JSON-server. Filter by nested value

Question

I have DB (use json-server) like this:

DB = {
  products: [
    {id: 0, name: 'aaa', price: 10},
    {id: 1, name: 'bbb', price: 20},
    {id: 2, name: 'ccc', price: 50},
    {id: 3, name: 'ddd', price: 1}
  ]
};

And array of ids:

cartItemsIds: [0, 3];

How can I get array of objects from DB with ids from cartItemsIds ?

Does this answer your question? How to filter an array from all elements of another array — arizafar

Not exactly. This method should be work, but I know that json-server has inline filter feature. So there's no need to load all db.products, but filter them on server side. — Eduard Virchenko

Solved. If anyone needs:

`products?id=${cartItemsIds.join('&id=')}`

You can loop over your products from db like so:

for(const product of DB.products) {    
  if(cartItemsIds.includes(product.id)) {
   console.log(product);
  }
}

I don't want to get all DB.products and then filter them, but I want to filter them on server side at first and then get filtered array of objects.

my bad. I took a fast look to the docs. have you tried doing something like /products/id_like=${carItemsIds}?

or /products/id_like=${carItemsIds.join(',')}?

It needs to right request, request that you propose doesn't work even if carItemsIds contains only one element. But thanks for answer:)
