NativeScript + React

First, register the component before any of your React NativeScript app renders. A good place to put this code is in your entrypoint file (which may be called src/app.ts or similar), before the ReactNativeScript.start function is called. Here's how to install it:

import { registerTabNavigationBase } from '@nativescript-community/ui-material-core/tab-navigation-base/react';
import { registerTabs } from '@nativescript-community/ui-material-tabs/react';

registerTabNavigationBase();
registerTabs();

Normally it would be best to use this component via the tabNavigatorFactory() API exported by React NativeScript Navigation, as it makes nested navigation easy, but here's how to use it directly:

import * as React from 'react';

export function Tabs() {
    const [selectedIndex, setSelectedIndex] = React.useState(0);

    return (
        <tabs
            selectedIndex={selectedIndex}
            onSelectedIndexChanged={(args) => {
                setSelectedIndex(args.newIndex);
            }}
            style={{ backgroundColor: 'orange' }}
        >
            {/* The bottomTab UI is created via tabStrip (the container) and tabStripItem (for each tab) */}
            <tabStrip nodeRole="tabStrip" style={{ backgroundColor: 'red' }}>
                <tabStripItem nodeRole="items">
                    <label nodeRole="label">Home</label>
                    <image nodeRole="image" src="font://&#xf015;" className="fas" />
                </tabStripItem>
                <tabStripItem nodeRole="items">
                    <label nodeRole="label">Account</label>
                    <image nodeRole="image" src="font://&#xf007;" className="fas" />
                </tabStripItem>
                <tabStripItem nodeRole="items">
                    <label nodeRole="label">Search</label>
                    <image nodeRole="image" src="font://&#xf00e;" className="fas" />
                </tabStripItem>
            </tabStrip>

            {/* The number of tabContentItem components should corespond to the number of TabStripItem components */}
            <tabContentItem nodeRole="items">
                <gridLayout style={{ backgroundColor: 'blue' }}>
                    <label style={{ color: 'white' }}>Home Page</label>
                </gridLayout>
            </tabContentItem>
            <tabContentItem nodeRole="items">
                <gridLayout style={{ backgroundColor: 'cyan' }}>
                    <label style={{ color: 'black' }}>Account Page</label>
                </gridLayout>
            </tabContentItem>
            <tabContentItem nodeRole="items">
                <gridLayout style={{ backgroundColor: 'magenta' }}>
                    <label style={{ color: 'black' }}>Search Page</label>
                </gridLayout>
            </tabContentItem>
        </tabs>
    );
}

Troubleshooting

If you see an error like this when writing e.g. <tabs> into your JSX:

Property 'tabs' does not exist on type 'JSX.IntrinsicElements'.ts(2339)

Make sure that you have:

  1. Installed the react-nativescript npm module.
  2. Installed the @types/react npm module, strictly with the exact version provided in the React NativeScript starter template.
  3. Run the postinstall script that comes with the React NativeScript template – npm run postinstall – to patch @types/react.
  4. Registered the component as described above (i.e. import and run the registerTabNavigationBase() and registerTabs() methods).
  5. If using Visual Studio Code, option-click the import @nativescript-community/ui-material-tabs/react to jump to the file; opening the file will force it to load its provided typings.
