What are the benefits of Git architecture

Have you ever wondered how many cups of coffee it takes to manage the chaos of a multi-developer, and deadline-driven project? It depends on how easy it is for those developers to collaborate to see the project to completion; a process made easier through Git.

You’ve probably heard about GitHub, the version control platform. Over 100 million developers use it to work simultaneously on the same software projects. These developers rely on the same tool to streamline complex workflows, keep track of a jungle of branches, and—most importantly—avoid the nightmare of "final_v2_revised_FINAL" files.

When the power of GIt is harnessed correctly you gain the benefits of a collaboration hub, time machine, logbook and avoid dreaded merge conflict issues which plague software teams everywhere.

Whether you're a solo developer or part of an enterprise team, understanding the Git lifecycle is crucial for effective collaboration and code management. So, let’s take the plunge into Git architecture.

What is Git?

Git is a distributed version control system (VCS) created by Linus Torvalds in 2005 that allows multiple people to work on a project simultaneously. Git is especially useful for tracking changes in source code during software development, but developers use it to manage changes in any set of files.

It allows for collaboration among developers and teams, letting them branch off the main codebase to work on features or bug fixes and then merge those changes into the main project.

Git is the most used version control system according to the Stack Overflow Survey 2022, with 96% of developers using Git as their preferred VCS.

Git works by taking "snapshots" of your files over time and storing those snapshots along with a history. This history includes details about the changes, who made them, and references to parent changes. This way, you can easily roll back to previous versions, compare changes over time, and collaborate with others.

Version control

Version control, also known as source control or revision control, is the practice of tracking and managing changes to a set of files, usually source code, over time.

It allows multiple people to work on a project concurrently, helps resolve conflicts when different parties make modifications and enables users to revert to earlier versions of the work if needed.

Here’s a simple example of how Git works:

Without Version Control:

Alice writes, "Once upon a time, there was a squirrel."
Bob also writes, "The squirrel loved climbing trees."

They both have different versions of story.txt and must manually combine them, which can get messy if the story or codebase is more than a sentence long.

With Git

Day 1: Alice creates a Git repository and writes the first line, "Once upon a time, there was a squirrel."

Day 2: Bob gets Alice's version and adds a second line, "The squirrel loved climbing trees."

Day 3: Alice updates her version, and because they used Git, both changes are neatly combined into one file.

With Git, Alice and Bob can easily combine their work, keeping everything organized and avoiding mess.

The anatomy of Git

Working directory

This is where you do your everyday work on your files. Git does not track changes you make to files in the working directory until you stage them. The .git directory contains the metadata for the repository, such as the commit history, the branch information, and the list of tracked files. The object database contains the actual contents of the files that have been committed to the repository.

Staging area

This is where you put the files you want to commit to the repository. Once you add a file to staging it is considered part of the next commit.

Git repository

Where Git stores all of the committed changes, the repository is a central location where all collaborators can access the project's history.

Git main features

Distributed version control: Unlike centralized version control systems, Git is distributed. Every user has a complete copy of the project history on their local machine, allowing for more flexible and robust collaboration.
Fast operations: Since most operations are performed locally, Git is often faster than centralized version control systems that rely on a network.
Conflict resolution: Git provides tools to resolve merge conflicts manually, allowing users to decide which changes to keep when multiple people edit the same parts of a file.
Commit history: Every commit in Git has a unique identifier (usually a SHA-1 hash), allowing you to easily track changes, revert to previous states, and more.
Strong data integrity: Git uses cryptographic hashing (SHA-1) to ensure data integrity. Each commit and file is checksummed and retrievable based on its hash.
Tags and releases: You can tag specific points in the history as a version, making it easier to track releases and important milestones.
Remote repositories: Git allows you to collaborate online by pushing your local repositories to remote hosting services like GitHub, GitLab, and Bitbucket.
Open source: Git is free and open-source software, meaning it can be modified and distributed under the terms of the GNU General Public License.
Cross-platform: Git is available on multiple operating systems, including Windows, macOS, and Linux, making it versatile and widely accessible.
Hooks and automation: Git has a hooks system, which are scripts that can automatically run when certain events occur, providing a way to automate various tasks.

Benefits of using Git

Remote repository

A remote repository is a copy of your Git repository stored on a remote server. This can be a service like GitHub or GitLab, or it can be an internal server. Remote repositories are used to collaborate with others on projects and can also be used to back up your code.

Distributed architecture

Git can help mitigate some of the challenges of distributed development by allowing developers to collaborate on code without worrying about conflicts. Git also provides a history of all changes made to the code, which can help debug and track down problems.

Track changes

Git allows you to track every change that is made to your code. This makes it easy to see what has changed, when, and who made it. This can be helpful for debugging, reverting to previous versions, and understanding the history of your project.

Collaboration

Git is a distributed version control system, meaning multiple people can simultaneously work on the same project. This is done by each person having their copy of the repository and making changes to their copy. When people are ready to share their changes with others, they can "push" them to the central repository. This makes it easy to collaborate on projects with others, even if they are not in the same physical location.

Backup

Developers can use Git to create backups of your code. This is because Git stores a complete history of all changes that have been made to your code. This can be helpful in case of data loss or corruption.

Version control

Git allows you to create different versions of your code. This can help test new features or roll back changes that have not worked out as planned.

Branching

Git makes it easy to create branches in your repository. Branches are copies of your repository that you can use to work on different features or bug fixes without affecting the main branch. This can help keep your code organized and prevent conflicts.

Merging

Git makes it easy to merge branches back into the main branch. Developers can do it automatically or manually. Merging branches is a common task when working on collaborative projects.

The Git lifecycle

Initialize or clone repository: You start by either initializing a new Git repository with git init or cloning an existing one with git clone.
Staging (git add): To track new files or stage modifications to existing files, you use git add. This moves the files to the "staging area," indicating that you intend to include these changes in the next commit.
Committing (git commit): Once you've staged the changes, you commit them to your local repository with a message describing your actions. This takes a "snapshot" of the staged changes and saves it to the project history.
Pushing (git push): If you are working with a remote repository, you'll often want to share your commits with others. You do this by "pushing" your changes to a remote repository.
Pulling (git pull): You'll want to get others' changes into your local repository. This is done by "pulling" from the remote repository.
Branching (git branch, git checkout): For features, fixes, or experiments, you can create a new "branch" to isolate your changes. This allows you to work independently of the main project line.
Merging (git merge): Once your feature or fix is complete, you merge your branch back into the "main" or "master" branch, integrating your changes into the project.

What is a Git-based headless CMS?

A Git-based Headless Content Management System (CMS) is a type of CMS that utilizes Git repositories as the back-end storage and versioning system for content, while also adopting a "headless" approach to content delivery.

In this model, content is stored in a Git repository and then delivered via APIs or other methods to various front-end interfaces (e.g., websites, mobile apps, IoT devices).

Use Cases

Multi-platform publishing: Ideal for projects requiring content displayed across multiple platforms (web, mobile, IoT).
Headless projects: Great for teams that want full control over the front-end technologies being used.
Collaborative work: Excellent for distributed teams or requiring multiple people to work on content simultaneously.
