Installation

npm i @uiw/react-iframe

Basic Usage

import React from 'react';
import IFrame from '@uiw/react-iframe';

export default function Demo() {
  return (
    <IFrame>
      <h1>Hello World!</h1>
    </IFrame>
  );
}

`head`

The head prop is a dom node that gets inserted before the children of the frame.

import React from 'react';
import IFrame from '@uiw/react-iframe';

const head = (
  <style>{`body { background: red; }`}</style>
);

export default function Demo() {
  return (
    <IFrame head={head}>
      <h1>Hello World!</h1>
    </IFrame>
  );
}

`initialContent`

The initialContent props is the initial html injected into frame. It is only injected once, but allows you to insert any html into the frame (e.g. a <head> tag, <script> tags, etc). Note that it does not update if you change the prop.

Defaults to <!DOCTYPE html><html><head></head><body></body></html>

import React from 'react';
import IFrame from '@uiw/react-iframe';

const initialContent = '<!DOCTYPE html><html><head><title>React IFrame</title><meta name="keywords" content="react,iframe,component,development" /></head><body></body></html>';

export default function Demo() {
  return (
    <IFrame initialContent={initialContent}>
      <div style={{ fontSize: 32, color: 'red' }}>Hello World!</div>
    </IFrame>
  );
}

`mountTarget`

The mountTarget attribute is a css selector (#target/.target) that specifies the child within the initial content of the iframe to be mounted.

import React from 'react';
import IFrame from '@uiw/react-iframe';

const initialContent = '<!DOCTYPE html><html><head></head><body><h1>i wont be changed</h1><div id="mountHere"></div></body></html>';

export default function Demo() {
  return (
    <IFrame initialContent={initialContent} mountTarget="#mountHere">
      <div style={{ fontSize: 32, color: 'red' }}>Hello World!</div>
    </IFrame>
  );
}

`ref`

The ref prop provides a way to access inner <iframe> DOM node.

import React, { useEffect, useState, Fragment } from 'react';
import IFrame from '@uiw/react-iframe';

export default function Demo() {
  const [iframeRef, setIframeRef] = useState();
  const [count, setCount] = useState(0);

  useEffect(() => {
    if (iframeRef) {
      iframeRef.focus();
    }
  }, [iframeRef]);

  const click = () => setCount(count + 1);
  return (
    <Fragment>
      <button onClick={click} style={{ display: 'flex' }}>Click</button>
      <IFrame ref={(node) => node && setIframeRef(node)}>
        <div>Hello World!</div>
        <div style={{ fontSize: 32, color: 'red' }}>{count}</div>
      </IFrame>
    </Fragment>
  );
}

`src`

Open a URL in an <iframe>.

import React, { useEffect, useState, Fragment } from 'react';
import IFrame from '@uiw/react-iframe';

export default function Demo() {
  return (
    <IFrame src="https://wangchujiang.com/" style={{ width: '100%', height: 320 }} />
  );
}

Accessing the iframe's `window` and `document`

The iframe's window and document may be accessed via the FrameContext.Consumer or the useFrame hook.

import React, { useEffect, useState, Fragment } from 'react';
import IFrame, { FrameContext } from '@uiw/react-iframe';

export default function Demo() {
  return (
    <IFrame>
      <FrameContext.Consumer>
        {({ document, window }) => {
          return (
            <div>
              <div>Hello World!</div>
            </div>
          )
        }}
      </FrameContext.Consumer>
    </IFrame>
  );
}

The example with useFrame hook:

import React, { useEffect, useState, Fragment } from 'react';
import IFrame, { useFrame } from '@uiw/react-iframe';

const InnerComponent = () => {
  // Hook returns iframe's window and document instances from Frame context
  const { document, window } = useFrame();
  return (
    <div>
      <div>Hello World!</div>
    </div>
  );
};

export default function Demo() {
  return (
    <IFrame>
      <InnerComponent />
    </IFrame>
  );
}

Event

import React, { useEffect, useState, Fragment } from 'react';
import IFrame, { useFrame } from '@uiw/react-iframe';

const InnerComponent = () => {
  // Hook returns iframe's window and document instances from Frame context
  const { document, window } = useFrame();
  return (
    <div>
      <div>Hello World!</div>
    </div>
  );
};

export default function Demo() {
  const onLoad = (evn) => {
    console.log("iframe loaded successfully!", evn)
  }
  return (
    <IFrame onLoad={onLoad}>
      <InnerComponent />
    </IFrame>
  );
}

Props

export interface IFrameProps extends React.HTMLAttributes<HTMLIFrameElement> {
  head?: React.ReactNode;
  initialContent?: string;
  mountTarget?: string;
}
declare const IFrame: import("react").ForwardRefExoticComponent<IFrameProps & import("react").RefAttributes<HTMLIFrameElement>>;
export default IFrame;

Development

Runs the project in development mode.

# Step 1, run first, listen to the component compile and output the .js file
# listen for compilation output type .d.ts file
npm run watch
# Step 2, development mode, listen to compile preview website instance
npm run start

Builds the app for production to the build folder.

npm run build

The build is minified and the filenames include the hashes. Your app is ready to be deployed!
