Javascript runs out of memory when making production build

When I try to build a prod version of my create-react-app (and hence webpack) using npm run build, I get the following error:

<— Last few GCs —>

The production version builds fine when I use --max_old_space_size=8192 and takes about ~2 mins to build.

Here’s a sandbox for reference: https://codesandbox.io/s/381yjyn415

I’ve taken the liberty of adding all the dependencies that I use in my project.

@arshbhatti8 yes, you can use react-plotly.js with different bundles - see this section of its readme: https://github.com/plotly/react-plotly.js#customizing-the-plotlyjs-bundle

Closing as this ticket won’t directly lead to any PRs in this repo.

@arshbhatti8 if you any other issues with react-plotly.js + custom plotly.js bundles, please use our community formus at https://community.plot.ly/c/plotly-js

Thank you!
