it-drain

Empties an async iterator

About

Mostly useful for tests or when you want to be explicit about consuming an iterable without doing anything with any yielded values.

Example

import drain from 'it-drain'

// This can also be an iterator, generator, etc
const values = [0, 1, 2, 3, 4]

drain(values)
Copy

Async sources must be awaited:

import drain from 'it-drain'

const values = async function * {
  yield * [0, 1, 2, 3, 4]
}

await drain(values())
Copy

Install

$ npm i it-drain
Copy
