react-renderif allows you to create a custom wrapper component with a callback prebound.
This callback will be passed a property
prop that can be used if you desire.
var React = require('react');
var RenderIf = require('react-renderif');
var RenderIfFoo = RenderIf.createCustomMatcher(function(property) {
return property === 'foo';
});
// ...
<RenderIfFoo property={'foo'}>
<h1>Rendered</h1>
</RenderIfFoo>
// ...
// Testing
npm test
// Building
npm install
npm run build
