Fetch vs Axios

Fetch JSON post request
let url = 'https://someurl.com';
let options = {
            method: 'POST',
            mode: 'cors',
            headers: {
                'Accept': 'application/json',
                'Content-Type': 'application/json;charset=UTF-8'
            },
            body: JSON.stringify({
                property_one: value_one,
                property_two: value_two
            })
        };
let response = await fetch(url, options);
let responseOK = response && response.ok;
if (responseOK) {
    let data = await response.json();
    // do something with data
}
Axios JSON post request
let url = 'https://someurl.com';
let options = {
            method: 'POST',
            url: url,
            headers: {
                'Accept': 'application/json',
                'Content-Type': 'application/json;charset=UTF-8'
            },
            data: {
                property_one: value_one,
                property_two: value_two
            }
        };
let response = await axios(options);
let responseOK = response && response.status === 200 && response.statusText === 'OK';
if (responseOK) {
    let data = await response.data;
    // do something with data
}
  • Fetch's body = Axios' data
  • Fetch's body has to be stringified, Axios' data contains the object
  • Fetch has no url in request object, Axios has url in request object
  • Fetch request function includes the url as parameter, Axios request function does not include the url as parameter.
  • Fetch request is ok when response object contains the ok property, Axios request is ok when status is 200 and statusText is 'OK'
  • To get the json object response: in fetch call the json() function on the response object, in Axios get data property of the response objec
Note: Fetch and Axios are very similar in functionality, but for more backwards compatibility Axios seems to work better (fetch doesn't work in IE 11 for example, check this post)
