Add TypeScript types for parsers

**Description**
Currently data lacks proper monitoring support.

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

**Priority**: Low/Medium

Start by locating the parser entry points and any existing TypeScript type declarations. Reconcile the title's request for parser types with the body’s separate monitoring proposal before coding. The issue is done only when the intended scope is clarified and the agreed types or monitoring behavior are covered by the project’s relevant checks.
