@cypher-anywhere/json-adapter

In-memory adapter that stores graph data in a plain JavaScript object. It can be used for testing or small applications where persistence is not required.

Installation

npm install @cypher-anywhere/json-adapter

Using with the core engine

import { CypherEngine } from '@cypher-anywhere/core';
import { JsonAdapter } from '@cypher-anywhere/json-adapter';

const adapter = new JsonAdapter({
  // start with an empty graph
  dataset: { nodes: [], relationships: [] }
});

const engine = new CypherEngine({ adapter });

You can now create and query nodes and relationships using Cypher.

Loading initial data

Instead of starting empty you may provide dataset or datasetPath when creating the adapter. The JSON should look like this:

{
  "nodes": [
    { "id": 1, "labels": ["Person"], "properties": { "name": "Alice" } }
  ],
  "relationships": [
    { "id": 2, "type": "KNOWS", "startNode": 1, "endNode": 1, "properties": {} }
  ]
}

The data can then be modified with Cypher commands.
