Introduction

A counting service for PV and UV (based on Golang and Redis)

1. Why do this

I write a personal website: https://plantree.me, to archive my blogs. In the beginning, I used the visitor-badge service to show the number of visitors of each page. However, I found some drawbacks:

1. The service is not robust enough, which will limit the request when the QPS is too high.
2. This service is just designed for generating badge, and the data service behind is countapi. Unfortunately, it just provide limited interfaces and services, which could not satisfy my need.

I need a service that contains these functions:

1. Count service and badge generator service are deployed independently, and count service just provide data service. BTW, source code about badge generator service will be put in visitor-badge.
2. Count service could support PV(Page-Views) and UV(Unique-Visitors).
3. Count service could support reset/update manually, with secret to avoid malicious tampering.

2. counter vs countapi vs visitor-badge/hit-counter

	counter	countapi	visitor-badge/hit-counter
Service	just count	just count	hybrid count and badge generator, but not easy to get the data
Open Source	✅	❌	✅
Self Deployment	easy	difficult	medium
Features	read/write, with secret	read/write, without secret	read only
