using .then() syntax
fetch('http://example.com/movies.json') .then((response) => { return response.json(); }) .then((myJson) => { console.log(myJson); });
Async function methodology
// Example POST method implementation: async function postData(url = '', data = {}) { // Default options are marked with * const response = await fetch(url, { method: 'POST', // *GET, POST, PUT, DELETE, etc. mode: 'cors', // no-cors, *cors, same-origin cache: 'no-cache', // *default, no-cache, reload, force-cache, only-if-cached credentials: 'same-origin', // include, *same-origin, omit headers: { 'Content-Type': 'application/json' // 'Content-Type': 'application/x-www-form-urlencoded', }, redirect: 'follow', // manual, *follow, error referrerPolicy: 'no-referrer', // no-referrer, *client body: JSON.stringify(data) // body data type must match "Content-Type" header }); return await response.json(); // parses JSON response into native JavaScript objects } postData('https://example.com/answer', { answer: 42 }) .then((data) => { console.log(data); // JSON data parsed by `response.json()` call });
