WASM files in the JS API

VictorBerchet — Thu, 08 Apr 2021 17:25:56 GMT

It seems that there are 2 wasm files in 4.19

One of them seems to be handling i3s (from its name) and weights 700kB.

Is is possible to split WASM files in smaller modules and load them are required as opposed to have to load 700k ?

The I3S related WASM file should only be loaded on demand, meaning when loading scene layers in a scene. Can you confirm or have you witnessed any different behavior?

I haven't checked yet. I was only wondering if the file could be split in smaller modules, i.e. are 700kB of wasm required for all i3s or would a subset of that be enough for most use cases ?

Please let us know if something doesn't work as expected. However the WASM module contains various I3S related functionality so it will be loaded once you use scene layers. Splitting that up does make sense, I'll bring it up with our team 👍
