• Open Source: Fully auditable and customizable
• Pure Python: Easy to deploy and maintain

⚡ Quick Start for Spanner Graph

1. Run the following commands to start graphxr-database-proxy (requires uv, node.js)

git clone https://github.com/Kineviz/graphxr-database-proxy.git
cd graphxr-database-proxy
uv venv
source .venv/bin/activate # or .venv/bin/activate on Windows
uv pip install -e ".[ui]"
uv pip install -r requirements.txt
cd frontend && npm install && npm run build && cd -
graphxr-proxy --ui 

2. Visit http://localhost:9080/
3. Click "Create New Project"
4. Project Name: "Test"
5. Database Type: "Google Cloud Spanner"
6. Authentication Type: "Service Account"
7. Upload the credential file you exported from GCP Console or gcloud CLI. Export Instructions
8. Select "Instance ID" e.g. "demo"
9. Select "Database ID" e.g. "cymbal"
10. Select "Property Graph" e.g. "ECommerceGraph"
11. Click "Create"
12. For the new project, under Actions, copy the API URL. e.g. "http://localhost:9080/api/spanner/Test"
13. Go back to GraphXR's Create Project wizard and paste the API URL into GraphXR for a project with a "Database Proxy" database type.

Configure & Run

Option 1: Web UI (Recommended)

graphxr-proxy --ui

Open http://localhost:9080/admin for configuration

Option 2: Python Code with Service Account JSON

from graphxr_database_proxy import DatabaseProxy

proxy = DatabaseProxy()

service_account_json = {
    "type": "service_account",
    "project_id": "your-gcp-project-id",
    "private_key": "-----BEGIN PRIVATE KEY-----\\n...\\n-----END PRIVATE KEY-----\\n",
    "client_email": "[e-mail]",
    ...
}

project_id = proxy.add_project(
    project_name="project_name",
    database_type="spanner",
    project_id="gcp-project-id", 
    instance_id="spanner-instance-id",
    database_id="spanner-database-id",
    credentials=service_account_json,  
    graph_name="graph_name"  # Optional
)

proxy.start(
    host="0.0.0.0",     
    port=9080,          
    show_apis=True     
)

Option 3: Python Code with Google Cloud ADC

Your should have set up Google Application Default Credentials (ADC) on the machine running the proxy. See Google Cloud ADC Documentation.

from graphxr_database_proxy import DatabaseProxy
proxy = DatabaseProxy()

google_adc_credentials={
    "type": "google_ADC"
},  
 
project_id = proxy.add_project(
    project_name="project_name",
    database_type="spanner",
    project_id="gcp-project-id", 
    instance_id="spanner-instance-id",
    database_id="spanner-database-id",
    credentials=google_adc_credentials,  
    graph_name="graph_name"  # Optional
)

proxy.start(
    host="0.0.0.0",     
    port=9080,          
    show_apis=True     
)

🐳 Docker

docker run -d -p 9080:9080 \
--name graphxr-database-proxy \
-v ${HOME}/graphxr-database-proxy/config:/app/config \
kineviz/graphxr-database-proxy:latest

You can visit http://localhost:9080/admin for configuration after starting the container.
