interview-task-2

Technical test using Symfony 4, Doctrine, MySQL, Redis, RabbitMQ, Twilio and Vagrant.

Allows an SMS to be sent via a form.

Usage

• Install VirtualBox and Vagrant
• Create a file, .env.local, in the symfony directory. Add the following keys and appropriate values: TWILIO_ACCOUNT_SID, TWILIO_AUTH_TOKEN, TWILIO_SENDER_NUMBER, RECIPIENT_PHONE_NUMBER
• Navigate to the vagrant directory and run vagrant up
• To start the sms consumer, ssh into the interview-task-2 vagrant box (vagrant ssh interview-task-2), navigate to /vagrant/interview-task-2/symfony and run php bin/console rabbitmq:multiple-consumer sms
• To send a message, make a GET request (or navigate in your browser) to http://localhost:8000

Completed Functionality

• Send an SMS to any number using a GET request (Queues messages with RabbitMQ)
• Rate limit requests to 1 per 15 seconds (Uses Redis)
• Serve a page with a form to enter a message and phone number
• On submitting the form (via a send button), queue the message to be sent
• Validation of requests (limit sms body to 140 chars, limit recipient to UK mobile number)
• Store all messages sent (body, sender, timestamp)
• Serve a page with a list of all SMS messages sent by the system, ordered by newest first

To do

• Error handling
• Store & update the status of the SMS (queued, sent, failed). Note this will update after the initial message is sent (in progress)
• Create a user sign-up & login
• Restrict sending SMS to signed-in users
• Test it - read up on best practises for RabbitMQ & Rate limiting tests first
• Run the tests in Travis and display results in Github
