JavaScript: quick start with script tag does not work in ESM mode

[fdb]

I'm trying to run the JavaScript examples, starting from the quick-start_onnxruntime-web-script-tag directory. This directory contains two versions:

• index.html, which runs perfectly and produces no errors.
• index_esm.html, which does not run and throws an error.

This is the error:

failed to inference ONNX model: Error: no available backend found. ERR: [wasm] RuntimeError: Aborted(LinkError: import object field 'J' is not a Function). Build with -sASSERTIONS for more info., [cpu] Error: previous call to 'initializeWebAssembly()' failed., [webnn] Error: previous call to 'initializeWebAssembly()' failed., [xnnpack] Error: previous call to 'initializeWebAssembly()' failed..

Output of index_esm.html:

Output of index.html:

Environment

The error appears in Firefox, Chrome and Safari. I'm running this on a MacBook Pro M2 Max in macOS Sonoma 14.2.1.

@fs-eire, could you please help take a look?

The reason why this does not work is because the file dist/esm/ort.min.js is not yet available in latest release version. The document is updated before the release is done. Sorry for the inconvinience.

If you specify the explicit version number, it will work. For example, replace the lines to:

            // import ONNXRuntime Web from CDN
            import * as ort from "https://cdn.jsdelivr.net/npm/onnxruntime-web@1.18.0-dev.20240124-d7aebf9ea8/dist/esm/ort.min.js";
            // set wasm path override
            ort.env.wasm.wasmPaths = "https://cdn.jsdelivr.net/npm/onnxruntime-web@1.18.0-dev.20240124-d7aebf9ea8/dist/";

onnxruntime-web@1.17 will release soon, and then you will not have this issue.
