Promise performance profiling

A simple tool for profiling the performance of Promises in the browser. Useful for debugging what takes so long between the user presses a certain button and and action following a complex async/await flow.

This won't work with native/untranspiled async functions, only with babel generated code. Use with Chrome.

Usage

The package changes the global object, so all you have to do is import it

import 'promise-performance';

Then, to see profile information, call window.getPromiseProfiles() in your devTools, and reset the timers by calling window.resetPromiseProfiles().

Happy profiling.
