Making WebGPU-NAPI addon @webgpu compliant

[dcerisano]

I just posted an update to your issue in CTS

Could you please create a cts-napi branch here to develop against the napi branch in CTS?

The basic issue is that there are slight differences in WebGPU API between these two repos that should be resolved. The idea to to make everything compliant with the @webgpu spec.

This will likely mean the addition of typescript to the examples here, to ensure the NAPI addon remains compliant and is instantly aware of changes to the @webgpu spec.

The CTS testing for WebGPU-NAPI is proceeding with Kai at Google.
Good news is many of the CTS tests are passing!

Getting an error here, looking into it now. Any suggestions?
I am using a fork of this repo that builds directly against Dawn (the July 10 version)

@dcerisano so you were able to reproduce that issue locally? What did you change to make that issue start happening?

I had the LD_LIBRARY path set to the latest build of Dawn. The binaries in the PR are from July 10. We need to roll upstream Dawn changes into WebGPU-NAPI on a regular basis. I included a build.sh in our fork that builds the July 10 version of Dawn (will make it a submodule eventually). Dawn does not have tags, so referencing by commit SHA for July 10.
