Errors - axios 1.21.0 API reference

A failed request rejects with an AxiosError. It extends the native Error and adds code, config, request and response.

import axios, { AxiosError } from "axios";

try {
  await axios.get("https://api.example.com/nope");
} catch (err) {
  const e = err as AxiosError;
  if (e.response) {
    console.error(e.response.status, e.response.data);
  } else if (e.request) {
    console.error("no response", e.code);
  }
}
