Render When

A zero-dependency lightweight clean conditional rendering component for React.

It works similar to if-else and switch case. If first condition gets true in the children tree, then only that one will be executed. An optional props limit will allow to limit the number of true conditions to render at a time. By default limit is 1. There is another optional props isTrue in ReactWhen which allows you to set condition for entire parent conditional component.

RenderWhen Component

Prop Name	Is Required	Default Value
children	Yes	-
isTrue	No	true
limit	No	1

RenderWhen.If Component

Prop Name	Is Required	Default Value
children	Yes	-
isTrue	Yes	-

Examples

Example 1:

import React from 'react';

export function App(props) {
  const x = 2;

  return (
    <RenderWhen>
      <RenderWhen.If isTrue={x === 2}>
        Hello 2
      </RenderWhen.If>
      <RenderWhen.If isTrue={x === 2}>
        Bye 2
      </RenderWhen.If>
    </RenderWhen>
  );
}

Example 2:

export function App(props) {
  const day = 'Monday';

  return (
    <RenderWhen>
      <RenderWhen.If isTrue={day === 'Sunday'}>
        Let's go to picnic!
      </RenderWhen.If>
      <RenderWhen.If isTrue={day === 'Saturday'}>
        Let's plan for weekend man!
      </RenderWhen.If>
      <RenderWhen.If isTrue={day === 'Friday'}>
        Party tonight
      </RenderWhen.If>
      <RenderWhen.If isTrue>
        Boring weekdays
      </RenderWhen.If>
    </RenderWhen>
  );
