Overview

MeasureThat.net is a website that allows users to create and run JavaScript microbenchmarks. In this case, we have two individual test cases comparing the performance of axios and fetch libraries in making HTTP requests.

Benchmark Definition

The benchmark definition consists of a script preparation code and an HTML preparation code. The script preparation code is empty, which means that the user needs to provide their own script for each test case. However, in this example, the provided scripts are:

• For axios: const url = "https://jsonplaceholder.typicode.com/todos"; axios.get(url).then((response) => console.log(response.data));
• For fetch: const url = "https://jsonplaceholder.typicode.com/todos"; fetch(url) .then((response) => response.json()) .then((data) => console.log(data));

These scripts make a GET request to the same JSONPlaceholder API endpoint, but using different libraries.

Options Compared

The two options being compared are:

1. axios: A popular JavaScript library for making HTTP requests.
2. fetch: A built-in JavaScript API for making HTTP requests.

Pros and Cons of Each Approach

• axios:
  • Pros:
    • More feature-rich than fetch, with support for things like HTTP headers, query parameters, and caching.
    • Can be more convenient to use, especially for complex requests or when dealing with errors.
  • Cons:
    • Adds an extra dependency to the project, which can increase bundle size.
    • May not perform as well as fetch in certain scenarios (e.g., when dealing with large payloads).
• fetch:
  • Pros:
    • Built-in to modern browsers, so no additional library needs to be included.
    • Can be more lightweight than axios, especially for simple requests.
  • Cons:
    • Less feature-rich than axios, requiring more manual setup and error handling.
    • May not support all the advanced features of axios.

Library: Axios

Axios is a popular JavaScript library for making HTTP requests. It provides a simple and intuitive API for sending HTTP requests, with features like:

• Support for HTTP headers
• Query parameters
• Caching
• Error handling

The purpose of using axios in this benchmark is to compare its performance against the built-in fetch API.

Special JS Feature: Fetch

The fetch API is a built-in JavaScript feature that allows making HTTP requests. It provides a simple and modern way of sending HTTP requests, with features like:

• Automatic handling of promises
• Support for HTTP headers and query parameters

The purpose of using fetch in this benchmark is to compare its performance against the external library axios.

Other Alternatives

If you're looking for alternative libraries or APIs for making HTTP requests, some options include:

• jQuery.ajax(): A part of the jQuery library, which provides a way of sending HTTP requests with features like caching and error handling.
• XMLHttpRequest: A built-in JavaScript API for making HTTP requests, but less feature-rich than fetch or axios.
• node-http: A lightweight HTTP client library for Node.js, which can be used to make HTTP requests.

Overall, the choice of using axios or fetch (or another library) depends on your specific use case and performance requirements.
