to-array

consume an iterable and return an array of all items.

Usage

package requires a system that supports async-iteration, either natively or via down-compiling

Install

npm install @async-generators/to-array --save
yarn add @async-generators/to-array

This package's main entry points to a commonjs distribution.

Additionally, the module entry points to a es2015 distribution, which can be used by build systems, such as webpack, to directly use es2015 modules.

Api

toArray(source)

toArray() iterates source, adds each item to an array and returns the array when the source() iterator completes.

Example

example.js

const toArray = require('@async-generators/to-array').default;

async function main() {

  let source = async function* () {   
    yield 1; yield 2; yield 3; yield 4;
  }

  let result = await toArray(source());

  console.log(result);
}

main();

Execute with the latest node.js:

node --harmony-async-iteration example.js

output:

[ 1, 2, 3, 4 ]

Typescript

This library is fully typed and can be imported using:

import toArray from '@async-generators/to-array');

It is also possible to directly execute your properly configured typescript with ts-node:

ts-node --harmony_async_iteration example.ts
