Can I fix buildId when output export?

[zao95]

Summary

I'm using the next 14.2.13 version, and it's an SSG build environment through output: 'export' setting.

There is a limit to the number of files when deploy on my company system,
I want to fix buildId by modifying the next.config.js file as below.

generateBuildId: async () => {
    return "fixedBuildId"
  },

In this process, I am considering settings because I am worried about cache processing.

I plan to set the Cache-Control: no-cache, no-store header to respond to the two files in case /out/static/fixedBuildId/_buildManifest.js and /out/static/fixedBuildId/_ssgManifest.js change during the build path.

Other than this, are there any additional side effects from fixing buildId?

Additionally, it seems that the list of chunks for pages written in the past _buildManifest.js is written at {path}.txt in each path, but doesn't the txt file also need a Cache-Control header?

I remember someone asked this way before, a few years back perhaps, and they reported back that it had caused some issues. Let me find it for you.

There are more than 800 pages in the project, but the maximum file changes when deployed on the company system are limited to 200.
The buildId changes even when using githead,
I understand that each page has a change based on buildId, so I don't think it will fit with the system.

I'll check the attached thread.
Thank you for your answer.

Aha, I think you want to fix the webpack chunk ids rather...

Here ya go: #65856 (reply in thread)

It looks like, potentially, a bug is at play here as well... Read the whole thread I'm linking, not just the workaround.

The thread you posted confirms that when you build generateBuildId in two or more separate instances, the results may be different, is it correct that I understand?
Fortunately, in my environment, the build results are copied, so I don't think it will be applied to the error case above.

During testing, the hash values used for page and chunk file names change only when the code changes, in the case of the pages router,
However, when you configure it as an app router, all files change every time you build it
Oh, my..
