Creating an OtpSdk Instance

import OtpSdk from '@am92/otp'

const otpSdk = new OtpSdk()
export default otpSdk

If you wish to pass your custom 'config' to OtpSdk Class, then you can build it as follows:

import OtpSdk from '@am92/otp'

const config = {
  OTP_CONFIG: {
    OTP_LENGTH: 6,
    OTP_EXPIRY_IN_SECS: 300,
    OTP_GEN_HALT_IN_SECS: 30,
    OTP_GEN_LIMIT: 5,
    OTP_GEN_LIMIT_EXPIRY_IN_SEC: 1800,
    OTP_REGEN_LIMIT: 3,
    OTP_VAL_LIMIT: 3,
  },
  REDIS_CONFIG: {
    CONNECTION_CONFIG: {
      socket: {
        host: 'localhost',
        port: 6379,
        tls: true
      },
      password: 'password'
    },
    KEY_PREFIX: 'test'
  }
}

const otpSdk = new OtpSdk(config)
export default otpSdk
