Javier,
no that's currently not possible, although it would certainly be
possible to plug the SQLite I/O layer onto the PROJ network layer. That
said, that would use curl underneath, and I don't think curl is really
an option in a WASM context. I'm not totally sure of the interest of
not having proj.db embedded in the wasm itself, if it needs to be
remotely fetched then. And PROJ's use of the database, when computing
coordinate operations to transform from a CRS to another one, often
involves reading a significant amount of the DB, so that could involve
lots of small network requests, which might be less efficient than full
ingestion of the DB.

Hi
I am working with Will on a wasm version of PROJ, trying to support
also remote grids (using emscripten_fetch).
Do you know if there a way to specify the location of proj.db as a
remote URL? in that case, it would not be embedded in the wasm file
itself. (I am not sure if it does make sense).
Cheers,
Javier.
