Faser (favicon server) is a self-hosted, cached favicon server that returns an image for a domain or URL.
Please see the docker-compose.yml example below for reference. You can set the following environment variables:
| Variable | Description |
|---|---|
| FASER_LOG_LEVEL | debug, info, warn |
| FASER_CACHE_DIR | Sets the favicon cache directory. /app/cache inside the container volume. |
| FASER_CACHE_MAX_AGE | Sets the maximum time a favicon will be cached (in seconds). |
| FASER_CACHE_MAX_ENTRIES | Sets the maximum number of favicons stored (not including scaled images). |
| FASER_DEFAULT_FAVICON | Sets the default favicon path. default.svg inside the container volume. |
| FASER_DEFAULT_FAVICON_DIR | Sets the fallback favicon path. /app/static inside the container volume. |
| FASER_CORS_LOG_LEVEL | debug, info |
| FASER_CORS_ORIGINS | Sets the allowed origins (* by default). |
| FASER_SERVER_HOST | Sets the host ip:port (:8080 by default). |
| FASER_SERVER_WRITE_TIMEOUT | Sets the HTTP write timeout in seconds (5 by default). |
| FASER_SERVER_READ_TIMEOUT | Sets the HTTP read timeout in seconds (5 by default). |
| FASER_SERVER_TLS | true, false |
| FASER_SERVER_TLS_CERT | Path for the TLS certificate. |
| FASER_SERVER_TLS_KEY | Path for the TLS private key. |
Once you have the server up and running, you can make a request to it:
example.com/?url=github.com&size=64
This request will return the favicon for github.com scaled to a maximum of 64px width and height. The size parameter is optional. If you don't provide it, the maximum size will be returned. Make sure that you still set the maximum sizes on your end, as the favicon might not have the exact size you specified (if it's a svg for example).
In case the favicon cannot be downloaded, the default favicon is returned. You can also select a favicon if you know its filename by adding the fallback query parameter.
example.com/?url=github.com&size=64&fallback=my-favicon.svg
