A simple React component for exposing global properties on your page. This library is particularly useful for isomorphic apps, where a set of values must be shared between the server and client (e.g. passing initialization variables to third-party libraries).
npm install react-globalvarGlobal=require('react-global');<Globalvalues={{FOO: this.props.foo,BAR: this.props.bar}}/>Global.get('FOO')Note: every Global variable that you declare will actually be available on the window object as a true browser global.
Global.get('FOO')===window.FOO===window['FOO']===FOOThis component is meant to ease the case where your isomorphic app's server has some configuration variable's that need to be shared with the browser that will never change over the course of the user's interaction with your app. Below you will find a reusable pattern for accomplishing this task cleanly and concisely using react-global.
server.js
varReact=require('React'),App=require('./views/App.jsx');app.get('/',function(req,res){varmarkup=React.renderToString(<AppclientApiKey={config.client.api.key}/>);res.send('<!DOCTYPE html>'+markup);});App.jsx
varReact=require('react'),Global=require('react-global');varApp=React.createClass({componentDidMount: function(){ClientLib.init(this.props.clientApiKey);},render: function(){
...
<Globalvalues={{CLIENT_API_KEY: this.props.clientApiKey}}/>...}});// Mount the app if in the browserif(window&&document){React.render(<AppclientApiKey={Global.get('CLIENT_API_KEY')}/>}A simple but useful pattern!
