@weaveworm/core

Framework-agnostic state machines and adapter contracts for AI-native UI patterns — the headless layer of weaveworm.

Zero runtime dependencies. Patterns speak only a normalized StreamEvent vocabulary (text-delta, reasoning-delta, tool-call, source, error, finish); adapters map any backend into them. That seam is what breaks SDK lock-in: swap the adapter, keep the UI.

import { createStreamMachine } from "@weaveworm/core";
import { createRawSSEAdapter } from "@weaveworm/core/adapters/raw-sse";

const adapter = createRawSSEAdapter({ url: "/api/chat" });

Adapters

Import	Backend
`@weaveworm/core/adapters/raw-sse`	Plain Server-Sent Events, no SDK
`@weaveworm/core/adapters/ai-sdk`	Vercel AI SDK
`@weaveworm/core/adapters/anthropic`	`@anthropic-ai/sdk`
`@weaveworm/core/adapters/mock`	Backend-free, for demos and tests

All adapters are structurally typed, so importing one never pulls its SDK into your bundle.

Bindings

React: @weaveworm/react

The logic lives here in portable TypeScript, so a binding for another framework is a bounded contribution.

Canon

Each pattern ships with codified best practices — the why, not just the code. See the weaveworm canon.
