react-conditional-render

install

npm install --save react-conditional-render

Usage

let say you have a React component define like

import React from 'react';

export default React.createClass({
  displayName: 'UserProfile',
  render() {
    return (
      <li>
        <div>Name : {this.props.user.name}</div>
        <div>Age : {this.props.user.age}</div>
        <div>Email : {this.props.user.email}</div>
      </li>
    );
  },
});

You can compose this component with react-conditional-render to use conditional rendering

import React from 'react';
import { withConditionalRendering } from 'react-conditional-render';

const UserProfile = React.createClass({
  displayName: 'UserProfile',
  render() {
    return (
      <li>
        <div>Name : {this.props.user.name}</div>
        <div>Age : {this.props.user.age}</div>
        <div>Email : {this.props.user.email}</div>
      </li>
    );
  },
});

export default withConditionalRendering(UserProfile);

Then you can use this component in other component and use the condition property to render the UserProfile only if the condition property value is truthy (or a function that returns a truthy value)

import React from 'react';
import UserProfile from './userprofile';

export default React.createClass({
  getInitialState() {
    return {
      users: UserStore.all()
    };
  },
  render() {
    return (
      <ul>
        {this.state.users.map(user =>
          <UserProfile key={user.id} user={user} condition={user.age > 42} />)}
      </ul>
    );
  },
});

You can also just wrap some HTML elements with the Wrapper component

import React from 'react';
import { Conditional } from 'react-conditional-render';

export default React.createClass({
  getInitialState() {
    return {
      users: UserStore.all()
    };
  },
  render() {
    return (
      <ul>
        {this.state.users.map(user => (
          <Conditional key={user.id} condition={user.age > 42}>
            <li>
              <div>Name : {user.name}</div>
              <div>Age : {user.age}</div>
              <div>Email : {user.email}</div>
            </li>
          </Conditional>
        ))}
      </ul>
    );
  },
});
