WHAT DOES THIS PROJECT IMPLEMENT?

This project demonstrates the use of the following basic technologies:

• Caching(redis)
• JSON based API calls(Flask)
• Concurrent Network requests(concurrent futures)
• Base app logic(Python)
• Unit Testing(unittest)

Here, I implement a flask web app that serves html. All dependencies are specified in requirements.txt The service will be running at http://127.0.0.1:5000/.

Step 1

The app loads a form with some fields for ingesting input. The form also has a SUBMIT button. To keep the app simple, we do not worry about form validation or any styling.

Step 2

When the form is submitted, 2 HTTP POST requests are made in parallel to snaptravel,com and Hotels.com APIs with the following request body

{
  city : city_string_input,
  checkin : checkin_string_input,
  checkout : checkout_string_input,
  provider : 'snaptravel' OR 'retail'
}

The responses will be in json and each response will have an array of hotels and prices.

[{
  id : 12,
  hotel_name : 'Center Hilton',
  num_reviews : 209,
  address : '12 Wall Street, Very Large City',
  num_stars : 4,
  amenities : ['Wi-Fi', 'Parking'],
  image_url : 'https://images.trvl-media.com/hotels/1000000/20000/19600/19558/19558_410_b.jpg',
  price : 132.11
},
...
]

The app then caches these responses in the server, in whatever way that seems fit using redis.

Step 3

After both these calls have returned, we take only the hotels that appear in both the responses and return an html table with the data.
