Jupyterlab 3.x.x support

With a fresh install of Jupyterlab version 3.0.0, installing plotly with the command jupyter labextension install jupyterlab-plotly@4.14.1 yields an error:

An error occured.
ValueError: 
"jupyterlab-plotly@4.14.1" is not compatible with the current JupyterLab
Conflicting Dependencies:
JupyterLab                        Extension      Package

Obviously this is a bleeding edge issue and very much a feature request, not a bug, I just wanted to make sure it was documented. Thank you!

Thanks @jasongrout! We’ll look at getting JupyterLab 3.x support in the next week or so.

I’ve tested locally by cloning plotly.py repo and modifying the package.json line 34 to:

"@jupyterlab/rendermime-interfaces": "^1.3.0 || ^2.0.0  || ^3.0.0",

So far so good, no issues.

So steps to try that workaround:

• install jupyterlab v3 (i recommend conda to do this) and plotly

conda install -c conda-forge jupyterlab

• install nodejs (i used my local version v12 but >v12 should work too).
• run jupyter labextension install jupyterlab-plotly@4.14.1 you will get the same error as @bdecato said:

An error occured.

• clone plotly.py repo in another folder (TMP, EXT whatever … ) and open the correct folder for the extension

mkdir EXT
cd EXT
git clone https://github.com/plotly/plotly.py.git
cd .\plotly.py\packages\javascript\jupyterlab-plotly\

• modify package.json line 34 to

"@jupyterlab/rendermime-interfaces": "^1.3.0 || ^2.0.0  || ^3.0.0",

• Build the extension and install; Inside this folder run:

npm instal
npm run build 
jupyter labextension install

• once it finishes, check the extension list:

jupyter labextension list

returns something like:

JupyterLab v3.0.0
Other labextensions (built into JupyterLab)
   app dir: C:\XXXXXXX\YYYYYY\jupyter\lab
        @jupyter-widgets/jupyterlab-manager v3.0.0 enabled ok
        jupyter-matplotlib v0.7.4 enabled ok
        jupyterlab-plotly v4.14.1 enabled ok*


   local extensions:
        jupyterlab-plotly: C:\XXX\EXT\plotly.py\packages\javascript\jupyterlab-plotly

Ready to test v3 compat !
