
// - Operation context (insert/update/replace)
353
+
// - Zod issues array
354
+
// - Field-specific error grouping via getFieldErrors()
357
+
### 2. **Type Safety Gaps**
validatedData as OptionalUnlessRequiredId<Infer<T>>
···
- Direct MongoDB query passthrough
334
-
### 4. **Connection State Management**
336
-
// No way to check if connected
337
-
// No way to reconnect
338
-
// No connection state events
368
+
### 4. **Connection State Management**
369
+
✅ **PARTIALLY RESOLVED**
371
+
// Now have health check
372
+
const health = await healthCheck();
373
+
if (!health.healthy) {
374
+
// Handle unhealthy connection
378
+
// - Connection state events
379
+
// - Manual reconnection API
