N-API C++ addon causing Electron GUI to block

QUESTION

N-API C++ addon causing Electron GUI to block

Asked 2019-Mar-12 at 11:40

I have an N-API C++ addon that I would like to use with an Electron GUI. Currently the C++ addon has a simple function that sleeps for 10 seconds and then performs a computation of 8*2, and returns the value to the Javascript code. The Javascript code runs the C++ addon every 10 seconds.

...

ANSWER

Answered 2019-Mar-12 at 11:40

The reason it blocks Electron is the sleep(10). That call doesn't return for 10 seconds.

So yes, there is a way to offload heavy computation to another thread. The biggest complication from doing so is that the thread can't make a callback to JavaScript without taking extra precautions nor can the thread access JavaScript data structures, so it must be provided with all the data necessary.

Here's the example the C++ abstraction provides for N-API using a thread to calculate Pi.

And here are C++ wrappers to create thread-safe callbacks.

It's not trivial but these two examples should get you through it.
