React Habitat

React Habitat <3 Your CMS

React Habitat is designed for integrating React with your CMS using the DOM as the interface. It's based of some basic container programming principles and brings peace and order to multi page apps.

This framework exists so you can get on with the fun stuff!

When to use React Habitat

You should use React Habitat any time there is a framework or CMS rendering your HTML and you want one or multiple React components on the page(s). For example sometimes there are only sections of your page that you want to be a React Component, then this framework is perfect for that.

The idea behind this is that, rather than trying to initiate one or many React components; by either hard coding or using a Router. You switch it around so components "new up" themselves when required.

React Habitat works great with:

Sitecore
Adobe Experience Manager
Umbraco
Drupal
Joomla
WordPress
Magento
...etc

When not to use it

Typically if you're building a full-on one page React app that yanks data from restful API's... then this framework isn't really going to bring much benefit to you. However you are definitely invited to use it if you want to.

Features

Tiny code footprint (only 8KB)
Redux supported by including react-habitat-redux
Pass data (props) to your components directly from HTML attributes and back again
Automatic data/JSON parsing
All page child apps can still share the same components, stores, events etc. (Everything is connected)
Simple to swap out components for others (The beauty of IOC containers)
For advanced users, you can use different components for different build environments
100% W3C HTML5 Valid
TypeScript definitions included (see notes)

Compatibility

Supports Browsers IE9+ and all the evergreens. (IE9-11 will require an "Object.assign" Pollyfill)
ES5, ES6/7 & TypeScript
React v15 and up

We highly recommend you use something like WebPack or Browserify when using this framework.

Installing

Install with Node Package Manager (NPM)

npm install --save-dev react-habitat

This assumes that you’re using npm package manager with a module bundler like Webpack or Browserify.

If you don’t yet use npm or a modern module bundler, and would rather prefer a single-file UMD build that makes ReactHabitat available as a global object, you can grab a pre-built version from the dist folder.

Getting Started

Using ES5? Read the ES5 version here.

The basic pattern for integrating React Habitat into your application is:

Structure your app with inversion of control (IoC) in mind.
At application startup...
Create a Container.
Register React components.
Set the container for later use in the DOM.
At application execution...
Use the DOM scope to resolve instances of the components.

This getting started guide walks you through these steps for a simple React application. This document assumes you already know:

How to compile JSX; and
How to bundle using something like webpack or browserify

1. Create a bootstrapper class

The class must extend ReactHabitat.Bootstrapper and is intended to be an entry point of your bundled app. So if you're using something like webpack or browserify then this is file to point it too.

In the constructor() of the class you need to register your React components with it and then set the container. The container is later bound to the DOM automatically so your React components self-initiate.

In React Habitat, you'd register a component for a key something like this

container.register('SomeReactComponent', SomeReactComponent);

So for our sample application we need to register all of our components (classes) to be exposed to the DOM so things get wired up nicely.

import ReactHabitat                 from 'react-habitat';
import SomeReactComponent           from './SomeReactComponent';
import AnotherReactComponent        from './AnotherReactComponent';

class MyApp extends ReactHabitat.Bootstrapper {
    constructor(){
        super();

        // Create a new container builder
        var container = new ReactHabitat.Container();

        // Register your top level component(s) (ie mini/child apps)
        container.register('SomeReactComponent', SomeReactComponent);
        container.register('AnotherReactComponent', AnotherReactComponent);

        // Finally, set the container
        this.setContainer(container);
    }
}

// Always export a 'new' instance so it immediately evokes
export default new MyApp();

You can also register multiple component's all at once with registerAll like this

container.registerAll({
	'SomeReactComponent': SomeReactComponent,
	'AnotherReactComponent': AnotherReactComponent
});

If you are using Redux

You will need to use a different container. Please install & configure the react-habitat-redux library. Then continue with step 2 below.

2. Application execution - render your components

During the web application execution you will want to make use of the components you registered. You do this by resolving them in the DOM from a scope.

When you resolve a component, a new instance of the object gets created (Resolving a component is roughly equivalent to calling 'new').

To resolve new instances of your components you need to attach a data-component attribute to a div or a span element in the HTML. Any child components should be nested inside the React components themselves.

Set the data-component value to equal a component name you have registered in the container.

For instance:

<div data-component="SomeReactComponent"></div>

Will be resolved by the following registration.

container.register('SomeReactComponent', SomeReactComponent);

So, for our sample app we would do something like this

<html>
    <body>
        <div data-component="SomeReactComponent"></div>
        <script src="myBundle.js" />
    </body>
</html>

When you view this page you will see a instance of SomeReactComponent automatically rendered in the div's place. In fact, you can add as many as you like and it will render multiple instances.

For example. This is perfectly valid.

<html>
    <body>

        <div data-component="SomeReactComponent"></div>
        <div data-component="SomeReactComponent"></div>
        <div data-component="SomeReactComponent"></div>

        <script src="myBundle.js" />
    </body>
</html>

Will render 3 instances of your component.

