How to get all WordPress posts from the WP API in just two steps

Hello Everyone ✋
On my work, I was building a Gutenberg block to get all the posts and make with them a slider very simple thing 😝 but the problem starts when I was trying to show all posts on a dropdown where the client can choose the posts that want to show on the slider.

So if you have a case similar to me the code below will work just fine.

The first thing we will need to make a simple request and get the total amount of posts from WordPress.

   fetch('https://example.com/wp-json/wp/v2/posts?per_page=10', {
    }).then((response) => { 
        getAllPosts(response.headers.get('X-WP-Total'));
    });

The second thing for sure we will need to create the getAllPosts function which is going to request all posts.

const getAllPosts = (allPosts) => {

 fetch(`https://example.com/wp-json/wp/v2/posts?per_page=${allPosts}`)
  .then((response) => {
    return response.json();
 })
 .then((posts) => {
  console.log(posts);
 });

}

Now you can check your console to see if all the posts are present.
