React Body Images

A way to add one background image to body, or create body background slider in a single-page app. Based on Iestyn William's project react-body-className. So, you can manipulate your body's className too

This component can be use the className feature on server side as well.

Built with React Side Effect.

====================

Installation

npm install --save react-body-images

Dependencies: React >= 0.13.0

Features

• Does not emit DOM, not even a <noscript>;
• Like a normal React compoment, can use its parent's props and state;
• Can be defined in many places throughout the application;
• Supports arbitrary levels of nesting, combining each className;
• Works just as well with isomorphic apps.

Example

class SomeComponent {
  render() {
    // This will add an array of background images to the body
	// And add className 'home' too
	// You should put the path to the image in the array.
	// var images = ["/img/image1.jpg","/img/image2.jpg"];
	// If this is a nested component you can specify if you want to show the background images or not using removeBackgroundImages property.
	// If removeBackgroundImages is true in a nested component, the background images are the specified by the main Component.
    return (
      <BodyImages className='home' bgImageArray={this.state.images} transitionSeconds={15} removeBackgroundImages{true/false}>
        <h1>Hogar, dulce hogar.</h1>
      </BodyImages>
    );
  }
}

class App {
  render() {
    // This will add an array of background images to the body
	// And add className 'app' too
	// You should put the path to the image in the array.
	// var images = ["/img/image1.jpg","/img/image2.jpg"];
	// If you want to see in the console debug comments you can specify that using inDebugMode property.
    return (
      <BodyImages className='app' bgImageArray={this.state.images} transitionSeconds={15} inDebugMode={true}>
        <SomeComponent/>
      </BodyImages>
    );
    // Becuase we nested the component, our body will now replace the background images especified in SomeComponent and have the 'app home' as the class name
  }
}

Use CSS modules with webpack or similar?

import styles from './some.css';

class Thing {
  render() {
	// You should put the path to the image in the array.
	// var images = ["/img/image1.jpg","/img/image2.jpg"];
    return (
	  <BodyImages className={styles.body} bgImageArray={this.state.images} transitionSeconds={15}>
        <h1>CSS modules rock!</h1>
      </BodyImages>
    );
  }
}

If you need to remove the background:

import styles from './some.css';

class Thing {
  render() {
    return (
	  <BodyImages className={styles.body} removeBackgroundImages={true}>
        <h1>CSS modules rock!</h1>
      </BodyImages>
    );
  }
}

Server Usage

If you use it on server the className feature , call BodyClassName.rewind() after rendering components to string to retrieve the combined class name. You can then embed this className into HTML page template.

Because this component keeps track of mounted instances, you have to make sure to call rewind on server, or you'll get a memory leak.
