Courier OTP

Custom OTP package for sending OTP via SMS and Email and verifying OTP. This package is built on top of Courier and Redis.

Installation

Using npm:

$ npm install --save courier-otp

Using yarn:

$ yarn add courier-otp

Usage

To use this package, you need to have a Courier account and a Redis server.

IMPORTANT: In your Courier account, you need to create a new template with the {otp} variable. This variable will be replaced with the OTP code. Otherwise, users won't receive the OTP code.

const { CourierOtp } = require('courier-otp')

const main = async () => {
  const courierOtp = new CourierOtp({
    redisUrl: '<redis-url>',
    courierApiKey: '<courier-api-key>',
    courierTemplateId: '<courier-template-id>',
  })
  // send otp
  const result = await courierOtp.sendOtp({
    to: '[email protected]',
    type: 'email',
  })
  console.log(result)
  // verify otp
  const verifyResult = await courierOtp.verifyOtp({
    to: '[email protected]',
    type: 'email',
    otp: '123456',
  })
  console.log(verifyResult)
}
