Dynamic Pipeline: Mutable Method‑Chaining for Real‑Time Processing

DEV Community •
×

A developer tackling real‑time stroke stabilization in a drawing app stumbled on a design gap. He needed a method‑chaining system that could add, remove, and update processing steps on the fly while staying readable. He dubbed this the Dynamic Pipeline pattern to streamline user experience and performance today.

The pattern mirrors classic pipelines but adds true runtime mutability. Unlike a Builder that locks configuration after build, or a Decorator that hard‑wires wrappers, the Dynamic Pipeline lets developers tweak the chain without rebuilding. This flexibility is vital when user settings shift mid‑session and preserve performance integrity.

In practice, the author applied the model to a StabilizedPointer that chains noise, Kalman, and Gaussian filters. UI changes trigger update calls, while high‑velocity strokes trigger remove of heavy filters. The chain remains executable at all times, eliminating costly re‑initialization for smooth user experience and real‑time responsiveness today.

The concept sits between Middleware and RxJS pipe, offering a mutable, order‑sensitive chain that can be cached for speed. Future work could formalize naming, benchmark performance, and explore unique‑ID tracking for duplicate steps. For now, the pattern invites feedback from the dev community to refine its practical applications.
