What is a Remote Repository? #
A remote repository is a version of your project that’s hosted on the internet or a network. It allows multiple developers to collaborate, share code, and synchronize changes between their local machines and a central location.
Platforms like GitHub, GitLab, and Bitbucket are popular services for hosting remote Git repositories.
Setting Up a Remote Repository #
1. git remote add origin <url> — Connect Local Repo to Remote #
This command links your local Git repository to a remote one (for example, on GitHub).
Example:
git remote add origin https://github.com/username/project.git
Here:
originis the name of the remote (a common convention).- The URL is the remote repository address.
2. git remote -v — View Connected Remotes #
Displays the list of remote repositories linked to your project.
Example:
git remote -v
You’ll see:
origin https://github.com/username/project.git (fetch) origin https://github.com/username/project.git (push)
Pushing and Pulling #
1. git push — Upload Local Changes to Remote #
Push your commits from your local repository to the remote repository so others can access them.
Example:
git push origin main
This sends your local main branch changes to the remote repository named origin.
If it’s the first push, you can set the upstream branch:
git push -u origin main
The -u flag remembers the remote branch for future pushes.
2. git pull — Fetch and Merge Changes from Remote #
This command retrieves the latest changes from the remote repository and merges them into your current branch.
Example:
git pull origin main
It’s a combination of two actions:
- Fetch: Downloads new commits.
- Merge: Merges them into your local branch.
3. git fetch — Download Changes Without Merging #
Unlike git pull, git fetch only downloads commits from the remote repository but does not merge them into your local branch.
Example:
git fetch origin
You can then view what changed using:
git log origin/main
And manually merge if needed:
git merge origin/main
Working with GitHub #
1. Creating a Repository on GitHub #
- Go to https://github.com
- Click New Repository
- Add a name, description, and select visibility (public/private)
- Click Create Repository
- Connect it to your local Git project using:
git remote add origin https://github.com/username/repo.git git branch -M main git push -u origin main
2. Forking and Cloning #
- Forking: Creates a personal copy of someone else’s repository on your GitHub account.
- Cloning: Downloads the repository (your own or someone else’s) to your computer.
Clone Example:
git clone https://github.com/username/repo.git
3. Pull Requests (PRs) #
A Pull Request is a way to propose changes to a repository. You create a PR to ask maintainers to review and merge your code into the main branch.
Pull Request Workflow:
- Fork or clone the repository
- Create a new branch for your changes
- Commit and push your changes
- Open a Pull Request on GitHub
- Discuss and review changes
- Merge after approval
4. Merging Pull Requests #
Once a PR is approved, it can be merged into the main branch directly from GitHub using the Merge pull request button.
You can also merge locally using Git commands if needed:
git merge feature-branch git push origin main
5. Issues and Discussions #
- Issues: Used to track bugs, improvements, or tasks.
- Discussions: Used for open-ended conversations, feedback, or planning.
These tools improve collaboration and project organization.
6. GitHub Actions (Introduction) #
GitHub Actions allows you to automate workflows such as testing, building, and deploying your code directly from your repository.
Example: Automatically deploy your website when you push changes to main.
Workflow file location:
.github/workflows/deploy.yml
