Adaptive Loading Microsite

Differentially deliver fast, lighter experiences for users on slow networks & devices

A comprehensive showcase of adaptive loading strategies for modern web applications. This microsite demonstrates how to deliver optimized experiences based on user device capabilities, network conditions, and hardware constraints.

🚀 Features

Adaptive Loading Techniques

• Network-aware loading - Optimize content based on connection speed
• Memory-considerate loading - Adapt to device memory constraints
• Battery-aware loading - Respect user's battery preferences
• Hardware concurrency optimization - Scale based on CPU cores
• Save Data API integration - Honor data saver preferences
• Device class awareness - Target specific device capabilities

Framework Support

• React - Complete React Hooks library for adaptive loading
• Next.js - Server-side rendering with adaptive strategies
• Node.js - Backend adaptive serving examples
• Create React App - Client-side adaptive loading patterns

🛠 React Adaptive Hooks

This project includes a comprehensive React Hooks library for adaptive loading:

npm install react-adaptive-hooks

Available Hooks

import { useNetworkStatus } from 'react-adaptive-hooks/network';
import { useSaveData } from 'react-adaptive-hooks/save-data';
import { useHardwareConcurrency } from 'react-adaptive-hooks/hardware-concurrency';
import { useMemoryStatus } from 'react-adaptive-hooks/memory';

Quick Example

import React from 'react';
import { useNetworkStatus } from 'react-adaptive-hooks/network';

const AdaptiveComponent = () => {
  const { effectiveConnectionType } = useNetworkStatus();
  
  return (
    <div>
      {effectiveConnectionType === '4g' ? (
        <video controls>High-quality video</video>
      ) : (
        <img src="optimized-image.jpg" alt="Lightweight content" />
      )}
    </div>
  );
};
