How to create and manage project branches in GitLab

1. Introduction
GitLab is a platform for version control and code management, which provides a Convenient interface to create and manage project branches. In team collaboration development, the use of project branches is very important, which can help team members develop independently and maintain code stability. This article will introduce how to create and manage project branches in GitLab, as well as some common operations and techniques.

2. Create a branch
In GitLab, creating a branch is very simple. First, go to the project's main page and select "New branch" in the drop-down menu next to the project name. Then, enter a branch name and select "Create branch."

Sample code:

$ git checkout -b new_branch_name
$ git push origin new_branch_name

The above code will create a branch named new_branch_name and push it to the remote warehouse.

3. Manage branches
In GitLab, you can use a variety of methods to manage project branches, including merging branches, deleting branches, etc.

1. Merge branch
   Merge branch is the operation of merging the modifications of one branch into another branch. In GitLab, you can merge branches by clicking the Merge Request button. First, select the source branch and target branch, fill in the title and description of the merge request, and then click the "Submit merge request" button.

Sample code:

$ git checkout target_branch
$ git merge source_branch
$ git push origin target_branch

The above code will merge source_branch into target_branch and push it to the remote warehouse.

2. Delete branches
   If the work of a branch has been completed, it can be deleted to reduce the number of branches. In GitLab, branches can be deleted by clicking the trash can icon next to the branch name.

Sample code:

$ git branch -d branch_name
$ git push origin --delete branch_name

The above code will delete the local branch named branch_name and delete it from the remote warehouse.

4. Common operations and techniques
When using GitLab to create and manage project branches, there are some common operations and techniques that can improve efficiency.

1. Keep the master branch stable
   The master branch is usually used to store stable code versions, so you should avoid making modifications directly on the master branch during the development process. You can create a development branch, develop and test on the development branch, and then merge into the master branch.
2. Use branches to maintain code traceability
   Code changes can be better traced and managed by creating independent branches for each feature or fix work. Each branch should have a clear name and description to facilitate communication and review by team members.
3. Regularly merge the modifications of the main branch
   In order to keep the branch synchronized with the main branch, you can regularly merge the modifications of the main branch to the development branch. This can prevent the branch from being too different from the main branch and reduce the possibility of merge conflicts.
4. Use tags to manage versions
   When releasing a stable version, you can create a tag for the version. Tags help team members find and roll back to specific versions more easily.

5. Summary
In this article, we introduced how to create and manage project branches in GitLab. We learned how to create branches, merge branches, delete branches, and provide some common operations and tips. By rationally utilizing branch management functions, the efficiency of team collaboration can be improved and the stability and traceability of the code can be maintained.
