Render-less container for ID generation
React made responsible
State container with the known past, present, and the future
Opinionated toolbox boilerplate to create Typescript React components
React hook which combines mouse and keyboard for a single hover event
🙊🙈🙉 - the best way to scope a scroll, or literally any other event.
Stateful fullpage.js inspired scrolling for React
Foldable section
Retain visual-regression observations across runs and answer churn, flakiness, reach and token-drift questions.
Announce what the code decided, so a test waits for the decision instead of guessing when it was made.
Add a source-aware visual observation to a Playwright test that already knows how to reach the state.
Pixel-tier contracts for Variance Authority: what a renderer and a store promise, and which policy a comparison ran under.
Run many Variance Authority subjects in one standing DOM world, and detect cross-pollution rather than prevent it.
Sense spacing, alignment, prominence and repetition inside one live interface, as evidence an agent can read.
Faster PNG decoding for Variance Authority through sharp, for runtimes that can load a native addon.
Record runtime scenarios as AAA state machines and assess variance across witnessed transitions.
Read React provenance from rendered DOM nodes: owner chains, props digests and portals, without importing the app’s React.
Which components and tests a source change reaches: test selection and impact analysis from a versioned index of a checkout.
A persistent Playwright harness and renderer for Variance Authority: one browser per run, documents turned into rasters.
A self-hosted HTTP history service for Variance Authority observations and approvals.
Capture a mounted DOM subject in a browserless Jest or Vitest process, then render and observe it later.
Carry the file and line that wrote a JSX element as far as the rendered DOM node.
Expose independently supplied observability evidence to an MCP client.
Read a TypeScript workspace API surface as data: every entrypoint a manifest opens and what each one exports, for release and breaking-change checks.
Hold what a running test suite is saying in a process an agent can ask, so a test in flight is something to look at rather than something to wait for.
Find the public name, signature, documentation and consumers of an exported TypeScript workspace symbol, over MCP.
Run a Variance Authority renderer or baseline store on the other side of an HTTP hop.
The Variance Authority format, rules, comparison, attribution and verdicts. Pure data in, pure data out, no DOM and no I/O.
The shape a Variance Authority run leaves behind, so a person, a pull request and an agent read one format.
Compare render documents or rasters and receive one Variance Authority observation, whatever produced the images.
Turn a built or already-served Storybook into Variance Authority subjects.
Turn pages your application already serves into Variance Authority subjects.
The address a process under test answers on, so what it reports reaches the run that started it and nothing is written down.
Record which DOM elements a test addresses and preserve their React attribution before the rendered tree moves.
Run the Variance Authority workflow from a project config: collect subjects, compare, render what moved, report, accept.
Extract a Variance Authority capture from a mounted element, under jsdom or a browser, with CSS applicability pruning.
A self-hosted review service for Variance Authority baselines, history and per-subject decisions.
Storybook index parsing, subject planning and a host-neutral preview driver.
Decode, compare and diff PNGs without a browser: two buffers in, a mask out.
Variance Authority baselines on a filesystem, in a plain directory or through git-LFS.
