Package: effect
Module: SchemaTransformation

SchemaTransformation.durationFromString

Decodes a string into a Duration and encodes a Duration back to a parseable string.

When to use

Use when you need a schema transformation to parse human-readable duration strings from APIs, config, or user input.

Details

Decoding accepts any string that Duration.fromInput can parse, including "Infinity" and "-Infinity". Encoding returns String(duration), producing strings such as "2000 millis" or "10 nanos" that round-trip through the parser.

Example (Converting a string to a Duration)

import { Schema, SchemaTransformation } from "effect"

const schema = Schema.String.pipe(
  Schema.decodeTo(Schema.Duration, SchemaTransformation.durationFromString)
)
