Bundle Diffing, is it possible?

[longb1997]

Hi team,

We are using Re.Pack to build a mini-app architecture. To optimize our bundle updates and reduce download times, we are looking into Bundle Diffing (e.g., generating a bsdiff patch between the old and new bundles instead of downloading the full new bundle).

I have a quick question about its feasibility with Re.Pack:
Are Re.Pack's Rspack builds deterministic enough out-of-the-box (regarding module IDs and chunk hashes) to generate efficient diff patches for minor code changes?

Has anyone in the community successfully implemented bundle diffing for Re.Pack? Any insights or recommended Rspack configurations for strict determinism would be greatly appreciated!

Thanks!

For mini apps in module federation or just the overall js bundle?

It should be mini apps, but with Hermes bytecode
