Get rid of XMLHttpRequest() in piper.js

[guest271314]

I've bundled onyx-runtimewe.js and piper.js, created a couple standalone versions for the browser, now I'm working on running the code in node, deno, bun, txiki.js. piper.js has multiple occurrences of XMLHttpRequest(). Get rid of them.

@k9p5 What is the source code of piper.js?

[guest271314]

XMLHttpRequest() usage is not the only issue with piper.js.

There's also references to location.pathname that don't exist in a node environment.

We're going to need the source code for piper.js to proceed, compile to an actual .wasm file.

Piper.js is the javascript emscripten output

[guest271314]

Yes. What are the build steps is the question?

I think I found the origin of the build steps and your code here https://github.com/rhasspy/piper/issues/352#issuecomment-1920886683, then following links here https://github.com/ken107/piper-browser-extension/issues/2#issuecomment-2034567892, and here https://github.com/rhasspy/piper/discussions/504#discussioncomment-9482437.

It would be very helpful to publish the source of your code, including the specific Emscripten build steps you used, and where you got the steps from here, so we don't have to search through issues, discussions, blame.

I'm getting all sorts of errors trying to reproduce the steps, for the purpose of compiling for 'shell' environment, so we don't get window and location.pathname references in the output.

I think I've manually gotten rid of XMLHttpRequest() in piper.js. Now the issue is onyxruntime-web and onyxruntime-node

bun install onxyruntime-node 
bun build node_modules/onnxruntime-node/dist/index.js --outfile=ort-bundle.js

error: Uncaught (in promise) Error: no available backend found. ERR: [wasm] NotSupported: Classic workers are not supported., [cpu] Error: previous call to 'initWasm()' failed.

[guest271314]

This is going to take some work. I'm in to onyxruntime-web and onyxruntime-node now.

node --experimental-default-type=module index.js

Error: no available backend found. ERR: [wasm] TypeError: Worker is not a constructor, [cpu] Error: previous call to 'initWasm()' failed.
