nextjs - 💡(How to fix) Fix [Cache Components] Component being displayed in another route that doesn't use it [10 comments, 5 participants]

TL;DR

• The issue can likely be resolved by adjusting the cacheComponents configuration in next.config.ts to properly handle the dropdown component.

Guidance

• Investigate the cacheComponents configuration in next.config.ts to ensure it is correctly set up to exclude the dropdown component from caching on pages where it is not included.
• Verify that the dropdown component is properly unmounted when navigating away from pages that include it.
• Check the Next.js documentation for any known issues or updates related to cacheComponents in version 16.0.0.
• Consider temporarily disabling cacheComponents to confirm whether it is the root cause of the issue.

Example

• No code example is provided due to the lack of specific code details in the issue.

Notes

• The issue seems to be closely related to the cacheComponents feature in Next.js 16.0.0, and resolving it may require a deeper understanding of how this feature interacts with the dropdown component.
• The fact that the issue was introduced in a specific canary version and is resolved by disabling cacheComponents suggests that the problem is likely related to how Next.js handles component caching.

Recommendation

• Apply workaround: Temporarily disable cacheComponents in next.config.ts to prevent the dropdown menu from being incorrectly cached and displayed on pages where it is not included, until a more permanent solution or fix from Next.js is available.
