If you just want static data, using jsroot or jsfive might be a better option.

I think you missed the main part: the dataset is not in memory. This is not SQLite-in-the-browser but using a virtual file system over HTTP. Neither of those alternatives do anything similar.

Same with those! They'll just grab the chunks they need (also with range requests) to do what you want from binary ROOT or (presumably, I haven't actually used jsfive) HDF5 files.
