Continuous Deployment with Vercel: Automate your deployment pipeline

03 October 2023 by Daria Andrieieva

In the fast-paced world of web development, efficiency and automation are paramount. Continuous Deployment (CD) is automating the deployment of code changes to production, ensuring that your web applications are always up-to-date without manual intervention. In this guide, we'll delve into the world of CD, focusing on deploying to Vercel, a powerful platform for hosting and deploying web applications. 

Join Kapsys in this article to understand how to automate your deployment pipeline using Vercel.

What is Continuous Deployment?

Continuous Deployment is an extension of Continuous Integration (CI), a development practice where code changes are frequently integrated into a shared repository. CI ensures that each code change is automatically tested, which helps detect and fix issues early in development. Continuous Deployment takes this further by automatically deploying these code changes to a production environment after passing all tests.

The benefits of continuous deployment are numerous:

  • Reduced Manual Intervention: With CD, there's no need for manual deployment, reducing the risk of human error.

  • Faster Time to Market: Code changes are deployed as soon as they're ready, allowing you to deliver new features and fixes faster.

  • Consistency: CD ensures that all environments are consistent, reducing the "it works on my machine" problem.

  • Immediate Feedback: Any arising issues are caught and addressed immediately, promoting better code quality.

Deploying to Vercel: Why Vercel?

Vercel is a cloud platform specializing in web applications and offering various features tailored to modern web development. Here are some compelling reasons to choose Vercel for your continuous deployment needs:

How to Deploy to Vercel: A Step-by-Step Guide

Deploying with Vercel is very easy, and in this section of the blog post, we'll introduce you to a step-by-step guide, that will make your deployment process so much simpler.

Step 1. Create a Vercel account

If you still need to, the first step is to create a Vercel account. Sign up using your GitHubGitLabBitbucket account, or email address.

Step 2. Install the Vercel CLI

To interact with Vercel from your local development environment, you must install the Vercel Command Line Interface (CLI). You can do this using npm (Node Package Manager) by running the following command:

npm install -g vercel

Step 3. Connect your project

Once you have the CLI installed, navigate to your project directory and run the following command to connect your project to Vercel: vertical login.

Follow the prompts to authenticate and link your project to your Vercel account.

Step 4. Configure your deployment settings

Vercel allows you to configure your deployment settings through a vercel.json or now.json file in your project directory. You can specify settings like the build and output directories, environment variables, etc. Here's a basic example:


  "name": "my-project",

  "builds": [


      "src": "package.json",

      "use": "@vercel/node"



  "routes": [{ "src": "/(.*)", "dest": "/" }],

  "env": {

    "API_KEY": "@my-api-key"



Step 5. Set up GitHub integration

To further automate the continuous deployment process, integrate your GitHub repository with Vercel. This allows Vercel to deploy changes whenever you push to your GitHub repository automatically.

  • In your Vercel dashboard, click on "Import Project."

  • Select your GitHub repository and configure the settings.

Step 6. Define deployment triggers

You can define deployment triggers based on branches or pull requests with GitHub integration. For example, you can set up Vercel to deploy changes automatically when you push to the main branch.

Step 7. Deploy your application

Now that everything is set up deploying your application is as simple as pushing your code changes to GitHub. Vercel will automatically detect the changes, build your application, and deploy it to your specified environment.

Monitoring and Troubleshooting

Continuous Deployment with Vercel is a powerful tool, but monitoring your deployments and troubleshooting any issues that may arise is essential. Vercel provides extensive logging and monitoring capabilities to help you diagnose problems quickly.

In your Vercel dashboard, you can view deployment logs, monitor performance metrics, and set up alerts for critical issues.

Monitoring best practices

Here are some of the most critical monitoring tips for continuous deployment:

  • Set Up Alerts: Use Vercel's alerting system to notify you of critical issues, such as failed deployments or performance degradation. Define thresholds and conditions that trigger alerts so that you can take immediate action.

  • Performance Metrics: Monitor key performance metrics like response time, server load, and resource utilization. Vercel provides built-in performance metrics, but you can integrate third-party monitoring tools like New Relic or Datadog for more comprehensive insights.

  • Log Aggregation: Collect and centralize your application logs. Vercel provides records for each deployment, making it easier to pinpoint issues. Consider using tools like Elasticsearch and KibanaLoggly, or Papertrail for log aggregation and analysis.

  • User Experience Monitoring: Implement accurate user monitoring (RUM) to gain insights into how your application performs from the user's perspective. Tools like Google AnalyticsHotjar, or New Relic Browser can help you track user interactions and identify performance bottlenecks.

  • A/B Testing: Implement A/B testing to compare different versions of your application and gather user feedback. Services like VWO and Optimizely can help you track the impact of changes on user engagement and conversion rates.

Troubleshooting tips

Now, as we move forward, let's look into some of the best troubleshooting tips for continuous deployment:

  • Deployment logs. If you encounter problems, start by reviewing the deployment logs provided by Vercel. These logs often contain valuable information about what went wrong during deployment.

  • Bug tracking. Implement bug-tracking tools like Sentry or Rollbar to track and report application bugs. These tools can help you identify and prioritize problems based on their impact.

  • Rollback Strategy. Develop a rollback strategy. If a critical issue occurs during deployment that cannot be resolved quickly, it is essential to be able to roll back to a previous stable version of your application.

  • Automated testing. Invest in comprehensive automated testing, including unit, integration, and end-to-end tests. Computerized tests can identify many problems before they reach production.

  • View dependencies. Regularly check and update your application's dependencies, including libraries, frameworks, and packages. Outdated dependencies can create security vulnerabilities and compatibility issues.

  • Cooperation. Promote collaboration between development, operations, and quality assurance teams. Effective communication can help you identify and solve problems more effectively.

While continuous deployment with Vercel enhances development efficiency, essential monitoring practices and troubleshooting are vital. Vercel offers valuable tools to ensure your web applications run smoothly, including deployment logs and performance metrics.
