Git Branches
Git branches are essentially pointers to a snapshot of your project at a specific point in time. They allow you to work on different features or bug fixes independently without affecting the main codebase.
Key Concepts
- Branch creation: Creates a new branch from the current commit.
- Branch switching: Changes the working directory to match the state of a different branch.
- Branch merging: Combines changes from one branch into another.
- Branch deletion: Removes a branch that is no longer needed.
Common Use Cases
- Feature development: Create a branch for each new feature to isolate changes.
- Bug fixing: Create a branch to fix a specific bug without affecting the main codebase.
- Experimentation: Try out new ideas or approaches without risking the main project.
- Collaboration: Different developers can work on different branches simultaneously.
Basic Commands
- Create a new branch:
git branch <branch_name>
- Switch to a branch:
git checkout <branch_name>
- Create and switch to a branch:
git checkout -b <branch_name>
- List all branches:
git branch
- Merge a branch:
git merge <branch_name>
- Delete a branch:
git branch -d <branch_name>
Best Practices
- Frequent commits: Commit changes regularly to preserve your work.
- Descriptive branch names: Use clear and informative names for your branches.
- Keep branches up-to-date: Regularly merge changes from the main branch into your feature branches.
- Review before merging: Carefully review changes before merging them into the main branch.
