API

ruit

Serialize a list of sync and async tasks from left to right

Parameters

• tasks any list of tasks to process sequentially

const curry = f => a => b => f(a, b)
const add = (a, b) => a + b

const addOne = curry(add)(1)

const squareAsync = (num) => {
  return new Promise(r => {
    setTimeout(r, 500, num * 2)
  })
}

// a -> a + a -> a * 2
// basically from left to right: 1 => 1 + 1 => 2 * 2
ruit(1, addOne, squareAsync).then(result => console.log(result)) // 4

Returns Promise a promise containing the result of the whole chain

cancel

Helper that can be returned by ruit function to cancel the tasks chain

Examples

ruit(
  100,
  num => Math.random() * num
  num => num > 50 ? ruit.cancel() : num
  num => num - 2
).then(result => {
  console.log(result) // here we will get only number lower than 50
})

Returns Symbol internal private constant

compose

The same as ruit() but with the arguments inverted from right to left

Parameters

• tasks any list of tasks to process sequentially

Examples

const curry = f => a => b => f(a, b)
const add = (a, b) => a + b

const addOne = curry(add)(1)

const squareAsync = (num) => {
  return new Promise(r => {
    setTimeout(r, 500, num * 2)
  })
}

// a -> a + a -> a * 2
// basically from right to left: 1 => 1 + 1 => 2 * 2
ruit.compose(squareAsync, addOne, 1).then(result => console.log(result)) // 4

Returns Promise a promise containing the result of the whole chain
