Code Repository Management
1. Introduction
Code repository management is essential for modern software development, enabling teams to collaborate effectively, track changes, and maintain code integrity. This lesson covers the fundamentals of managing code repositories utilizing version control systems, primarily Git.
2. Key Concepts
2.1 Version Control
Version control systems (VCS) help track changes to code over time, allowing developers to revert to previous versions, compare changes, and collaborate without conflict.
2.2 Repository
A repository (or repo) is a storage location for your project's files, including the entire history of changes made to those files.
2.3 Branching and Merging
Branching allows developers to work in parallel on separate features without affecting the main codebase. Merging combines these branches back into the main branch when work is complete.
3. Repository Setup
3.1 Creating a New Repository
To create a new repository in Git, follow these steps:
git init my-project
This command initializes a new repository in the folder my-project
.
3.2 Adding Files to the Repository
Add files to your repository using the following command:
git add .
This command stages all files in the current directory for the next commit.
3.3 Committing Changes
To save your changes, use the commit command:
git commit -m "Initial commit"
Always provide a meaningful commit message to describe the changes made.
3.4 Pushing to Remote Repository
To push your local changes to a remote repository (e.g., GitHub), use:
git push origin main
Replace main
with your branch name as necessary.
4. Best Practices
- Use meaningful commit messages.
- Commit often to save progress.
- Keep your branches focused on a single task.
- Regularly pull changes from remote repositories to avoid conflicts.
- Document your code and repository structure.
5. FAQ
What is a remote repository?
A remote repository is a version of your project hosted on the internet or another network. It allows collaboration with others and is accessible from multiple machines.
What is the difference between Git and GitHub?
Git is a version control system, while GitHub is a cloud-based platform that uses Git for version control but adds collaboration features.
How do I revert a commit?
You can revert a commit using the command git revert <commit-hash>
, where <commit-hash>
is the identifier of the commit you want to undo.
