Response Interceptors in JavaScript
From the Axios cheat sheet · Interceptors & Error Handling · verified Jul 2026
Response Interceptors
Transform responses and handle errors globally
javascript
// Add response interceptor
axios.interceptors.response.use(
(response) => {
// Transform successful response
console.log('Response:', response.status);
return response.data; // Return only data
},
(error) => {
// Handle error globally
if (error.response?.status === 401) {
// Redirect to login
window.location.href = '/login';
}
return Promise.reject(error);
}
);✅ Centralize error handling - no try/catch in every component
💡 Implement token refresh logic to handle expired sessions
🔍 Return response to continue, reject to trigger catch block
⚡ Use _retry flag to prevent infinite retry loops
