There are several features that the GitHub provides in order to handle the distributed code development for the same project, these features are:
1) Public and private repository:
-> With its strong advantage of being fast and Open-source, GitHub provides the repository, where the professionals working on the same project can commit the code from the local machine to the Github and anyone in the team, sitting anywhere can access the code.
-> The administrator of the repository can set the type of the repo, where public means the repository can be accessed by any GitHub user(generally, used for the open source development projects.) and Private repository means the repository can be accessed by only some people who are contributors for that repo assigned by the administrator(which is generally used by most of the IT companies.)
2) The most prudent feature: Version Control and Branching
-> This feature enables team of software developers to manage each of the code changes to the Source code over a period of the time(Version control).
-> Also, there are new feature development requirements where the developers wish to develop them independently without affecting the working source code, branching comes up as a supreme solution, where they can make a branch from the current code and experiment upon them in order to meet customer requirements. Not only this, but branching has another special use-case. Suppose, the code deployed in the environment is found to have a bug. So in this case, developers can easily use branching to fix the bug and can actually merge them into the main branch when the bug is found to have solved in the sub-branch.
-> So, Version Control provides the easy management of the code for the team, while branching provides the individual code development without affecting any other tasks.
3) GitHub also provides several collaboration features like bug tracking, task management, Version History and lots more.
The Community and the Support of GitHub are at the best and so we use GitHub for our daily routine exercises.
-> The github does not provide any testing service.
-> No integration is given to integrate the tasks with commits in order to keep the complete track of the development tasks. Generally, companies use an issue tracking system(i.e., JIRA) to track the development tasks, bugs, development stories and everything, but the developer can't actually directly jump from the task management systems to its source because of lack of integration.
-> Limitations on the file-size: The repository of the GitHub can host information up to 1 Gb and file size cannot exceed 100 Mb.
-> DDoS attack on GitHub was one of the biggest DDoS Attack which happened in around 2018 and thus the data is not so safe because some of the data was leaked although GitHub survived the attack.
-> GitHub is free but for private projects and collabs, they only allow some of the Collaborators while there are other software in the market which allows free for all services for Web-Based Project Hosting.
GitHub is the best platform for Product Based Companies and StartUps to work in an environment where the version of the source code and the development are both synchronized which helps everyone manage the source and the business. GitHub should be used for Bug Tracking and for maintaining the Product's Quality.
Version Control and easily usable terminal for the operations on the branches:
-> Using GitHub, developers and the leads can easily track the changes on the source over the period of time. Adding to this, if there is any task that needs to be done independently without affecting any other version of the code, one can always use branches to develop features and fix bugs. And can also merge them to the original source of the branches to make them error free/updated, GitHub will actually prompt if there's any conflict that needs to be resolved before merging the code.
-> Another plus is, from finding the difference between updated code to committing the new code, everything can be performed using the single terminal of GitHub only. Which also have handy commands to revert, delete, merge the commits for every scenario the developer may face in the whole software development cycle.
