Full-stack Take Home Exercise

Task

Create a simple web-app to lookup info for a text message.

The application should take a phone number and message string, and then send that data to a backend for analysis.

It should then display the following info:

• The matched Country, Region, Operator, and Prefix
• Message body with any urls highlighted and clickable
  ​ A sample dataset of country and operators prefixes is here for Canada, all numbers start with 1 ​ When matching a number to the prefix the application should select the record with the longest matching prefix from the supplied sample data set, for example ​ Given a phone number 14373293504 and a set of prefixes ​

  {"prefix": 1, "operator": "", "country_code": 1, "region": "", "country": "USA"},  
  {"prefix": 1, "operator": "", "country_code": 1, "region": "", "country": "Canada"},  
  {"prefix": 143, "operator": "", "country_code": 1, "region": "", "country": "Canada"},
  {"prefix": 1437, "operator": "", "country_code": 1, "region": "Ontario", "country": "Canada"},
  {"prefix": 1437329, "operator": "Lucky Mobile", "country_code": 1, "region": "Ontario", "country": "Canada"}
  {"prefix": 14372, "operator": "", "country_code": 1, "region": "Ontario", "country": "Canada"}
  

  ​ The application should select the record with prefix 1437329

User story

• As a user I can input a phone number and message string into the app
• I then see the country, region, operator and prefix of the phone number
• If the message contained a URL, I can click a link in the message to open the site

Technical Requirements

• React is prefered but not mandatory
• We also like Typescript
• Use any libraries
• The backend should provide a single RESTful endpoint or GraphQL edge to analyse messages (we use Python & Golang, but feel free to implement in your preferred language)
• Please write any tests you deem appropriate
• Write a docker-compose.yml to run the application (we'll run docker-compose up)

Notes

We don't need you provide a totally polished submission, your time is valuable! if something isn't perfect or you need to reduce the scope for any reason you're welcome to just talk to us about how you would improve your solution given more time.
