@cairnkit/core

Framework-free engine for in-app product tours that fail the build instead of the user. Zero runtime dependencies.

npm i @cairnkit/core

Most people want @cairnkit/react and @cairnkit/ui instead — this package is the engine they are built on.

What is in here

• Anchors — a typed registry, the anchor() prop spreader, and resolution that prefers visible matches so one id works across breakpoints
• Flows — step definitions, five advance rules, and the resume / pause / handoff lifecycle for when users wander off the guided path
• Engine — an observable store and the route decision logic
• Events — a typed analytics schema

import { anchor, defineAnchors, defineFlow } from "@cairnkit/core";

export const anchors = defineAnchors({
  invite: { send: "invite.send" },
});

export const flow = defineFlow({
  id: "invite-candidate",
  version: 1,
  entryRoute: "/pipeline",
  steps: [{ anchor: anchors.invite.send, title: "Send it", body: "Nothing goes out until you click." }],
});
