Gherkin Streams is a Node.js library that provides utilities for working with the Gherkin parser using streams. It allows users to parse Gherkin feature files and output structured data (GherkinDocument and Pickles) as a stream of messages, making it ideal for integrating into larger message-processing pipelines. This library is designed for developers building tools or workflows that need to process Gherkin files efficiently, such as test runners, CI/CD systems, or custom BDD tooling.
