JSPM – react-measure@0.1.0

Package Exports

react-measure

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (react-measure) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

React Measure 0.1.0

Compute measurements of React components.

Install

npm install react-measure --save

bower install react-measure --save

Example Usage using ES6 & Babel Stage 0

import Measure from 'react-measure';

class ItemToMeasure extends Component {
  state = {
    measurements: {}
  }

  render() {
    const { width, height, top, right, bottom, left } = this.state.dimensions;

    return(
      <Measure
        whitelist={['width', 'height']}
        blacklist={['top', 'left']}
        onChange={m => this.setState({measurements: m})}
      >
        <div>
          I can do cool things with my measurements now :D
        </div>
      </Measure>
    )
  }
}

Good to knows

To help avoid layout thrashing, use the prop blacklist to ignore specific values and stop firing a render to check the DOM for changes. Likewise you can use whitelist to choose only the ones you need to check.

CHANGELOG

0.0.1

Rewritten to be more React friendly

Measure component no longer accepts a child function, instead get dimensions by setting state in onChange callback
