A basic Web Analytics API implemented using Go and Redis.
The API lets a site make POST requests to log page hits to Redis. And GET requests by users to get a count of hits logged between two dates or a count of unique visits, and get JSON responses back:
Log a hit
Get all visits to my site between any two arbitrary start and end times
Get all visits to a particular page on my site between any two arbitrary start and end times
Get all visits to my site by a particular referer between any two arbitrary start and end times
Get all visits to a particular page on my site by a particular referer between any two arbitrary start and end times
- GET: http://localhost:8080/getpageviews?s=1528329600&e=1528502399&ref=instagram.com&path=/index.html
Get Daily, Monthly, and Yearly unique visitors to my site given a date
A detailed screen cast of getting the app up and running and a detailed code walkthrough:
- gomodule/redigo: Go client for Redis (https://github.com/gomodule/redigo)
- gorilla/mux: Go request router (https://github.com/gorilla/mux)
- unrolled/render: Go package for easily rendering JSON, among other formats (https://github.com/unrolled/render)
- Transactions: (https://redis.io/topics/transactions)
- Hashes, Sorted Sets, and Hyperloglog: (https://redis.io/topics/data-types)
- Install Go
- Install Redis and have it running locally at the default port 6379
- Install redis-commander using npm
- cd into the project directory and run:
go run main.go - Start making POST & GET requests
- Add tests
- Easily able to add more dimensions to the app beyond referer and path
- Change the getpageviews GET call to accept date format of YYYY/MM/DD, instead of UNIX_TIMESTAMP
