# React Preload

[![npm version](https://badge.fury.io/js/react-preload.svg)](http://badge.fury.io/js/react-preload)

A React component to preload images. It renders a passed component during the loader phase, and renders its children once the images have been successfully fetched.

## Installation

### npm

```bash

npm install react-preload --save

```

## Usage

```javascript

var Preload = require('react-preload').Preload;

```

```javascript

var loadingIndicator = (
Loading...
);

var images = [];


    {/* content to be rendered once loading is complete */}

```

## Prop types

```javascript

propTypes: {

    // Rendered on success

    children: PropTypes.element.isRequired,

    // Rendered during load

    loadingIndicator: PropTypes.node.isRequired, // Default: null

    // Array of image urls to be preloaded

    images: PropTypes.array, // Default: []

    // If set, the preloader will automatically show

    // the children content after this amount of time

    autoResolveDelay: PropTypes.number,

    // Error callback. Is passed the error

    onError: PropTypes.func,

    // Success callback

    onSuccess: PropTypes.func,

    // Whether or not we should still show the content

    // even if there is a preloading error

    resolveOnError: PropTypes.bool, // Default: true

    // Whether or not we should mount the child content after

    // images have finished loading (or after autoResolveDelay)

    mountChildren: PropTypes.bool, // Default: true

}

```

## Additional Details

This module also exposes `ImageCache` and `ImageHelper` which can be used to preload images

directly, and can be accessed via `require('react-preload').ImageCache` and

`require('react-preload').ImageHelper` respectively.
