CSRF:

Cross-Site Request Forgery (CSRF) is a type of security vulnerability that occurs when an attacker tricks a user's browser into making an unintended and unauthorized request to a web application on which the user is authenticated. This can lead to actions being performed on behalf of the user without their consent.

Create the instance of axios

const axiosInstance = axios.create({
    baseURL: 'https://jsonplaceholder.typicode.com',
    timeout: 2000,
    headers: {
        'Content-Type': 'application/json'
    }
}); 

//now every axios request should be like
axiosInstance.get(config);

Ways to make axios request.

//using the promise for client side.
const res = axios({
     method:'get',
     url:'relative url'
)}
.then( res => console.log(res.data))// on sucessfull
.catch( err => console.log(err)) //On error
.finally(res => /*do whatever whatever be the response*/)//on everyTime

//using the async await function 
//basically for server side 
async function getData(){
try{
     const res = await axiosInstance({
            method: 'get',
            url: '/todos/a'
        })
   console.log(res.data);
 }
    catch (err) {
        console.log(err);
    }
};
