});how to use fetch() javascript
//Most API's will only allow you to fetch on their website.
//This means you couldn't run this code in the console on
// google.com because:
// 1. Google demands the fetch request be from https
// 2. open-notify's API blocks the request outside of their website
fetch('http://api.open-notify.org/astros.json')
.then(function(response) {
return response.json();
})
.then(function(json) {
console.log(json)
});
// Here is another example. A method (function) that
// grabs Game of Thrones books from an API ...
function fetchBooks() {
return fetch('https://anapioficeandfire.com/api/books')
.then(resp => resp.json())
.then(json => renderBooks(json));
}
function renderBooks(json) {
const main = document.querySelector('main')
json.forEach(book => {
const h2 = document.createElement('h2')
h2.innerHTML = `<h2>${book.name}</h2>`
main.appendChild(h2)
})
}
document.addEventListener('DOMContentLoaded', function() {
fetchBooks()
