"Fork" and "Clone" are two terms commonly used in version control systems such as Git to create copies of a repository. Sadly, day in day out, I see people mixup them up.
While they have some similarities, they are not the same thing and have separate purposes. The aim of this article is to clarify the distinction between them as it's crucial for effective collaboration and Repository management.
Git Fork: What does it do?
When you fork a Repo, you are creating an independent copy of it on a hosting platform like GitHub. The forked repo can be modified independently of the original.
This is why Forking is common to Open-Source Development. It lets interested contributors make changes to a project without affecting the original codebase directly.
However, do note that the forked repository maintains a connection to the original codebase for pulling in updates, but it's optional.
When to Fork a Project:
- Contributing to an Open-Source Project:
If you want to contribute to an open-source project hosted on GitHub, forking allows you to create your own copy of the project. You can make changes, experiment, and propose those changes back to the original project by submitting a Pull Request.
- Maintaining a Personal Version:
Fork a repository to create your own version of a specific project that you want to modify extensively or customize for your specific needs. This allows you to have an independent codebase that you can manage separately from the original project.
- Building a Derivative Project:
Forking is useful when you want to build a new project based on an existing one. By forking, you can start with an established codebase and modify it to create a new project while still maintaining a connection to the original project.
Git Clone: What does it do?
Cloning is the process of creating a local copy of a repository on your machine. When you clone a repository, you create an exact replica of the entire repository, including its entire history, branches, and commits.
You can make changes, create new branches, and push your changes back to the remote repository
Unlike Forked Repository, cloned repository is independent of the original repository, and changes made in the clone do not affect the original repository unless you explicitly push those changes.
When you should Clone:
- Personal Development:
If you want to work on a repository locally on your machine without contributing back to the original project, you can clone the repository.
This allows you to have a complete copy of the project's history and work on it independently.
- Collaboration with a Team:
Cloning is commonly used when multiple team members need to work on the same project simultaneously. Each team member can clone the repository to their local machines, make changes, and push those changes back to the remote repository for others to see and incorporate.
- Offline Work:
Cloning a repository allows you to have a local copy of the codebase, enabling you to work on the project even when you don't have an internet connection. You can commit changes locally and push them to the remote repository once you regain internet access.
Forking and Cloning serve different purposes
Forking is typically used for collaborative development, allowing you to create an independent copy of a repository to propose changes back to the original project.
On the other hand, cloning is used to create a local copy of a repository on your machine, enabling you to work independently and make changes without directly affecting the original repository or collaboration with others.
