I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

react canvas zoom drawing whiteboard

telva-core

Rendering and interaction engine primitives that power telva.

Install

npm i telva-core

Peer dependencies

react >= 16.8
react-dom >= 16.8

What you get

High-performance renderer components (Renderer, SVG/HTML containers, cursor infrastructure).
Unified input normalization for pointer, touch, wheel, and keyboard flows.
Geometry-aware hooks for bounds, selection, handle interaction, camera CSS, and shape events.
Utility/type foundations for editor-layer packages.

How it works internally

inputs.ts converts browser events into consistent editor-native TLPointerInfo / keyboard models.
components/Renderer composes canvas layers, shape trees, indicators, handles, and overlays.
hooks/* encapsulate cross-cutting behavior (positioning, zoom, bounds events, performance CSS).
TLShapeUtil provides a contract for shape-specific render/hit-test logic used by higher layers.
telva-intersect + telva-vec are used for spatial math and collision checks.

Dependency role in the ecosystem

telva-core is the engine layer between low-level geometry (telva-vec, telva-intersect) and full product integration (telva).
