Hello Developers! All we are using either Axios OR fetch to communicate/exchange data with server. Both works perfect as per your requirement. Today we will go in detail and see how they are differ in terms of features they provide.
1. Request URL
Axios — has url in request object
axios
.get(url, {
headers: {
'Content-Type': 'application/json',
},
timeout: 1000 * 60,
})
.then(res => {
})
.catch(err => {
})
Fetch — has no url in request object.
fetch(url)
.then((response) => response.json())
.then((json) => {
})
.catch(() => {
})
2. Package
Axios — third-party package that you need to install manually. 85.3k Star in Github — Well managed & rich features library.
npm i axios
Fetch — is in-build into most of the browser, no more need of installation.
3. CSRF Protection
Axios — having in-build support of CSRF (Cross site request forgery) to prevent cross-site request.
Fetch — doesn’t support CSRF
4. Request Data
Axios — request data contain object, you can directly sent JSON Object in request data
axios
.post(url, jsonObject, {
headers: {
method: "POST",
headers: {
"Content-Type": "application/json",
},
},
timeout: 1000 * 60, // 1 min
})
.then((res) => {
if (res) {
return res.data;
}
})
.catch((err) => {
return err;
});
Fetch — request data should stringify
fetch(url, {
method: "POST",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify(jsonObject),
})
.then((response) => response.json())
.then((json) => {
})
.catch(() => {
});

5. Response Parsing
Axios — in-built transform response to JSON for
developers
axios
.post(url, jsonObject, {
headers: {
method: 'POST',
headers: {
'Content-Type': 'application/json',
},
},
timeout: 1000 * 60, // 1 min
})
.then(res => {
if (res) {
return res.data; // Directly get JSON in Step - 1 Only - Managed by Axios
}
})
.catch(err => {
return err;
})
fetch — has two step process, first response convert to json and then in second process developer will get json response
fetch(url, {
method: 'POST',
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify(jsonObject)
}).then((response) => response.json()) // Response Convert To JSON in this Step - 1
.then((json) => {
// Get JSON Object Here in Step - 2
})
.catch(() => {
})
6. Cancel Request
Axios — In case user left the screen/component, axios allow developers to Cancel request
const cancelTokenSource = axios.CancelToken.source();
axios.get('/listing/1', {
cancelToken: cancelTokenSource.token
});
// Cancel request
cancelTokenSource.cancel();
Fetch - doesn’t support Cancel API request
Fetch — doesn’t support Cancel API request
7. Request Interceptor
Axios — having in-build feature of intercept HTTP Request
Fetch — Doesn’t provide a way to intercept http requests.
8. Upload/Download Request Progress
Axios — Support developers to provide data transmission progress so developers can show loading indicator while user communicating with server
Fetch — Doesn’t support Upload/Download progress
9. Browser Support
Axios — have side browser capability support
Fetch — only support limited browsers & version , like Chrome 42+, Firefox 39+, Edge 14+, Safari 10.1.
