Using AI to Implement Error Handling in Client-Side Axios Requests

Using AI to Implement Error Handling in Client-Side Axios Requests blog article main image

A GPT-Assisted Approach


The use of AI models like GPT to add error handling to existing code offers a multitude of advantages:

  1. Improved Code Stability
    By adding error handling to code, AI can make the software more resilient to unexpected scenarios, enhancing its reliability and user experience.
  2. Increased Developer Productivity
    Writing comprehensive error handling can be time-consuming. By automating this task, AI allows developers to focus on core functionality and innovation.
  3. Consistent Error Handling
    AI can ensure consistency in the application of error handling practices across a codebase. This makes code easier to understand and maintain.
  4. Reduced Bugs and Downtime
    AI can identify potential pitfalls and edge cases that may have been overlooked by developers and add appropriate error handling, reducing the occurrence of bugs and system crashes.
  5. Enhanced Code Quality Automated error handling contributes to improved code quality, making the software more robust and maintainable.
  6. Predictive Error Detection
    AI can leverage patterns and scenarios from its training data to predict possible errors in your code that you may not have even considered.
  7. Reduced Maintenance Costs
    With comprehensive error handling, issues can be detected and addressed immediately, reducing the time and cost of troubleshooting and maintenance.
  8. Better User Experience
    By implementing proper error handling, programs can provide more informative error messages to users and prevent abrupt crashes, leading to a better user experience.

However, it's important to mention that AI's effectiveness at adding error handling to existing code largely depends on the quality of its training. Also, while AI can add basic error handling, there may be complex situations that require a human developer's expertise and understanding of the software's specific context and usage.

In this post, we'll add error handling to a client-side login function that uses the Axios library to make HTTP requests.

GPT Prompt

Add error handling to the following client side code:

import axios from 'axios';

const username = 'johndoe';
const password = 'password';

async function login() {
  const response = await'http://localhost:3000/api/auth/login', {

  const token = response.headers['authorization'];
  return token;

const token = await login();

Prompt Overview

The AI was asked to add error handling to a client-side code snippet which uses the Axios library for HTTP requests. The AI implemented error handling using try/catch blocks, and added checks for potential issues such as missing headers in the response.

GPT Response

Here's how we could add error handling to the function:

import axios from 'axios';

const username = 'johndoe';
const password = 'password';

async function login() {
  try {
    const response = await'http://localhost:3000/api/auth/login', {

    const token = response.headers['authorization'];

    if (!token) {
      throw new Error('Authorization token not found in response headers');

    return token;
  } catch (error) {
    console.error(`Failed to log in: ${error.message}`);
    return null;

  .then(token => {
    if (token) {
    } else {
      console.log('Login failed');

GPT Response Overview

  1. In the updated function, we've enclosed the axios call in a try block. This means if any error is thrown while executing the code inside this block, instead of crashing the program, it'll be caught and handled by the catch block.
  2. Inside the catch block, we log the error message to the console, and return null to signify that the login failed.
  3. We also added a check to ensure the authorization header is present in the response. If not, we throw an error.
  4. Finally, when calling the login function, we handle the returned promise. If the login is successful, we print the token. If not, we print a failure message.

Benefits and Conclusion

Adding error handling to your client-side code is crucial for building robust applications. It allows you to catch and handle errors gracefully, providing informative feedback to your users and making your application more resilient to unexpected situations.
