Master Git Push and Pull: The Guide Every Developer Needs!

Git can be a developer’s best friend, but it’s not always that way. We’ve all been there: madly Googling “how to undo a git push” at 3 a.m., wishing we’d paid more attention in that Git learning experience.

But don’t worry, this blog is here to help you avoid future Git-related panic attacks.

Today, we’re going deep into the field of Git push and pull commands. These essential tools can make or break the way you work.

By the end of this blog, you’ll not only understand the complex nature of these commands, but you’ll also have learned many handy strategies that will make you look like a Git expert (without the lengthy beard).

Understanding The Basics

What Exactly Is A Git Push?

Let me start with the basics.

When you perform git push, you are telling Git to send your local changes to a remote repository, often GitHub or Bitbucket.

Consider sending your latest work to a gathering spot where everyone on your team can access it.

Common Scenarios:

• Pushing code updates to a shared repository.
• Sharing the latest features with the team.
• Update the remote branch with your changes.

What Is Git Pull?

Now, git pull is the command for getting the most recent changes from a remote repository and merging them into your local branch.

It’s similar to downloading the most recent version of a document from the cloud to ensure you’re working on the most recent draft.

Common Scenarios:

• Syncing your local branch to the remote.
• Before starting any work, check that your local copy is updated.
• Integrating others’ changes into your branch.

What’s The Difference Between Git Pull & Fetch?

This is when things become a little challenging.

While git pull automatically pulls and merges changes, git fetch just downloads the changes and leaves it up to you to decide what to do next.

Think of git fetch as a careful leader, providing information without making assumptions about it, whereas git pull is a go-getter who tries to do everything at once.

When to Use Pull vs. Fetch:

• Use git fetch to check out changes before merging.
• When you’re ready to add and merge changes, use git pull.

Best Practices for Git Push

Use Branches Carefully

Ever pushed to the wrong branch and caused chaos? It’s a rite of passage for developers.

Avoid this by following a few simple rules:

• Branch Naming Conventions: Keep branch names valuable and simple. For example, feature/login-page and bugfix/header-alignment.
• Double-Check Before Pushing: Always double-check which branch you’re on before pushing. Keep yourself safer than having to explain to your team why you mistakenly launched a half-finished feature to production!

Handling Merge Conflicts

Merge conflicts are the annoying in-laws of the coding world — unavoidable but solvable.

Here’s how to handle them like a pro:

1. Predict conflicts: If many people are working on the same file like open-source, be ready for conflicts.
2. Handle with attention: To carefully mix changes, use tools such as the merge conflict editor in VSCode or Git’s command line tools.
3. Test After Resolving: Always test your code after resolving issues. You don’t want to push bad code!

Pushing Tags & Releases

In Git, tags work similarly to bookmarks in your code’s history.

They are essential to finding launch points or versions.

• How To Push Tags: To push tags to the remote, run git push origin.
• Importance Of Tagging: Tags help to keep track of releases, making it easy to reverse if something goes wrong.

Mastering Git Pull

Understanding Fast-Forward & Merge Pulls

When you git pull, Git can merge changes in different ways:

• Fast-Forward: If your branch has not separated from the remote, Git simply updates the branch pointer.
• Merge: Git combines commits that contain diverging changes, which can lead to conflicts.

How To Control Pull Behavior:

• Use git pull--rebase to clear up the history, or git pull-- no-ff to force a merge commit.

Using Git Pull With Rebase

Rebasing is like giving your commits a makeover, making them appear as if they were created in a perfectly linear order.

• Benefits: A clean, linear history that’s easier to follow.
• How to Pull with Rebase: Run git pull --rebase instead of the regular git pull to apply your changes on top of the latest from the remote.

Handling Conflicts On Pull

To avoid conflicts, communicate with your team. If conflicts do happen:

1. Review Conflicts: Carefully examine the conflicting files.
2. Resolve and Test: Fix conflicts and test your code to make sure everything works as expected.

Advanced Tips & Tricks

Force Pushing: When & How To Use It

git push --force is the nuclear option — powerful but deadly. It has the potential to erase history, so use it carefully.

• When to Use: Only rewrite history when truly needed, such as to fix an already-pushed wrong commit.
• Safer Option: git push -- force-with-lease is a safer option as it stops you from replacing others’ work.

Working With Many Remotes

Have lots of remotes? Not a problem! You can push and pull from many remotes, like a Git hacker.

• Practical Example: git push origin main sends to your primary remote, however git push upstream main can be sent to a collaborator’s remote.

Using Git Stash Before A Pull

Sometimes you’re in the middle of something and need to make changes. Instead of committing unfinished work, stash (save) it!

• How to Stash: git stash save "WIP" saves your work in progress.
• Applying Changes: After pulling, use git stash pop to apply again the changes you made.

Git Hooks For Push & Pull

GitHub Webhooks 101: Stop Refreshing, Start Reacting (For Developers)

The blog shared above offers a full overview of what git hooks are and how they work.

Git hooks are scripts that perform automatically when particular Git events happen.

Consider them to be your small helpers.

Common Mistakes & How To Avoid Them

• Pushing To the Wrong Branch: Prevent this by turning on branch protections and carefully checking where you’re pushing!
• Not Pulling Before Pushing: Make a habit of pulling before pushing to avoid future conflicts. You can even alias git push to need a pull first!
• Ignoring Push Failures: When a push fails, explore the root cause rather than just repeating the command. Review the logs and find the root cause.

Final Words

You should now have a solid knowledge of the Git push and pull commands, as well as some advanced strategies to help your workflow run more smoothly.

Remember, Git is your buddy, but like any friendship, it takes some work and understanding.
