I'm using ttest nodejs module in application. Due to updates to it I tried to use updated version ttest@2.0.0. When module start compute data the error appears:

ReferenceError: WebAssembly is not defined

The NodeJS version - 6.9.1.

Error appears in next place:

class CephesWrapper {
  constructor(sync) {
    // Initialize the runtime's memory
    this._wasmMemory = new WebAssembly.Memory({
      'initial': TOTAL_MEMORY / WASM_PAGE_SIZE,
      'maximum': TOTAL_MEMORY / WASM_PAGE_SIZE
    });
.....
  }
}

Is there any advices about solving this issue? Is it possible to define WebAssembly?

The WebAssembly support is added in NodeJs 8.0.0. Update your NodeJS to make it work.

In my case, the problem was that I was running my browser in safe mode (Mozilla Firefox). Simply shutdown your browser completely and restart. This will quit safe mode (If stuck in safe mode, see here)

For reference, I had found this solution here : https://github.com/mozilla-iot/gateway/issues/2047

Even my node version was 12, and npm version was 6. I was getting the reference error for webassembly.

So I updated the node with latest version(16), it changed the npm version also. Now the reference issue is fixed.

D:\ReactJS\react_demo>node -v

v16.14.0

D:\ReactJS\react_demo>npm -v

8.3.1
