    environment:
      # replace these env variables with your twilio account values
      TWILIO_ACCOUNT_SID: YOUR-TWILIO-ACCOUNT-SID-HERE

  5. Install the dependencies required by the service

    npm i --only=prod
    
  6. Deploy the service

    serverless deploy
    
  7. Invoke the function and send an SMS message

    Update the to phone number the event.json file and message to send in the SMS

    Then invoke the function with the serverless CLI. Set the --path event.json so the function knows where to send the SMS.

    serverless invoke -f sendText --path event.json
    
  8. (Optional) Deploy the front-end application

Update the API_ENDPOINT variable in the /frontend/index.html file and deploy the /frontend folder to a static host of your choice.

We recommend S3, netlify, or surge.sh for quick and easy static site hosting.
