How do you import something different in tests vs release?

[jonathanpeppers]

Is your feature request related to a problem? Please describe.

In tests, we'd like to use:

import * as ort from 'onnxruntime-node';

But in the actual browser extension:

import * as ort from 'onnxruntime-web';

Is there a way to do this?

Describe the solution you'd like

Point me to a JavaScript / extension-cli example on how to do this?

Additional context

I have mostly a C#/.NET/Java background, so I really have no idea about JavaScript. Any suggestions will help a lot! Thanks!
