How do I store a fetch response to a derived store in svelte?

I have a list of items which I consume from an own custom built API (in the example I’ll use typicode) and want to display them. Additionally I want to add a client side search functionality. It is exactly like this REPL from this question.

But the given list is hardcoded, yet I can’t seem to build a fetch call to get those items prior and afterwards display them. Only then can the user search and filter them.

Here is my REPL.

>Solution :

response.json() returns a promise, so you should await it.
