node-super-logger - Version 1.1.1 Update

Version: 1.1.1
Package: node-super-logger

Overview

In version 1.1.1, significant updates have been made to the node-super-logger package. The key change is the removal of the npm-scoped package prefix, @amirsohail1/, which has been replaced by the simplified package name node-super-logger. When installing the package, ensure that you use the correct name:

npm install node-super-logger

Additionally, several exciting new features and improvements have been introduced in this release.

Key Changes and Features

1. Package Name Change

• Previous Name: @amirsohail1/node-super-logger
• Updated Name: node-super-logger
• Action: Ensure you install the package using the new name:

  npm install node-super-logger

2. New Feature: HeaderLogger

• A new feature, HeaderLogger, has been added to improve the logging experience.
• HeaderLogger provides detailed insights into HTTP request headers. This will allow you to examine the headers in-depth, including the response headers that are sent to the client.
• This feature is crucial for debugging and ensuring that headers are correctly set for the response sent to the client.

3. Logger Enhancements

• Updated Logger: The logger itself has been updated for improved functionality and ease of use.
• Status Code Logging: The logger now includes the status code of HTTP responses. This makes it easier to track the success or failure of requests, with appropriate logging for different status codes.
  • Example: 200 for success, 400 or 500 for errors.
• Color-Coded Logs: The logger now uses color coding to differentiate between different types of responses:
  • Success: Green color for successful responses.
  • Error: Red color for errors or failure responses.
• This enhancement helps in easily identifying the status of each HTTP request in logs, improving readability and diagnostics.

4. Performance Tracking

• A new metric, Response Time (in milliseconds), has been added to track the performance of your application. This enables you to monitor how quickly responses are being served and identify potential performance bottlenecks.

Summary of Key Changes:

1. Package name change: Use node-super-logger (without the scoped prefix).
2. New HeaderLogger: Log and inspect detailed request and response headers.
3. Enhanced Logger: Now includes status code and color-coded logs for errors and success.
4. Response Time: Logs the time taken for each request/response in milliseconds for better performance tracking.

Conclusion

With version 1.1.1, node-super-logger has become even more powerful by adding key features like detailed header logging, improved logging of HTTP status codes, color-coded logs, and response time tracking. These changes aim to enhance the overall logging and debugging experience while helping you monitor the performance of your application more effectively.

Make sure to update to the latest version and start utilizing these new features for a better logging and performance monitoring experience.
