Description: React component to wrap your application or component in an iFrame for encapsulation purposes
Author: Ryan Seddon
Latest version: 2.0.5

# React &lt;Frame /> component

[![NPM version][npm-image]][npm-url] [![Build Status][travis-image]][travis-url] [![Dependency Status][depstat-image]][depstat-url]

This component allows you to encapsulate your entire React application or per component in an iFrame.

```bash
npm install --save react-frame-component
```

## How to use:

```js
import Frame from 'react-frame-component';
```

Go check out the [demo][demo-url].

```html
const Header = ({ children }) => (
  <Frame>
    <h1>{children}</h1>
  </Frame>
);

ReactDOM.render(<Header>Hello</Header>, document.body);
```

Or you can wrap it at the `render` call.

```html
ReactDOM.render(
  <Frame>
    <Header>Hello</Header>
  </Frame>,
  document.body
);
```

##### Props:

###### head
`head:  PropTypes.node`

The `head` prop is a dom node that gets inserted before the children of the frame. Note that this is injected into the body of frame (see the blog post for why). This has the benefit of being able to update and works for stylesheets.

###### initialContent
`initialContent:  PropTypes.string`

Defaults to `'<!DOCTYPE html><html><head></head><body><div></div></body></html>'`

The `initialContent` props is the initial html injected into frame. It is only injected once, but allows you to insert any html into the frame (e.g. a head tag, script tags, etc). Note that it does *not* update if you change the prop. Also at least one div is required in the body of the html, which we use to render the react dom into.

###### mountTarget
`mountTarget:  PropTypes.string`

The `mountTarget` props is a css selector (#target/.target) that specifies where in the `initialContent` of the iframe, children will be mounted.

```html
<Frame
  initialContent='<!DOCTYPE html><html><head></head><body><h1>i wont be changed</h1><div id="mountHere"></div></body></html>'
  mountTarget='#mountHere'
  >
</Frame>
```

###### contentDidMount and contentDidUpdate
`contentDidMount:  PropTypes.func`
`contentDidUpdate:  PropTypes.func`

`contentDidMount` and `contentDidUpdate` are conceptually equivalent to
`componentDidMount` and `componentDidUpdate`, respecitvely. The reason these are
needed is because internally we call `ReactDOM.render` which starts a new set of
lifecycle calls. This set of lifecycle calls are sometimes triggered after the
lifecycle of the parent component, so these callbacks provide a hook to know
when the frame contents are mounted and updated.

###### Accessing the iframe's window and document
The iframe's `window` and `document` may be accessed via the React context values `window` and `document` respectively.

```js
const MyComponent = (props, context) => {
  const {
    document: iframeDocument,
    window: iframeWindow
  } = context;

  return (<...rendered jsx.../>);
};

MyComponent.contextTypes = {
  window: PropTypes.any,
  document: PropTypes.any
};
```
