Root Cause

I can pass this data through search params, and that works; however, I do not want to do this because:

  1. I don't want the page to be easily bookmarkable
  2. For the operation I'm working on, it is not traditional to expose the values user-side, it makes for ugly URLs

What is the documentation issue?

The docs say to use route.js to handle POST data, but sometimes, you need a POST page to show html content, and not just redirect. However, there doesn't seem to be a description of how to handle POST data in page.js, at least in the context of an app router.

Is there any context that might help us understand?

I need to inject data into a page's components.

I can pass this data through search params, and that works; however, I do not want to do this because:

  2. For the operation I'm working on, it is not traditional to expose the values user-side, it makes for ugly URLs

What doesn't work for me:

  1. Using a route.js page, because while that allows me to handle POST data, it doesn't solve the problem; even if I were to redirect to the page, I still need to somehow pass the data. Storing it in a cookie before moving to the next page is doable, but that sounds like a very roundabout way.
  2. I need the same URL to handle both POST and GET (The reasons why are not relevant to this issue, please do not discuss that).

I suppose I could use a route.ts and send back a string in the get() function, but that means I can't use components, or any of the regular workflows I normally use.

extent analysis

TL;DR

Use a temporary storage mechanism, such as session storage or a server-side cache, to pass data between pages without exposing it in the URL.

Guidance

  • Consider using a server-side solution to handle POST data and store it temporarily, allowing you to redirect to a page without passing sensitive data in the URL.
  • Look into using a library or framework feature that supports server-side rendering and data passing, such as Next.js's getServerSideProps method.
  • Evaluate the trade-offs of using a cookie or other client-side storage mechanism, despite the initial reluctance, as it may be a viable workaround.
  • Review the prior literature and related issues, such as the mentioned Next.js issue, to see if any solutions or workarounds were discussed.

Example

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

Notes

The solution may depend on the specific requirements and constraints of the application, such as the need to handle both POST and GET requests on the same URL.

Recommendation

Apply a workaround, such as using a temporary storage mechanism or server-side solution, as a direct solution is not clearly implied in the issue. This approach allows for handling POST data without exposing it in the URL, while also considering the need to handle both POST and GET requests on the same URL.
