Adpanel

An advert panel using GPT tags

Usage

This component expects an ES6 environment, and so if you are using this in an app, you should drop in a polyfill library - it has been tested with babel-polyfill but core-js or es6-shim may also work.

The default export is a React Component, so you can simply import the component and use it within some JSX, like so:

import Adpanel from '@economist/component-ad-panel';

return <Adpanel/>;

For more examples on usage, see src/example.es6.

Props and defaults:

• adTag (required string): The DFP tag this points to. Often in the format of a URL. example: /5605/foo.bar/qux/x.
• className (string): Add this className to ad-panel__container.

sizes={[ [ 60, 60 ], [ 70, 70 ], [ 300, 250 ], [ 1024, 768 ] ]} ``` (array of pairs of advertisement width, height): what ad sizes can be loaded. Is used as the size argument to googletag.defineSlot

sizeMapping={[ [[980, 200], [[1024, 768]]], [[0, 0], [[300, 250]]], ]} ``` (array of pairs of screen sizes [ width, height ] and advertisement sizes [ [width1, height1], [width2, height2], ... ] ): Each element in this array results in a call to sizeMapping().addSize

• targeting (array of pairs of key/value strings): Defines the ad targeting. Each element corresponds to a call to setTargeting
• reserveHeight (number of px): Sets a min-height to the ad, so as to avoid content jumps when the ad eventually comes around.
• googletag (instance of the googletag object): Mostly a testing hook, but can be passed to avoid loading the DFP tag again, if it was already loaded.

Relevant reading:

• The window.googletag API
• understanding sizeMappings

Deprecation notice

The lazyload prop has been removed as the feature was making this component unmaintainable and bug-prone. From now on you can use the excellent react-lazy-load. Here's an example:

// Before:
<AdPanel lazyLoad {...otherProps} />

// After:
<LazyLoad>
  <AdPanel {...otherProps} />
</LazyLoad>

The animated prop has also been removed, and its relevant CSS with it. This feature can also be implemented very easily using LazyLoad (and some classNames):

// Before:
<AdPanel animated {...otherProps} />

// After:
class AnimatedAd extends React.Component {
  render() {
    const className = this.state && this.state.visible ?
      'animated-ad-wrapper animated-ad-wrapper--visible' :
      'animated-ad-wrapper';
    return (
      <div className={className}>
        <LazyLoad onContentVisible={() => { this.setState({ visible: true }) }}>
          <AdPanel {...this.props} />
        </LazyLoad>
      </div>
    )
  }
}
<AnimatedAd {...otherProps} />

Both work exactly the same.
