5 Mistakes Every New Vercel User Makes and How to Avoid Them

When you first dive into Vercel, it can feel like a breath of fresh air—fast deployments, seamless integrations, and a snazzy interface. However, I've seen many new users stumble in the early days. Having gone through the learning curve ourselves, we’ve identified five common mistakes that can trip you up. Let’s break down these pitfalls and, more importantly, how to avoid them.

1. Ignoring Build Logs

The Mistake

New users often overlook the build logs when something goes wrong. Instead of diving into the logs, they might spend hours trying to troubleshoot based on vague error messages or simply assume their code is fine.

The Solution

Make it a habit to check the build logs during every deployment. Vercel provides detailed logs that can point you to the exact issue. If your deployment fails, look for red flags in the logs. They often contain actionable insights, such as missing environment variables or failed dependencies.

Expected Output: Clear error messages will guide you directly to the problem.

2. Not Setting Environment Variables Properly

The Mistake

Another common pitfall is misconfiguring environment variables. Many beginners either forget to set them up or mislabel them, leading to unexpected behavior in their applications.

The Solution

Double-check your environment variable settings in the Vercel dashboard. Use the right naming conventions and ensure they match what your application expects.

Tip: Use local .env files during development and replicate the same variable names in Vercel.

Expected Output: Your application should run smoothly with the correct configurations.

3. Skipping Custom Domains Setup

The Mistake

Many new users deploy their applications but forget to set up custom domains. This can leave your app on the default Vercel URL, which isn’t ideal for branding or SEO.

The Solution

Take the time to set up a custom domain right after your first deployment. Vercel makes this process straightforward. Just go to the "Domains" section in your project settings and follow the prompts.

Expected Output: Your application will be accessible via your custom domain, enhancing professionalism.

4. Overlooking Caching Strategies

The Mistake

New users often neglect to configure caching strategies, resulting in longer load times and inefficient resource use.

The Solution

Understand how caching works in Vercel. Use the Cache-Control headers to manage how your assets are cached. You can adjust caching rules based on your app's needs, whether it’s for static assets or dynamic routes.

Expected Output: Faster load times and a better user experience.

5. Not Using Preview Deployments

The Mistake

Many beginners don’t take advantage of Vercel’s Preview Deployments feature. This leads to deploying untested changes directly to production.

The Solution

Always use Preview Deployments for new features or changes. Vercel automatically creates a unique URL for each pull request, allowing you to test your changes in a live environment without affecting your main application.

Expected Output: You can identify issues before they go live, reducing the risk of breaking changes.

Conclusion: Start Here

To avoid these common pitfalls when using Vercel, make sure to check your build logs, set environment variables correctly, configure custom domains, manage caching effectively, and utilize Preview Deployments. Taking these steps will save you time and headaches as you build and deploy your applications.

If you're just starting with Vercel, I recommend going through their official documentation and setting up a simple project to familiarize yourself with the platform.

What We Actually Use

In our experience, we rely heavily on Vercel for hosting our frontend applications due to its speed and simplicity. We use environment variables for our API keys, and we always set up custom domains to maintain a professional appearance. We also make it a point to utilize Preview Deployments for testing before pushing any changes live.
