@inato/effect-fpts-interop

Helper functions to interoperate between the Effect type and the ReaderTaskEither type.

!NOTE This repository acts as supporting document for this article that describe how at Inato we successfully migrated to Effect.

Installation

You can install this package via pnpm:

pnpm install @inato/effect-fpts-interop

Usage

portToEffect

import {
  getFptsMapping,
  portToEffect,
  type FptsAccess,
  type FptsConvertible,
} from "@inato/effect-fpts-interop";

interface MeasureString extends FptsConvertible<"measureString"> {
  measure: (value: string) => ReaderTaskEither<unknown, Error, number>
}

interface MeasureStringAccess extends FptsAccess<MeasureString> { }

declare const MeasureStringFpts: {
  measure: (value: string) => ReaderTaskEither<MeasureString, Error, number>
}

const Tag = Context.GenericTag<MeasureString>("MeasureString")

const MeasureString = portToEffect(
  MeasureStringFpts, 
  getFptsMapping(Tag, "measureString")
)

MeasureString.measure("hello 👋") // Effect<number, Error, MeasureString>

portToFpts

import {
  getFptsMapping,
  portToFpts,
  type FptsAccess,
  type FptsConvertible,
} from "@inato/effect-fpts-interop";

interface MeasureString extends FptsConvertible<"measureString"> {
  measure: (value: string) => Effect<number, Error>
}

interface MeasureStringAccess extends FptsAccess<MeasureString> { }

declare const MeasureStringFpts: {
  measure: (value: string) => ReaderTaskEither<MeasureString, Error, number>
}

const Tag = Context.GenericTag<MeasureString>("MeasureString")

const MeasureString = Effect.serviceFunctions(Tag)

const MeasureStringFpts = portToFpts(
  MeasureString, 
  getFptsMapping(Tag, "measureString")
)

MeasureStringFpts.measure("hello 👋") // ReaderTaskEither<MeasureStringAccess, Error, number>
