balena-io-modules/dockerignore

This project provides a file filtering library that is fully compatible with Docker's `.dockerignore` file format and exposes the same API as the popular `node-ignore` package for `.gitignore` format. It's a pure JavaScript port of Docker's implementation that works across Linux, macOS, and Windows, with no external dependencies, and is used in production by projects like balena-cli and now-cli. The library is designed for developers building tools around Docker who need to filter files in the same way Docker does during the build process, with support for the unique quirks of `.dockerignore` syntax compared to `.gitignore`.
