The Knowledge Graph for TypeScript

import { defineNode, defineEdge, defineGraph, createStore } from "@nicia-ai/typegraph";
import { z } from "zod";

// 1. Define your ontology
const Person = defineNode("Person", {
  schema: z.object({ name: z.string(), role: z.string() })
});
const Project = defineNode("Project", {
  schema: z.object({ name: z.string(), status: z.string() })
});
const worksOn = defineEdge("worksOn");

const graph = defineGraph({
  id: "my_app",
  nodes: { Person: { type: Person }, Project: { type: Project } },
  edges: { worksOn: { type: worksOn, from: [Person], to: [Project] } }
});

// 2. Query with full type safety
const results = await store.query()
  .from("Person", "p")
  .whereNode("p", p => p.role.eq("Engineer"))
  .traverse("worksOn", "e")
  .to("Project", "proj")
  .select(ctx => ({ person: ctx.p.name, project: ctx.proj.name }))
  .execute();
