FixedDelay

FixedDelay retries using a constant interval until max attempts is reached.

Import

import { FixedDelay } from "@zap-studio/retry/fixed-delay";

Configuration

const policy = new FixedDelay({
  maxAttempts: 4,
  delayMs: 300,
});

Behavior

• Every retry uses the same delayMs
• Stops when attempt >= maxAttempts
• Returns a terminal decision with reason: "max-attempts-reached"

When to Use

Use FixedDelay when:

• your backend has predictable recovery windows
• you want straightforward retry timing
• you need easy-to-debug behavior in tests

Example

const policy = new FixedDelay({
  maxAttempts: 3,
  delayMs: 250,
});

const value = await policy.run(async () => {
  return await readFromCacheOrApi();
});
