What is difference between Axios and Fetch?

Question

I am calling the web service by using Fetch but the same I can do with the help of Axios. So now I am confused. Should I go for either Axios or Fetch?

Answer 1

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)

Also, if you work with JSON requests, the following are some differences I stumbled upon with.

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 } 

So:

• 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 object.
