You can use Vercel CLI to create Preview Deployments and can also use the Vercel CLI to alias a URL to that deployment. Each preview deployment has a unique URL. The latest Preview Deployment is automatically aliased to a URL, ensuring you'll have a stable URL pointing to the last Preview Deployment.
This covers adding another URL to the Deployment using the alias command. In this example we use the Vercel CLI to do a deployment using the vercel deploy command. A successful deployment writes the deployed URL to the Standard Output so you can use it in later commands.
As an example:
url="$(vercel deploy)"vercel alias set "$url" your-alias.appIn this article we cover how to deploy using GitHub Actions. We can expand that example and alter the last couple of lines to do that auto-aliasing.
To set this Action up, please refer back to the original article. Then change the last lines as below:
name: Vercel Preview Deploymentenv: VERCEL_ORG_ID: ${{ secrets.VERCEL_ORG_ID }} VERCEL_PROJECT_ID: ${{ secrets.VERCEL_PROJECT_ID }}on: push: branches-ignore: - mainjobs: Deploy-Preview: runs-on: ubuntu-latest steps: - uses: actions/checkout@v2 - name: Install Vercel CLI run: npm install --global vercel@latest - name: Pull Vercel Environment Information run: vercel pull --yes --environment=preview --token=${{ secrets.VERCEL_TOKEN }} - name: Build Project Artifacts run: vercel build --token=${{ secrets.VERCEL_TOKEN }} - name: Deploy Project Artifacts to Vercel run: | url="$(vercel deploy --prebuilt --token=${{ secrets.VERCEL_TOKEN }})" vercel alias --token=${{ secrets.VERCEL_TOKEN }} set "$url" your-alias.app
