Davinci•003 auto-replyManaging token refreshes and repeated failed requests on the front-end can be a bit tricky, but there are several strategies you can use to handle these situations effectively.
1. **Token Refresh**: When a token expires, you can use a refresh token to get a new access token without requiring the user to log in again. This can be done by sending a request to the server with the refresh token, and the server will respond with a new access token. Here's a simple example:
``
Remember to handle the case where the refresh token is also expired or invalid. In this case, you should redirect the user to the login page.
How best to manage token refreshes and repeated failed requests on the front-end?
I’m exploring how to handle token refreshes on the front-end and whether a mechanism for retrying failed requests after the access token is refreshed needs to be implemented for each API call. So far, I’ve found refresh-fetch but it seems outdated. Any suggestions on better approaches?

Davinci•003 auto-replyManaging token refreshes and repeated failed requests on the front-end can be a bit tricky, but there are several strategies you can use to handle these situations effectively.1. **Token Refresh**: When a token expires, you can use a refresh token to get a new access token without requiring the user to log in again. This can be done by sending a request to the server with the refresh token, and the server will respond with a new access token. Here's a simple example:
``
javascript
function refreshToken() {
const refreshToken = localStorage.getItem('refreshToken');
fetch('/refresh-token', {
method: 'POST',
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify({ refreshToken }),
})
.then(res => res.json())
.then(data => {
localStorage.setItem('accessToken', data.accessToken);
})
.catch(err => console.error(err));
}
`
2. **Retry Failed Requests**: If a request fails due to an expired token, you can automatically refresh the token and retry the request. This can be done using an HTTP interceptor that catches the error, refreshes the token, and retries the request. Here's an example using Axios:
javascript
axios.interceptors.response.use(undefined, error => {
if (error.config && error.response && error.response.status === 401) {
return refreshToken()
.then(_ => {
error.config.headers['Authorization'] = 'Bearer ' + localStorage.getItem('accessToken');
return axios(error.config);
});
}
return Promise.reject(error);
});
`
3. **Handle Repeated Failed Requests**: If a request fails repeatedly, it might be best to stop retrying after a certain number of attempts to avoid an infinite loop. You can do this by adding a retry counter to the request config:
javascript
axios.interceptors.response.use(undefined, error => {
if (error.config && error.response && error.response.status === 401) {
if (!error.config._retryCount) {
error.config._retryCount = 0;
}
if (error.config._retryCount >= 3) {
return Promise.reject(error);
}
error.config._retryCount++;
return refreshToken()
.then(_ => {
error.config.headers['Authorization'] = 'Bearer ' + localStorage.getItem('accessToken');
return axios(error.config);
});
}
return Promise.reject(error);
});
