Using Fetch vs Axios

🔍 Fetch vs Axios in React

When it comes to making HTTP requests in React, two of the most popular choices are the built-in fetch API and the third-party library axios. Both can handle data fetching, but they differ in syntax, features, and developer experience. ⚔️

🧱 What is Fetch?

fetch() is a native web API supported by all modern browsers. It’s simple, flexible, and doesn’t require installation.

fetch("https://api.example.com/data")
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error("Error:", error));

📦 What is Axios?

Axios is a promise-based HTTP client for the browser and Node.js. It offers a cleaner syntax and additional features out-of-the-box.

import axios from "axios";

axios.get("https://api.example.com/data")
  .then(response => console.log(response.data))
  .catch(error => console.error("Error:", error));

📊 Feature Comparison Table

🎯 When to Use Fetch

Fetch is ideal when:

• ✅ You want zero dependencies
• ✅ You only need basic GET/POST requests
• ✅ You want full control of request lifecycle

🚀 When to Use Axios

Axios shines when:

• ✅ You need request/response interceptors
• ✅ You want automatic JSON parsing
• ✅ You need to easily handle timeouts or errors
• ✅ You're uploading files or handling form data

🔁 Handling POST Requests

✅ With Fetch

fetch("https://api.example.com/data", {
  method: "POST",
  headers: {
    "Content-Type": "application/json"
  },
  body: JSON.stringify({ name: "John" })
})
.then(res => res.json())
.then(data => console.log(data));

✅ With Axios

axios.post("https://api.example.com/data", {
  name: "John"
})
.then(response => console.log(response.data));

⚠️ Error Handling Comparison

❌ Fetch

Needs manual response.ok check:

fetch("/data")
  .then(res => {
    if (!res.ok) throw new Error("Failed");
    return res.json();
  })
  .catch(err => console.error(err));

✅ Axios

Throws automatically for bad status codes:

axios.get("/data")
  .then(res => console.log(res.data))
  .catch(err => console.error(err.message));

🧠 Developer Experience

If you prefer minimalism, go with Fetch. But for convenience, retries, interceptors, and advanced use cases, Axios can save a lot of boilerplate.

📋 Summary

• ⚙️ Fetch is built-in, lightweight, but requires more setup for common tasks
• 🧰 Axios is feature-rich and easier for complex requests
• ✅ Use what best suits your project scale and needs

🚀 Final Thoughts

Both Fetch and Axios are excellent tools for making HTTP requests in React. If you're building a lightweight app or learning the fundamentals, start with Fetch. For scalable apps with multiple API interactions, Axios may improve code maintainability and reduce complexity. ⚖️🔌
