GitHub-Flow Branching Strategy
Inspired by the development practices at GitHub, GitHub-Flow is a simplified and streamlined branching model designed for agility and continuous delivery. Unlike Git-Flow, GitHub-Flow revolves around a single main branch, typically ‘master’ or ‘main,’ and leverages pull requests for collaboration.
Key Branches:
- Main:
- Represents the production-ready state of the project.
- All development work is done directly in this branch.
Workflow:
- Initialization:
- Initialize the repository with a main branch (e.g., ‘main’).
- All development work, feature additions, and bug fixes happen on this branch.
- Start a New Feature:
- Create a new branch for the feature directly from ‘main.’
- Develop the feature and open a pull request when ready.
git checkout -b feature/branch
# Work on the feature
git push origin feature/branch
- Open a Pull Request:
- Create a pull request to merge the feature branch into ‘main.’
- Collaborate, discuss, and review changes before merging.
- Continuous Integration (CI):
- Leverage CI tools to ensure the proposed changes don’t break the build.
- Merge to Main:
- Once the pull request is approved, merge the changes into ‘main.’
- Deployment:
- Deployments can be triggered automatically from the ‘main’ branch to production.
Pros and Cons:
Pros:
- Simplicity:
- A straightforward and easy-to-understand branching model.
- Continuous Delivery:
