Javascript error handling can sometimes be confusing especially in using fetch, if you are using await
you will need to wrap it in a try
catch
block to handle the error and we all know that it's a headache
Well what if i tell you we can do something like this
import { get } from "./eavfetch";
interface Book {
id: string;
title: string;
author: string;
}
async function fetchBooks() {
// data type is inferred as Book[]
const [data, error] = await get<Book[]>("/books");
if (error) {
console.error("Failed to fetch books:", error);
return;
}
if (data) {
console.log("Fetched books:", data);
}
}
Now all of the sudden handling fetch
seems easy and very straightforward and safe way to handle error and data right? Well that's the power of error as values approach
you can copy the eavfetch.ts/js
in the repo and start using it right away.
