Express Bunyan Logger Middleware

express-bunyan-logger is an Express middleware that integrates the Bunyan structured logger into web applications. It automatically logs incoming requests and outgoing responses, enriching log entries with detailed metadata such as HTTP method, URL, response status, and response time. It supports flexible configuration for log formats, custom levels based on response status or time, and dynamic inclusion/exclusion of fields. The current stable version is 1.3.3, last published 8 years ago. However, the project's original maintainer has openly stated a lack of time for ongoing maintenance, indicating an effectively abandoned status. While functional, new feature development and proactive security updates are unlikely. Its primary differentiator is deep integration with Bunyan's serialization capabilities, providing rich, machine-readable logs suitable for analysis and integration with log management tools.
