Thanks @Tobbe,
I had already had a look at that, and I can see the main culprits, I guess what I’m a bit lost on is how to actually effect the size of this bundle and start breaking it up. As I mentioned from what I read in the docs I thought that redwood apps were by default code-split per page, but commenting out routes didn’t change this bundle at all. I’ve also tried lazy the bigger modules with cost modulePromise = import('cool-module') but this hasn’t change the bundle either, I can still see these modules in that chunk.
I guess I need to configure webpack to code-split when using the import function?
