This commit updates the documentation for the WASM examples to include a note about the generation of the `worker.js` file. As of Emscripten 3.1.58 (April 2024), separate worker.js files are no longer generated and the worker is embedded in the main JS file. The motivation for this change is to inform users about the new behavior of Emscripten and why the `worker.js` file may not be present. Refs: https://github.com/ggml-org/whisper.cpp/issues/3123

bench.wasm
Benchmark the performance of whisper.cpp in the browser using WebAssembly
Link: https://ggerganov.github.io/whisper.cpp/bench.wasm
Terminal version: examples/bench
Build instructions
# build using Emscripten (v3.1.2)
git clone https://github.com/ggerganov/whisper.cpp
cd whisper.cpp
mkdir build-em && cd build-em
emcmake cmake ..
make -j
The example can then be started by running a local HTTP server:
python3 examples/server.py
And then opening a browser to the following URL: http://localhost:8000/bench.wasm
To run the example in a different server, you need to copy the following files to the server's HTTP path:
# copy the produced page to your HTTP path
cp bin/bench.wasm/* /path/to/html/
cp bin/libbench.js /path/to/html/
cp bin/libbench.worker.js /path/to/html/
📝 Note: As of Emscripten 3.1.58 (April 2024), separate worker.js files are no longer generated and the worker is embedded in the main JS file. So the worker file will not be geneated for versions later than
3.1.58.
