react-native-android-sms-listener

react-native-android-sms-listener react-native-android-sms-listener

An utility that allows you to listen for incoming SMS messages.

Example

import SmsListener from 'react-native-android-sms-listener'
 
SmsListener.addListener(message => {
  console.info(message)
})

The contents of message object will be:

{
  originatingAddress: string,
  body: string
}

SmsListener#addListener returns a CancellableSubscription so if you want to stop listening for incoming SMS messages you can simply .remove it:

let subscription = SmsListener.addListener(...)
 
subscription.remove()
Example of using it for verification purposes:

...and if in your sign up process you have the phone number verification step which is done by sending a code via SMS to the specified phone, you might want to verify it automatically when the user receive it — pretty much like what Telegram or WhatsApp does:

let subscription = SmsListener.addListener(message => {
  let verificationCodeRegex = /Your verification code: ([\d]{6})/
 
  if (verificationCodeRegex.test(message.body)) {
    let verificationCode = message.body.match(verificationCodeRegex)[1]
 
    YourPhoneVerificationApi.verifyPhoneNumber(
      message.originatingAddress,
      verificationCode
    ).then(verifiedSuccessfully => {
      if (verifiedSuccessfully) {
        subscription.remove()
        return
      }
 
      if (__DEV__) {
        console.info(
          'Failed to verify phone `%s` using code `%s`',
          message.originatingAddress,
          verificationCode
        )
      }
    })
  }
})

If you're using Twilio or a similar third-party messaging service which you have a fixed phone number to deliver messages you might want to ensure that the message comes from your service by checking message.originatingAddress.
