react-conditioner

How many times have you written ternary statements like this in your JSX code?

class YourComponent extends Component {
  render() {
    return (
      <div>
        { loading
          ? <Loading>Loading...</Loading>
          : <Content>
              <div>Content</div>
            </Content>
        }
      </div>
    )
  }
}

Ugly? not readable? yes!

There's no built-in conditional syntax in React. This library adds the syntactic sugar to write conditionals as component. Inspired by jsx control statements

Install

npm install --save react-conditioner

Usage

If

The body of the if statement only gets evaluated if condition is true.

import React, { Component } from 'react'
import { If } from 'react-conditioner'
 
class YourComponent extends Component {
  render() {
    <If condition={ test }>
      <span>Truth</span>
    </If>
    <If condition={ !test }>
      <span>Second Truth</span>
    </If>
  }
}

Choose

This is an alternative syntax for more complex conditional statements.

import React, { Component } from 'react'
import { Choose, When, Otherwise } from 'react-conditioner'
 
class YourComponent extends Component {
  render() {
    return (
      <div>
        <Choose>
          <When condition={ test1 }>
            <span>IfBlock</span>
          </When>
          <When condition={ test2 }>
            <span>ElseIfBlock</span>
            <span>Another ElseIfBlock</span>
            <span>...</span>
          </When>
          <Otherwise>
            <span>ElseBlock</span>
          </Otherwise>
        </Choose>
      </div>
    );
  }
}
