How does package.json control installation? Where do dependencies go if npm install is not executed or when a project is cloned from Git? Does it offer more than metadata?
The package.json file is central to managing a project’s dependencies and configuration in any NPM project. In my experience, it serves not only as a metadata file but also as a blueprint for how npm sets up and manages dependencies. For instance, when a project is cloned, the package.json file tells developers which modules to install, ensuring consistency across development environments. Additionally, it plays a crucial role in defining project scripts, build configurations, and even specifying the node version. This file is essential for maintaining a predictable and reproducible project setup.
