Support for JupyterLab 2.1

[fzimmermann89]

Hi,

are there any plans to publish an update that's compatible with JLab >=2.0 ?

Thanks :)

I second this. Just installed Jupyterlab and got the following error

I reinstalled Jupyterlab with version 2.0 but still get the same error message. Quite inconvenient as I was very much looking forward to using the viewer in jupyterlab! There aren't that many HDF viewers out there..

I am also looking forward to have this extension with the latest version of Jupyterlab. Is there any progress?

I attempted to simply hack config.json and rename lumino, but with no luck. As a longtime notebook user but new lab user, I did not expect to find that this apparently official extension is currently bricked. I was also rather disappointed that both the current state and future of this extension is unclear.

Adding my voice here: I too would like to have an HDF5 viewer in current and future JupyterLabs.

I tried to update my local clone to make it work with JL 2.1+, and found out except for updating @phosphor libraries with @lumino, the dependencies

"@jupyterlab/dataregistry": "^3.0.0",
"@jupyterlab/dataregistry-extension": "^3.0.0",

don't support JL 2.1+ yet, which was brought up in jupyterlab/jupyterlab-data-explorer#138

I installed the master branch of jupyterlab-data-explorer (which supports JL 2.1) and tried to install jupyterlab-hdf5 using NPM local dependencies

"@jupyterlab/dataregistry": "file:../jupyterlab-data-explorer/packages/dataregistry",
"@jupyterlab/dataregistry-extension": "file:../jupyterlab-data-explorer/packages/dataregistry-extension"

But I encountered the error

npm ERR! code ENOENT
npm ERR! syscall access
npm ERR! path /github/jupyterlab-data-explorer/packages/dataregistry-extension/node_modules/@types/react
npm ERR! errno -2
npm ERR! enoent ENOENT: no such file or directory, access '/github/jupyterlab-data-explorer/packages/dataregistry-extension/node_modules/@types/react'

Seems it relates to the jupyterlab-data-explorer packaging structure (node_modules in the root folder, then the individual packages in /packages)

Any suggestions on how to proceed with my local installation? I would love to help update the hdf5 extension to support JL 2.1+.

@cnydw, did you build the jupyterlab-data-explorer using jlpm build ?

Because, following your tries, I managed to build the extension on JupyterLab 2.1 by installing the jupyterlab-data-explorer extensions from the master branch, updating all @jupyterlab dependencies in package.json and replacing @phosphor by @lumino.

I also had to fix some IRegistry imports.

The resulting extension (https://github.com/loichuder/jupyterlab-hdf5/tree/jupyter2.1) is then available in my JupyterLab instance but I get the Directory not found error described in #29 when clicking on hdf5 files.

I tried on JupyterLab 2.2 and this time, I do not get the Directory not found error but I am unable to explore any data. I get blank pages instead of data grids (see below) and I get DOMException: An attempt was made to use an object that is not, or is no longer, usable in the browser console.

The latest v0.4.0 release now includes support for juptyerlab 2.x (tested with the latest jlab v2.2.7 release).

@fzimmermann89 @pablooriol2 @snmhas @nitrocalcite @athornton @cnydw @loichuder Please try out the standard jupyterlab-hdf install:

pip install jupyterlab_hdf
jupyter labextension install @jupyterlab/hdf5

and let me know if you run into any further troubles in a fresh issue
