Shared recurrence engine for parsing, querying, timezone-aware expansion, set composition, and text rendering.

@rrulenet/core provides the shared engine in the ecosystem. It is intended to be consumed by the public packages rather than directly by most applications.

Use @rrulenet/core when you are building on top of the engine itself. Use @rrulenet/rrule for the classic class-based compat API, and use @rrulenet/recurrence for the Temporal-first public API.

Install

npm install @rrulenet/core

Role in the Ecosystem

@rrulenet/core owns the shared recurrence engine:

• RFC-style parsing helpers
• timezone-aware occurrence expansion
• set algebra and querying
• text rendering primitives

Most applications should not import it directly. It is the package that powers the public APIs exposed by @rrulenet/rrule, @rrulenet/recurrence, and the workflows exposed through @rrulenet/cli.

Notes

• @rrulenet/core owns the engine implementation.
• @rrulenet/rrule and @rrulenet/recurrence are the public API façades.
• @rrulenet/cli should consume the public APIs rather than deep engine internals.
