clustergrammer not working inside an Electron app

[wasimaftab]

I am trying to use clustergrammer inside an electron app but I am getting Uncaught TypeError: Cannot read property 'getComputedStyle' of null (See screenshot below)

I've followed the instructions from the official page which describes how to use clustergrammer in a web page.

My package.json looks like below,

To reproduce this issue I've created a minimal repo in GitHub. First, execute yarn install inside the repo folder to install the node modules and then execute yarn start to launch the app.

My OS is Ubuntu 20.04 and using node version 14.16.1

Is it a bug or I am missing something? I will appreciate your suggestions

Hi @wasimaftab, thanks for raising the issue. I ran your test_clustergrammer_app and I see the same error. The error occurs in D3 at this line

   		var container_width = d3.select(params.root).style('width').replace('px', '');
   		var container_height = d3.select(params.root).style('height').replace('px', '');

So, I am guessing that the params.root value may not have been set correctly. We also have a WebGL version of Clustergrammer here Clustergrammer-GL - see example ObservableHQ notebooks
