5 Common Mistakes When Using Vercel That Could Delay Your Deployment

Deploying with Vercel can feel like a breeze, but if you’re not careful, you can easily hit snags that delay your launch. As indie hackers and solo founders, we know that every hour counts, and deployment issues can derail your timeline. Here are five common mistakes that can slow you down, along with how to avoid them.

1. Ignoring Environment Variables

What Happens:

One of the most frequent mistakes is neglecting to set up your environment variables correctly. If your app relies on API keys or other sensitive information, forgetting to configure these can lead to runtime errors.

Solution:

Ensure you use Vercel's environment variable management feature. Set up your variables in the dashboard under "Settings" > "Environment Variables."

Our Take:

We’ve had to troubleshoot for hours because we missed a single variable. Double-check your settings before deploying.

2. Not Optimizing for Serverless Functions

What Happens:

Vercel excels at serverless functions, but if you don’t optimize your code, it can lead to slow responses and timeouts, especially under load.

Solution:

Keep your functions lightweight and efficient. Use caching where possible and avoid heavy computation in your serverless functions.

Limitation:

Remember, serverless isn't suitable for all workloads. If your function requires long processing times, consider alternatives like AWS Lambda.

3. Overlooking Build Caching

What Happens:

When you deploy, Vercel caches your builds. If you don’t take advantage of this feature, you might end up rebuilding everything from scratch, which is time-consuming.

Solution:

Use the vercel.json configuration file to set caching rules that suit your project. This can significantly speed up subsequent deployments.

Our Experience:

We often forget to configure this, resulting in longer build times. It’s a small step that can save you considerable time.

4. Skipping the Preview Deployments

What Happens:

Some developers skip preview deployments, thinking they can just deploy directly to production. This can lead to unexpected bugs in your live environment.

Solution:

Always use Vercel's preview deployment feature to test changes in a safe environment before going live.

Best Practice:

We use preview deployments for every feature branch. It saves us from embarrassing production issues.

5. Misconfiguring the Domains

What Happens:

Incorrect domain settings can lead to downtime or misrouting of traffic. This is especially problematic for those running multiple environments (dev, staging, production).

Solution:

Double-check your domain settings in the Vercel dashboard. Ensure that you’ve set up your custom domains correctly and that they point to the right environments.

Limitation:

Make sure you understand DNS settings, as this can be a common pain point for many developers.

Conclusion: Start Here to Avoid Delays

To expedite your deployment process with Vercel, focus on these five areas. By taking a proactive approach to environment variables, optimizing serverless functions, leveraging build caching, utilizing preview deployments, and configuring domains correctly, you can minimize delays and get your product into users' hands faster.

If you're just starting out or looking to refine your deployment process, make sure to implement these tips. It’s all about working smarter, not harder.
