Publishing local changes

How to push changes to a remote repository using Git.

What's a remote repository?

Until now, the changes you've have made have only been saved to your own computer. If you want others to see the changes you've made, you'll need to upload them to a remote server which is accessible to everyone you want to work with.

This process is called "pushing" your code.

Where can you host your repository?

There are numerous services that let you host your Git repositories. However, here are a number of the most popular services that I'd recommend trying out:

These services let you do all the things you'd expect like:

  • Viewing the files in your project.
  • Displaying a list of recent commits.
  • Showing the changes that happened in an specific commit.

That's not all though! Git hosting providers typically come bundled with a wide range of extra features designed to make working with others much easier.

In this tutorial, I'll walk you through pushing your repository to GitHub because it's the most popular and it's used by the majority of open source projects.

You're more than welcome to use whichever hosting provider you want, however the steps may be slightly different depending on the service you choose.

Creating the remote repository

Once you've registered for a GitHub account and signed in, click the "New" button to create a new repository (or click here).

The repository creation form will look a little something like this:

GitHub Repository Creation Screen

Choosing a name

A repository name is a short name for your project. It can be something as simple as “app”, “blog” or “website”. This name can be changed at anytime in the future, so don't worry if your project doesn't have an official name yet.

Repository descriptions are entirely optional, however it's often a good idea to jot down a simple one-line summary to remind you what the project does.

Public vs. Private

Next, you need to choose between creating a public or private repository.

Public repositories are accessible to everyone. Other developers will be able to freely view your code, see the commit history, and clone the repository to their own computer. Don't worry, they won't be able to freely push changes.

Private repositories are initially only accessible by yourself, however you can invite a limited number of "collaborators" on GitHub's free plan. Developers need the correct permissions in order to view, clone, or push to the repository.

So, which should you choose?

  • Public if you're happy for others to read your code.
  • Private if you'd rather keep your code, well, private.

Note: A public repository can be made private at any time (and vice versa).

The remaining fields

We’re going to be importing an existing repository (from your own computer), so the remaining fields are going to be left blank.

Click on "Create Repository" when you're ready to continue.

Adding the remote repository URL

Once you've created the repository, it's time to add it as a remote and push to it. The empty repository screen GitHub displays after you create your repository actually has a very nice list of instructions.

There are two protocols you can use when working with Git; HTTPS and SSH. If you change the protocol at the top, GitHub will change the instructions below.

GitHub Protocol Selector

Not sure which protocol to use? Check out this article on the GitHub Help site.

Note: Make sure you're in the project's working directory on the command line before proceeding with the next steps.

HTTPS

You'll need to enter your GitHub username and password every time you clone, fetch, pull or push to a remote repository using HTTPS URLs.

To add the remote repository URL, type the following command making sure to replace the HTTPS URL with the one for your own project.

git remote add origin https://github.com/robertlyall/shop.git

SSH

In order to use the SSH protocol, you'll need to generate an SSH key and add it to your GitHub account on the "SSH and GPG keys" page found under Settings.

Once you've done that, type the following command to add the remote repository URL. Make sure you replace the SSH URL with the one for your own project.

git remote add origin git@github.com:robertlyall/shop.git

Pushing your local repository

Once you've added the remote repository URL using you preferred protocol, it's time to actually push you repository to GitHub.

git push -u origin master

A few seconds later, you should see output like this:

Counting objects: 27, done.
Delta compression using up to 8 threads.
Compressing objects: 100% (25/25), done.
Writing objects: 100% (27/27), 44.39 KiB | 6.34 MiB/s, done.
Total 27 (delta 2), reused 0 (delta 0)
remote: Resolving deltas: 100% (2/2), done.
To github.com:robertlyall/shop.git
 * [new branch]      master -> master
Branch 'master' set up to track remote branch 'master' from 'origin' by rebasing.

The -u origin master part of this command essentially links your local master branch with the master branch on the origin remote.

Note: The name "origin" is just a convention used by developers using Git - you don't need to worry about it too much.
