React Native wrapper for Android's SMS User Consent API, ready to use in React Native apps with minimum effort. The purpose of SMS User Consent API is to provide one-tap auto-filling of SMS verification codes.
SMS User Consent API exists only on Android, so this package is Android-only. Calling this package's APIs on iOS is no-op.
If you want auto-filling on iOS, textContentType="oneTimeCode" for TextInput is the way to go. Basically, this is the only way for iOS.
Install the package:
yarn add @eabdullazyanov/react-native-sms-user-consent
or
npm install @eabdullazyanov/react-native-sms-user-consent
import React, { useEffect, useState } from 'react';
import { TextInput } from 'react-native';
import { useSmsUserConsent } from '@eabdullazyanov/react-native-sms-user-consent';
const Example = () => {
const [code, setCode] = useState();
const retrievedCode = useSmsUserConsent();
useEffect(() => {
if (retrievedCode) setCode(retrievedCode);
}, [retrievedCode]);
return <TextInput value={code} onChangeText={setCode} />;
};In the example we use a controlled TextInput for the code entry. retrievedCode equals to the empty string initially, and whenever an SMS is handled retrievedCode receives the code from it. We use the useEffect to update the input value when an SMS is handled.
Set the length of the validation code:
const retrievedCode = useSmsUserConsent(4);
// e.g. code = 1234Provide a custom regular expression:
const retrievedCode = useSmsUserConsent('[A-Z0-9]{5}');
// e.g. code = A12B3useSmsUserConsent(config: number | string): stringReact hook that starts SMS handling and provides the received code as its return value, which is the empty string initially. Stops handling SMS messages on unmount. Uses startSmsHandling and retrieveVerificationCode internally.
This hook is the way to go in most cases. Alternatively, you can use startSmsHandling and retrieveVerificationCode directly if dealing with something that is not a functional component or you need some more flexibility.
On iOS it just returns the empty string, so no additional code to handle iOS is needed.
Accepts an optional config parameter. In case if it's a number, it defines the length of the code. In case if it is a string, it defines a custom RegExp to parse the code.
startSmsHandling(onSmsReceived: (event: {sms?: string}) => void): (
stopSmsHandling(): void
)Starts the native SMS listener that will show the SMS User Consent system prompt. If the user allowed reading the SMS, then the onSmsReceived callback is called. onSmsReceived receives the event object containing the SMS.
Returns stopSmsHandling function that stops showing the system prompt and stops SMS handling.
retrieveVerificationCode(sms: string, config: number | string): string | nullRetrieves the verification code from an SMS if there is any.
Accepts an optional config parameter. In case if it's a number, it defines the length of the code. In case if it is a string, it defines a custom RegExp to parse the code.
You can import the whole API as one object if you prefer
import SmsUserConsent from 'react-native-sms-user-consent';
// ...
SmsUserConsent.useSmsUserConsent();
