Get the Status Code of an Axios HTTP Error in JavaScript

# Get the Status Code of an Axios HTTP Error

Use the status property on the error.response object to get the status code from an HTTP error response, e.g. error.response.status.

The status property on the error.response object returns the status code that was issued by the server in a response to the client's request.

index.js

import axios from 'axios';

async function makeRequest() {
  try {
    const res = await axios.get('https://example.com/does-not-exist');
    const data = res.data;
    console.log(data);
  } catch (err) {
    if (err.response) {
      // ✅ log status code here
      console.log(err.response.status);
      console.log(err.message);
      console.log(err.response.headers); // 👉️ {... response headers here}
      console.log(err.response.data); // 👉️ {... response data here}
    }
  }
}

makeRequest();

get status code of axios http error

In the example, we requested a route that isn't present on the example.com domain and got a 404 response back.

To get the status code of the error, we caught the error in a catch block and accessed the status property on the error.response object.

# Same example but using Promise.then()

Here is the same example if you are using promise.then() and promise.catch(), instead of async/await.

index.js

Copied!
import axios from 'axios';

function makeRequest() {
  axios
    .get('https://example.com/some-path')
    .then(res => {
      const data = res.data;
      console.log(data);
    })
    .catch(err => {
      if (err.response) {
        console.log(err.response.status);
        console.log(err.response.statusText);
        console.log(err.message);
        console.log(err.response.headers); // 👉️ {... response headers here}
        console.log(err.response.data); // 👉️ {... response data here}
      }
    });
}

makeRequest();

get status code of axios http error using then method

Notice that, we first check if the error.response object is populated.

This is necessary because we can only expect a status code from the server if the error occurred on the server.

If the error occurred when setting up the request or because the server didn't respond at all, the error.response object will not be populated.

Here is a more complete example of handling errors in axios.

import axios from 'axios';

async function makeRequest() {
  try {
    const res = await axios.get('https://example.com/does-not-exist');
    const data = res.data;
    console.log(data);
  } catch (err) {
    if (err.response) {
      // 👇️ log status code here
      console.log(err.response.status);
      console.log(err.response.statusText);
      console.log(err.message);
      console.log(err.response.headers); // 👉️ {... response headers here}
      console.log(err.response.data); // 👉️ {... response data here}
    } else if (error.request) {
      // 👇️ Request was made, but no response was received
      console.log(error.request);
    } else {
      // 👇️ An error was thrown when setting up the request
      console.log(error.message);
    }
  }
}

complete example of handling errors in axios

The majority of the HTTP errors you will get fall into the error.response categories of:

4xx client error (the request contains bad syntax or cannot be fulfilled)
5xx server error (the server failed to fulfill a valid request).

Either way, you should at least log the errors from the other categories to make your life easier when debugging if the error.response object is not populated.

I've also written an article on how to get the status code of a fetch HTTP response.
