SMS OTP Verification on Node.js

This sample project demonstrates how to use Twilio's SMS Messaging APIs to verify application user's phone numbers.

Configure the sample application

To run the application, you'll need to gather your Twilio account credentials and configure them in a file named .env. To create this file from an example template, do the following in your Terminal.

cp .env.example .env

Open .env in your favorite text editor and configure the following values. You will need all of these values before you continue.

Config Value	Description
TWILIO_ACCOUNT_SID	Your primary Twilio account identifier - find this in the console here.
TWILIO_API_KEY	Used to authenticate - generate one here.
TWILIO_API_SECRET	Used to authenticate - just like the above, you'll get one here.
SENDING_PHONE_NUMBER	This phone number will be sending the SMS messages to the user. Either use a phone number you purchased through Twilio, or one you have verified with your account.
CLIENT_SECRET	It must match the server's config value. You can also disregard it from the code if needed, it's just a little bit of very basic security.

Run the sample application

Now that the application is configured, we need to install our dependencies from npm.

npm install

Now we should be all set! Run the application using the npm start command.

npm start

Your application should now be running at http://localhost:3000/.

Check your config values, and then make sure everything looks good.
