Parallel IO Tasks

[MalQaniss]

If we let's say want to send parallel requests with "Promise.all" would this be a fine way:

const planetsNums = ['1','2']
const getPlanet = num => IO(() => fetch(`https://swapi.dev/api/planets/${num}`).then(response => response.json()))

const data = await Promise.all([...planetsNums.map(num => getPlanet(num).run())])
console.log(data)

Essentially, yes.

There's a helper in the IOHelpers module for this specific use-case, called waitAll(..). You'd use it in your example like this:

const planetsNums = ['1','2']
const getPlanet = num => IO(() => fetch(`https://swapi.dev/api/planets/${num}`).then(response => response.json()))

const data = await waitAll( ...planetsNums.map(getPlanet) ).run();
console.log(data);
