Overview of Git

Git is a version control system that takes a snapshot of every change that we make in our codebase. It helps to store the different versions or histories of our codebase.

Let's consider an example: We are developing an appointment booking system for salons. The first version of our booking system is functioning well and is appreciated by the salon owners.

However, they requested a new feature to be added to the system. After making changes to include this new feature, we encountered a bug that caused the booking system to malfunction. Now, we need to revert to the previous version of our app, which was bug-free.

In this scenario, Git becomes invaluable. It allows us to restore that earlier version of our code because it takes snapshots of our code whenever we make changes.

Importance of version control

Git plays an important role in our development. There are many ways in which Git helps us solve our problems.

  • Version Control: Git allows us to track changes in our codebase, making it easy to revert to previous versions if needed.

  • Collaboration: Multiple developers can work on the same project simultaneously without overwriting each other's changes.

  • Branching and Merging: Git enables the creation of branches to work on new features or bug fixes independently, which can later be merged into the main codebase.

  • Backup: By pushing code to remote repositories, Git provides a backup of the codebase, ensuring that work is not lost.

  • History and Documentation: Git maintains a history of changes, including who made the changes and why, which serves as valuable documentation.

  • Code Review: Git supports pull requests and code reviews, allowing team members to review and discuss code before it is merged.

  • Continuous Integration: Git integrates with CI/CD pipelines to automate testing and deployment, ensuring code quality and faster delivery.

  • Conflict Resolution: Git provides tools to resolve conflicts that arise when multiple changes are made to the same part of the code.

What exactly is GitHub?

GitHub is an open-source online platform designed to host our repositories (folders) on the internet. This allows us to access our codebase easily from anywhere at any time.

By hosting our repositories on GitHub, we can take advantage of its powerful features, such as version control, collaboration tools, and integration with various development workflows.

GitHub also provides a web-based interface that makes it simple to manage and review code, track issues, and collaborate with other developers.

Additionally, it supports a wide range of integrations with other tools and services, enhancing our development process and productivity.

Difference Between Git and GitHub

Git is a version control system, while GitHub is a platform for hosting Git repositories. Here are the key differences:

ParametersGitGithub
FunctionalityA distributed version control system that tracks changes in source code during software developmentA web-based platform that hosts Git repositories. It provides a graphical interface for managing repositories, collaboration tools, and integration with other services
UsageUsed locally on a developer's machine to manage code versionsUsed online to store repositories, collaborate with other developers, review code, and manage projects.
FeaturesFocuses on version control, branching, merging, and conflict resolutionAdds features like pull requests, issue tracking, project management, and continuous integration/continuous deployment (CI/CD) pipelines.
AccessibilityRequires installation on a local machine and is accessed through command-line or GUI tools.Accessible through a web browser, providing a user-friendly interface for managing repositories and collaborating with others.
IntegrationCan be integrated with various development tools and IDEs.Integrates with numerous third-party services and tools, enhancing the development workflow.

Getting Started with Git

Let's take a deep dive into how to use Git, a powerful tool for version control. Before we can start using Git, we need to install it on our system. The installation process for Git is similar across different operating systems. Follow the detailed steps below to download and install Git on your system.

Step 1: Download Git

First, visit the official Git website to download the latest version of Git. The website will automatically detect your operating system and provide the appropriate download link.

Step 2: Run the Installer

Once the download is complete, locate the installer file in your downloads folder and run it. The installation wizard will guide you through the setup process.

Step 3: Configure Git

During the installation, you will be prompted to configure some settings. Here are a few important ones:

  • Adjusting your PATH environment: Ensure that Git is added to your system's PATH environment variable. This allows you to use Git from the command line.

  • Choosing a text editor: Select your preferred text editor for Git to use when you need to edit commit messages.

  • Configuring line-ending conversions: Choose the appropriate setting based on your development environment (Windows or Unix).

Step 4: Verify the Installation

After the installation is complete, open your command line interface (CLI) and type the following command to verify that Git has been installed correctly:

git --version

You should see the installed version of Git displayed in the terminal.

Step 5: Initial Setup

Before you start using Git, it's a good idea to configure your user information. This information will be associated with your commits. Run the following commands to set your name and email:

git config --global user.name "Your Name"
git config --global user.email "your.email@example.com"

With Git installed and configured, you are now ready to start using it to manage your code versions, collaborate with other developers, and streamline your development workflow.
