GitHub Fork and Github Pull Request

A GitHub fork is an essential feature for developers, enabling them to create a personal copy of an existing repository. This new copy, called a fork, allows you to make changes independently without affecting the original project (known as the upstream repository). Forks are integral to collaborative software development, particularly in open-source communities, as they allow anyone to contribute, experiment, or use the existing code base for personal or team projects.

Why Fork a Repository?

There are multiple reasons why you might want to fork a repository on GitHub:

  1. Contributing to Open Source Projects: Forking is commonly used by developers who wish to contribute to an open-source project. By forking a repository, you can make improvements, fix bugs, or add new features without needing permission from the original project owner. Once you are satisfied with your changes, you can submit a pull request to propose incorporating your changes into the upstream repository​(GitHub Docs)​(Data School). If the project owner approves, your contributions will be merged into the main project, helping to enhance the software.

  2. Using Code for Personal Projects: Forking also allows you to reuse code from an existing project in your own work. If a repository contains valuable code that could serve as the foundation for your own project, forking saves you from having to start from scratch. You can modify the code freely to meet your requirements without affecting the original project​(ToolsQA)​(GitHub Docs). This flexibility is especially helpful when the project is large or complex, and you need a customized version for your purposes.

How to Fork a Repository

Forking a repository on GitHub is a straightforward process. Here are the steps:

  1. Locate the Repository: Navigate to the public repository you want to fork.

  1. Click the Fork Button: At the top right of the repository page, you'll find the Fork button. Click it,

GitHub will create a new copy of the repository under your account.

The repository will now appear in your GitHub account dashboard.


  1. Modify the Fork: The forked repository is now fully independent of the original one. You can modify it, add features, or even use it as the foundation for an entirely new project​(GitHub Docs)​(Data School).

Once you've forked the repository, it's important to understand how to manage it.

Working With a Forked Repository

After forking, you'll typically go through these steps to contribute to or use the code:

  1. Clone the Fork Locally: The first step after forking is to clone the repository to your local machine. Cloning makes a copy of the repository on your computer, allowing you to work with the files. This is a Git operation and requires basic Git commands.

     git clone https://github.com/aiwe23/Github_Fork
    

    This command clones the forked repository from GitHub to your local machine so you can begin working​(freeCodeCamp). (Git and GitHub Fundamentals (thirdygayares.com)

  2. Make Changes Locally: Once you've cloned the repository, you can modify the code or files as needed. This is done using your favorite code editor or development environment. You can add new features, fix bugs, or make other improvements​(Data School).

  3. Commit and Push Your Changes: After making changes, the next step is to commit the changes locally and then push them to the forked repository on GitHub.

     git commit -m "docs: add Thirdy Gayares"
     git push origin main
    

    Pushing your changes ensures they are stored in the GitHub version of the repository.


Advantages of Forking

Forking provides numerous advantages in collaborative development:

  • Freedom to Experiment: Forks allow you to freely experiment with the code without the risk of breaking the original project. You can try out new ideas or fix issues without affecting the main project.

  • Collaboration Without Bottlenecks: In larger projects, many contributors can work simultaneously on forks. Pull requests serve as a way to suggest changes and collaborate without needing direct write access to the upstream repository​(GitHub Docs)​(Data School).

  • Learning and Practice: Forking is a great way to learn from existing projects. You can study the codebase, make modifications, and see how changes affect the project without fear of breaking something critical. It’s a safe way to practice coding and working with Git​(Data School).

Forking vs. Duplicating a Repository

It's important to recognize the difference between forking and duplicating a repository. While both create copies of a project, forks are more closely tied to the original repository, especially when it comes to collaboration through pull requests. Duplicating a repository is better suited for cases where you don't intend to merge your changes back into the original project​(GitHub Docs).

Forking is a key feature of GitHub, enabling developers to collaborate, learn, and contribute to projects in an efficient and organized manner. Whether you’re contributing to open-source software or customizing a project for personal use, the fork and pull request workflow provides a clear path to making meaningful contributions without needing direct access to the main repository.

By understanding the forking workflow, you can effectively contribute to or reuse projects, making the development process faster and more collaborative. Mastering forks also deepens your understanding of version control, which is an essential skill for any software engineer.


A pull request (PR) in GitHub is a way to suggest changes to a project. It allows developers to submit their code changes for review and approval before they are added to the main project. Pull requests make it easier for teams to work together, improve code, and track changes.

What Is a Pull Request?

A pull request is when you ask the owner of a project to add your changes to their code. You make changes in your copy of the project and then request to "pull" those changes into the main project. This is a key part of working together on GitHub​(GitHub Docs)​(freeCodeCamp).

  1. Create a Pull Request: If your goal is to contribute to the original project, you need to create a pull request. A pull request is a GitHub feature that allows you to propose your changes to the upstream repository. The owner of the original repository can review your pull request, give feedback, or approve it, which leads to your changes being merged into the upstream project​(freeCodeCamp)​(GitHub Docs).

    Once pushed, you can create the pull request through the GitHub interface.

  1. Syncing Your Fork: As the original project evolves, the upstream repository may receive updates from other contributors. To ensure that your fork stays up-to-date with the latest changes, you need to sync your fork with the upstream repository. This involves fetching the latest changes from the upstream project and merging them into your forked repository. Keeping your fork in sync prevents conflicts when you try to submit new pull requests​(ToolsQA)

IF YOU HAVE EXISTING PULL REQUEST

IF NONE:

Why Use Pull Requests?

  1. Code Review: Other developers review your code to make sure it's correct and efficient.

  2. Team Collaboration: Pull requests help teams work together by providing a space to discuss the changes.

  3. Track Changes: Pull requests record what changes were made and why, which helps keep track of the project’s progress​(ToolsQA).
