rn_bridge blocked nodejs mobile event processing

[microcai]

problem:

when dealing with async api, rn_bridge blocked node async event system, the Promise.then only gets called when you call channel.send() at android side next time.

way to reproduce:

android side:

channel.send( 'someevent1')

nodejs mobile side:

rn_bridge.channel.on('someevent1', (msg)=>{
some_async_api_that_returns_a_promise().then(
rn_bridge.channel.send('api-result'); // this never get called unless android calls channel.send some time later .....
)
})

since rn_bridge did not response a message immediately, the entire nodejs mobile thread got blocked, thus the promise is then blocked.
after android side calls channel.send again ( with what ever message ) the nodejs mobile thread runs again and dispatches the Promise.

Hi @microcai ,

From the calls you described in the issue description, you are using send(), which would only trigger a 'message' event instead of a 'someevent1' event, so this would not behave as you are expecting. I recommend reading the API: https://github.com/JaneaSystems/nodejs-mobile-react-native/tree/49c069539db138688a9e44c44180bb0c3335537c#methods-available-in-the-react-native-layer

This was fixed as discussed in the issue where you commented: #13

I'm currently unable to reproduce this issue. Could you please provide a project that reproduces the error?
