fetch on error js

Add no cores to fetch

// There were no quick access to mode and credentials to other fetch answers.
// Data you'll be sending
const data = { funny: "Absolutely not", educational: "yas" }

fetch('https://example.com/api/', {
  method: 'POST', // The method
  mode: 'no-cors', // It can be no-cors, cors, same-origin
  credentials: 'same-origin', // It can be include, same-origin, omit
  headers: {
    'Content-Type': 'application/json', // Your headers
  },
  body: JSON.stringify(data),
}).then(returnedData => {
  // Do whatever with returnedData
}).catch(err => {
  // In case it errors.
})

function CheckError(response) { if (response.status >= 200 && response.status <= 299) { return response.json(); } else { throw Error(response.statusText); } } // Now call the function inside fetch promise resolver fetch(url) .then(CheckError) .then((jsonResponse) => { }).catch((error) => { });

fetch('https://apiYouWantToFetch.com/players') // returns a promise .then(response => response.json()) // converting promise to JSON .then(players => console.log(players)) // console.log to view the response

export async function getStaticProps(context) { const res = await fetch(`https://...`) const data = await res.json() //use this statement for the program not to crush but go back to the home page if (!data) { return { redirect: { destination: '/', permanent: false, }, } } return { props: {}, // will be passed to the page component as props } }
