TIL Multiple Fetch Requests

POSTED ON:

TAGS:

I've been frequently dealing with this scenario in the past few weeks.

I wanted to make multiple fetch requests, and then merge everything together when it's all done.

To make multiple/parallel fetch requests:

async function fetchMoviesAndCategories() {
const [moviesResponse, categoriesResponse] = await Promise.all([
fetch('/movies'),
fetch('/categories')
]);
const movies = await moviesResponse.json();
const categories = await categoriesResponse.json();
return [movies, categories];
}
fetchMoviesAndCategories().then(([movies, categories]) => {
movies; // fetched movies
categories; // fetched categories
}).catch(error => {
// /movies or /categories request failed
});

ONE THING TO NOTE: Encrypting a script is stronger than obfuscation, both methods are still not adequate to protect secret content. Honestly, I don't think it's worth it on a production site, and instead just go with pure server-side if you want security. But it's fascinating.
