react-logical

A collection of components for reducing inline logic in your React apps

Installation

Add react-logical to your project:

$ yarn add react-logical

Or with npm:

$ npm install --save react-logical

Usage

We rarely want to display a blank string, so when a prop gets passed down, we inevitably have to do some checks. This can introduce pockets of curly braces with error prone boolean logic and ternary statements.

Instead of writing this:

import React from 'react';

const Greeting = ({ name }) => {
  return (
    <h1>
      {'Hello, '}
      {name && name.length > 0 ? name : 'World'}
      {'!'}
    </h1>
  );
}

Import String and write this:

import React from 'react';
import { String } from 'react-logical';

const Greeting = ({ name }) => {
  return (
    <h1>
      {'Hello, '}
      <String str={name} blankStr={'World'} />
      {'!'}
    </h1>
  );
}

We've removed a ternary statement from the component and made it more declarative. Yay!
