Extension Set Up

1. Create a Vercel Project
2. Create a Vercel Personal Access Token with permissions to deploy the project created on step 1 (see the Vercel PAT Set Up guide for more information)
3. If you're planning on using the Pull Request Commenting Task, create an Azure DevOps Personal Access Token with permissions to Read/Write Pull Request threads (see the Azure PAT set up guide for more information)
4. Store the tokens as secret variables in your preferred methodology. Azure recommends using the UI, Variables Groups, or Azure Key Vault. Whichever methodology you use, make sure it is accessible from Azure Pipelines.
5. Navigate to the Vercel Deployment Extension Visual Studio Marketplace page and add the extension to your organization.

   Note: This step will not work until the extension is shared with the user or we make the extension public.

6. With the extension added, you are now ready to use the tasks in your Azure Pipeline. The tasks are referable using vercel-deployment-task and vercel-azdo-pr-comment-task.

   Note: Within a pipeline definition, the tasks will be used like - task: vercel-deployment-task@3. The @3 represents the Major version of the task that the pipeline should use. Make sure to indicate the latest major version of the task when creating your pipeline.

Explore the following pipeline guides for further set up instructions:

Basic Pipeline Set Up

This short guide will demonstrate how the extension can be used to automatically deploy the main branch to production. Make sure the steps in Extension Set Up have been completed.

1. Start by creating a new pipeline file in your repo called basic-pipeline.yml. Either use the in-browser editor, or in your local file editor.

2. Add a trigger:, pool:, and steps: declarations:

   trigger:
     - main
   
   pool:
     vmImage: ubuntu-latest
   
   steps:
   # - task: ...

   The trigger: declaration states that this pipeline should run for all commits to the main branch.

3. Now add the extension's task vercel-deployment-task:

   steps:
     - task: vercel-deployment-task@3
       name: Deploy
       inputs:
         vercelProjectId: "<project-id>"
         vercelTeamId: "<team-id>"
         vercelToken: "<vercel-token>" # '$(VERCEL_TOKEN)'
         production: true

   • The vercelToken should reference the secret variable defined in Extension Set Up.

4. Commit, and push the pipeline to the repository.

5. Navigate to Azure Pipelines and run the task for the first time if it doesn't run automatically.

6. Make a change to your project and commit to the main branch, a new deployment pipeline run should automatically kick off in Azure Pipelines, and the Vercel Project should automatically update.

Full Featured Pipeline Set Up

This guide will demonstrate how to improve the Basic Pipeline Set Up pipeline in order to deploy from main to production and deploy from pull requests to preview.

1. Starting with the pipeline file created in Basic Pipeline Set Up, duplicate, rename, or open it in your editor of choice.
2. Add a variable above the steps block

   variables:
     isMain: $[eq(variables['Build.SourceBranch'], 'refs/heads/main')]

3. Update the production: true input to be production: $(isMain)
4. Below inputs:, add a condition:

   inputs:
     # ...
   condition: or(eq(variables.isMain, true), eq(variables['Build.Reason'], 'PullRequest'))

5. Then add a new task step immediately after the vercel-deployment-task step, adding the PR commenting feature:

   - task: vercel-azdo-pr-comment-task@3
     inputs:
       azureToken: $(AZURE_PAT)
       deploymentTaskMessage: $(Deploy.deploymentTaskMessage)

   • The vercel-deployment-task sets an output variable called deploymentTaskMessage. The reference $(Deploy.deploymentTaskMessage) comes from the name: Deploy on the vercel-deployment-task step.
6. Push these changes to the repository, and set a Build Policy for the main branch.
7. Now create a new branch, push a commit, and open a PR against main. A new pipeline execution should trigger and it should create a preview deployment on Vercel as well as comment back on the PR with the preview URL.
