Congratulations! Your 3D web experience is live and accessible to the world. But the journey doesn't end at deployment. To ensure your creation remains performant, engaging, and bug-free, continuous monitoring and iteration are crucial. This section will guide you through the essential practices for post-deployment success with your Three.js projects.
- Performance Monitoring: The First Line of Defense
Even after optimization during development, real-world performance can vary due to different user devices, network conditions, and browser versions. Tracking key performance indicators (KPIs) will help you identify and address bottlenecks.
Key metrics to monitor include:
- Frame Rate (FPS): This is the most direct indicator of your application's smoothness. Dropping below 60 FPS can lead to a noticeable lag and a poor user experience.
- Loading Times: How long does it take for your scene to become interactive? This includes asset loading (models, textures, audio) and JavaScript execution.
- Memory Usage: Excessive memory consumption can lead to browser crashes or slow down other applications on the user's device.
- CPU Usage: High CPU usage can indicate inefficient algorithms or rendering processes.
import * as THREE from 'three';
const clock = new THREE.Clock();
let lastFrameTime = 0;
function animate() {
requestAnimationFrame(animate);
const deltaTime = clock.getDelta(); // Time since last frame in seconds
const currentTime = clock.getElapsedTime();
// Calculate FPS
const fps = 1000 / ((currentTime - lastFrameTime) * 1000);
lastFrameTime = currentTime;
// You can now log or send this FPS data to a monitoring service
// console.log(`FPS: ${fps.toFixed(2)}`);
// ... your rendering logic here ...
}
