wasmThreadSupported returns false in node about stockfish.wasm

[niklasf]

Correct, the current feature detection is only intended for browser, but if you can figure out a way to feature test for node, I am happy to add it.

Some of these things can be pretty application specific (growable memory required? fallback to single-threaded wasm? fallback to js? run a pool of fallbacks? ...), so I've hesitated to add more than the example.

Related question, in the readme it says that the only browser that supports this package is firefox. But when I go to https://lichess.org/analysis, even in safari it says it is using "Stockfish 10+ WASM". Is that this package (or the .wasm from stockfish.js)?

[niklasf]

Multi-threaded WASM is supported by Firefox, Chromium (and thus Chrome and Edge).

"Stockfish 10+ WASM" is single threaded WASM, though. Multi-threaded WebAssembly on Lichess would show as "Stockfish 12+ WASMX" (for eXperimental).

Ah. Yes, my Firefox needed to be updated. I get WASMX when I check on Chrome and Firefox now.

I'm boing to close this issue d/t your first response

PS. What I've been doing on Node is pretty Naive. i just check that the version is 14 and that the experimental flags are included in the process variable.
