React Create Portal

Render elements through a Portal, give you more control over your UI, e.g. rendering a button into footer inside your deeply nested component

Principles

• Declarative
• Start quickly
• Reasonable
• Test friendly

Prerequisites

• New React Context API
• ReactDOM Portal

Get Started

npm install react-create-portal

or

yarn add react-create-portal

Examples

1. render different contents based on current route

// App.js
import React from "react"
import { PortalProvider, createPortal } from "react-create-portal"

const [
  Slot, // place Slot at where elements render
  Render, // Render's children will be portaled into Slot
] = createPortal()

const App = () => (
  <PortalProvider>
    <div>
      Hello <Slot />!
    </div>
    <Router>
      <Route path="/world">
        <Render>World</Render>
      </Route>
      <Route path="/react">
        <Render>React</Render>
      </Route>
    </Router>
  </PortalProvider>
)

/** output dom
 * <div>Hello World!</div> // /world renders "Hello World!"
 * <div>Hello React!</div> // /react renders "Hello React!"
 */

2. fallback UI when no Render rendered

// App.js
const App = () => (
  <PortalProvider>
    <div>
      Hello <Slot fallback="World" />!
    </div>
    <Router>
      <Route path="/world">
        <div>World Page</div>
      </Route>
      <Route path="/web">
        <div>Web Page</div>
      </Route>
      <Route path="/react">
        <Render>React</Render>
      </Route>
    </Router>
  </PortalProvider>
)

/** output dom
 * <div>Hello World!</div> // /world renders "Hello World!"
 * <div>Hello World!</div> // /web renders "Hello World!"
 * <div>Hello React!</div> // /react renders "Hello React!"
 */
