Build for the web gives "spawn emcc ENOENT" #1

Thank you for pointing this out @Catalan-1ap. The build-wasm script requires the Emscripten Compiler Frontend (emcc) to produce the WebAssembly output. For CI and for releases, we currently use a slightly older version of the Emscripten SDK:

https://github.com/tniessen/node-pqclean/blob/b494842a617e8fe094010c2194c25fe61bf052c9/.github/workflows/ci.yml#L28-L32

If you want to build the WebAssembly file locally, I would recommend to use the same version of Emscripten (3.1.21).

Unfortunately, the Emscripten SDK will also populate your PATH with an old version of Node.js, which might cause other problems. As a temporary workaround, until we figure out a better solution, you can skip the build-wasm step and use pre-built binaries instead:

$ git clone --branch v0.3.1 https://github.com/tniessen/node-pqclean.git
$ mkdir -p wasm/gen
$ curl -o wasm/gen/algorithms.json "https://unpkg.com/pqclean@0.3.1/wasm/gen/algorithms.json"
$ curl -o wasm/gen/pqclean.wasm "https://unpkg.com/pqclean@0.3.1/wasm/gen/pqclean.wasm"
$ npm run build-web
$ npm run test-web chrome

The last step is optional and only necessary for testing.

We will try to find a better solution to this issue. I have previously considered publishing the web distribution to npm directly to make this easier.

@tniessen Thank you for your attention, pre-build binaries works Should i close the issue?

tniessen commented 1 year ago

Please keep it open as a reminder for me to either update the documentation or to find a better solution :)
