promiseChain

Chain async functions together

Usage

Creates a function that executes multiple functions in the same order as they are passed in arguments. Each function may be synchronous or asynchronous. The result of each function is passed to the next function. The final result is returned as a Promise.

import * as 
import _
_ from 'radashi'

const 
const func1: (a: number, b: number) => number
func1 = (
a: number
a: number, 
b: number
b: number) => 
a: number
a + 
b: number
b
const 
const func2: (n: number) => Promise<number>
func2 = async (
n: number
n: number) => 
n: number
n * 2
const 
const func3: (n: number) => Promise<string>
func3 = async (
n: number
n: number) => `Your Value is ${
n: number
n}`

const 
const chained: (a: number, b: number) => Promise<string>
chained = 
import _

function promiseChain<[a: number, b: number], number, number, string>(f1: (a: number, b: number) => _.Awaitable<number>, f2: (arg: number) => _.Awaitable<number>, f3: (arg: number) => _.Awaitable<string>): (a: number, b: number) => Promise<...> (+8 overloads)
Creates a function that executes multiple functions in the same
order as they are passed in arguments. Each function may be
synchronous or asynchronous. The result of each function is passed
to the next function. The final result is returned as a Promise.

@example 
const chained = promiseChain(
  (x: number, y: number) => x + y
  async (n: number) => n * 2
  async (n: number) => `Your Value is ${n}`
)

await chained(2, 3) // "Your Value is 10"

func3)

await
