Announcing Grafio: A High-Performance Graph Database

We're thrilled to announce the release of Grafio - a high-performance, TypeScript-native graph database built for modern applications.

What is Grafio?

Grafio is a lightweight, embeddable graph database that brings the power of graph data structures to JavaScript/TypeScript applications. With native Cypher query language support and pluggable storage backends, Grafio makes working with connected data simple and efficient.

Key Features

• Native Cypher Support - Write queries in Cypher, the same language used by Neo4j
• TypeScript First - Full type safety and excellent IDE support
• Pluggable Storage - Use in-memory for speed, or plug in Redis/MongoDB for persistence
• Powerful Traversals - Built-in graph traversal and path finding algorithms
• Lightweight - Zero dependencies, tree-shakable, works in Node.js and browsers

Getting Started

Install Grafio:

npm install grafio

Then create your first graph:

import { CypherEngine } from 'grafio';
import { InMemoryGraphFactory } from 'grafio/storage';

// Create graph via factory
const factory = new InMemoryGraphFactory();
const graph = factory.forGraph('social-network');
const cypher = new CypherEngine(graph);

// Adding social network
cypher.execute(`
    CREATE (a:Person {id: 'alice', name: 'Alice', age: 30}),
    CREATE (b:Person {id: 'bob', name: 'Bob', age: 25}),
    CREATE (c:Person {id: 'charlie', name: 'Charlie', age: 35})
`);
// Adding relationships
cypher.execute(`
  MATCH (a:Person {id: 'alice'}), (b:Person {id: 'bob'})
  CREATE (a)-[:KNOWS {since: 2020}]->(b)
`);
cypher.execute(`
  MATCH (b:Person {id: 'bob'}), (c:Person {id: 'charlie'})
  CREATE (b)-[:KNOWS {since: 2019}]->(c)
`);

// Querying the network
const friends = cypher.execute('MATCH (p:Person)-[:KNOWS]->(friend:Person) RETURN p.name as name, friend.name as friend');

/* Returns: 
    [
        {"name":"Alice","friend":"Bob"},
        {"name":"Bob","friend":"Charlie"}
    ]
*/
