Description

An easy way to track your page or project views ("hits") of any GitHub or online project.

Generate your own: hits.webklex.com

Table of Contents

Features
  • Serving over HTTPS (TLS) using your own certificates, or provisioned automatically using LetsEncrypt.org
  • HSTS ready to restrict your browser clients to always use HTTPS
  • Configurable read and write timeouts to avoid stale clients consuming server resources
  • Reverse proxy ready
  • Configurable CORS to restrict access to specific domains
  • Configurable api prefix to serve the API alongside other APIs on the same host
  • Optional round trip optimization by enabling TCP Fast Open
  • Integrated rate limit (quota) for your clients (per client IP) based on requests per time interval; several backends such as in-memory map (for single instance), or redis or memcache for distributed deployments are supported
Installation

Download and unpack a fitting pre-compiled binary or build a binary yourself by by following the build instructions.

Continue by configuring your application:

gohits -http=:8080 -gui gui -save

Open a browser and navigate to http://localhost:8080/ to verify everything is working.

Please take a look at the available options for further details.

If you're using LetsEncrypt.org to provision your TLS certificates, you have to listen for HTTPS on port 443. Following is an example of the server listening on 2 different ports: http (80) and https (443):

gohits \
    -http=:8080 \
    -https=:8443 \
    -hsts=max-age=31536000 \
    -letsencrypt \
    -letsencrypt-hosts=example.com \
    -gui gui \
    -save
$ cat conf/settings.config
{
    "HTTP": ":8080",
    "HTTPS": ":8443",
    "HSTS": "max-age=31536000",
    "LETSENCRYPT": true,
    "LETSENCRYPT_HOSTS": "example.com",
    ...

By default, HTTP/2 is enabled over HTTPS. You can disable by passing the -http2=false flag.

If the web server is running behind a reverse proxy or load balancer, you have to run it passing the -use-x-forwarded-for parameter and provide the X-Forwarded-For HTTP header in all requests. This is for the gohits web server be able to log the client IP, and to perform correctly identify new hits.

API

The API is served by endpoints that encode the response in different formats.

curl :8080/json/{username}/{repository}

Same semantics are available for the /xml/{username}/{repository} and /csv/{username}/{repository} endpoints.
