Understanding Branches and Commits

Creating Branches

Branching lets you have different versions of a repository at one time. By default, your repository has one branch named main that is considered to be the definitive branch. You can create additional branches off of main in your repository. Branching is helpful when you want to add new features to a project without changing the main source of code. The work done on different branches will not show up on the main branch until you merge it.

When you create a branch off the main branch, you’re making a copy, or snapshot, of main as it was at that point in time. If someone else made changes to the main branch while you were working on your branch, you could pull in those updates.

1. Click the Code tab of your repository.
2. Above the file list, click the dropdown menu that says main.
3. Type a branch name into the text box.
4. Click Create branch.

Now you have two branches, main and your new branch. Right now, they look exactly the same. Next, you’ll add changes to the new branch.

Making Commits

When you make changes to the files in your repository, you save those changes as commits. Each commit has an associated commit message, which is a description explaining why a particular change was made. Commit messages capture the history of your changes so that other contributors can understand what you’ve done and why.

To create a commit:

1. Make your changes to the files in your branch.
2. Run the command git commit -m "Your message about the commit".

The message at the end of the commit should be something related to what the commit contains – maybe it’s a new feature, maybe it’s a bug fix, maybe it’s just fixing a typo. Clear commit messages are extremely helpful for future programmers who are trying to figure out why some change was made years later.

Merging Branches

Once you’ve finished working on a branch, you can merge it back into the main branch. Merging combines the changes from different branches into one. This is typically used to combine changes made on two distinct branches.

To merge a branch:

1. Navigate to the Pull Requests tab.
2. Click New pull request.
3. Select the branch you want to merge into main.
4. Click Create pull request.
5. Review the changes and click Merge pull request.

Merging branches is a crucial step in maintaining an organized codebase and ensuring that all changes are integrated smoothly.

Working with Pull Requests

Pull requests are the heart of collaboration on GitHub. They allow you to propose changes to a repository, review code, and merge updates seamlessly. Let’s dive into how to work with pull requests effectively.

Opening a Pull Request

Creating a pull request is straightforward. Here’s how you do it:

1. Navigate to the repository and switch to the branch with your changes.
2. Click on the Pull requests tab, then click New pull request.
3. Compare your branch with the main branch to review the changes.
4. Click Create pull request, give it a title, and add a description.

Tip: Pull requests show the differences between branches, making it easy to see what has been added or removed.

Reviewing and Approving Pull Requests

Once a pull request is opened, it’s time for a review. This step is crucial for maintaining code quality and catching potential issues.

• Review Changes: Go through the proposed changes line by line.
• Comment: Leave feedback or ask questions directly on the code.
• Approve: If everything looks good, approve the pull request.

Note: You can request specific people to review your pull request, especially if you’re part of an organization.

Merging Pull Requests

After the review, it’s time to merge the pull request into the main branch. Here’s how:

1. Click Merge pull request at the bottom of the pull request page.
2. Confirm the merge by clicking Confirm merge.
3. Optionally, delete the branch to keep your repository clean.

Remember: Sometimes, pull requests can introduce conflicts. GitHub will alert you if there are any, and you’ll need to resolve them before merging.

By mastering pull requests, you can ensure smooth and efficient collaboration on GitHub. Happy coding!
