@mekik/core

The realtime serving layer for ilmek graphs. Turns a running ilmek graph into a live conversation: streaming generative UI, tool traces, and durable, interactive human-in-the-loop over the mekik/1 wire protocol.

import { graph, channel, START, END } from "@ilmek/core";
import { mekik } from "@mekik/core";
import { serveWs } from "@mekik/ws";

const g = graph("refund")
    .channel("input", channel.lastWrite<string>(""))
    .channel("reply", channel.lastWrite<string>(""))
    .node("gate", async (s, ctx) => {
        mekik.ui(ctx, "order-card", { id: s.input });               // stream GenUI
        const ok = await mekik.approve<{ approved: boolean }>(       // pause for a human
            ctx,
            { title: `Refund ${s.input}?` },
            { ui: { component: "approval-form", props: { orderId: s.input } } },
        );
        return { reply: ok.approved ? "refunded" : "cancelled" };
    })
    .edge(START, "gate").edge("gate", END)
    .compile();

const app = mekik({ graph: g, reply: (s) => s.reply as string });
serveWs(app, { port: 8800, path: "/ws" });

The single mekik export is both the app factory (mekik({ graph })) and the node-authoring helpers (mekik.ui, mekik.tool, mekik.approve, …).
