# Architecture
|
|
|
|
### Overview
|
|
|
|
BitTorrent clients send Announce and Scrape requests to a _Frontend_.
|
|
|
|
Frontends parse requests and write responses for
|
|
the particular protocol they implement.
|
|
|
|
The _TrackerLogic_ interface is used to generate responses for requests and
|
|
optionally perform a task after responding to a client.
|
|
|
|
A configurable chain of _PreHook_ and _PostHook_ middleware is
|
|
used to construct an instance of TrackerLogic.
|
|
|
|
PreHooks are middleware that are executed before the response has been
|
|
written. After all PreHooks have executed, any missing response fields that are required are filled by reading out of
|
|
the configured implementation of the _Storage_ interface.
|
|
|
|
PostHooks are asynchronous tasks that occur after a response
|
|
has been delivered to the client. Because they are unnecessary to for generating a response, updates to the Storage for
|
|
a particular request are done asynchronously in a PostHook.
