Quick Start

Node.js

import { NeptuneClient, CreateDBClusterCommand } from '@aws-sdk/client-neptune';

const client = new NeptuneClient({
  endpoint: 'http://localhost:4566',
  region: 'us-east-1',
  credentials: { accessKeyId: 'test', secretAccessKey: 'test' },
});

await client.send(new CreateDBClusterCommand({
  DBClusterIdentifier: 'my-neptune-cluster',
  Engine: 'neptune',
}));

Python

import boto3

client = boto3.client('neptune',
    endpoint_url='http://localhost:4566',
    region_name='us-east-1',
    aws_access_key_id='test',
    aws_secret_access_key='test')

client.create_db_cluster(
    DBClusterIdentifier='my-neptune-cluster',
    Engine='neptune')

Configuration

cloudmock.yml

services:
  neptune:
    enabled: true

Known Differences from AWS

• No actual graph database is provisioned
• Gremlin and SPARQL endpoints are not available
• Snapshots are metadata-only
