# Helpers

> Overview of ByteKit helper modules — environment, transport, caching, crypto, eventing, polling, and more.

## What lives here

These modules cover the rest of the public package surface: runtime helpers, transport utilities, caching, crypto, eventing, URL tools, and polling. Each has a focused entrypoint — import only what you need.
