Dependency Management
Dependency management is the practice of identifying, tracking, and controlling the external libraries, frameworks, and tools that a software project relies on to function. It involves listing dependencies in configuration files (like package.json or requirements.txt), specifying versions, and ensuring consistent installation across development and production environments. This concept is fundamental to modern software development for maintaining project integrity and reproducibility.
Developers should learn dependency management to avoid 'dependency hell' where conflicting or missing libraries cause build failures and runtime errors. It's essential when working on collaborative projects, deploying applications, or ensuring code runs consistently across different machines. Use cases include setting up development environments, automating builds with CI/CD pipelines, and managing security updates for third-party packages.
