Usage

Most of the functions detailed on the official documentation were implemented on this bridge. Here is some examples of each one of them.

import RNJuno from 'react-native-juno';

// You need to initialize the SDK before using the card hash method.
// The first parameter is your public key. This can be null on Android since it's already declared on the Manifest file.
// The second parameter is whether to run it on production or Sandbox. TRUE for production, FALSE for sandbox.
RNJuno.initialize("AC2261A2ECC7FD90D205502092571F5C1C0831935E35073AA95AEBEB68D7E5C5", true);

// This function returns a hash for the credit card informed.
// The first parameter is the Credit Card Number.
// The second parameter is the Holders Name.
// The third parameter is the Security Code.
// The fourth parameter is the Expiration Month.
// The fifth parameter is the Expiration Year.
// The sixth parameter is a callback function, containing the error message as the first parameter (String) and the hash as the second parameter (String).
RNJuno.getCardHash("5362682003164890", "Rafael Althaus", "123", "01", "2025", (error, data) => {
      if (error) {
        console.log("ERROR: " + error);
      } else {
        console.log("HASH: " + data);
      }
});

// Returns if the card number is valid.
// The first parameter is the card number.
// The second parameter is a callback function informing if the number is valid as TRUE of FALSE.
RNJuno.isValidCardNumber("5362682003164890", (data) => {
      console.log("VALID CARD NUMBER: " + data);
});

// Returns if the expire date is valid.
// The first parameter is the month number.
// The second parameter is the year number.
// The third parameter is a callback function informing if the date is valid as TRUE of FALSE.
RNJuno.isValidExpireDate("01", "2025", (data) => {
      console.log("VALID EXPIRE DATE: " + data);
});

// Returns if the security code is valid.
// The first parameter is the security code.
// The second parameter is the card number.
// The third parameter is a callback function informing if the security code is valid as TRUE of FALSE.
RNJuno.isValidSecurityCode("123", "5362682003164890", (data) => {
      console.log("VALID SECURITY CODE: " + data);
});

Known issues

• I wasn't able to implement the getCardType function because it was declared as private on the SDK;
• We currently need to declare retrofit2 as a dependency is this project since it's needed in the SDK and it's not declared in it;
• We're not able to set the public token dynamically on init in Android since the Android SDK only gets the token from the Manifest meta-data. We would really like to have an option to pass the token as a parameter in the initialize function in the future.
