react-render-when

Conditionally render a component

Installation

Add @mariosant/react-render-when to your package.json.

$ npm install @mariosant/react-render-when

You can now import the module and use it like

import {renderWhen, renderUnless} from '@mariosant/react-render-when';

Usage

Both renderWhen and renderUnless take 2 parameters. A predicate function and a React component.

Check out the following example:

import {renderWhen} from '@mariosant/react-render-when';

const needsCowbell = ({cowbells}) => cowbells < 10;

const Advice = renderWhen(needsCowbell, () => <p>Needs more cowbell</p>)

<Advice cowbell={1} />    // will render
<Advice cowbell={100} />  // will not render

The predicate inverses when using renderUnless:

import {renderUnless} from '@mariosant/react-render-when';

const enoughCowbell = ({cowbells}) => cowbells >= 10;

const Advice = renderUnless(enoughCowbell, () => <p>Needs more cowbell</p>)

<Advice cowbell={1} />    // will render
<Advice cowbell={100} />  // will not render
