5 Common Vercel Mistakes New Developers Make and How to Avoid Them

As a new developer diving into Vercel, it's easy to overlook some fundamental practices that can lead to frustrating deployment issues or performance bottlenecks. I remember when we first started using Vercel for our projects; we made several blunders that cost us time and headaches. In this guide, I’ll share five common mistakes we see new developers make with Vercel, how to avoid them, and practical solutions to ensure smoother deployments.

1. Ignoring Environment Variables

What’s the Mistake?

Many new developers forget to configure environment variables properly, leading to issues in production that don't appear in development.

How to Avoid It

Always set up your environment variables in Vercel's dashboard. Remember to test them locally using .env files to ensure they match what you’ve set in Vercel.

Our Take

We once deployed a feature that relied on an API key but forgot to set it in production. The result? A broken feature and a lot of scrambling. Now, we double-check all environment variables before deployment.

2. Not Leveraging Vercel Functions

What’s the Mistake?

New developers often overlook Vercel Functions, relying solely on client-side code for tasks that can be handled server-side.

How to Avoid It

Utilize Vercel Functions for things like form submissions or API calls. This not only improves performance but also keeps sensitive logic off the client.

Our Take

We initially tried to handle everything on the client side, which led to slow load times. By moving critical logic to Vercel Functions, we saw a significant performance boost.

3. Overlooking Caching Strategies

What’s the Mistake?

Failing to implement caching effectively can lead to unnecessary server requests, slowing down your application.

How to Avoid It

Use Vercel's built-in caching capabilities, such as Cache-Control headers. This can drastically improve load times for static assets and API responses.

Our Take

We once had a project where we served static assets without caching. The increase in load times was evident. Implementing proper caching reduced our load times by 40%.

4. Skipping Performance Monitoring

What’s the Mistake?

New developers often neglect to monitor their application's performance post-deployment, missing critical insights into user experience.

How to Avoid It

Leverage tools like Vercel Analytics or third-party services like Google Analytics to track performance metrics. Regularly review these metrics to spot issues early.

Our Take

We didn’t monitor performance for one of our launches and missed a critical slowdown that affected user engagement. Now, we check our metrics weekly.

5. Misunderstanding Build Settings

What’s the Mistake?

New developers might misconfigure their build settings, leading to deployment failures or unexpected behavior in production.

How to Avoid It

Take the time to understand Vercel's build settings and configure them according to your project needs. Ensure your frameworks are correctly specified.

Our Take

We once had a misconfigured build setting that caused our Next.js app to fail to build. After some head-scratching, we realized the framework wasn’t set correctly. Now, we meticulously check these settings before deployment.

Conclusion: Start Here

If you're new to Vercel, start by prioritizing environment variables and leveraging Vercel Functions. Implement caching strategies and monitor performance closely. Lastly, ensure your build settings are correctly configured. These steps will save you time and headaches as you build and deploy your projects.

What We Actually Use

• Vercel Functions for server-side logic
• Vercel Analytics for performance tracking
• Proper caching strategies to enhance load times

By avoiding these common mistakes, you'll set yourself up for success with Vercel. Happy building!
