A Pull Request (PR) is a core concept in collaborative software development, especially in version control systems like GitHub, GitLab, or Bitbucket. It allows developers to propose changes to a project by submitting a request to merge their code into another branch.
📌 What is a Pull Request?
- Definition: A PR is a mechanism to review and discuss code changes before merging them into the main codebase.
- Key Components:
- Source Branch: The branch containing the proposed changes.
- Target Branch: The branch where changes will be merged (e.g.,
main
ordevelop
). - Code Review: Contributors can comment on specific lines of code.
- CI/CD Integration: Automated tests are often run to validate changes.
🔄 Pull Request Workflow
- Fork the repository (for external contributors).
- Create a new branch for your feature/fix.
- Commit changes and push to your fork.
- Open a PR to the main project repository.
- Collaborators review, suggest edits, or approve the changes.
- Merge once approved and tests pass.
✅ Best Practices
- Keep PRs small: Focus on one task per request.
- Write clear descriptions: Explain the purpose and scope of changes.
- Use code reviews: Encourage feedback to improve code quality.
- Resolve conflicts: Address any merge conflicts before merging.
