Package Exports

cached-iterable
cached-iterable/compat

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (cached-iterable) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

cached-iterable

cached-iterable exposes two classes which implement the iterable protocol:

CachedSyncIterable,
CachedAsyncIterable.

You can wrap any iterable in these classes to create a new iterable which caches the yielded elements. This is useful for iterating over an iterable many times without depleting it.

Installation

cached-iterable can be used both on the client-side and the server-side. You can install it from the npm registry or use it as a standalone script (as the CachedIterable global).

npm install cached-iterable

How to use

import assert from "assert";
import {CachedSyncIterable} from "cached-iterable";

function * countdown(i) {
    while (i--) {
        yield i;
    }
}

let numbers = new CachedSyncIterable(countdown(3));

// `numbers` can be iterated over multiple times.
assert.deepEqual([...numbers], [3, 2, 1, 0]);
assert.deepEqual([...numbers], [3, 2, 1, 0]);

Compatibility

For legacy browsers, the compat build has been transpiled using Babel's env preset. It requires the regenerator runtime provided by babel-polyfill.

import {CachedSyncIterable} from 'cached-iterable/compat';
