A repository, or repo, is a centralized digital repository that developers use to make and manage changes to the source code of a program. When developing software, developers need to store and share folders, text files, and other types of documents. Repositories have features that allow developers to easily track code changes, edit files simultaneously, and collaborate effectively on the same project from any location.
Why is repo important?
Repos allow software development teams to make numerous changes to the program code of a software application without affecting the underlying source code. Instead of applying the changes directly to the main branch, they use features in the repository to edit and review the changes. This reduces merge conflict when two or more developers edit the same piece of code.
Developers also use repositories to introduce new features or fix bugs without affecting the working version of the application. They create a new branch or copy of the original source code as a local repository to work from. This way, developers ensure that new changes are properly tested before they are released to customers.
Benefits of repo for business
Companies become more flexible and responsive to changing consumer demands when they use repositories for application development. Developers can quickly work on new features without affecting the stability of the active application. Repos allow developers to make changes and quickly resolve potential issues. Organizations can also coordinate application development tasks between developers working remotely.
What is a GitHub repo?
GitHub is a cloud-based repository that allows developers to store and work on project codes in an organized manner. GitHub is built on Git, a version control system, and includes additional features that improve collaboration between developers. It provides a graphical user interface that makes it easy to use the repository’s features.
GitHub has also become an online open source community for developers. Developers can communicate with colleagues by joining discussions, offering help, and contributing their expertise to public projects on GitHub.
How does a GitHub repo work?
A GitHub repository allows developers to collaborate remotely and in a distributed manner using a locally installed version control tool. Developers use a command line interface to implement functions in Git, a version control software.
Git allows developers to create, manage, and merge code changes with the main source code.
Create
First, developers create a new repository in the project directory that contains the code files. Alternatively, they can clone a Git repository from an existing one. A Git repository typically contains a README file that displays information describing the project.
Customize
Before making changes to a local repository, developers set up a repo by adding information such as a username and email address. This allows collaborators to identify the author of a particular Git repository. The developer can then make changes to the code and commit it using the git commit command.
Change
Developers make changes to the code in their repo. Initially, changes are only saved on the local system. When they are ready, they can merge the changes into a central repo. If another developer changes the same file, they can manually review and resolve any conflicts.
