Error: Cannot create URL for blob!

located: src/lib/client.ts
method: _setupPingTimer
class: PingTimer
init: getTimer(variant) = getTimer('auto')

Description:

The error is caused for the library worker-timers when the class PingTimer call getTimer('auto') method. This method getTimer doesn't recognize it's executed in ReactNative (RN), it know it's executed in a browser, but RN implements its own timers as: setTimeOut, setInterval, etc., when is called the method workerTimer instead nativeTimer the library worker-timers that implement Blob to store data or whatever it does, throw the next error: [Error: cannot create URL for blob!], Blob it isn't supported by RN.

Fix:

To support ReactNative (RN) it's necessary install 2 package additionals to RN projects:

• buffer
• url

Also include the next code at beginning of the program:

process.nextTick = (callback) => { setTimeout(callback, 0) }

Conclusion

I have the commit of the fix of this bug, please @robertsLando allow me create a PR and show you my solution.

I will attach my mqtt client connection and the files I changed in this package to fix the bug:

mqtt_client_example.txt
is-browser.txt
get-timer.txt
shared.txt
BufferedDuplex.txt

Feel free to open the PR, anyway this could be fixed easily by using timerVariant: 'native' in connect options

I think so, also I made the changes in that way because if isn't imported Buffer library, later I need to put Buffer library in the global scope in RN projects, something like this:

Object.assign(global, { Buffer: require('buffer').Buffer });

This is the PR #1840
