interruptor

interruptor – Run a function with the possibility to interrupt it from another thread

Usage Example

import { runInterruptible, interrupt } from 'interruptor';
runInterruptible(handle => {
  // pass handle to another thread using .postMessage();

  while(true);
});

// In another thread:
interrupt(handle);

Caveats

This is a native addon, and currently no pre-built binaries are available.

This only interrupts synchronous execution inside the callback, not async functions (although the microtaskMode option for the vm module in Node.js 14 and above can help with Promises here).

This will not fully interrupt the running code, and not run any catch or finally blocks. In particular, if a module is being loaded at the time of interruption, the incomplete module may remain in the module loader cache.
