Push Git Branch to Remote

You've just finished up a coding session, implementing that exciting new feature your team has been planning for weeks, ready to move that Trello card to done. Your local branch contains all the code, but it's quite similar to the "it works on my machine!" meme - it needs to be shared with the world (or at least your team). This is where pushing your Git branch to a remote repository comes into play, and this tutorial is meant to guide you on how to accomplish this.

The Why Behind Remote Branches

Before we go any deeper, first understand why we need remote branches in the first place. Sarah, a developer I recently mentored, once asked me, "Can't I just keep everything on my machine?" Well, you could, but that would be like writing a novel and keeping it only on your laptop - quite a waste.

Remote repositories serve several crucial purposes:

• They act as a backup of your code
• They enable collaboration with team members
• They facilitate code review processes
• They serve as the source of truth for your project

Prerequisites: Setting Up for Success

Before you can push your branch, you'll need:

• Git installed on your local machine
• A remote repository (like GitHub, GitLab, or Bitbucket)
• Proper authentication set up (SSH keys or credentials)
• A local branch with committed changes

Let's verify your Git remote setup with:

git remote -v

If you're starting fresh, you might need to add a remote:

git remote add origin [email protected]:username/repository.git

In this guide, I am going to cover different scenarios where you'd need to push a branch to remote and how to handle them. So no matter the team or circumstance, you can contribute your bit with confidence.

The Basic Push: Your First Remote Branch

Let's start with the simplest scenario. You've created a local branch called "Login" and want to push it to the remote repository. Here's the command structure:

git push

For example, pushing your 'login' branch to the 'origin' remote:

git push origin feature-login

Real-world Scenario: The Feature Development Workflow

Let me share a real-world scenario. Couple years ago, our team was working on an e-commerce platform, and I was tasked with implementing a new payment gateway. This meant me and my colleagues were contributing to a single repository asynchronously and as such, changes were being pushed frequently. Here's how I managed my branch workflow:
1. First, I created and checked out a new branch: This is to give me an isolated environment to work with, that is not affected by changes my colleagues are constantly pushing.

git checkout -b feature/payment-gateway

2. After making and committing my changes: This adds my changes and commits them.

git add .
git commit -m "feat: Implement Stripe payment gateway integration"

3. Before pushing, I made sure to pull the latest changes from the main branch: Remember I said my branch was devoid of changes from colleagues? Now I want to ensure thatevery new piece of code that have been committed to the repository since I started working on payment integration is pulled into main branch in my local environment. This ensures my main branch and that of the repository are consistent. this prevents conflict when pushing.

git checkout main
git pull
git checkout feature/payment-gateway
git rebase main

4. Finally, I pushed my branch:

git push origin feature/payment-gateway

Advanced Push Scenarios and Common Challenges

Setting Up Upstream Tracking

One common confusion I see among developers is dealing with upstream tracking. Remember Alex, another developer I worked with? (No you don't, It was Sarah I spoke about previously).He kept typing the full push command every time until I showed him this simple trick:

git push -u origin feature-branch

The -u flag (or --set-upstream) creates a tracking relationship so all code push is done to the feature branch by default. After this, you can simply use:

git push

Handling Push Rejection

Sometimes, you'll try to push and get an error like this:

! [rejected] main -> main (non-fast-forward)
error: failed to push some refs to '[email protected]:username/repository.git'

Don't panic! I've been there too. This usually means someone else pushed changes to the remote branch while you were working. Here's how to resolve it:

1. First, fetch the latest changes:

git fetch origin

2. Then, either merge or rebase:

Option 1: Merge

git merge origin/your-branch

Option 2: Rebase (my preferred approach)

git rebase origin/your-branch

3. Resolve any conflicts if they occur, and then push again.
Force Push: The Double-Edged Sword
Sometimes you might need to force push using the "-f" flag:

git push -f origin feature-branch

?? Warning: Force pushing can overwrite remote changes and should be used with extreme caution. I once saw a junior developer(yes, I have seen a lot of developers) accidentally erase a week's worth of team changes with a force push.

If you must force push, use the safer --force-with-lease option:

git push --force-with-lease origin feature-branch

Best Practices and Tips from the Trenches

After years of working with Git, here are some golden rules I live by:

1. Always Pull Before Push

git pull --rebase origin main

2. Use Descriptive Branch Names

Good - 

git push origin feature/user-authentication

Not so good -

git push origin new-stuff

3. Verify Your Target Branch

Check current branch:

git branch --show-current

List all branches and their tracking info:

git branch -vv

4. Clean Up After Merging

Delete local branch:

git branch -d feature-branch

Delete remote branch:

git push origin --delete feature-branch

Troubleshooting Common Issues

Permission Denied

If you see:

ERROR: Permission to username/repo.git denied to user

Check your SSH keys or repository permissions. I recommend running:

ssh -T [email protected]

Wrong Branch Pushed

If you accidentally pushed to the wrong branch, don't worry. Here's how to fix it:

1. Push to the correct branch:

git push origin branch-name:correct-branch

2. Delete the wrong remote branch:

git push origin --delete wrong-branch

Conclusion

Pushing branches to remote repositories is a fundamental Git skill that becomes second nature with practice. Remember, every developer has faced these challenges - I certainly have! The key is to understand the concepts, follow best practices, and learn from mistakes.
Keep this guide handy, and soon you'll be pushing branches like a pro. And remember what I always tell my mentees: "Commit often, push deliberately, and always double-check your branch names!"
Happy coding! ?
