Vite Vanilla JavaScript Simple App

This example demonstrates how to use the lunex-http library in a modern Vanilla JavaScript app scaffolded with Vite. It shows a minimal setup that runs in the browser with ES module support and leverages Vite’s fast development server.

How to run this example​

  • Run npm install (to install dependencies including lunex-http).
  • Run npm run dev to start the Vite dev server.
  • Open http://localhost:5173 (or the port shown in your terminal) in a modern browser.
Note

Vite automatically supports ES modules and hot module replacement, making it ideal for frontend development with libraries like lunex-http.

What this example shows​

  • How to import lunex-http directly in an ES module.
  • How to instantiate LunexClient with a base API URL.
  • How to make asynchronous requests with getAsync.
  • Basic DOM manipulation to show a simple greeting.
  • Console output of the fetched API response.

Notes​

  • Replace 'https://api.example.com/' in main.js with your actual API endpoint.
  • Vite requires Node.js and npm/yarn installed on your system.
  • This example assumes a simple user endpoint at users for demonstration.
