In this lesson, you will learn how to synchronize your local development history with a remote server, ensuring your teammates can access your latest work.
Sharing Your Progress
Up until now, you have been working primarily on your local machine. While your local commits are recorded in your .git history, they remain invisible to the rest of your team. The git push command acts as the bridge between your local repository and the remote server (like GitHub). It takes your local branch’s commit history and "uploads" those snapshots to the corresponding remote branch.
The Mechanics of Pushing
When you are ready to share your work, you use the following syntax:
git push <remote> <branch-name>
For most projects, the remote is named origin. If you are working on your feature-login branch, the command looks like this:
git push origin feature-login
When you execute this, Git performs a "fast-forward" update on the remote server. It sends only the commits that exist on your local branch but are missing from the remote counterpart. If the remote has commits that you do not have, Git will prevent the push to ensure you don't overwrite others' work—a scenario we have learned to resolve by synchronizing our local branches first.
Why Push Frequently?
Pushing is more than just a way to "save" your code; it is a communication tool. By pushing your commits, you allow your team to review your code, run automated tests, and collaborate on the same features. It transforms your individual development process into a team-based workflow, ensuring that everyone remains on the same page.
Remember that git push only uploads commits that you have already finalized with git commit. If you have changes sitting in your staging area or your working directory, they will not be sent to the server until you commit them first.
Key Takeaway: The git push command acts as a synchronization tool that transfers your local, committed history to a remote repository, making your progress available for team collaboration.
