Web support for mimir is currently not possible due to the lack of a publicly-available libc implementation for WASM made with JS & browser APIs. This concept of a browser-based libc sounds weird, because it is, but it isn't actually too bad; keep reading to see why.

A libc implementation via web APIs is theoretically possible (and has been done in some capacity!), as seen with https://webvm.io. WebVM was created with CheerpX and is written about in more detail here.

Considering an entire VM runs natively in the browser already using an in-progress libc implementation, and that VM itself isn't terribly slow, I see promise for the possibility of web support for this library (and many others) in the not-so distant future. (Again, this all relies on an open-source libc implementation that can be used by Rust.)

libcs for the web are already available to differing degrees of completeness. Now it is just a matter of being able to use them.
