Do you want to collaborate on code in GitLab? If so, you need to learn how to create a merge request. A merge request is a way to propose changes to a code base and get feedback from other developers. It can help you keep your code base up-to-date and avoid merge conflicts.
In this blog post, we will show you how to create a merge request in GitLab in 2023. We will guide you through the steps of creating a merge request, including what information to include and how to review it. Whether you are a beginner or an expert, you can use this tutorial to create a merge request in GitLab.
What is a merge request?
A merge request is a request to merge one branch of code into another branch. A branch is a copy of the code that you can modify without affecting the original code. You can use branches to work on different features or bug fixes without interfering with each other.
A merge request allows you to compare the changes you’ve made in your branch with the original branch and see if there are any conflicts or errors. You can also invite other developers to review your merge request and give you feedback or suggestions. Once your merge request is approved, you can merge your branch into the original branch and update the code base.
How to create a merge request
To create a merge request in GitLab, you need to have a project and a branch that you want to merge. You also need to have access to the GitLab web interface or the command line. Here are the steps to create a merge request in GitLab:
- Go to your project page on GitLab and click on the “Merge requests” tab.
- Click on the “New merge request” button.
- Select the source branch and the target branch that you want to merge. The source branch is the branch that contains your changes, and the target branch is the branch that you want to merge into.
- Click on the “Compare branches and continue” button.
- Enter a title and a description for your merge request. The title should summarize what changes you’ve made, and the description should explain why you’ve made them and what tests you’ve run.
- Optionally, you can assign your merge request to someone, add labels, milestones, or reviewers, or enable squash commits or delete source branch options.
- Click on the “Submit merge request” button.
Alternatively, you can create a merge request from the command line using the
git push command with the
-o option. For example, if you want to create a merge request from your
feature branch into the
main branch, you can run:
git push -o create_merge_request -o target_branch=main origin feature
This will push your
feature branch to the remote repository and create a merge request with the
main branch as the target.
What to include in a merge request
A good merge request should include enough information for other developers to understand what changes you’ve made and why. Here are some tips on what to include in a merge request:
- A clear and concise title that summarizes what changes you’ve made.
- A detailed description that explains why you’ve made these changes, what tests you’ve run, and what issues or bugs you’ve fixed or addressed.
- A link to any related issues or tickets that your merge request resolves or references.
- Any screenshots or videos that demonstrate your changes or show how they affect the user interface or functionality.
- Any relevant code snippets or comments that highlight important parts of your code or explain complex logic or algorithms.
- Any questions or feedback that you have for other developers or reviewers.
How to review a merge request
Reviewing a merge request is an important part of collaborating on code in GitLab. It allows you to check if the changes are correct, consistent, and compatible with the existing code base. It also gives you an opportunity to provide feedback or suggestions for improvement.
To review a merge request in GitLab, you need to have access to the project and the merge request page. Here are some steps to review a merge request in GitLab:
- Go to the project page on GitLab and click on the “Merge requests” tab.
- Find the merge request that you want to review and click on it.
- Read the title and description of the merge request and see if they are clear and informative.
- Look at the changes tab and see if there are any conflicts or errors between the source branch and the target branch.
- Review the code changes and see if they are correct, consistent, and follow the coding standards and best practices.
- Run any tests or checks that are required or recommended for the project and see if they pass or fail.
- Leave any comments or suggestions that you have for the author of the merge request. You can use the @mention feature to tag them or other developers in your comments.
- If you are satisfied with the merge request, you can approve it by clicking on the “Approve” button. If you are not satisfied, you can reject it by clicking on the “Close” button.
