Is there a way to merge all JS build files in only one bundle?

[guilhermeutzig]

Hey guys, enjoying a lot my experience here with Gatsby, it's really nice!

There is something I want to know, when I run gatsby build, it generates a ton of files on public directory:

Is there a way to envolve all of this in a single bundle file?

Thanks!

No, this is by design to enable code splitting and other optimizations which make Gatsby so fast.

@LekoArts Ok, thanks for your answer! Closing this issue.

We did move js/css files into their own directory recently #6346

It would be great if there was an option to bundle it all into one file, because right now offline support (with gatsby-plugin-offline is less than ideal because the individual route files only get cached/saved when a visitor visits them, and then when the app is updated they lose those again.

It would be so nice if there was an option to have one big bundle that a service worker could cache, and then you could automatically have a fully offline-available site.

I asked a question along those lines eariler here but there was no response, and it was automatically closed.

I'm using gatsby as a single page application generator, so I only have one page.

In this case, having one file (and one request) instead of 4-5 would be the more performant route. Shouldn't be too hard to have an option/plugin that just appends the JS file and give this as an option.
