The Ext JS Reactor: Use Your Favourite Ext JS Components Inside React

Integration of Ext JS components into a React application is a nice combo. You have powerful Ext JS’s pre-built UI components in the flexible, React reusable system. It’s like having the best of both worlds, rich JavaScript components and smooth React elements. Just a heads-up, though: it’s not always a drag-and-drop setup. Some tweaks might be needed.

But if you’re looking for a strong JavaScript UI component library to boost your app’s design, this combo is definitely worth checking out. That’s where ReExt comes in. It helps in using Ext JS’s pre-built UI components inside your React app, and the amazing thing is that you don’t have to rewrite anything. So, you can easily mix Ext JS’s strong, structured setup with React’s flexible, component-based style. They both work together nicely.

This blog helps you to understand how ReExt works in a simple, hands-on way. We’ll walk through how to build a simple app and show why it’s considered the best JavaScript UI component library for creating clean, interactive interfaces. We’ll also examine the key benefits and performance.

So, how does ReExt actually work? Basically, it takes Ext JS components and makes them work like regular React JS components. You can drop them in with your usual React elements—no messy workarounds. It all just clicks together smoothly, like they were built to belong in the same UI.

One thing I really like about ReExt is that it just handles stuff. It keeps the UI in sync and takes care of state changes without making a mess. React and Ext JS work together smoothly, so you don’t need to look into the details.

You don’t need to handle unusual bugs. They work quietly in the background. You don’t have to stress about data moving between React and Ext JS. ReExt quietly handles it all for you.

It’s a lifesaver, especially when you’re working with heavy stuff like grids, charts, or forms that need to stay quick and smooth. Think of ReExt like a bridge. It pulls in solid JavaScript UI components and gets them playing nicely with React.

Basically, it gives you the power of a full JavaScript components framework, right inside your React project. Think of it as a bridge between powerful pre built UI components and modern React workflows. If you’re diving into JavaScript web components or hunting for the best UI library for React, ReExt has you covered.

Set up on MacOS

npm create vite@latest reextvite -- --template react-swc
cd reextvite                                                                 
npm install @gusmano/reext@latest
cp node_modules/@gusmano/reext/dist/example/ReExtData.json src/ReExtData.json
cp node_modules/@gusmano/reext/dist/example/App.jsx src/App.jsx
cp node_modules/@gusmano/reext/dist/example/main.jsx src/main.jsx
npx vite _open

This launches your React app with ReExt. The pre-built JavaScript UI components are ready to use.

Create React App Alternative

npx create-react-app reextcra
cd reextcra
npm install @gusmano/reext@latest
cp node_modules/@gusmano/reext/dist/example/ReExtData.json src/ReExtData.json
cp node_modules/@gusmano/reext/dist/example/App.jsx src/App.jsx
cp node_modules/@gusmano/reext/dist/example/main.jsx src/main.jsx
npm start

This method is ideal for developers comfortable with React JS components and looking to integrate a JavaScript components library seamlessly.

Build a Simple Application Using ReExt

Here is a step-by-step guide to building your first app with ReExt:

1. Create a React Application

npx create-react-app reextcra

2. Install Vite (Optional)

npm create vite@latest reextvite -- --template react-swc

3. Install ReExt

npm install @gusmano/reext

4. Install Sencha ExtJS SDK

Place the ExtJS SDK in your project’s public folder. You can use the remote GPL version for testing.

5. Configure ReExtProvider

In main.jsx, wrap your app using ReExtProvider. This is essential to initiate the JavaScript UI components.

import { ReExtProvider } from '@gusmano/reext';
const ReExtData = {
  sdkversion: "7.8.0",
  toolkit: "classic",
  theme: "classic",
  debug: false,
  urlbase: "./",
  location: "remote"
};
ReactDOM.render(
  <ReExtProvider splash={true} ReExtData={ReExtData}>
    <App />
  </ReExtProvider>,
  document.getElementById('root')
);

Example Application Code

Here’s a sample React application using ReExt with several user interface design components such as grids, labels, and buttons:

import React, { useState, useRef } from 'react';
import ReExt from '@gusmano/reext';
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={{ 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'
        style={{ height: 300 }}
        config={{
          title: 'grid',
          columns: [
            { text: 'Name', dataIndex: 'name', width: 200 },
            { text: 'Email', dataIndex: 'email', flex: 1 },
            { text: 'Phone', dataIndex: 'phone', width: 200 }
          ],
          data: [
            { name: 'Lisa', email: '[email protected]', phone: '555-111-1224' },
            { name: 'Bart', email: '[email protected]', phone: '555-222-1234' },
            { name: 'Homer', email: '[email protected]', phone: '555-333-1244' },
            { name: 'Marge', email: '[email protected]', phone: '555-444-1254' }
          ]
        }}
        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>
      <div style={{ flex: 1, padding: 20, border: '1px solid gray' }}>
        <ReExt xtype='label'
          config={{ html: 'initial text' }}
          ready={(cmp) => setLabelCmp(cmp)}
        />
        <ReExt xtype='label' config={{ html: labeltext }} />
      </div>
    </div>
  );    
};
export default App;

This example highlights how you can use JavaScript UI components and React JS components together effectively.

Why Choose ReExt?

ReExt makes your life easier if you want to use both React and Ext JS strengths. You don’t need to build everything from scratch. Just add Ext JS components straight to a React application and start using them.

It’s way easier and saves you a lot of hassle. No need to redo JavaScript components you already know and trust, especially if your project leans heavily on Ext JS UI components.

It just makes everything faster and less complicated. Plus, Ext JS components are known for being speedy and handling large data like a champ. With ReExt, you get those performance perks inside your React app without giving up React’s smooth flexibility and reactivity.

It really feels like having the best of both worlds, the solid, pre built UI components from Ext JS combined with the ease and power of React elements. Plus, you don’t have to pick one over the other.

ReExt lets you keep React and Ext JS up to date separately. So, you can enjoy React’s state management and clean user interface design components, while still using the rich, pre-built UI components from Ext JS.

It’s a smart way to mix and match your favorite JS UI components framework without compromise.

Tips for Using ReExt Smoothly in Your React Projects

If you’re adding ReExt to your React app, there are some simple things to keep in mind to make life easier:

• React works best with its declarative style. So, instead of doing things yourself, let React handle this. Let it take control of the rendering flow; it’s what it does best.
• If you try to change things in the DOM manually, it’s a complete mess. Trust me, it’ll break things or cause unexpected behavior.
• React itself can perform very nicely and efficiently with these things. That’s why using its built-in features keeps your app smooth and maintainable.
• Ext JS components are great, but don’t go crazy using tons of them all at once, especially if your app deals with big datasets. It’s tempting to load up on fancy charts and grids, but too many JavaScript web components can slow things down fast.

So, think ahead about how and when to load data. Lazy loading can really help if you’ve got complex views or heavy JavaScript UI components.

React has a tool for managing data and application behaviour, called hooks, like useState and useEffect. They are really helpful in syncing the React JS components and Ext JS parts. That way, your UI components work together nicely without any weird glitches.

And don’t forget, whether you’re picking a JavaScript component library or working with React UI component libraries, these tips help you get the best performance and a smoother user experience. It’s all about balance, clean structure, and knowing when to let the framework do the heavy lifting.

Conclusion

If you’re building a simple or complex app with React and want something smoother and more efficient, ReExt might be your new favorite tool. It combines the flexibility of React with a powerful set of pre-built UI components. So, instead of starting from scratch, you get a solid foundation right out of the box.
