React Abode

React Abode is a simple React micro-frontend framework allowing you to host multiple react components by defining HTML.

Features

Prop passing

React Abode allows you to pass props to your React components by using a data-prop-prop-name attribute. All props need to be prefixed by data-prop-. Props will automatically be converted from kebab-case to camelCase.

<div data-component="Price" data-prop-sku="123456"></div>

Script props

React Abode allows you to pass data-prop- props to the script. These can then be consumed inside your bundle by using getScriptProps(). This is useful when you need to have a prop available in every component.

<script
  src="your/bundle/location.js"
  data-prop-global-prop="some prop you want in all your components"
></script>

const scriptProps = getScriptProps();
console.log(scriptProps.globalProp);

Prop parsing

By default all supplied props will be parsed with JSON.parse. In case a prop should be parsed differently, custom parse functions can be provided to register or getScriptProps.

// <div data-component="Product" data-prop-sku="1234" data-prop-is-available="true" data-prop-price="10.99" >
register('Product', () => import('./modules/Product/Product'), {
  propParsers: {
    sku: prop => String(prop),
    isAvailable: prop => Boolean(prop),
    price: prop => Float(prop),
  },
});
// <script data-prop-global="1234"></script>
getScriptProps({ propParsers: { global: prop => String(prop) } });

Automatic DOM node detection

When DOM nodes are added, for example when loading more products in a catalog on a SPA, React Abode will automatically detect them and populate them with your React components. When a DOM node containing a hosted React component is removed, the component is unmounted.

Update on prop change

When the props for your components change, React Abode will rerender these components. This can be very useful when nesting multiple layers of front-end frameworks.

How to use

Create a bundle with one or more abode registered components. This takes the place of the App component in a create-react-app, which links the top level react component to the html page. When all components are registered, call populate. Build and host this bundle on your platform of choice.

// src/modules/Cart/Cart.tsx
const Cart = (): JSX.Element => {
  return <h1>a shopping cart</div>;
};

// src/App.tsx
import { populate, register } from 'react-abode';

// Import can be used to register component
register('Cart', () => import('./modules/Cart/Cart'));

// Component can also be used directly
import Cart from './modules/Cart/Cart';

register('Cart', () => React.memo(Cart));

populate({ attributes: { classname: 'some-class-name' } });

Include a div with the selector in your HTML. Load the bundle in a script tag inside the <body> </body>. On loading the page, React Abode will check for components with the matching selector, which is data-component by default.

<html>
  <body>
    <div data-component="Cart">
      This text wil be replaced by your react component
    </div>
    <script src="your/bundle/location.js"></script>
  </body>
</html>

Options

Utility functions

setComponentSelector

If you do not want to use data-component you can change the component selector by using setComponentSelector('data-my-component-selector').

getActiveComponents

You can use getActiveComponents to get a list of all Abode elements currently in your DOM.

getRegisteredComponents

You can use getRegisteredComponents to get all registered components.

Populate parameters

The populate function can be passed an object with options.

| name | type | purpose | example | | ---------- | -------- | ------------------------------------------------------------------------------------------- | ------------------------------------------------------- | | attributes | object | attributes which will be aplied to every react-abode container | {attributes: { classname: "some-class-name"}} | | callback | function | function which will be executed every time a new batch of react-abode elements is populated | () => console.log('new abode elements added to page') |
