Toggle on to catch emitted values from source, toggle off to emit buffered values as array.
Examples
Example 1: Toggle buffer on and off at interval
( | | )
// RxJS v6+
import { interval } from 'rxjs';
import { bufferToggle } from 'rxjs/operators';
//emit value every second
const sourceInterval = interval(1000);
//start first buffer after 5s, and every 5s after
const startInterval = interval(5000);
//emit value after 3s, closing corresponding buffer
const closingInterval = val => {
console.log(`Value ${val} emitted, starting buffer! Closing in 3s!`);
return interval(3000);
};
//every 5s a new buffer will start, collecting emitted values for 3s then emitting buffered values
const bufferToggleInterval = sourceInterval.pipe(
bufferToggle(startInterval, closingInterval)
);
//log to console
//ex. emitted buffers [4,5,6]...[9,10,11]
const subscribe = bufferToggleInterval.subscribe(val =>
console.log('Emitted Buffer:', val)
);
Example 2: Toggle buffer on and off on mouse down/up
