Effect Units of Measure

Typesafe units for Effect.

Usage

Example:

import * as uom from "effect-uom";

const width = uom.Meter(5);
const height = uom.Meter(3);
const area = uom.mul(width, height);
// `area` will be of type `Square<Meter>` which is equivalent to `Unit<{ Meter: 2 }>`.

useArea(area);
useVolume(area); // type error - `Square<Meter>` is not assignable to `Cubic<Length>`.

function useArea<A extends uom.Square<uom.Length>>(area: A) {
  // ...
}

function useVolume<V extends uom.Cubic<uom.Length>>(volume: V) {
  // ...
}
Copy

UOM Types

This library uses uom-types as its base and re-exports everything from it. See the uom-types docs for more information.
