browser-esm-esbuild: not bundle index.js

[erosman]

I have generated the bundle as per browser-esm-esbuild and it runs fine with the included index.html.

build.js bundles index.js in the final bundled file.
The result is that importing the bundled index.js, it will look for document.getElementById('container') and runs into error if not found.
If found, it creates a new editor instance.
Neither of the above are desirable as the goal is to create a new editor in a different HTML document.

If I set bundle: false, in build.js, esbuild no longer includes all the necessary files`.

What is the proper way to handle this situation?
