ZetaJS wraps ZetaOffice, a WASM version of LibreOffice - and makes accessing the entire gamut of the LibreOffice programmability interfaces from JavaScript convenient, idiomatic & extremely fast.
If you always wanted an entire client-side office suite in the browser, that you could fully automate with JS & seamlessly embed in your web apps - and on top of that, be able to self-host it & keep all data on the client, since there's literally no server involved (except for some static wasm & JS blobs) - then this might be for you.
