Encoding NEXT_DATA json

[PiotrSzlagura]

Describe the feature you'd like to request

Is it possible to introduce (or implement it for given project, I would be 100% satisfied with a guide how to implement it myself) a function, that will encode NEXT_DATA into base64 or something like that and decode it when needed?

The problem which this function can fix, is Google crawling bits of NEXT_DATA and trying to open links which are not valid (in my case, I use parts of urls in next data with which I build urls in code, Google then tries to enter that url part and reports a lot of 404's).

Describe the solution you'd like

1. During getInitialProps, encode data in BASE64 (or other format)
2. When hydrating on client side, decode this data and use it as it would be used otherwise

Describe alternatives you've considered

I tried adding something like rel="nofollow" and looked into workarounds like <!--googleoff: all--> (which doesnt work).

One other idea - would it be possible to create a special variant of page (only for robots) which would have no NEXT_DATA script at all? This would also solve my primary issue

[PiotrSzlagura]

There is one more thing which troubles me with current state of NEXT_DATA - on each page this JSON contains data about current page, this string starts with / and is crawled by Google (but this is not a real url, it's something like [locale]/companies. This negatively affects SEO

did you find any solution?

[PiotrSzlagura]

We might say that I did, but I wouldn't call that a solution.

I finally decided to make sure that my NEXT_DATA doesn't contain any strings starting with /...

As for the problem with url patterns being picked up by Google - I still don't have any solution for it unfortunately