Note It's important that the output built javascript file is included at the end of the DOM just before the closing tag.

Passing properties (props) to your components

Resolving and registering components alone is not all that special, but passing data to it via html attributes is pretty useful. This allows the backend to easily pass data to your components in a modular fashion.

To set props you have a few choices. You can use all of these or only some (they merge) so just use what's suits you best for setting properties.

data-props Maps JSON to props.
data-prop- (Prefix) Maps in strings, booleans, null, array or JSON to a prop.
data-n-prop- (Prefix) Maps in numbers and floats to a prop.
data-r-prop- (Prefix) Maps in a reference to an object that exists on the global scope (window) to a prop.

PLEASE NOTE: The last three options are attribute prefixes. This allow's you to define the property the name. Property names will be automatically converted from hyphens to camel case.

For example

data-prop-title would expose title on the props object inside the component.

data-prop-my-title would expose myTitle on the props object inside the component.

data-props

Set component props via a JSON string on the data-props attribute.

For example

<div data-component="SomeReactComponent" data-props='{"title": "A nice title"}'></div>

data-prop-

Set an component prop via prefixing attributes with data-prop-.

For example

data-prop-title would expose title as a property inside the component.

Please note: JSON, booleans & null are automatically parsed. Eg data-prop-my-bool="true" would expose the value of true, NOT the string representation "true".

Simple Example

<div data-component="SomeReactComponent"
    data-prop-title="A nice title"
    data-prop-show-title="true">
</div>

Would expose props as

class SomeReactComponent extends React.Component {

	constructor(props) {
		super(props);

		props.title === "A nice title";  //> true
		props.showTitle === true;        //> true
	}

	render() {
		return <div>{ this.props.showTitle ? this.props.title : null }</div>;
	}
}

JSON Example

<div data-component="SomeReactComponent"
		data-prop-person="{'name': 'john', 'age': 22}">
</div>

Would expose as

class MyReactComponent extends React.Component {
	constructor(props) {
		super(props);

		return (
			<div>
				Name: {this.props.person.name}
				Age: {this.props.person.age}
			</div>
		);
	}
}

data-n-prop-

Set an component prop with type [number] via prefixing attributes with data-n-prop-.

For example data-n-prop-temperature="33.3" would expose the float value of 33.3 and not the string representation '33.3'.

This is handy if you know that a property is always going to be a number or float.

data-r-prop-

Referenced a global variable in your component prop via prefixing attributes with data-r-prop-.

For Example

<script>
    var foo = window.foo = 'bar';
</script>

<div data-component="SomeReactComponent" data-r-prop-foo="foo"></div>

This is handy if you need to share properties between habitats or you need to set JSON onto the page.

Passing values back again

It can be handy to pass values back again, particularly for inputs so the backend frameworks can see any changes or read data.

Every React Habitat instance is passed in a prop named proxy, this is a reference the original dom element. Please note only <inputs /> are left in the DOM by default. To keep a generic element in the DOM, set the data-habitat-no-replace="true" attribute.

So for example, we could use proxy to update the value of an input like so

<input id="personId" type="hidden" data-component="personLookup" />

Somewhere inside the component

this.props.proxy.value = '1234'

Sometimes you may additionally need to call this.props.proxy.onchange() if you have other scripts listening for this event.

Options and Methods

Using ES5? Read the ES5 version here.

Setting the habitat's css class

You can set a custom css class on the habitat element by setting the data-habitat-class attribute on the target element.

Example

<div data-component="MyComponent" data-habitat-class="my-css-class"></div>

Will result in the following being rendered

<div data-habitat="C1" class="my-css-class">...</div>

Replace original node

By default only <inputs /> are left in the DOM when a React Habitat is created.

To keep a generic element in the DOM, set the data-habitat-no-replace="true" attribute.

Changing the habitat query selector

Default: 'data-component'

By default React Habitat will resolve components via the data-component attribute. You can configure this by assigning the componentSelector property in your constructor.

It will accept any string containing any valid attribute name.

Example

class MyApp extends ReactHabitat.Bootstrapper {
	constructor(){
		super();

		this.componentSelector = 'data-myComponents';
	}
}

Disposing the container

To unload the container and remove all React Habitat instances. Call the dispose() method.

Example

class MyApp extends ReactHabitat.Bootstrapper {
	constructor(){
		super();

		...

		this.dispose();
	}
}

TypeScript users please note

We are using Babel to transpile our code which wraps our modules in a "fake" module with a default property. TypeScript doesn't do any of the default wire up magic (see here for more details).

So in order for TypeScript to consume our modules you will need to:

Change ReactHabitat.Bootstrapper for ReactHabitat.default.Bootstrapper; and
Change ReactHabitat.Container for ReactHabitat.default.Container
