### Features | ||
* Serving over HTTPS (TLS) using your own certificates, or provisioned automatically using [LetsEncrypt.org](https://letsencrypt.org) | ||
* [HSTS ready](https://en.wikipedia.org/wiki/HTTP_Strict_Transport_Security) 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](https://en.wikipedia.org/wiki/Cross-origin_resource_sharing) 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](https://en.wikipedia.org/wiki/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](https://github.com/webklex/gohits/releases) or build a binary | ||
yourself by by following the [build](#build) instructions. | ||
|
||
Continue by configuring your application: | ||
```bash | ||
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](#server-options) for further details. | ||
|
||
### Server Options | ||
To see all the available options, use the `-help` option: | ||
```bash | ||
gohits -help | ||
``` | ||

||
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): | ||
```bash | ||
gohits \ | ||
-http=:8080 \ | ||
-https=:8443 \ | ||
-hsts=max-age=31536000 \ | ||
-letsencrypt \ | ||
-letsencrypt-hosts=example.com \ | ||
-gui gui \ | ||
-save | ||
``` | ||
|
||
```bash | ||
$ 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. | ||
```bash | ||
curl :8080/json/{username}/{repository} | ||
``` | ||
Same semantics are available for the `/xml/{username}/{repository}` and `/csv/{username}/{repository}` endpoints. | ||
