Code knowledge graph for Claude Code & AI coding agents — index TypeScript, Python, NestJS, FastAPI, React into Neo4j and query architecture in Cypher. Note: v0.2.0 is deprecated, use 0.1.x.

codegraph

Map a TypeScript codebase into Neo4j with NestJS + React awareness, then query it.

Quick start

cd codegraph

# 1. Python env
python3 -m venv .venv
.venv/bin/pip install -r requirements.txt

# 2. Neo4j
docker compose up -d
# Browser UI:  http://localhost:7475   (neo4j / codegraph123)
# Bolt:        bolt://localhost:7688

# 3. Index easy-builder
.venv/bin/python -m codegraph.cli index /home/edouard-gouilliard/easy-builder

# 4. Validate
.venv/bin/python -m codegraph.cli validate /home/edouard-gouilliard/easy-builder

# 5. Ad-hoc query
.venv/bin/python -m codegraph.cli query "MATCH (e:Endpoint) RETURN e.method, e.path LIMIT 10"

See queries.md for example queries.
