@cypher-anywhere/sqljs-adapter

Storage adapter backed by sql.js which provides an in-memory SQLite database compiled to WebAssembly.

Installation

npm install @cypher-anywhere/sqljs-adapter

Quick start

import { CypherEngine } from '@cypher-anywhere/core';
import { SqlJsAdapter } from '@cypher-anywhere/sqljs-adapter';

const adapter = new SqlJsAdapter({
  // start with no data
  dataset: { nodes: [], relationships: [] }
});

const engine = new CypherEngine({ adapter });

Cypher queries can create and query data once the adapter is initialised.

Loading initial JSON

You may also pass an initial dataset or datasetPath. The JSON shape matches the other adapters:

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

This data is loaded into the in-memory SQL database before the engine runs.
