npm install react-heatmapA very simple port of heatmap.js for React. The idea behind this component is to be able to display a heatmap over any type of content (image, div, components ...). By default, the heatmap will always take all available width and height of its container.
Live demo: JonathanWi.github.io/react-heatmap
To build the examples locally, run:
``
npm install
npm start
Then open localhost:8000 in a browser.
The easiest way to use react-heatmap is to install it from NPM and include it in your own React build process (using Browserify, Webpack, etc).
You can also use the standalone build by including dist/react-heatmap.js in your page. If you use this, make sure you have already included React, and it is available as a global variable.
`
npm install react-heatmap --save
This component is pretty straightforward and only expecting 2 simple parameters (max and data; if you're unfamiliar with these, take a look at the heatmap.js documentation);
`
var ReactHeatmap = require('react-heatmap');
let data = [{ x: 10, y: 15, value: 5}, { x: 50, y: 50, value: 2}, ...];
`

, lib and the build process)NOTE: The source code for the component is in src. A transpiled CommonJS version (generated with Babel) is available in lib for use with node.js, browserify and webpack. A UMD bundle is also built to dist, which can be included without the need for any build system.
To build, watch and serve the examples (which will also watch the component source), run npm start. If you just want to watch changes to src and rebuild lib, run npm run watch (this is useful if you are working with npm link`).
