BokehJS and npm and embed_item()

I’m currently using BokehJS in my create-react-app by putting CDN links in my index.html. My preference is to do it via npm however when I do

import * as Bokeh from ‘bokehjs’;

``

Bokeh.embed.embed_item(plot_data)

``

I get a bunch of warnings from the import:

./node_modules/bokehjs/build/js/lib/models/tools/inspectors/customjs_hover.js

Is there any way to do an import from npm via create-react-app (i.e without modifying webpack which requires ejecting)?

Hi,

I'm currently using BokehJS in my create-react-app by putting CDN links in my index.html. My preference is to do it via npm however when I do

import * as Bokeh from 'bokehjs';

...

Bokeh.embed.embed_item(plot_data)

I get a bunch of warnings from the import:

./node_modules/bokehjs/build/js/lib/models/tools/inspectors/customjs_hover.js

./node_modules/bokehjs/build/js/lib/models/transforms/customjs_transform.js

this means that you won't be able to use require/imports in CustomJS
(etc.) snippets. One can use bokehjs without those, especially that
usually you can replace such snippets with JS functions.

And this error from the embed_item() call:

Thanks.

The solution appears to involve modifying webpack config, but from my (limited) understanding of create-react-app, webpack config can’t be modified without ‘ejecting’ the project which I’d rather avoid. I suppose I’m best to stick with the CDN approach at least for now, and I’ll watch that issue and see where it goes.
