Disabling preview deployments in Vercel

vercel

If you don't want Vercel to do preview deployments for other branches of your repository you can disable preview deployments by going to your project's settings > git > Ignored Build Step and add the following command:

if ["$VERCEL_ENV" == "production"]; then exit 1; else exit 0; fi

This is probably the easiest way. Another way would be to add a vercel.json to all branches and set "deploymentEnabled" to false for any branches that should not trigger deployment, like below:

{
  "git": {
    "deploymentEnabled": {
      "gh-pages": false
    }
  }
}
