set request mode to no-cors code example

Example 1: 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.
})

Example 2: redirect to website from promise value fetch

fetch("http://example.com/", {
	method: 'POST',
	mode: 'cors',
	body: formData
})
.then(dataWrappedByPromise => dataWrappedByPromise.text())
.then(data => {
	//Redirect is the URL inside the text of the response promise
	window.location.replace(data);
})
