Vue HTTP Requests with Axios — Complete Guide

In this tutorial, you will learn about Vue HTTP Requests with Axios. We cover key concepts, practical examples, and best practices to help you master this topic.

Axios is the most popular HTTP client for Vue applications, providing request/response interceptors, automatic JSON Parsing, request cancellation, and progress events.

What You'll Learn

• Installing and configuring Axios
• Making GET, POST, PUT, DELETE requests
• Using interceptors for auth tokens
• Cancelling requests
• Error handling patterns

Why It Matters

Axios simplifies HTTP communication with features that fetch lacks: automatic JSON transformation, request timeouts, interceptors, and upload progress events.

// services/api.js
import axios from "axios";

const api = axios.create({
  baseURL: "https://api.example.com",
  timeout: 10000,
});

api.interceptors.request.use((config) => {
  const token = localStorage.getItem("token");
  if (token) config.headers.Authorization = `Bearer ${token}`;
  return config;
});

api.interceptors.response.use(
  (response) => response,
  (error) => {
    if (error.response?.status === 401) {
      localStorage.removeItem("token");
      window.location.href = "/login";
    }
    return Promise.reject(error);
  }
);

export default api;

Expected output: An Axios instance with auth interceptor that attaches tokens and redirects on 401 errors.
