What is is-docker?
is-docker is a Node.js package that detects whether the current process is running inside a Docker container. It solves the problem of programmatically determining runtime context, which is useful for applications that need to adjust behavior, logging, or configuration between local and containerized environments. The package provides both a JavaScript API and a CLI tool for easy integration into scripts and workflows.
Node.js developers and DevOps engineers building applications that run in both Docker containers and traditional environments, and who need to automate context-aware behavior.
Developers choose is-docker for its simplicity, reliability, and zero dependencies—it's a focused solution that does one thing well without unnecessary complexity, making it easy to integrate and trust in production systems.
