compile to wasm

[lhk]

Feature description

I would like to embed machine translation in my webapp. There is tensorflow.js but so far I've been unable to find suitable pretrained translation models.

Opus-MT hosts a large repository of pretrained models for many language pairs. It uses marian for the neural machine translation.

The pre- and postprocessing is cheap. I would be able to host the tokenizer on a server. But marian-decoder is too costly to host myself.
It would be great if it was possible to compile the code to webassembly and run it client-side.

I have written small projects in C/C++ and in principle would be happy to dig deeper. But guidance from someone with more experience would be really helpful.

Is this feasible at all?

Your request is well timed since Mozilla is working on this through my project https://browser.mt/. Let's take this over to https://github.com/browsermt/marian-dev and talk with @mlopatka and @abhi-agg.

Closing only because we'll discuss it in browsermt/marian-dev#5
