typescript.unbounded_retry

Stability High

Detects retry loops without maximum attempt limits.

Why It Matters

Unbounded retries:

Infinite loops — Never give up on permanent failures
Amplify load — Retry storms overwhelm upstream
Waste resources — CPU/network spent on hopeless retries

Example

// ❌ Before (unbounded retry)
async function fetchData(): Promise<Data> {
  while (true) {
    try {
      return await axios.get('/data');
    } catch {
      await sleep(1000);
    }
  }
}

// ✅ After (with max retries and backoff)
import retry from 'async-retry';

async function fetchData(): Promise<Data> {
  return retry(
    async () => {
      return axios.get('/data');
    },
    {
      retries: 3,
      factor: 2,
      minTimeout: 1000,
      maxTimeout: 10000,
    }
  );
}

What Unfault Detects

While(true) retry loops
Missing max retry count
No exponential backoff

Auto-Fix

Unfault can add retry limits using async-retry.
