ReExt in Action: Build Mobile Apps with React Component Library and Ext JS

ReExt combines React and Ext JS, or Extended JavaScript, to help build mobile apps with powerful user interface components out of the box. It saves time by letting you use ready-made tables, charts, and layouts directly in React, instead of writing custom code.The result is a fast, clean mobile app that works well on any screen. Without needing to stitch together multiple React libraries.

Making mobile apps today is more than just getting them to run. People want apps that look good, load fast, and work on any screen. A Google study says 53% of mobile users leave if a site takes more than 3 seconds to load. So yes, speed and smooth design matter a lot.

If you’re using React, you’re off to a solid start. It’s simple to work with and lots of people use it. But when you need things like tables, charts, or tricky layouts, it starts to get frustrating. React gives you the freedom, but not always the parts you need.

You end up doing a lot more work than you expected. You either write lots of custom code or mix in a React component library (or a few) that don’t always work well together.

That’s where ReExt, which is actually the combination of React and Ext JS, comes in. It blends React with Ext JS, an extended JavaScript framework, which has a ton of ready-to-use UI or user interface stuff. You can just plug Ext JS components right into your React project.

That saves you time and effort. Instead of fighting with layouts and controls, you can focus on building your app. ReExt keeps the React setup you like but adds the tools you need.

So, your app looks sharp and works fast, without all the extra work.

Using Ext JS Components in React for Mobile UI With a React Component Library

React’s Extended JavaScript components allow you to create more fluid mobile user interfaces without sacrificing flexibility. Grids, forms, tabs, and menus from Extended JavaScript drop in cleanly and work well with small screens. You still get the React feel, but with extra power and easier styling built in.

If you’re building with React and want a smoother mobile UI. You can pull in Ext JS components. They help speed things up without giving up flexibility.

It works well if you’re using a components-based setup.

Grids for Mobile Data Views

Start by importing the Ext JS grid into your React project. You can place it inside your layout using something like react-grid-layout. It works well on mobile and supports keyboard navigation for better accessibility.

Lists and Tabs

You can bring in Ext JS lists and tabs by wrapping them in React components. Keep the layout simple so it works on small screens. Use the theming system to style everything to match your design.

Forms and Validation

Forms from Ext JS can be used with your React state. Validation is built in, but keep the messages short and helpful. Support dark theme and make sure fields are easy to tap.

Navigation Menus

Menus are easy to plug in. You can customize them with your own styles. Keep them clean and clear so users don’t get lost.

You still get all the benefits of React frameworks while using parts of Ext JS. Things like a notifications system, smooth animations, or even a command palette can fit right in. It’s all about keeping things simple, flexible, and easy to use.

This setup works better than many other frameworks. It gives you strong customization options. And it still feels like a natural React component library.

Styling and Theming Your Mobile App

ReExt comes with built-in themes like Material, Triton, and Cupertino. So you don’t waste time styling everything from scratch. For utility-first designs, you can use Tailwind CSS or Syntactically Awesome Style Sheets for customisation.React tools like React Data Grid and React-grid-layout keep layouts responsive and easy to manage.

ReExt gives you a few built-in themes out of the box. Like Material, Triton, and Cupertino. These are great if you want something that just works.

Each one brings a different look and feel, so choose the one that feels right for your app. They’re built to be accessible out of the box, which means more people can use your app without you doing anything extra. That’s honestly a big plus.

Want more control? Use SASS, or known as Syntactically Awesome Style Sheets, to tweak colors, spacing, or whatever you like. In ReExt, it’s pretty simple.

And you don’t need to mess with a lot of code to match your brand. Tailwind CSS is easily integrated, too. So if you’re used to utility-first styling, that’s an option.

On mobile, small details matter. Think touch targets, font scaling, and spacing. You want buttons to be easy to tap, text to be readable on any screen, and layout to breathe a little.

That’s where things like function MyComponent help you build modular UIs. That responds well across devices using vanilla JS or even React component libraries.

Using tools like React-grid-layout or React Data Grid helps manage layouts and data views without extra bloat. Everything stays highly customizable, easy to manage, and quick to update. It’s all about creating apps you can easily customize, and that actually feel good to use.

Data Handling and State Management

Using Ext JS, or Extended JavaScript, with React can be tricky since both handle data differently and sync updates using hooks. For Representational State Transfer APIs or local data, skip Ext JS stores and just use Axios or fetch with React state.Keep things lean: use local storage or IndexedDB offline, and choose a clean setup with an intuitive Application Programming Interface.

Using Ext JS stores with React state can feel awkward at first. Ext JS manages data in its own way. But React wants control through its state.

To connect the two, listen for store updates and sync them to React using hooks. This keeps things clean and avoids extra logic. Your form components and other parts stay updated without extra work.

If you’re pulling from REST, also known as Representational State Transfer APIs or local data, skip the Ext JS store. Just fetch data using Axios or fetch, then drop it into useState. It’s faster, simpler, and easier to follow.

This also works well with most accessible UI components. They just need the data ready when the component renders. No need for anything heavy.

For offline use, local storage or IndexedDB can do the job. Write a small helper to save and load what you need. Keep it tight, only the necessary code.

Whatever React component library you use, Material UI, Bootstrap components, or something custom, keep it light. A clean setup with an intuitive API, known as Application Programming Interface, makes life easier. That’s key if you’re building an open source project or adding new features later.
