it-parallel-batch
Process (async)iterable values as functions with concurrency control
About
Takes an async iterator that emits promise-returning functions, invokes them in parallel and emits the results in the same order as the input.
The final batch may be smaller than the batch size.
Example
import parallelBatch from 'it-parallel-batch'
import all from 'it-all'
import delay from 'delay'
const input = [
async () => {
await delay(500)
return 1
},
async () => {
await delay(200)
return 2
},
async () => {
await delay(100)
return 3
}
]
const batchSize = 2
const result = await all(parallelBatch(input, batchSize))
console.info(result)
