TYPE PIPE

type-pipe contains a type-safe pipe() function implementation, because you just can't wait for JS-native pipes.

// begin with a value
const result = pipe(() => "2")
  // it is passed as the first argument to the next piped function
  .pipe(parseInt)
  // you may pass additional arguments, beyond the first piped argument
  .pipe(add, 2)
  // your functions must expect the same type as the prior function
  .pipe((num: number) => num.toString())
  // as your value changes, so does the required type of your piped functions
  .pipe((num: string) => num.repeat(3))

const add = (num1: number, num2: number) => num1 + num2

• ⛓ Chaining functions via pipe().pipe() etc.
• 🏭 Passing the return of one pipe to the first argument of the next pipe
• 👾 Catching errors and returning them safely
• 🦺 Type safety between pipes
