Introduction
- React 18 Working Group
Create React App with Vite React Template
Deploy to Netlify

All of this project's code can be found in the First Look monorepo on my GitHub.

Introduction

When it's released, React 18 will include out-of-the-box improvements including:

Automatic batching
New APIs like startTransition
A new streaming server renderer with built-in support for React.lazy

The React team has also taken a new step by creating the React 18 Working Group to provide feedback, ask questions, and collaborate on the release. The Working Group is hosted on GitHub Discussions and is available for the public to read.

React 18 Working Group

Members of the working group can leave feedback, ask questions, and share ideas. The core team will also use the discussions repo to share their research findings. As the stable release gets closer, any important information will also be posted on the React blog.

Because an initial surge of interest in the Working Group is expected, only invited members will be allowed to create or comment on threads. However, the threads are fully visible to the public, so everyone has access to the same information. The team believes this is a good compromise between creating a productive environment for working group members, while maintaining transparency with the wider community.

No specific release date is scheduled, but the team expects it will take several months of feedback and iteration before React 18 is ready for most production applications.

Library Alpha: Available today
Public Beta: At least several months
Release Candidate (RC): At least several weeks after Beta
General Availability: At least several weeks after RC

More details about the projected release timeline are available in the Working Group.

Create React App with Vite React Template

yarn create vite ajcwebdev-react18 --template react

Install Dependencies and Start Development Server

cd ajcwebdev-react18
yarn
yarn dev

If we look in our package.json we'll see React 18 is already included in the Vite template.

{
  "name": "ajcwebdev-react18",
  "type": "module",
  "scripts": {
    "dev": "vite",
    "build": "vite build",
    "preview": "vite preview"
  },
  "dependencies": {
    "react": "^18.2.0",
    "react-dom": "^18.2.0"
  },
  "devDependencies": {
    "@types/react": "^18.0.28",
    "@types/react-dom": "^18.0.11",
    "@vitejs/plugin-react": "^4.0.0",
    "vite": "^4.3.2"
  }
}

Use esbuild.jsxInject to automatically inject JSX helper imports for every file transformed by ESBuild:

// vite.config.js

import { defineConfig } from 'vite'
import reactRefresh from '@vitejs/plugin-react-refresh'

export default defineConfig({
  plugins: [reactRefresh()],
  esbuild: {
    jsxInject: `import React from 'react'`
  }
})

Root Component

// src/main.jsx

import ReactDOM from 'react-dom'
import './index.css'
import App from './App'

const root = ReactDOM.createRoot(
  document.getElementById('root')
)

root.render(<App />)

App Component

// src/App.jsx

import logo from './logo.svg'
import './App.css'

function App() {
  return (
    <div className="App">
      <header className="App-header">
        <img src={logo} className="App-logo" alt="logo" />
        <p>React 18 Deployed on Netlify with Vite</p>
      </header>
    </div>
  )
}

export default App

Deploy to Netlify

echo > netlify.toml

# netlify.toml

[build]
  publish = "dist"
  command = "yarn build"

Initialize a Git repository and push to GitHub.

git init
git add .
git commit -m "init"
gh repo create ajcwebdev-react18 \
  --public \
  --push \
  --source=. \
  --description="An example React 18 application deployed to Netlify with Vite" \
