Forking creates a personal copy of a repository under your account, enabling contributions to open-source projects without direct write access to the original repository. As the creator of CoreUI, a widely used open-source UI library, I’ve worked with forked repositories in collaborative development throughout my 25 years of development experience. The most common approach is using GitHub’s fork button to create the copy, then cloning it locally for development. This method establishes the foundation for pull request workflows and collaborative open-source contributions.

Forking creates new Node.js processes that run separate instances of the V8 engine, ideal for CPU-intensive tasks that would block the main event loop. As the creator of CoreUI, a widely used open-source UI library, I’ve implemented process forking in Node.js applications throughout my 11 years of backend development. The most effective approach is using the fork method from the child_process module to spawn Node.js child processes with built-in IPC communication. This method enables message passing between parent and child processes while maintaining process isolation.
