React Option Component

A simple component to make more declarative condtional rendering. It exports 3 components that are used together.

• Option
• Some
• None

The Option component wraps Some and ~None components. It takes a single prop value which evaluates to true or false. If the value prop evaluates to true then the Some component including all it's children are rendered. If the value prop evaluates to false then the None component and all it's children are rendered.

Currently the Option component will only use the first Some or None component it finds. However you can nest ~Option components inside other ~Option, Some, or None components.

Note that you could have only a Some component and if value prop evaluates to false then it will return null and nothing will be rendered.

Basic Usage Examples

import { Option, Some, None } from 'react-option';

const TestComponent = (props) => (
  <div>
    <Option value={ props.shouldRender() }>
      <Some>
        <p>I will be rendered if props.shouldRender return true</p>
      </Some>
      <None>
        <p>Or I will be rendered if props.shouldRender returns false</p>
      </None>
    </Option>
  </div>
)

Nested Options

import { Option, Some, None } from 'react-option'

const TestComponent = (props) => (
  <div>
    <Option value={ props.shouldRender() }>
      <Some>
        <p>Should render</p>
        <Option value={ props.someOtherCondition() }>
          <Some>
            <p> should render if both are true</p>
          </Some>
          <None>
            <p> Should render if first is true and second is false</p>
          </None>
        <Option>
      </Some>
      <None>
        <p>Should not render</p>
      </None>
    </Option>
  </div>
)
