index.html not updated on deployment

[Kim-Andersen]

Hi,
First of all, thanks for creating this build pack. I much appreciate the super easy setup and deployment of a create-react-app on Heroku using this.

That said, I'm experiencing a deployment issue where it seems index.html is not updated, and I suspect nginx cache has something to do with this, in a joined effort with the service worker.

Do you have any suggestion on how to tackle this issue?

Thanks in advance.

I solved it by configuring a cache header in static.json:
"headers": { "/**": { "Cache-Control": "no-store, no-cache" } }

index.html is still served from the service worker on subsequent requests, which is the desired behavior.

Maybe you want to add this cache header as a default in static.json?

Don't we only need to add cache-control to index.html?

Yes @bsiddiqui, cache-control: no-cache should only be applied to index.html. By eliminating cache for all files, performance of the React app will suffer. Create React App uniquely hashes each bundle name so that the static assets can be aggressively cached.
