react-native compatibility

[Czino]

I was already expecting while reading the README.md that I won't be lucky with react-native.

But I tried the sample integration and already hit the first error that happens somewhere here: bitbox02-api-go.js:

ERROR Error: runtime error: makeslice: len out of range

Is react-native compatibility planned or do you suggest including a webview as a workaround?

Could provide a minimal reproducible example that triggers the errro?
maybe even a git repo?

This is a go error, currently bitbox02-api-js is transpiled with gopherjs

that error is triggered by the makeslice function in the runtime, when the len argument of make( ) called on a slice is either negative of unreasonably big; e.g:

golang/go#38673

Thanks for not closing the issue.

So, I created this repository here.

At first it was not showing the original error, because of this problem:

[Error: Requiring module "node_modules/bitbox02-api/lib/bitbox02.js", which threw an exception: TypeError: undefined is not an object (evaluating 'argv.length')]

after adding this workaround

global.process.argv = []

I managed to force the above mentioned error. Hope it helps.

Would be great if Bitbox is also react-native compatible

Thanks for the repo ❤️ !! The transpiled go code is just so big 🙈

Running npm run android I got stuck at 97-98% bundling, so then I was looking at 2 things: increase memory for node with NODE_OPTIONS=--max_old_space_size=8192 npm run android
and ignore/exclude bitbox02-api module from babel.

This person has a similar issue with a big lib also using react native babel/babel#12231

For some reason I don't get stuck anymore at 98% building, but the emulator can't connect to the debugger.. here I am afraid I just don't have enough experience with react native. :(

If support cannot be guaranteed on the native level for react, do you think including a webview and loading the interface through it would be a viable workaround?

I will probably try it soon if there's no native solution by then.
