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 or develop).
    • Code Review: Contributors can comment on specific lines of code.
    • CI/CD Integration: Automated tests are often run to validate changes.

🔄 Pull Request Workflow

  1. Fork the repository (for external contributors).
  2. Create a new branch for your feature/fix.
  3. Commit changes and push to your fork.
  4. Open a PR to the main project repository.
  5. Collaborators review, suggest edits, or approve the changes.
  6. 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.
