Aggregates several async iterators into one (zip)
import { aggregateRoundRobin, aggregateFifo } from "aggregate-async-iterator";
async function* sequence(name, time = 100, num = 10) {
for (let i = 0; i < num; i += 1) {
yield new Promise(resolve => setTimeout(resolve(name + i), time));
}
}
console.log("RR:");
for await (const r of aggregateRoundRobin([
sequence("A", 100, 3),
sequence("B", 35, 5)
])) {

}
console.log("FIFO:");
for await (const r of aggregateFifo([
sequence("A", 100, 3),
sequence("B", 35, 5)
])) {
console.log(r);
}Prints interleaved sequences

B4Aggregate items from sevaral async iterators into one. Items are collected first in first out from the sources. Whatever source comes first will be delivered first.
-
sourcesArray<AsyncIterator<any>>
Returns AsyncIterable<any> items collected from all sources
Aggregate items from sevaral async iterators into one. Items are collected round robin from the sources. The 2nd. round of items will only be delivered after all sources have delivered their 1st. round (or reached their end).
-
sourcesArray<AsyncIterator<any>>
Returns AsyncIterable<any> items collected from all sources
