Dashboard file-server from sd-card (esp32-s3)

[pirzimm]

Hello everyone,

I would like to build a file server with mongoose so that it is possible to download log files from the external sd card of the esp32-s3 via the dashboard.
I am currently running a slightly modified version of the dashboard example on mg version 7.12.
Is there an example that does something similar?
I tried to use the mg_http_serve_dir function, but I think this is not compatible with the external SD card.
(I'm not that experienced with frontend implementation and http communication protocols, which is why I'm stuck)

Thanks for any help

Please follow the guidelines in the documentation, examples and tutorials available.

Mongoose is not compatible nor not-compatible with your external SD or whatever, it reads a file system. The very first lines in app_main() in the example mount a filesystem. Make sure the one you want is mounted.
https://github.com/cesanta/mongoose/tree/master/examples/esp32/device-dashboard/main/main.c#L10-L18
Then, to serve files from that filesystem, read the docs and add the proper filesystem option to mg_http_serve_dir():
