Learn about GitHub's merge project function

GitHub is the world's largest code hosting website. People often use GitHub to manage their own code. Project development often involves multi-person collaboration, with different people developing different functions in different time periods, and these functions will be integrated into the same project. At this time, how to integrate different functions into one project becomes particularly important. This article will introduce you to GitHub's merge project function, and explain in detail how to use this function to manage the code in the project.

1. How to merge projects

When using GitHub to manage projects, code merging is done through Pull Request. Pull Request means that GitHub users send a request to users who own the code base or branch to review the update before pushing the current code update to a branch of the code base. In this Pull Request, in addition to containing code updates, it will also contain some information, such as the purpose of the update, a detailed description of the update, etc. This information will be submitted to the manager.

After the branch is established, team members carry out their own work. When a team member completes a certain work and needs to merge the work results into a branch, he needs to submit the code to his own branch first, and then initiate a Pull Request. After reviewing the code, the manager can choose to accept the merge request, at which time the code of the branch will be merged into the main branch.

2. Operation steps for project merging

Before introducing the project merging function of GitHub, we need to first learn how to establish a branch in GitHub. The specific operations are as follows:

1. First, click the drop-down menu of "Branch: master" on the project homepage and select "New branch" from it.
2. Enter the branch name in the pop-up box, and then click "Create branch".

Now that we have created the branch, we can start to talk about how to merge the projects. The following are the steps to merge projects:

1. First, select the code library you want to merge in your own code library, and submit the code to the manager through Pull Request.
2. After the manager reviews the code, he or she can choose to accept the merge request or reject it. If the merge request is accepted, the code will be merged into the main branch.
3. Next, the manager needs to merge the submitted code into the main branch locally and use the git pull command to pull the latest content. If there are conflicts, they need to be resolved manually.
4. After modifying the code, submit it to the remote branch again. When submitting, you need to specify the submission information, which contains the content of this submission.
5. After submitting again, you can view the modified file list on the project homepage, and these files will be automatically merged into the main branch.

3. Common problems and solutions

1. Code conflicts may occur during the merge process, and conflicts need to be resolved manually. After resolving the conflict, follow the steps above.
2. The merged code is incompatible. In this case, the merged code needs to be checked in detail to ensure that the merged code can run normally.
3. An error code occurs. In this case, you can use git revert to roll back the code. After rolling back the code, it needs to be committed to the master branch.
4. If the member does not issue a Pull Request after completing the code update, the manager cannot complete the code merge. Therefore, team members need to be reminded to make Pull Requests in a timely manner.

To sum up, using GitHub’s merge project function can make multi-person collaborative development smoother. Creating a better collaborative environment is also more conducive to ensuring the stable operation of the project. It's important to note that any changes will directly affect the code base, so you need to exercise caution when merging code. I hope this article is helpful to everyone, keep up the good work.
