Flight Aggregator

The goal of the api is to get every flight to a destination and sort it by : - price, - departure date - travel time

exercices :

• create a server (http.Server)
• set 2 routes (http.ServeMux):
  • GET /health : to verify the healthiness of the server
    • set the status response to 200 : w.WriteHeader(http.StatusCreated)
  • GET /flight.
• try to get the data of both apis from the server (client requests).
  • transform the data into structs (json.NewDecoder)
  • and organize the code to process the data in 2 repositories and extract the it using the same interface.
• return the flights ordered by price
• now you want to sort by price, time_travel or departure_date :
  • pass this information by query/params or body,
  • create the algorithms,
  • verify the output
• Create tests for :
  • your sorting algorithms,
  • your flight service :
    • mock the repositories to make the tests.

to help you

pre-setup

• install Docker Compose and start the project with: docker compose up
• air is setup to auto reload the project on every modification !
• a make file is here to run the tests with gotestsum :
  • install it with : go install gotest.tools/gotestsum@latest

Run the base project:

• docker compose build
• docker compose up

test

• make test

access the apis :

• j-server1 :
  • docker : http://j-server1:4001
  • localhost : http://localhost:4001
• j-server2 :
  • docker : http://j-server2:4001
  • localhost : http://localhost:4001

startup :

• use the Viper library Link Text,
• get every env variables with : viper.AutomaticEnv()
• then select with : viper.Get("MY_VAR")

tests :

• use Testify : Link Text
