Add TypeScript types for handlers

**Description**
Currently components lacks proper compression support.

**Proposed solution**
Add configurable compression with sensible defaults.

**Priority**: Low/Medium

First reconcile whether the intended change is TypeScript types for handlers or configurable compression for components; the title and description do not match. No files, tests, or entry points are named, so locate the relevant area and confirm the expected behavior and defaults before defining completion.
