React Slot and Fill

🚀 React Slot and Fill pattern implementation made with React.createContext API. Check out the demo.

Install

You can install this library via NPM or YARN.

NPM

npm i @blackbox-vision/react-slot-fill

YARN

yarn add @blackbox-vision/react-slot-fill

Use case

If you need to render a component from somepart of the DOM tree, but it needs to be visible in another part of the tree, this library solves it.

This library is very similar to react-slot-fill, but we solve two particular issues:

• Support for React.createContext, this library is intended to use with React >= 16.3.1.
• If a Fill is declared after a Slot, it can render properly, which react-slot-fill doesn't support.

Usage

The usage is really simple:

// Toolbar.js
import React from 'react';
import { Slot, Fill } from '@blackbox-vision/react-slot-fill';

const Toolbar = (props) => (
  <div>
    <Slot name="Toolbar.Item" />
  </div>
);

export default Toolbar;

Toolbar.Item = (props) => (
  <Fill name="Toolbar.Item">
    <button>{props.label}</button>
  </Fill>
);

// Feature.js
import React from 'react';
import Toolbar from './Toolbar';

const Feature = () => <Toolbar.Item label="My Feature!" />;

// App.js
import React from 'react';
import ReactDOM from 'react-dom';
import { Provider } from '@blackbox-vision/react-slot-fill';

import Toolbar from './Toolbar';
import Feature from './Feature';

const App = () => (
  <Provider debug={true || false}>
    <Toolbar />
    <Feature />
  </Provider>
);

ReactDOM.render(<App />, document.getElementById('root'));

Props

Slot and Fill components use the same props, which are the following ones:

Properties	Types	Default Value	Description
name	string	none	Determines the name of the Slot/Fill.
debug	boolean	false	Enable logging to detect issues with Slot/Fill.

TODO

• Support for passing props from Fill to Slot.
• Support for multiple Fill for one Slot.
