Introduction

Pull Request and Merge Request are additional operations to the Git tool that GitHub and GitLab provide us, and allow us to work in a more organized way, with the supervision of another person before integrating our code in a repository.

Prerequisites

The prerequisites to do these operations are:

• Have forked the repository we want to collaborate with (main repository).
• Have done some changes to files.

Operations

At this point, we can make a request to integrate these changes into the main repository.

In order to do this, the following operations will be necessary:

• Make a Pull Request (GitHub) or a Merge Request (GitLab).
• Ask someone else to review our code.
• Ask this other person push this change into the master repository.

Once this process is finished, we will see our changes (our commit) in the main repository.

Pull Request (on GitHub)

In the second account, load the project page:

Fork:

Change some files.

Click on Pull Request / New pull request:

Click on Create pull request:

In the main account, click on Pull Request (1):

Merge Request (en GitLab)

In the second account, load the project page:

Fork:

Change some files:

In the left column, click on Merge Request / New Merge Request:

Click on Compare branches and continue:

Review Merge request:

In the main account, click on Merge requests (1):

Click on the name of the merge request / Merge:

Conclusion

We have seen that these extra operations help us to add an extra step when it comes to integrating our changes with the important detail of having someone else review and comment on those changes with us.
