Fly V3 Script May 2026

Run the script using:

Fly V3 scripts operate in hostile environments (network flaps, API throttling). Implement exponential backoff natively: fly v3 script

flyv3 run monitor.fly.js --watch To move beyond basic scripting, you must leverage the advanced features of Fly V3. Parallel Execution Maps Unlike standard for loops, Fly V3 supports parallel maps that respect system limits. Run the script using: Fly V3 scripts operate

if (!cache.has("jwt_token") || cache.get("jwt_expires") < Date.now()) const freshToken = await authenticate(); cache.set("jwt_token", freshToken, 3600); // TTL 1 hour if (!cache.has("jwt_token") || cache.get("jwt_expires") &lt

async function resilientCall(fn, retries = 5) for (let i = 0; i < retries; i++) try return await fn(); catch (err) if (i === retries - 1) throw err; const delay = Math.pow(2, i) * 1000; await Fly.sleep(delay);

flyctl install --version 3.x Create a new script file: monitor.fly.js // monitor.fly.js // Fly V3 Script - Health Monitor version = "3.0" runtime = "async" interval = "30s" // Runs every 30 seconds

// Example Fly V3 Init const config = endpoint: "https://api.flyv3.example", retries: 3, timeout: 5000 ; let session = null; The heart of the script. Fly V3 is reactive; it waits for triggers (time-based, HTTP, or socket events). The handler processes these triggers.
