log-analyzer

This project implements a command-line interface (CLI) program that analyzes cookie logs in CSV format to identify the most active cookie for a specific date.

Running the Project

Using Makefile

1. Use make install to install the dependencies
2. Use make build to build the most_active_cookie binary
3. Run ./most_active_cookie cookie_log.csv -d 2018-12-09 to run the program
4. Opt: Use make run_cli ARGS="<csv_file_path> -d <date>, replacing <csv_file_path> with the path to your CSV file and <date> with the date in YYYY-MM-DD format.

Developing locally

1. Use make install to install the dependencies
2. Execute go run cmd/main.go cmd/cli.go cookie_log.csv -d 2018-12-09 to run the project without building

Run test

1. Use make test to run the testcases
2. Use make coverage to check the coverage for the files

Note

• The Server Implementation isn't needed but good to have (The project uses gin framework)
• The files that have (Opt) in the above tree are optional and are of server impl files
• The testcase coverage for the base business logic is 100%
• The project can be run as docker container as well but need to change the args in dockerfile
• The project uses Domain-Driven Design (DDD) approach for designing the software
