Overview

GraphRAG-RS is a 5-crate Cargo workspace. You pick the entry point that fits your deployment.

Crate	Role
`graphrag-core`	Core library — all GraphRAG logic. Native + WASM (`rlib` + `cdylib`).
`graphrag-cli`	Turnkey TUI + CLI binary. In-process use of the core (no HTTP).
`graphrag-server`	Actix-web REST API with OpenAPI + optional Qdrant.
`graphrag-wasm`	Browser bindings (Voy vector store, WebLLM, ONNX).
`graphrag`	Wrapper meta-crate that re-exports `graphrag-core` for the hello-world experience.

The config-driven pipeline

The same code runs three ways, selected at runtime from Config — not at compile time:

Pattern-only — no LLM, regex extractor, < 10 ms per chunk. Config::default() works offline via hash-fallback embeddings.
LLM-enriched — Ollama with KV-cache reuse (keep_alive + dynamic num_ctx) for higher-quality entity and relationship extraction.
Hybrid — selective LLM stages over a fast base pipeline.

See How It Works for the full 7-stage pipeline.

Deployment options

Server — multi-tenant, GPU workloads, large corpora. Qdrant + Ollama. See graphrag-server.
WASM (client-side) — privacy-first, offline, zero infrastructure. Full pipeline in the browser with ONNX embeddings and WebLLM synthesis. See graphrag-wasm.
Embedded library — call graphrag-core directly from your Rust app.

Prerequisites

Rust 1.85+ (add the wasm32-unknown-unknown target for WASM builds).
Ollama (optional) for LLM-quality extraction / real embeddings: ollama pull nomic-embed-text.
Docker (optional) for the Qdrant vector database.
