How to conduct code reviews and merge requests in GitLab

Code review is an important development practice that can help teams identify potential problems and improve code quality. In GitLab, through the merge request (Merge Request) function, we can easily conduct code review and merge work. This article explains how to perform code reviews and merge requests in GitLab, while providing specific code examples.

Preparation:

1. Please make sure you have created a GitLab project and have the appropriate access permissions.
2. Please make sure you have installed and correctly configured a Git client (such as Git Bash).

Step 1: Create a branch
Before conducting code review, we need to create a new branch first so as not to affect the main branch.

1. Open the GitLab project page and click the "Repository" tab.
2. In the "Branches" section on the right, click the "New branch" button.
3. Enter a new branch name, such as "feature-branch", and then click "Create branch".

Step 2: Clone the project
Now we need to clone the project locally for development and code modification.

1. Open your Git Bash or any terminal tool.

2. Run the following command to clone the project locally:

   git clone [项目URL]

   Please replace [project URL] with the URL of your GitLab project.

3. Switch to the newly created branch:

   git checkout feature-branch

Step 3: Make code modifications
Develop and modify the code in the local copy , such as adding new functionality or fixing bugs in a certain file of the project.

Step 4: Submit changes
After completing the code modification, we need to submit the changes to GitLab for team review.

1. Run the following command to view your modification status:

   git status

2. Run the following command to add the change file to the staging area:

   git add [文件名]

   Please replace [file name] with the name of the file you modified, or if you want to add all changed files, you can use the following command:

   git add .

3. Run the following command to commit Change:

   git commit -m "描述提交的变更"

   Please fill in the description of the change you submitted in double quotes.

4. Run the following command to push the commits to the remote repository:

   git push origin feature-branch

   Be sure to replace "feature-branch" with the name of the branch you created.

Step 5: Create a merge request
Now we can create a merge request to let team members review your code changes.

1. Return to the GitLab project page and click the "Merge Requests" tab.
2. Click the "New merge request" button.
3. Select your branch (e.g. "feature-branch") in the "Source branch" drop-down menu.
4. Select the target branch to merge to (usually the master branch) in the "Target branch" drop-down menu.
5. Fill in the title and description of the merge request. This information will help reviewers understand your changes.
6. Click the "Submit merge request" button.

Step 6: Code review and discussion
Your merge request has now been created, and team members can review your code, propose modifications, and discuss it in the discussion area.

Step 7: Merge Changes
Once your merge request passes the team's review and discussion, and meets the project's requirements and standards, your changes will be merged into the target branch.

1. Open the GitLab project page and enter the "Merge Requests" tab.
2. Find your merge request and click the "Merge" button.
3. Confirm the target branch to be merged, and fill in the title and description of the merge request.
4. Click the "Merge" button to merge.

Finally, your changes have been successfully merged into the target branch, and your code changes will be included in the latest version of the project.

Through the above steps, you can conduct code reviews and merge requests in GitLab. This process helps teams improve code quality, reduce issues, and promote collaboration and knowledge sharing. I hope this article's detailed code examples are helpful.
