Walkthrough

The pull request introduces a comprehensive refactoring of error handling and logging across multiple files in the application. The primary changes involve removing explicit logging of errors and replacing them with direct error throwing. A new centralized error handling middleware (errorHandler) has been added to src/middleware/errorHandler.ts, which provides a standardized approach to processing and responding to different types of errors.

The modifications span several services, controllers, and the main application configuration, focusing on simplifying error management. The changes include removing logger imports, deleting error logging statements, and ensuring that errors are thrown with descriptive messages. The new errorHandler middleware is designed to handle various error scenarios, providing consistent error responses and logging mechanisms for the application.

These changes represent a shift towards a more streamlined error handling approach, centralizing error processing and reducing scattered logging throughout the codebase.

🪧 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.

🧹 Nitpick comments (6)

src/services/loadoutService.ts (1)

7-7: Consider using specialized error classes or attaching a status code.
Throwing a generic Error is acceptable, but using a specialized error (e.g., NotFoundError) or attaching more context (e.g., error.status = 404) may improve handling and traceability in the errorHandler middleware.

src/services/personalRoomsService.ts (1)

7-7: Use a dedicated error class for better error identification.
Similar to getLoadout, consider using a custom error type indicating a "not found" condition or augmenting the error with a status code for clearer distinction in the errorHandler.
src/middleware/errorHandler.ts (3)
5-5: Use strict comparison for string matching.
Replace == with === to avoid unexpected type coercions.
-if (err.message == "Invalid accountId-nonce pair") {
+if (err.message === "Invalid accountId-nonce pair") {
7-11: Handle potential empty or missing stack.
When err.stack is undefined or empty, splitting might fail. Consider adding a guard clause or fallback in case err.stack is not a valid string.

4-16: General improvement for production environments.
Returning an error message or stack trace directly could accidentally leak internal details. If this is a production environment, consider obfuscating or removing sensitive information from the response.
src/controllers/api/getShipController.ts (1)

46-46: Use a more descriptive or specialized error type.

Throwing a raw Error aligns with the new approach of removing logging statements in favor of throwing errors. However, consider using a specialized error type or including additional status information so the errorHandler middleware can respond with more context (e.g., HTTP 404).

src/app.ts (2)

5-5: Good practice: Keep error handling middleware logically last.
Ensure that the errorHandler is used after all routes (including unknownEndpointHandler) so that any unhandled endpoint or error is caught at the end.

24-24: Validate appropriate order of middleware usage.
Double-check that the requestLogger middleware properly logs before errorHandler intercepts. Consider placing errorHandler as the very last middleware in the stack, following the unknownEndpointHandler.

src/controllers/api/inventoryController.ts (1)

21-21: Consider verifying error propagation from getAccountForRequest.

Removing the try-catch and allowing errors to bubble up to the new centralized errorHandler follows the PR's approach. Ensure that this function throws a clear and descriptive error (e.g., authentication expired or invalid user request) so it can be gracefully handled and presented to the client through the middleware.
