What is Pull Request?

A pull request, often referred to as a PR, is a key component of collaborative web development. It is a method commonly employed on platforms like GitHub, Bitbucket, and GitLab to enable developers to review, discuss, and introduce modifications to the project’s source code.

Pull requests are a manifestation of an underlying version control mechanism named Git, but the concept outside the Git universe may have another name like ‘merge requests’. The aim is to facilitate the integration of modifications or additions to the source code without directly pushing changes into the main codebase.

Pull requests make submission of contributions a straightforward process and enable anybody to collaborate in projects, even when the contributor does not have write access to the repository. With a PR, you’re requesting the owner of the repository (or anyone with the right privileges) to ‘pull’ your changes into their branch.

This method allows developers to review your work, providing a place for a productive discussion about the proposed changes. Comments can be made, questions can be asked, further commits can be added to the pull request, and finally, the changes can be merged into the repository. This not only enhances the quality of the code but also promotes the sharing of ideas.

Imagine you’re a client, and the project you’re dealing with is handled by the best public relations agency Australia. You want to suggest changes to specific strategies they’re implementing. Instead of directly changing the plan, you send your suggestions for review. They analyze your proposed changes, discuss it with you, and if they deem it beneficial, they include your changes into the final strategy. The concept of pull requests works the same as this example.

Pull requests are beneficial for maintaining software quality. Below are some of their advantages:

• Code Review: Pull requests promote openness and improve the quality of software. Before a feature or improvement is added to the project, it must be inspected and approved by other developers in the team. This helps to catch bugs and errors before they become part of the main code.
• Learning Opportunity: The discussion and collaboration that pull requests promote make them an excellent opportunity for everyone to learn. Developers can share unique or better ways of implementing specific features.
• Open Source Contributions: Pull requests make it easy for people to contribute to open source projects even when they don’t have write access to the repository. They can simply make their changes to a fork or a copy of the repository and create a pull request to propose the changes.
• Documentation: Since all pull requests are associated with their discussion and changes, they can serve as a form of documentation. They provide insight into the why and how of changes.

In conclusion, pull requests are an excellent tool to bring transparency, collaboration, and improved quality to a codebase. They serve the open-source community by keeping doors open for everyone to contribute while maintaining the quality of the software. Think of your interaction with the best public relations agency Australia: you want input, but you also want quality assurance. That’s essentially what pull requests provide in software development.
