const App=()=>{
 const [labelcmp, setLabelCmp] = useState(null);
 const labelcmpRef = useRef();
 labelcmpRef.current = labelcmp;
 const [labeltext, setLabelText] = useState('initial text');
 const [row, setRow] = useState(null);

 return (
  < div style={{
   boxSizing:'border-box',height:'100%',
   display:'flex',flexDirection:'column'
  }}>
   < ReExt xtype='logo'/>
   < div style={{display:'flex'}}>
    < ReExt xtype='button'
     config={{text:'click me',width:100,ariaLabel:'demobutton'}}
     onTap={()=>{
      labelcmpRef.current.setHtml('set using method call');
      setLabelText('set using state');
     }}
    />
   < /div>
   < ReExt xtype='grid'

    }}
    onSelect={(grid, selected)=>{
     var row = selected[0].data
     setRow(row)
     var rowString = JSON.stringify(row)
     labelcmpRef.current.setHtml(rowString)
     setLabelText(rowString)
    }}
   />
   < div style={{flex:1,padding:20,border:'1px solid gray'}}>
    {row !== null &&
     <>
     < ReExt xtype='label' config={{html: `name: ${row.name}`}}/>
     < ReExt xtype='label' config={{html: `email: ${row.email}`}}/>
     < ReExt xtype='label' config={{html: `phone: ${row.phone}`}}/>
     
    }
   
   < div style={{flex:1,padding:20,border:'1px solid gray'}}>
    < ReExt xtype='label'
     config={{html:'initial text'}}

      setLabelCmp(cmp)
     }}
    />
    < ReExt xtype='label'
     config={{html:labeltext}}
    />
   
  
 )
}
export default App

Run the Application

• Create React App: Run npm start.
• Vite: Run npx vite –open.

ReExt Component

The ReExt React component has 5 static props (only xtype is required) and any number of optional event props
Example: ReExt Button

< ReExt xtype='button'
 className='okbutton'
 style={{color:'green'}}
 references={false}
 child={false}
 config={{text:'OK'}}
 ready={(cmp)=>{console.log(cmp)}}
 onTap={(button,e,eOpts)=>{console.log(`${button.text}`)}}
/>

Here are the links to the Ext JS documentation from the example above:

• xtype=’button’
• config={{text:’click me’}}
• onTap={(button,e,eOpts)=>{console.log(${button.text})}}/a>

More details on the ReExt props

• xtype (required): the xtype of the component as defined in Sencha documentation.
• className (optional): the css class to be attached to the parent div of the underlying Ext JS component (each underlying ExtJS component is wrapped with a parent div that is width:’100%’ and height: ‘100%’ – unless overwritten in the className or style config)
• style (optional): the css style to be attached to the parent div of the ExtJS component.
• references (optional): used if using an Ext JS reference.
• config (optional): a JavaScript object with the configs of the component as defined in Sencha documentation.
• ready(cmp) (optional): the event that is fired by the ReExt component when the underlying ExtJS component is created. The value of this config is a function in your React hosting component with the parameter being the created ExtJS object.
• storeloaded(store, cmp) (optional): the event that is fired by the ReExt component when the async store associated with the component is loaded.
• ‘on’ props (optional): a prop that corresponds to an event fired by the ExtJS component; follow the pattern of ‘on’ with the first letter of the event capitalized. (ie, the button xtype has a tap event, and the corresponding prop is onTap). The value of this prop is a function in your React hosting component.

ReExt configs and events

ReExt utilizes the Ext JS framework components by providing a value for the ReExt ‘xtype’ prop. This prop maps to the xtype in the ExtJS documentation. You can search for any xtype in the upper right corner of the Ext JS documentation page.
For Example for the classic toolkit maps to this page in the Ext JS 7.8 documentation:

configs
The configs tab shows all values valid for the ReExt ‘config’ prop.

events
The events tab shows all events – to use, prepend ‘on’ and capitalize the first letter of the event name:

For example, here is the page for the ReExt ‘onClick’ event {}}/>

methods

The methods tab shows all methods that can be called with the cmp parameter of the ReExt ready event {cmp.setText(‘new text’)}}/>

Custom Ext JS Components

To use custom Ext JS components:

1. Create a component using Ext JS definitions (e.g., MainList.jsx).
2. Import and use this component in your React application.

in ./app/layout.js`

'use client';
import { ReExtProvider } from '@sencha/reext';

export default function RootLayout({ children }) {
  var ReExtData = { 
  sdkversion: '7.8.0', 
  toolkit: 'classic', 
  theme: 'classic', 
  urlbase: './', 
  location: 'local' 
  };
  return (
    < html lang="en">
      < body>
          < ReExtProvider ReExtData={ReExtData}>
            {children}
          
      
    
  )
}

Custom ExtJS components can now be added as an import.
in app/personnel/page.js`

'use client'
import ReExt from '@sencha/reext';
import { useState, useEffect } from 'react';

export default function Page() {
  const [ready, setReady] = useState(false);
  useEffect(() => {
    const doAsync = async () => {
      try {
        await import('./MainList');
        setReady(true)
      } catch (e) {
        console.error('fail', e)
      }
    }
    doAsync()
  }, []);
  if (!ready) {
    return < div>Loading...
  }
  else {
    return (
      < ReExt xtype='mainlist'
        style={{ flex: 2, border: '1px solid gray' }}
        onSelect={(sender, record) => 
        { 
            console.log('row selected', record[0])
        }}
      />
    )
  }
}

in ./MainList.jsx`

import './PersonnelStore'
Ext.define('ReExt.view.main.List', {
    extend: 'Ext.grid.Panel',
    xtype: 'mainlist',
    store: { type: 'personnel' },
    columns: [
        { text: 'Name', dataIndex: 'name' }
    ]
})

in ./PersonnelStore.jsx`

Ext.define('ReExt.store.Personnel', {
    extend: 'Ext.data.Store',
    alias: 'store.personnel',
    data: { items: [
{name:'Jean Luc',email:"[email protected]",phone:"555-111-1111"},
{name:'Worf',email:"[email protected]",phone:"555-222-2222"},
{name:'Deanna',email:"[email protected]",phone:"555-333-3333"},
{name:'Data',email:"[email protected]",phone:"555-444-4444"}
    ]},
    proxy: {
     type: 'memory',
     reader: {
      type: 'json',
      rootProperty: 'items'
     }
    }
   })
