68-76: Mom's spaghetti moment: Let's decouple these services!Adding services directly to the request object creates tight coupling. Consider using a dependency injection container to manage these services more effectively.
Consider using a DI container like
awilix:import { createContainer, asClass, asValue } from 'awilix'; const container = createContainer(); container.register({ db: asValue(db), jobQueue: asValue(jobQueue), emailService: asValue(emailService), settingsService: asValue(settingsService) }); app.use((req, res, next) => { req.container = container; next(); });
158-161: There's vomit on his sweater: Let's clean up this error handling!The error logging could be more informative by including additional context and stack traces.
Enhance the error logging:
logger.error(error.message, { service: SERVICE_NAME, + stack: error.stack, + timestamp: new Date().toISOString(), + startupPhase: 'initialization' });

142-142:⚠️ Potential issueArms are heavy: Let's make the cleanup more steady!
The cleanup process needs improvement:
- Replace console.log with logger
- Add timeout for graceful shutdown
Here's how to enhance it:
-console.log("Already cleaning up"); +logger.info("Cleanup already in progress", { service: SERVICE_NAME }); -console.log("Shutting down gracefully"); +logger.info("Initiating graceful shutdown", { service: SERVICE_NAME }); +const SHUTDOWN_TIMEOUT = 10000; // 10 seconds +const shutdownTimer = setTimeout(() => { + logger.error("Forced shutdown due to timeout", { service: SERVICE_NAME }); + process.exit(1); +}, SHUTDOWN_TIMEOUT); await jobQueue.obliterate(); await db.disconnect(); +clearTimeout(shutdownTimer); -console.log("Finished cleanup"); +logger.info("Cleanup completed successfully", { service: SERVICE_NAME });Likely invalid or redundant comment.

4-5: Yo, these logging improvements are straight fire! 🔥The addition of structured logging and the SERVICE_NAME constant brings better observability to the MongoDB operations. This is a solid improvement over console.log statements.
169-169: Clean export addition, no cap! 💯The disconnect method is properly exported, maintaining consistency with the existing export structure.

Yo dawg, let's make that PORT configurable!
Instead of hardcoding the port number, we should make it configurable through environment variables. This makes the app more flexible across different environments.
Here's a better way to handle it:

Knees weak: Server startup sequence needs strengthening!
Two issues here:
- Using
console.loginstead of theloggerutility - Server starts before all services are initialized (emailService, networkService, etc.)
Fix the logging and sequence:
await db.connect();
-app.listen(PORT, () => {
- console.log(`server started on port:${PORT}`);
-});
const settingsService = new SettingsService(AppSettings);
await settingsService.loadSettings();
// ... other service initialization ...
+app.listen(PORT, () => {
+ logger.info(`Server started on port:${PORT}`, { service: SERVICE_NAME });

🛠️ Refactor suggestion
Yo dawg, we need to beef up this error handling! 💪
While the structured logging is dope, we could make this even better:
- Add connection string validation
- Include more error context in the logs
Here's how we can level up this code:
const connect = async () => {
try {
const connectionString =
process.env.DB_CONNECTION_STRING || "mongodb://localhost:27017/uptime_db";
+ if (!connectionString.startsWith('mongodb://') && !connectionString.startsWith('mongodb+srv://')) {
+ throw new Error('Invalid MongoDB connection string');
+ }
await mongoose.connect(connectionString);
// If there are no AppSettings, create one
let appSettings = await AppSettings.find();
if (appSettings.length === 0) {
appSettings = new AppSettings({});
await appSettings.save();
}
logger.info("Connected to MongoDB", { service: SERVICE_NAME, method: "connect" });
} catch (error) {
logger.error("failed to connect to MongoDB", {
service: SERVICE_NAME,
method: "connect",
+ error: error.message,
+ stack: error.stack
});
throw error;
}
};Also applies to: 24-27

🛠️ Refactor suggestion
Mom's spaghetti moment: Let's make this disconnect method bulletproof! 🍝
The disconnect method is looking clean, but we could make it even more robust with a few tweaks:
- Return success/failure status
- Add timeout handling
Here's the improved version:
const disconnect = async () => {
try {
logger.info("Disconnecting from MongoDB", { service: SERVICE_NAME });
- await mongoose.disconnect();
+ await Promise.race([
+ mongoose.disconnect(),
+ new Promise((_, reject) =>
+ setTimeout(() => reject(new Error('Disconnect timeout')), 5000)
+ )
+ ]);
logger.info("Disconnected from MongoDB", { service: SERVICE_NAME });
- return;
+ return true;
} catch (error) {
logger.error("failed to disconnect from MongoDB", {
service: SERVICE_NAME,
errorMsg: error.message,
+ stack: error.stack
});
+ return false;
}
