repetitions - API reference

API reference › @evolu/common › Schedule › repetitions

function repetitions<Output, Input>(
  schedule: Schedule<Output, Input>,
): Schedule<number, Input>;

Defined in: packages/common/src/Schedule.ts:1570

Wraps a schedule to output the number of repetitions instead of original output.

Outputs 0, 1, 2, ... while preserving the underlying schedule's timing and termination behavior.

Counting repetitions

import {
  assertOk,
  exponential,
  repetitions,
  testCreateDeps,
} from "@evolu/common";

// Count retries while preserving exponential timing.
const step = repetitions(exponential("100ms"))(testCreateDeps());
assertOk(step(undefined), [0, 100]);
assertOk(step(undefined), [1, 200]);
