Feature request "Write JSON/GEOJSON file into a memory buffer"

[apalacio9502]

Hi @coolbutuseless,

I think it would be interesting to have an implementation of write_json_file and write_geojson_file in a memory buffer, which returns the raw vector of the JSON/GEOJSON file to avoid writing to disk in cases where the goal is to get the raw data from the file.

So I can understand your issue better, could you give a mocked worked example of what you want to do?

Hi @coolbutuseless ,

Apologies for the delayed response. In general, this functionality would be interesting for data transmission processes in raw format. I believe it would have significant potential in libraries like bigrquery, plumber, etc.

As an example, currently, when you want to obtain the raw data from a JSON using yyjsonr, you have to first write the JSON file and then read the raw data. However, this is inefficient because it involves using disk storage.

The idea would be to introduce a parameter similar to what was implemented in nanoparquet r-lib/nanoparquet#31, or a new function, allowing direct access to raw data without the need for intermediate disk storage.
