HTTP Cache-Control Header Parser and Formatter (ESM)

cache-control-esm is a JavaScript library specifically designed for parsing and formatting HTTP Cache-Control headers in strict adherence to RFC 7234. Currently at version 1.0.0, this package is a specialized fork of the `@tusbar/cache-control` library. Its primary differentiator is its explicit use of ECMAScript modules (`export default` and named exports), making it well-suited for modern bundlers and environments, especially within projects like `axios-cache-adapter`. Unlike other solutions that may bundle Express/Connect-like middleware or extensive interpretation logic, `cache-control-esm` maintains a narrow focus solely on the low-level parsing of header strings into a `CacheControl` object and formatting such objects back into valid HTTP header values. This focused approach ensures a lightweight and reliable tool for precise Cache-Control header manipulation without unnecessary overhead. Its release cadence is typically reactive to the needs of its consuming projects.
