## How to Use

`npm install react-image-timeline --save`

```js
import React from 'react';
import ReactDOM from 'react-dom';
import Timeline from 'react-image-timeline';
require('react-image-timeline/dist/timeline.css'); // .scss also available

const events = [
    {
        date: new Date(2013, 9, 27),
        text: "Sed leo elit, pellentesque sit amet congue quis, ornare nec lorem.",
        title: "Cairo, Egypt",
        buttonText: 'Click Me',
        imageUrl: "http://github.com/aaron9000/react-image-timeline/blob/master/src/assets/cairo.jpg?raw=true",
        onClick: console.log,
    }
];

ReactDOM.render(<Timeline events={events} />, document.getElementById('root'));
```

## Customization

#### Custom Styles
To customize the timeline, add your own CSS to override the [default styles](https://github.com/aaron9000/react-image-timeline/blob/master/src/lib/timeline.scss/).

#### Event Metadata
To pass extra data into custom components, use `extras` on `TimelineEvent`.

#### Custom Dot Pattern
The dots are defined in CSS using a [base64-encoded image](https://www.base64-image.de/). Encode a new image and override the corresponding CSS class.

#### Custom Components
For more advanced customization, you can pass in custom components to replace the defaults. Custom components will be passed a `TimelineEvent` model in props.
```js

const CustomHeader = (props) => {

    const {title, extras} = props.event;
    const {customField} = extras;

    return <div className="custom-header">
        <h1>{title}</h1>
        <p>{customField}</p>
    </div>;
};

ReactDOM.render(<Timeline events={events} customComponents={{header: CustomHeader}}/>, document.getElementById('root'));
```
