26-36: Consider adding log rotation and configurable pathsThe logger configuration looks good overall, but there are some important considerations:
- Add log rotation to prevent logs from growing indefinitely:
const { createLogger, format, transports } = require('winston'); require('winston-daily-rotate-file'); // Add this transport instead of current File transport new transports.DailyRotateFile({ filename: 'logs/error-%DATE%.log', datePattern: 'YYYY-MM-DD', level: 'error', maxSize: '20m', maxFiles: '14d' })
- Consider making log paths configurable through environment variables or configuration file
- Add directory creation/verification before initializing file transports
Would you like me to provide a complete implementation addressing these points?

Consider either:
- Just logging without throwing:
- // console.error(err) logger.error('Error processing tool', { message: err.message, stack: err.stack, tool_name: tool?.name, url: tool?.url - }); - throw err; + });
- Or just throwing without logging here, and handling all logging in a top-level error handler:
- // console.error(err) - logger.error('Error processing tool', { - message: err.message, - stack: err.stack, - tool_name: tool?.name, - url: tool?.url - }); throw err;🧰 Tools

1-2: Verify package.json dependencies
The imports look correct. Let's verify the dependencies are properly configured in package.json.
✅ Verification successful
Dependencies are properly configured
Both winston (v3.17.0) and winston-timestamp-colorize (v1.1.0) are correctly listed in the package.json dependencies section. The imports in logger.js are properly supported by the project configuration.
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Check if winston dependencies are properly configured in package.json
# Expected: Both winston and winston-timestamp-colorize should be listed in dependencies
jq '.dependencies | has("winston") and has("winston-timestamp-colorize")' package.json

11-11: Verify logger configuration.
Let's ensure the logger is properly configured with appropriate log levels and transports as mentioned in the PR objectives.
✅ Verification successful
Logger configuration is properly set up with comprehensive logging capabilities
The logger implementation is well-configured with:
- Appropriate log levels (default: 'info')
- Console transport with colorized output and timestamps
- File transports for both error-specific ('logs/error.log') and combined logs ('logs/combined.log')
- Required dependencies (winston@3.17.0 and winston-timestamp-colorize@1.1.0) are properly specified
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Check logger configuration

118-119: Dependencies organization looks good.
The addition of Winston and its colorize plugin aligns well with the PR objectives to implement custom logging with enhanced formatting. The dependencies are properly organized based on their usage.

156-156: Verify the impact of moving fast-xml-parser to devDependencies.
The fast-xml-parser package has been moved from dependencies to devDependencies. This change implies it's only needed during development.
✅ Verification successful
Moving fast-xml-parser to devDependencies appears safe
The package is only referenced in package.json and package-lock.json files, with no usage found in the actual source code. This confirms it's safe to keep it in devDependencies since it's not being used in production code.

The following scripts were executed for the analysis:

118-119: Consider updating to the latest stable Winston version.
The PR introduces Winston for logging, but version 3.17.0 is ahead of the latest stable release (3.11.0). This could lead to stability issues.

🛠️ Refactor suggestion
Well-structured logging format with room for improvement
The custom format provides comprehensive logging with timestamps, colors, and structured output. However, there are a few improvements needed:
- Follow JavaScript naming conventions by using camelCase:
-format.printf(({ level, timestamp, message, stack, tool_name, url }) => {
+format.printf(({ level, timestamp, message, stack, toolName, url }) => {
let logMessage = `${level} at ${timestamp}`;
logMessage += `\n${message}`;
- if (tool_name) {
- logMessage += `\n Tool: ${tool_name}`;
+ if (toolName) {
+ logMessage += `\n Tool: ${toolName}`;
}- Remove unnecessary empty line at line 9

Fix validation error logging implementation.
There are several issues in this block:
- The
errvariable is undefined as this is the validation block - The validation errors from
validate.errorsare not being logged - The comment on line 105 is unnecessary
Apply this fix:
- // console.error('Script is not failing, it is just dropping errors for further investigation');
- // console.error('Invalid .asyncapi-tool file.');
- // console.error(`Located in: ${tool.html_url}`);
- // console.error('Validation errors:', JSON.stringify(validate.errors, null, 2));

Title:
Issue is #3358 Implement Custom LogService Using Winston for Enhanced Error Logging as suggest by the PR #3265
Description:
As per the discussion in PR #3265 and the request from @akshatnema, this PR implements a custom logging service using Winston to improve error logging throughout the application.
Key changes include:
Configured Winston with custom formatting to include timestamps, log levels, and colorization for better readability.
Introduced multiple transports for logging: console and file-based logs (error.log for errors and combined.log for general logs).
Enhanced log output with additional context, including tool names, URLs, and stack traces, where applicable.
Improved error tracking and visibility in the application.
This implementation ensures that error logs are captured consistently across the application, facilitating easier debugging and issue resolution.
