typescript - fp-ts - 不推荐使用管道

Question

我在我的 typescript/react 项目中使用 "fp-ts": "^2.10.5" 并且收到警告说“管道”已被弃用。以下代码来自this使用 fp-ts 进行错误处理和验证的教程:

import { Either, left, right } from 'fp-ts/lib/Either'
import { chain } from 'fp-ts/lib/Either'
import { pipe } from 'fp-ts/lib/pipeable'
//
const minLength = (s: string): Either<string, string> =>
  s.length >= 6 ? right(s) : left('at least 6 characters')

const oneCapital = (s: string): Either<string, string> =>
  /[A-Z]/g.test(s) ? right(s) : left('at least one capital letter')

const oneNumber = (s: string): Either<string, string> =>
  /[0-9]/g.test(s) ? right(s) : left('at least one number')


const validatePassword = (s: string): Either<string, string> =>
  pipe(
    minLength(s),
    chain(oneCapital),
    chain(oneNumber)
  )

changelog记录此弃用状态:

deprecate pipeable module, use the specific helpers instead

什么是“特定助手”？我该如何解决这个警告？

Answer 1

要解决此警告，请导入 pipe来自 fp-ts/lib/function而不是 fp-ts/lib/pipeable :

import { pipe } from 'fp-ts/lib/function'
