LocalStorage not working after storing token - reactjs

Question

I am storing JWT token in LocalStorage after Login success is dispatched and routing to next component. But the next component API call is not able to take LocalStored token.
If i refresh the page and click again, it is accepting the token. Dont know the issue.
This is Axios Instance and Login Dispatch respectively
const instance = axios.create({
headers: {
'Accept': 'application/json',
'Content-Type': 'application/json; charset=utf-8',
'x-access-token': localStorage.getItem('accessToken'),
},
withCredentials: true,
validateStatus: (status) => status === 200
});
export function checkLogin(data, history) {
return function (dispatch) {
return dispatch(makeAPIRequest(loginAPI, data)).then(function (response) {
if (response.data.success == 1) {
localStorage.removeItem('accessToken')
localStorage.setItem('accessToken', response.data.data.token)
dispatch({ type: STORE_SESSION_TOKEN, authenticated: response.data.data.auth, token: response.data.data.token,userDetails: response.data.data.user });
history.push('/dashboard')
}
})
}
}
Expecting to take token from Localstorage from very next call from Dashboard. But that doesn't happen. says no token and redirects to Login

I think the problem is when you create the axios instance, the token is not available in localStorage.
You should try the default headers of axios:
export const AUTHORIZATION = 'authorization'
export const API = axios.create({
baseURL: `http://localhost:3000/api`
})
export const authorize = (token) => {
if (token) {
API.defaults.headers.Authorization = `Bearer ${token}`
localStorage.setItem(AUTHORIZATION, token)
}
}
export const unauthorize = () => {
delete API.defaults.headers.Authorization
localStorage.removeItem(AUTHORIZATION)
}
authorize(localStorage.getItem(AUTHORIZATION))
When you receive the token from the API in your actions, you have to save it to localStorage.

You need to get your header dynamically, because the token is not there while creating the instance and it might change later:
const JSON_HEADERS = {
'Accept': 'application/json',
'Content-Type': 'application/json; charset=utf-8'
};
const getTokenFromStorage = () => localStorage.getItem('token');
const getHeaders = () => getTokenFromStorage().then((token) => {
if (!token) {
return JSON_HEADERS;
}
return {
... JSON_HEADERS,
'x-access-token': token
};
});
export const makeAPIRequest = ({ method, url, data }) => {
return axios({
method,
url,
data,
headers: getHeaders()
});
}
