Fetch API wrapped in a TaskEither.

Installation

yarn add @pacote/ffetch

Handling results

The returned Either can be handled with fp-ts mapping functions, keeping success and failure paths explicit:

import { ffetch } from '@pacote/ffetch'
import { pipe } from 'fp-ts/function'
import { map, mapLeft, getOrElse } from 'fp-ts/lib/Either'

const response = await ffetch('https://goblindegook.com/api/kittens/1')()

pipe(
  response,
  map((body) => {
    /* handle successful response */
    return body
  }),
  mapLeft((error) => {
    /* handle request failure */
    return error
  }),
)

const okOrDefault = pipe(
  response,
  getOrElse(() => 'some default value'),
)
Copy
