Top Mistakes When Deploying Next.js Apps

Deploying Next.js applications can be a rewarding experience, but it’s not without its pitfalls. Whether you’re a developer or a DevOps engineer, understanding the common mistakes made during deployment can save you time, resources, and headaches. In this blog post, we’ll explore the top mistakes to avoid when deploying Next.js apps, provide actionable solutions, and introduce you to tools like Kuberns that can streamline your deployment process.

1. Ignoring Environment Variables

Mistake:

Many developers hardcode sensitive information or configuration values directly into their codebase. This not only poses security risks but also makes it difficult to manage different environments (development, staging, production).

Solution:

Use .env files and Next.js’s built-in support for environment variables. Prefix variables with NEXT_PUBLIC_ if they need to be exposed to the browser. Always keep sensitive keys out of the client-side code and use environment-specific files like .env.production and .env.local.

2. Misconfiguring Static and Dynamic Routes

Mistake:

Next.js offers both static generation (SSG) and server-side rendering (SSR). Misunderstanding when to use each can lead to performance issues or broken routes.

Solution:

  • Use getStaticProps and getStaticPaths for static content.
  • Use getServerSideProps for dynamic, frequently changing data.
  • Double-check your next.config.js for correct rewrites and redirects.

3. Overlooking Image Optimization

Mistake:

Uploading large, unoptimized images can slow down your app and increase bandwidth costs.

Solution:

Leverage Next.js’s built-in component, which automatically optimizes images. Configure remote image domains in next.config.js and use appropriate image sizes for different devices.

4. Neglecting Serverless Deployment Nuances

Mistake:

Deploying to serverless platforms (like Vercel, AWS Lambda, or Kuberns) without understanding cold starts, function limits, or file system restrictions can cause unexpected behavior.

Solution:

  • Familiarize yourself with the limitations of your deployment platform.
  • Avoid relying on local file system writes at runtime.
  • Use environment variables and cloud storage for persistent data.

5. Improper Build and Caching Strategies

Mistake:

Not optimizing your build process or caching strategy can lead to slow deployments and poor user experience.

Solution:

  • Use Next.js’s incremental static regeneration (ISR) for updating static content.
  • Configure proper cache headers for static assets.
  • Clean up unused dependencies and optimize your bundle size.

6. Not Leveraging Deployment Platforms

Mistake:

Manually managing deployments can be error-prone and time-consuming.

Solution:

Use modern deployment platforms like Kuberns, Vercel, or Netlify. These platforms offer automated builds, zero-downtime deployments, and easy rollbacks. Kuberns provides a developer-friendly interface for deploying and managing backend services on Kubernetes, with front-end deployment support (like full Next.js apps) coming soon.

7. Failing to Monitor and Log

Mistake:

Deploying without proper monitoring and logging can make it difficult to diagnose issues in production.

Solution:

  • Integrate logging solutions like LogRocket, Sentry, or Datadog.
  • Set up health checks and alerts for your deployments.
  • Use platform-native monitoring tools (Kuberns offers built-in monitoring dashboards for your apps).
