How to check out a PR from an upstream repo locally?

Asked by 72b3292ace9c4098a94bc678145367

I’ve forked a repository and need to review a PR from the original upstream repo.

Normally, I’d just fetch branches manually, but I’ve heard there might be a simpler way to handle this using a tool or command. I’m particularly interested in checking out the upstream PR directly into my local environment.

Is there an efficient way to do this? If so, what’s the best approach?

I’d appreciate any guidance or instructions on how to make this process easier!

Hey there!

There’s actually a fairly easy way to check out a pull request from the upstream repo using the GitHub CLI (gh).

If you don’t already have it installed, you can grab it from here.

Once you’ve got gh set up, here’s what you need to do:

First, make sure you’ve added the upstream repo as a remote (if you haven’t already):
```
git remote add upstream https://github.com/ORIGINAL_OWNER/REPO_NAME.git
```
Next, use this command to check out the PR locally:
```
gh pr checkout PR_NUMBER --repo upstream-repo
```
Replace PR_NUMBER with the actual pull request number and upstream-repo with the correct repo name (e.g., original/repo).
After that, you’ll be on the PR branch, and you can review or work on the code just like any other branch.

If you don’t want to install gh, you could still do this the old-school way by fetching the PR branch manually, but trust me, the CLI makes it way easier!

Hope this helps! Let me know if you run into any issues! 👍
