Node-Cycle

High Precision Adaptive Timer for Node.js

Tip

How to bypass event loop delays?
The loop itself bypasses and takes into account event loop delays, but I highly recommend using custom.step and dynamically changing the loop time there.

🧪 Tested For

• ✅ Discord UDP/RTP VoIP streams
• ✅ Real-world drift: ~0.05ms
• ✅ FFmpeg filter loops (EQ, tempo, pitch, etc.)

---

🚀 Features

• 📏 Sub-millisecond drift correction using performance.now() + Date.now
• 🔁 Stable timing even under event loop pressure
• 🎯 Self-correcting loop with zero-delay recovery
• 🧠 No native bindings, 100% JavaScript
• ♻️ Auto garbage collection after cycle completes
• 🧩 Extremely modular — plug into your own system (TaskCycle)

How to use

import { TaskCycle } from 'snpk-cycle';

const cycles = new class LowerCycle<T extends any> extends TaskCycle<T> {
    public constructor() {
        super({
            // Time until next cycle run
            duration: 20,
            
            // If dot not need drifting in cycle
            drift: false,
            
            // Custom functions (if you want to change the execution logic a little)
            custom: {},

            // Check function
            filter: (item: T) => true,

            // Execution of the function after the specified time, taking into account the filter
            execute: (item: T) => {
                // Your code
            }
        });
    };
};

// Adding your object
cycles.add(item);
