it-parallel
Process incoming async(iterable) functions in parallel
About
Takes an (async) iterable that emits promise-returning functions, invokes them in parallel up to the concurrency limit and emits the results as they become available, optionally in the same order as the input
Example
import parallel from 'it-parallel'
import all from 'it-all'
import delay from 'delay'
// This can also be an iterator, async iterator, generator, etc
const input = [
async () => {
console.info('start 1')
await delay(500)
console.info('end 1')
return 1
},
async () => {
console.info('start 2')
await delay(200)
console.info('end 2')
return 2
},
async () => {
console.info('start 3')
await delay(100)
console.info('end 3')
return 3
}
]
const result = await all(parallel(input, {
concurrency: 2
}))
// output:
// start 1
// start 2
// end 2
// start 3
// end 3
// end 1
console.info(result) // [2, 3, 1]
If order is important, pass ordered: true as an option:
const result = await all(parallel(input, {
concurrency: 2,
ordered: true
}))
// output:
// start 1
// start 2
// end 2
// start 3
// end 3
// end 1
console.info(result) // [1, 2, 3]
