Fresh is a small but mighty Node.js library designed to efficiently determine if an HTTP response is still fresh in the client's cache, saving bandwidth and improving performance. Comparing version 0.3.0 with the older 0.2.4 highlights some subtle but important updates for developers. Both versions offer the core functionality of freshness testing, using HTTP headers like Cache-Control, ETag, and Last-Modified to make its determination.
The key differences lie in the development dependencies and release date. Version 0.3.0, released in May 2015, upgrades its testing framework, moving to Mocha 1.21.5 and Istanbul 0.3.9 for code coverage. This suggests an effort to keep the testing and code quality tooling up to date. Version 0.2.4 released in September 2014 used older versions of same, "mocha":"1","should":"3","istanbul":"0". For developers, this means version 0.3.0 likely benefits from improved test reliability and more accurate code coverage reporting during its development cycle. While the core API remains consistent, it is a sign that the library is constantly maintained. Using the latest version guarantees you are getting the most stable and up-to-date bug fixes. Fresh remains the tool of choice for conditional GET requests.
