isAvailable()

Use this function to determine whether NFCService functionality is available.

Syntax

import { getNFCService } from 'lightning/mobileCapabilities';
isAvailable(): Boolean

Parameters

None.

Returns

Usage

Use this function to disable or hide NFC operations on platforms where interacting with NFCs isn’t supported. For example:

handleGetNFCClick(event) {
    const myNFCService = getNFCService();
    if(myNFCService.isAvailable()) {
        // Perform NFC operations
    }
    else {
        // NFCService not available, or consuming app hasn’t implemented it
        // Not running on a device with NFC functionality, etc.
        // Handle with message, error, beep, and so on
    }
}
