electron-plotly.js

Use electron to export plotly.js graphs as images.

How to run this thing?

• npm i
• npm start

If you’re on Ubuntu (or maybe some other Linux distro) and you have xvfb installed, you can run this things headlessly (no joke) with:

npm run start:headless

and see results in fig.png.

You can also pass as argument any URL to a plotly "data"/"layout" JSON or the name of the plotly.js test mock you’d like to export. For example:

npm start -- gl3d_bunny

How does this thing work?

Using electron the main module sends plotly.js "data"/"layout" JSON data to the renderer module. The renderer calls Plotly.plot and Plotly.toImage in succession and then sends the image data back to the main module it writes a PNG file.
