How to build ionic apps with React?

Estimated read time 3 min read

Ionic is a popular open-source framework for building cross-platform mobile apps using web technologies like HTML, CSS, and JavaScript. Ionic supports several front-end frameworks, including React. Here’s how you can build Ionic apps with React:

  1. Set up a new Ionic project: You can use the ionic command-line interface (CLI) to create a new Ionic project. Open a terminal window and run the following command:
ionic start my-app react

This will create a new Ionic project using the React framework in a folder called my-app.

  1. Create pages and components: In Ionic, each screen or view is called a page, and each reusable element is called a component. You can create new pages and components using the ionic generate command. For example, to create a new page called AboutPage, run the following command:
ionic generate page About

This will create a new folder called about in the src/app directory with the files for the AboutPage component.

  1. Add routing: In Ionic, you can use the IonRouterOutlet and IonRoute components to set up your app’s routing. Add the following code to your App.tsx file to set up basic routing:
import React from 'react';
import { BrowserRouter as Router, Route } from 'react-router-dom';
import { IonApp, IonRouterOutlet } from '@ionic/react';
import { IonReactRouter } from '@ionic/react-router';

import HomePage from './pages/HomePage';
import AboutPage from './pages/AboutPage';

function App() {
  return (
    <IonApp>
      <IonReactRouter>
        <IonRouterOutlet>
          <Route exact path="/" component={HomePage} />
          <Route exact path="/about" component={AboutPage} />
        </IonRouterOutlet>
      </IonReactRouter>
    </IonApp>
  );
}

export default App;

This sets up two routes: one for the home page and one for the about page. You can add more routes as needed.

  1. Add Ionic components: Ionic provides a rich set of UI components that you can use in your React app. You can import these components from the @ionic/react library and use them in your pages and components. For example, to add a button to your HomePage, add the following code:
import React from 'react';
import { IonButton } from '@ionic/react';

function HomePage() {
  return (
    <div>
      <h1>Welcome to my app</h1>
      <IonButton>Get started</IonButton>
    </div>
  );
}

export default HomePage;

This adds an IonButton component to the HomePage with the text “Get started”.

  1. Run your app: You can run your Ionic app using the ionic serve command. This will start a development server and open your app in a web browser. You can also use the ionic build command to build your app for deployment to app stores.

These are the basic steps for building Ionic apps with React. You can add more pages, components, and features to your app as needed. Ionic also provides features like native APIs, theming, and more.
