MySMS Messenger

In this exercise you are requested to develop MySMS Messenger.

MySMS Messenger is a full stack web app allowing the end users to send SMS messages as well as displaying them.

• The frontend of the app should be written in Angular's latest stable version.
• The backend (API) of the app should be written in Ruby on Rails with a database of your choice.
• Sending an SMS should be done through Twilio API with a free account you've opened on your own (note they have a limit of a single phone number for free account, that's OK)

MySMS Messenger Wireframe

Functionality that we'd like the app to have:

1. You're able to send a message by talking to the backend API
2. The messages sent so far are stored in a DB that the backend manages
3. You're able to see the messages that were previously sent - the app should talk to the backend through a messages listing API endpoint
4. Only messages sent by the user's session ID cookie should be visible when calling the listing API

Bonus 1 - Add basic user authentication

Instead of using a session ID - add a user model to the backend.
Users should be able to provide a user name + password through the app to login and then also log out
Messages should be stored per user rather than session ID.

Note - use built in / well known GEMs to add support for that rather than implementing your own authentication (Always a bad practice).

Bonus 2 - Deploy The App

In this part of the exercise, you are requested to deploy MySMS Messenger.
End result would be a live demo of app that is fully functional.

Bonus 3 - webhooks

Add a reflection to the message cards showing that twilio successfully delivered the message:

Once done, please push your code to a public GitHub repo along with a link to the live demo of the app.
