Walkthrough

The pull request introduces changes to the server initialization process across multiple files. In src/app.ts, two import statements and their corresponding function calls related to database connection and log file creation listener have been removed. The src/index.ts file has been significantly refactored to wrap server initialization within an asynchronous function, establishing a database connection before starting HTTP and HTTPS servers. The src/services/mongoService.ts file has been updated to explicitly export the connectDatabase function with a more precise type signature. These modifications aim to improve the server startup sequence and logging mechanisms.

Assessment against linked issues

Objective	Addressed	Explanation
Print localhost link on terminal after server run [#622]	✅

The changes fully address the requirement from issue #622 by adding a log message in src/index.ts that prints the WebUI access URL to the console during server initialization. The implementation matches the specified description of printing the localhost link after the server runs.

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

Review comments: Directly reply to a review comment made by CodeRabbit. Example:
- I pushed a fix in commit <commit_id>, please review it.
- Generate unit testing code for this file.
- Open a follow-up GitHub issue for this discussion.
Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
- @coderabbitai generate unit testing code for this file.
- @coderabbitai modularize this function.
PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
- @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
- @coderabbitai read src/utils.ts and generate unit testing code.
- @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
- @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

16-16: Exit gracefully if database connection fails.
Although errors are logged inside “connectDatabase”, consider exiting the process or implementing fallback logic if the connection fails, to avoid running the server in a partial state.

20-23: Secure your certificates.
Loading certificates from “static/certs” is fine for development, but in production, consider a more secure approach for managing TLS keys (e.g., environment variables or vault).

25-34: Avoid nesting server creations and reduce callback depth.
Starting the HTTPS server within the HTTP server’s callback can be simplified by initializing them in parallel. Nonetheless, the improved log message that directs the user to “http://localhost” is a great usability enhancement.

src/services/mongoService.ts (1)

Line range hint 11-19: Consider returning the Mongoose connection object.
Currently, the function only returns void. If other parts of the code need access to the Mongoose connection, returning the connection (or storing it in a shared variable) can prevent re-connection overhead. Otherwise, this is a well-defined approach with proper logging.

10-11: All good with the new imports.
The direct imports from "mongoService" and "logger" are clearly defined and help clarify the new initialization flow.

15-15: Neat usage of an async IIFE.
This pattern is a clean way to handle top-level async code while keeping the global scope minimal.

18-19: Validate port configurations.
Ensure “httpPort” and “httpsPort” come from valid environment variables or config values; otherwise consider logging a warning when defaulting to 80 or 443.

💡 Codebase verification

Based on the code analysis, I can now provide a final response:

Log file creation handling needs improvement
The current implementation of registerLogFileCreationListener only logs successful file creation/rotation events but lacks error handling. Consider adding error event listeners to handle potential file system issues:

Add error event handlers for both errorLog and combinedLog transports
Handle scenarios like permission issues or disk space problems
Consider implementing a fallback mechanism when file logging fails

Example:

errorLog.on('error', error => logger.error('Error with error log file:', error));
combinedLog.on('error', error => logger.error('Error with combined log file:', error));

🔗 Analysis chain

Consider verifying log file creation.
The function call “registerLogFileCreationListener()” looks fine. As a good practice, ensure any potential errors or edge cases (e.g., restricted file permissions) are handled or at least logged appropriately.

Let me search for the implementation of registerLogFileCreationListener to verify how it handles errors and edge cases.

Let me check how errorLog and combinedLog are initialized and if they handle file system errors properly.

Let me search for error handling around the log file creation.

Let me check how the logger is configured and if there's any error handling at the transport level.
