Mastering Git for Web Development: Complete Guide for Beginners


Introduction

Have you ever experienced starting a computer project, whether it's writing a document in a text editor, editing an image in an image processing software, or working on an Excel spreadsheet... and then losing everything due to a false “manipulation” or because your computer broke or got stolen 😭?

Now, imagine if it were about a program that you spent several days, even weeks, coding!

Losing everything overnight from an important project is extremely frustrating πŸ˜–.

For this reason, Linus Torvalds, a computer pioneer previously discussed in the course “The Job of a Web Developer” at “The Web Developer's Job”, created THE solution for this: Git.

Git is a version control tool, meaning it can record ⬇️ each code modification you make and, when coupled with Github πŸ™, store it in the Cloud to never lose your code again.

Let's see how to use this wonderful tool and all the key features it offers for developing modern applications.

Over time, this tool has become essential in the development ecosystem and has become a MUST-HAVE tool to master for becoming a professional Developer πŸ€“.

Thanks to this article, you will master the basics of Git and Github, making yourself a much more seasoned Developer πŸ’ͺ!

Git: The Key to Success in Modern Web Development

In addition to warning you of a potential loss of your work on your program, Git will allow you to manage different code versions when working in a team πŸ‘₯ on the same program.

As we discussed in the course on The Job of a Developer, developers are increasingly working in teams, and before Git, it was a real puzzle 🀯 to reconcile the work of each developer working on the same codebase.

Git has been a real revolution in this field, isolating the work of each developer and providing a way to easily add each developer's work to the codebase, avoiding introducing bugs πŸ‘Ύ.

Let's get practical πŸ§‘β€πŸ’»!

πŸ›  Getting Started with Git & Github

Entering the world of Git begins with a few steps:

  1. Install Git.
  2. Sign up for a Git Cloud.

Creating an account on platforms like GitHub or Bitbucket is your first step towards a collaborative development ecosystem.

Github is not just a Cloud for your code but also a social network πŸ‘₯, so once registered, feel free to follow me:

Installing Git on your machine marks the beginning of your version control journey.

On Linux 🐧

If you are using Linux, installing Git is simple.

Open a Terminal and enter the following command:

sudo apt install git-all

The package utility will take care of installing all Git dependencies, making it ready to use on your computer.

On Mac 🍎

If you are on Mac, first check if Git is already installed by running the command:

git --version

If Git is not installed, the utility will guide you through the installation process.

On Windows πŸ–₯️

For Windows users, the process is slightly different. Download and install Git from the official site Git.

Once the installation is complete, you will be ready to dive into the world of Git and optimize your development workflow.

Git comes with built-in GUI tools for staging (git-gui) and browsing (gitk), but there are also several third-party tools for users looking for a platform-specific experience.

πŸ”§ Using Git

The daily use of Git transforms the way you approach software development.

Add Files πŸ“‚

When you start a new project with Git, the first step is to initialize a Git repository in your project directory.

For that, use the command:

git init

This command creates a new Git repository, thus initiating the tracking of changes in your project. It marks the starting point of your version history.

Add Changes πŸ”„

Once your repository is initialized, add all files in your project with the command:

git add .

This step prepares your changes for the next commit.

Make the First Commit 🚩

After adding your files, create your first commit  using the command:

git commit -m "First Commit"

This records your changes with a descriptive message, establishing a state in the history of your project.

Push Your Changes πŸ”—

To share your progress with a remote repository, use the command:

git push

This action pushes your commits to the remote repository, allowing other team members to access your latest contributions.

Each Git command is a step towards a more structured and transparent project management, opening the door to unprecedented development possibilities.

πŸ”€ Branches and Merging in Git

The power of Git lies in its ability to manage multiple lines of development through branches.

Creating branches for new features 🌟, bug fixes πŸ›, or even experiments πŸ§ͺ allows developers to work in isolation without disrupting the main codebase.

Create a New Branch 🌿

Use the following command to create a new branch in your project:

git branch your_branch_name

This establishes an isolated environment where you can make changes without affecting the main branch.

Switching Between Branches πŸ”„

The command “git checkout” allows you to switch between branches.

For example, to switch to the new branch you just created:

git checkout your_branch_name

This puts you in your new branch, ready to make specific changes without disrupting work on other features.

Once a feature is ready in a specific branch, the “git merge” command facilitates the seamless integration of changes, preserving the overall integrity of the project.

Merging Branches πŸ”„

To merge a branch with the main branch (usually main or master), use the following command:

git merge your_branch_name

This combines the changes from the specified branch into the current branch, ensuring a smooth integration of new features.

🀝 Conflict Management

Conflicts arise when there are conflicting changes in the same code segment.

Git not only reports these conflicts but also provides tools to effectively resolve them.

Using “git mergetool” allows developers to resolve conflicts manually and understand the design choices behind each line of code, strengthening team cohesion and software quality.

βœ… Commit Strategies and Gitflow

Adopting a consistent commit strategy for maintaining a clear project history.

Clear commit messages and atomic commits (each commit represents a single and well-defined change) make it easy to navigate the project history.

Gitflow

The Gitflow model, with dedicated branches for features, fixes, and releases, optimizes the development process and helps manage software versions more predictably.

GitHub Flow

This is a Git-based workflow model that simplifies the development process by focusing on rapid iteration and continuous delivery.

Unlike more complex models, GitHub Flow focuses on a main branch  (usually main), simplifying the management of features, fixes, and releases.

These approaches promote smooth collaboration and allow for more predictable software version management, making the development process more agile and efficient.

πŸ”„ Pull Requests and Code Review

Pull Requests (PRs) on platforms like GitHub or GitLab transform the code review process.

By inviting the team to review changes before integration into the main branch, PRs encourage collaboration, improve code quality, and reduce the risk of errors.

Code reviews become opportunities for learning and knowledge sharing, essential for professional development.

πŸ” Security with Git

In a world where software security is more important than ever, Git offers several features to protect your code.

The use of SSH (Secure Shell Protocol) for communications, signing commits with GPG (GNU Privacy Guard) to verify the author's identity, and branch protection policies are measures that strengthen the security of your web projects.
