If you’ve started coding, you’ve probably heard a lot about Git and GitHub, be it on forums, conversations with other coders, tutorial videos, or even instruction manuals. If you’re a beginner, they may sound a bit too similar. So what’s the difference between Git and GitHub? Which one should you use? Let’s try to clear up the confusion.
What Is Git?
Linus Torvalds, whom you might know as the creator of Linux, created Git, a distributed version control system, in 2005.
Version Control
So what is “version control?” Well, it’s a method of tracking changes in code so you can go back to previous versions if something goes wrong. Think of it as a sophisticated “Undo” button for the entire project. Git saves different versions of your project as you work on it. If you make a mistake, you can revert to a previous version and restore the code to exactly what it was at that specific point.
Branching and Merging
You can create branches with Git to work on new features or fix bugs and the source will stay the same. Once you’re done and happy with the final changes, you can merge these branches back into the main project. It’s a neat way to organize the work and keep things in testing separate until they’re ready.
Distributed System
Every developer working on a project has a full copy of the repository, including the entire history. Therefore, you can work offline and still have access to all past versions of the project. They’re all safe and sound on your machine.
Why Use Git?
Git is perfect when you want to manage project history. You can keep track of all the changes that make or break your code and it lets you go back whenever you need to, for debugging, or just to try something else. So, in simpler terms, Git is a complete, very in-depth diary of your code. It’s especially useful if you’re working solo or in a team where members work on different parts of the project at different times.
What Is GitHub?
Now, from Git you get to GitHub, and there’s a reason they sound similar. GitHub is an online platform built around Git. It hosts your Git repositories online and adds a suite of collaborative features. Think of GitHub as something bit like a social network for developers. It makes it easy to share code, collaborate with others, and manage projects. That’s the “hub” part of GitHub. It isn’t actually a competitor to Git. It’s an implementation of it in a community hub manner.
Repository Hosting
GitHub hosts your code in the cloud, so it’s accessible from anywhere at all times. This is great for remote teams and for accessing your projects from different devices.
Collaboration Tools
Some cool GitHub features include pull requests, issues, and project boards. When dev teams work together, they use these features to do the job more cleanly, track progress, and discuss changes.
Community
The main appeal of GitHub is that you can share projects with the world. Other developers can contribute to your code, and you can contribute to theirs. It’s a fantastic way to learn from others and improve your skills.
Why Use GitHub?
The keyword that sums up GitHub as a whole is collaboration. It makes working with others easy and keeps your projects organized. It’s also excellent for showcasing your work to potential employers or collaborators. If you want to build a professional portfolio, GitHub is the place to do it.
Git vs. GitHub
Now that we know what Git and GitHub are, let’s compare them directly.
Purpose:
- Git manages the code’s version history.
- GitHub hosts Git repositories (so, those version histories) online and gives you tools for collaboration and project management.
Operation:
- Git runs locally on your computer. You don’t need to go online to use it.
- GitHub lives online. You need a connection if you want to use it.
Use:
- Git is best for tracking changes and managing project history.
- GitHub is best for collaborating with others and sharing work.
When to Use Git
If you’re working on a project alone, like privacy while coding, don’t like relying on the cloud, or your team prefer to work on separate timelines, Git is the way to go. You can still track changes, create branches, and merge them back just as you would on GitHub, but it all exists offline and no one else gets to see it.
Solo Projects
Git helps you manage solo projects excellently within your local, familiar environment. You can create branches for new features and merge them back when you’re ready, without anyone else interfering. This way, your main project stays clean and functional until the new feature is fully ready for integration.
Offline Work
Git’s distributed nature means you can work offline. You don’t need to worry about a constant or stable connection to make changes and commit them to your project, or whether or not something in the cloud may interfere with your pulls. If you’re traveling or live somewhere with a spotty connection, this feature is even more convenient for you.
When to Use GitHub
Where GitHub shines is in collaborative environments. If you’re working with a team or contributing to open-source projects, you’ll want to use it in order to cooperate and keep contributing. You can also keep tabs on the development of various open-source projects you might be interested in.
Team Collaboration
GitHub’s features, like pull requests, issues, and project boards, help teams work together. You can assign tasks, review code, and discuss changes all in one place. When everything is easy to find and everyone’s on the same page, miscommunication is less likely and everyone should feel like an integral part of the team.
Open-Source Contributions
GitHub is the hub (again, hence the name) for open-source projects. It’s easy to fork repositories, make changes, and submit pull requests. So, contributing to other projects is really simple and rewarding. Plus, it’s a great way to build your reputation and get your name out there among other developers.
Using Git and GitHub Together
While Git and GitHub serve different purposes, they complement each other perfectly, so use them together.
- First, you need to install Git on your computer. It’s free and you can get it for Windows, macOS, and Linux.
- Once you have Git, sign up for a free GitHub account if you don’t have one already.
- Use Git to initialize a repository on your PC.
- Link a local repository to a GitHub repository and push your changes.
Here’s an example of how you might work with these two:
- Use Git to create a new branch for a feature you’re working on. It’ll keep your changes separate from the main project until they’re ready.
- Write your code and commit changes to a branch. Each commit is a snapshot of your project at that point in time.
- Push your branch to GitHub. When you push a branch, it uploads your changes to the cloud, making them accessible to your team.
- On GitHub, open a pull request to merge changes into the main branch. That way, your team (or anyone who might want to contribute) can review your work before it becomes a part of the project.
- Collaborate with the team to review the changes and merge them into the main branch. So, only high-quality, well-reviewed code makes it into the main project.
Benefits of Using Both
Using Git and GitHub together is the best of both worlds. You get powerful version control for Git and the collaboration tools of GitHub.
Version Control
With Git, you have detailed control over your project’s history. You can create branches, merge them, and revert changes when you feel it necessary. That’s great for a tidy project and, better yet, prevents mistakes.
Collaboration
GitHub makes it easy to work with others. Everyone can manage projects, review code, and keep everyone else on the same page. Therefore, your team will talk to each other and share their knowledge easily and no one will be confused.
Alternatives to GitHub
While GitHub is the “top dog” in cloud version control, it’s not the only one that Git repositories. Do you need alternatives?
GitLab
GitLab has similar features to GitHub but with some differences. It includes built-in continuous integration (CI) and continuous deployment (CD) tools. GitLab also provides more nuanced user permissions, which can be good for larger teams.
Bitbucket
Bitbucket is another platform for hosting Git repositories. It integrates with Jira: good for teams already using Atlassian tools. Bitbucket offers both Git and Mercurial repositories, providing some flexibility in your choice of version control systems.
The Battle of Gits
There’s no real winner in the battle of Git vs. GitHub because they serve different purposes. Both are incredibly useful, but they shine in different areas. Git is your go-to for version control and managing your project’s history. GitHub is perfect for collaboration, project management, and showing off your work.
Alone or with a team, Git and GitHub complement each other beautifully, making it easier to manage your code and work with others.
