HTTP ETag Generator

The `etag` package is a minimalist, RFC 7232-compliant utility for generating HTTP ETags in Node.js applications. It currently maintains a stable version 1.8.1 and has a low release cadence, reflecting its maturity and focused scope. The library supports generating strong ETags for strings and `Buffer`s, and weak ETags by default for `fs.Stats` objects, with an option to override this behavior. Key differentiators include its strict adherence to the HTTP ETag specification, performance optimization for various entity sizes, and a history of robust integration within the `jshttp` ecosystem, often used by popular HTTP frameworks like Express. It prioritizes correctness and efficiency in ETag calculation, having evolved through several hashing algorithm updates to improve security and performance.
