react-live

React-live is a flexible and interactive code editor component for React applications. It allows developers to create live code playgrounds within their projects, enabling real-time code editing and execution. This library is particularly useful for creating interactive documentation, tutorials, or code demonstrations.

Pros

• Provides a seamless, interactive coding experience within React applications
• Supports custom syntax highlighting and theming
• Offers flexibility with customizable error boundaries and scope
• Enables live code editing and execution in real-time

Cons

• May have a learning curve for developers unfamiliar with code editor components
• Limited to React-based projects
• Potential performance impact when rendering complex code examples
• Requires careful consideration of security implications when allowing user input

Code Examples

1. Basic usage of LiveProvider and LiveEditor:

import { LiveProvider, LiveEditor, LiveError, LivePreview } from 'react-live'

const code = `
function App() {
  return (
    <h1>Hello, React-live!</h1>
  )
}
`

function MyComponent() {
  return (
    <LiveProvider code={code}>
      <LiveEditor />
      <LiveError />
      <LivePreview />
    </LiveProvider>
  )
}

2. Using custom theme and language:

import { LiveProvider, LiveEditor } from 'react-live'
import { dracula } from 'prism-react-renderer/themes/dracula'

const code = `const greeting = 'Hello, World!';
console.log(greeting);`

function CustomEditor() {
  return (
    <LiveProvider code={code} language="javascript" theme={dracula}>
      <LiveEditor />
    </LiveProvider>
  )
}

3. Implementing a custom scope:

import { LiveProvider, LiveEditor, LivePreview } from 'react-live'
import { Button } from './components'

const code = `
function App() {
  return (
    <Button onClick={() => alert('Clicked!')}>
      Click me
    </Button>
  )
}
`

function ScopedExample() {
  return (
    <LiveProvider code={code} scope={{ Button }}>
      <LiveEditor />
      <LivePreview />
    </LiveProvider>
  )
}

Getting Started

To use React-live in your project, follow these steps:

1. Install the package:

npm install react-live

2. Import the necessary components:

import { LiveProvider, LiveEditor, LiveError, LivePreview } from 'react-live'

3. Set up a basic live code editor:

const code = `function Greeting() { return <h1>Hello, World!</h1> }`

function App() {
  return (
    <LiveProvider code={code}>
      <LiveEditor />
      <LiveError />
      <LivePreview />
    </LiveProvider>
  )
}

This setup creates a live code editor with error handling and a preview of the rendered component.
