The challenge is to create an API to shorten urls, in the style that TinyURL and bit.ly made popular.

1. The service must expose HTTP endpoints according to the definition below.
2. The service must be self contained, built on Python using Flask and able to be installed locally by following the steps you write in the README.
3. Write acceptance tests for your endpoints.
4. A data store is not required but it is a nice to have.

run

docker-compose build

to build the project.

Then

docker-compose up -d

System will be running on localhost:8000.

First Add some data with POST to the system and then try to navigate via short code.

take a look at your running container id via docker ps

then run docker exec -it <container-id> python tests.py

All responses must be encoded in JSON and have the appropriate Content-Type header

POST api/shorten
Content-Type: "application/json"

{
  "url": "http://example.com",
  "shortcode": "example"
}

201 Created
Content-Type: "application/json"

{
  "shortcode": :shortcode
}

A random shortcode is generated if none is requested, the generated short code has exactly 6 alpahnumeric characters and passes the following regexp: ^[0-9a-zA-Z_]{6}$.

GET api/:shortcode
Content-Type: "application/json"

302 response with the location header pointing to the shortened URL

HTTP/1.1 302 Found
Location: http://www.example.com

GET api/:shortcode/stats
Content-Type: "application/json"

200 OK
Content-Type: "application/json"
