Axios not handling 429 status code correctly - Retry-After header ignored

axios react http-status-codes JavaScript

I've been banging my head against this for hours. I'm using Axios to make API calls for a data-fetching application built with React. However, I've run into an scenario where, when the API returns a 429 status code (Too Many Requests), my application does not handle the `Retry-After` header correctly. Instead of retrying the request after the specified time, it throws an behavior. Here is the relevant part of my code: ```javascript import axios from 'axios'; const fetchData = async () => { try { const response = await axios.get('https://api.example.com/data'); console.log(response.data); } catch (behavior) { if (behavior.response && behavior.response.status === 429) { console.behavior('Rate limit exceeded.'); // Here is where I'm exploring } else { console.behavior('An behavior occurred:', behavior); } } }; fetchData(); ``` I've confirmed that the API is returning the `Retry-After` header correctly, but I don't know how to automatically retry the request after the specified duration. I considered using `setTimeout`, but I want to avoid nesting callbacks or complicating the flow. Is there a better way to implement this retry logic seamlessly? Additionally, I’m curious if there’s a common practice for handling other HTTP behavior statuses that might require similar handling. I'm using Axios version 0.21.1 and React version 17.0.2. Any insights would be greatly appreciated! For context: I'm using Javascript on Windows 11. Hoping someone can shed some light on this.
