I have an array of category ids in order, I have to make a map and fetch the items from these categories and in the end keep the original order of the array
what I've been doing:
const info = []
Promise.all(categoryItem.next_steps.map((next_step) => {
return categoryItemSvcV2.getAllItensNoOrderByCategoryId(next_step.category, idpage)
.then((result) => {
info.push(result)
})
})).then(() => {
res.json({ success: true, info })
})
the categoryItem.next_steps is the array of categoryIds on order, however each time I call this function it displays in an order
Promise.all does this out of the box, don't bring your own array:
Promise.all(categoryItem.next_steps.map(next_step =>
categoryItemSvcV2.getAllItensNoOrderByCategoryId(next_step.category, idpage)
)).then(info => {
// ^^^^
res.json({ success: true, info })
});
As you're using Promise.all, you don't need to create a separate array. Looking at your code above, this should work
const values = await Promise.all(
categoryItem.next_steps.map((next_step) =>
categoryItemSvcV2.getAllItensNoOrderByCategoryId(next_step.category, idpage)
)
);
res.json({ success: true, values });
