How can I stop Vercel preview deployments from appearing on pull requests?

Question

I use Vercel to deploy a Next.js app and I use Vercel for GitHub for CI/CD. Vercel automatically deploys code pushed to my master branch to production, and I would like to keep this functionality. However, Vercel also creates preview deployments for each push, and when I create a pull request, this deployment shows up under 'Checks.' Is there a way to stop this from happening? I don't have an issue with Vercel creating a preview deployment for each push I make, but I would like for Vercel's deployment not to appear under the 'Checks' section of each pull request.

Answer 1

Adding the following command in the ignored build step box of /settings/git page of your project to disable running the builds for non-production environments. Effectively disabling deploy previews

[ "$VERCEL_ENV" != production ]

Answer 2

You can use the "Ignore Build Step": https://vercel.com/support/articles/how-do-i-use-the-ignored-build-step-field-on-vercel

You can tell Vercel only to build master (or main depending on your git configuration), and all other branches will be ignored.

Additionally, if you have also have a staging branch and you want builds to be run for both main and staging you can you the following command:

[[ "$VERCEL_GIT_COMMIT_REF" != "staging" && "$VERCEL_GIT_COMMIT_REF" != "main"  ]]

You can also use a add ignored build step script in the root of your project. You can read more about it here: https://vercel.com/guides/how-do-i-use-the-ignored-build-step-field-on-vercel
