Start Dev Graph

Start Dev Graph

Use this skill to run Dev Graph locally with the right subset of services.

Quickstart

• Full stack: powershell -ExecutionPolicy Bypass -File skills\\start-dev-graph\\scripts\\start_dev_graph.ps1 -Mode full
• Backend only: powershell -ExecutionPolicy Bypass -File skills\\start-dev-graph\\scripts\\start_dev_graph.ps1 -Mode backend

Workflow

1. Confirm repo root

• Require developer_graph/api.py and start_dev_graph.ps1.
• If missing, stop and ask for the correct working directory.

2. Decide the requested mode

• full: Neo4j + API + UI
• backend: Neo4j + API only
• services: just Neo4j
• frontend: only Dev Graph UI
• status: report what is running
• stop: stop Docker services and list any remaining processes

3. Docker preflight

• Check Docker CLI and Docker Compose:
  • docker version
  • docker compose version
• If Docker is installed but not running, say so and stop.

4. Start sequence

• full: run .\start_dev_graph.ps1
• backend:
  • docker compose up -d neo4j
  • uvicorn developer_graph.api:app --host 0.0.0.0 --port 8080 --reload
• services:
  • docker compose up -d neo4j
• frontend:
  • cd tools/dev-graph-ui then npm run dev

When launching uvicorn or npm, use new terminal windows so the main session stays responsive.

5. Status checks

• docker compose ps
• The script prints a port readiness summary (7474/7687/8080/3001).
• Report URLs:
  • http://localhost:3001
  • http://localhost:8080/docs
  • http://localhost:7474
  • http://localhost:3001/dev-graph/timeline
  • http://localhost:3001/dev-graph/structure

6. Stop sequence

• docker compose down
• Remind the user to close any uvicorn or npm windows still running.

Notes

• Docker Compose service name is neo4j in docker-compose.yml.
• The Windows batch script uses neo4j_db; do not copy that name here.
• Do not redirect uvicorn output to dev_graph_api.log in the repo root. The app writes the same file and will raise a permission error.
• The UI may choose port 3001 if 3000 is already in use; the script expects 3001.

Script

• Run: powershell -ExecutionPolicy Bypass -File skills\\start-dev-graph\\scripts\\start_dev_graph.ps1 -Mode full
• Backend only: -Mode backend
• Frontend + open page: -Mode frontend -Open -Page /dev-graph/structure
• Note: -Open is required to open a browser; -Page alone will not open anything.
