Why are My Next.js API Endpoints Not Updating After Deployment?

Next.js API Endpoints Not Updating After Deployment

Problem: Data fetched from a database via an API endpoint is remaining static after project deployment.

Analysis: The issue likely stems from caching. In Next.js, API routes and Server Components have caching enabled by default for performance optimization. This caching can interfere with data updates.

Solution:

To prevent caching and ensure dynamic data updates, adjust the caching behavior as follows:

• Using fetch():

  • Add the revalidate option to the fetch() request to specify a revalidation interval in seconds:

    fetch('https://...', { next: { revalidate: 10 } });

  • Alternatively, set the cache option to no-store to disable caching:

    fetch('https://...', { cache: 'no-store' });

• Using Route Segment Config:

  • In the layout.js, page.js, or route.js file, add the following code to disable caching for the specific route segment:

    import prisma from './lib/prisma';
    
    export const dynamic = 'force-dynamic';
    
    async function getPosts() {
      const posts = await prisma.post.findMany();
      return posts;
    }
    
    export default async function Page() {
      const posts = await getPosts();
      // ...
    }

By following these steps, you can disable caching for API endpoints and ensure that data updates are reflected promptly after deployment.
