react-control-statements

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

Install

npm install --save react-control-statements

Usage

If

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

import React, { Component } from 'react'
import { If } from 'react-control-statements'
 
class YourComponent extends Component {
  render() {
    <If condition={ test }>
      <span>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-control-statements'
 
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>
    );
  }
}

For

For syntax.

import React, { Component } from 'react'
import { For } from 'react-control-statements'
 
class YourComponent extends Component {
  render() {
    return (
      <div>
        <For each="$item" of={ this.props.items }>
          <span key="$item.id">$item.title</span>
        </For>
      </div>
    );
  }
}
