falkordblite

Embedded FalkorDB for Node.js/TypeScript. Zero-config graph database that runs locally (redis-server + FalkorDB module) and connects over a Unix socket.

Quick start

import { FalkorDB } from 'falkordblite';

const db = await FalkorDB.open();
await db.selectGraph('quickstart').query('RETURN 1');
await db.close();

Installation

npm install falkordblite

The package automatically installs pre-built Redis + FalkorDB binaries for your platform. No system dependencies required.

If you also want to connect to remote servers, install the upstream client:

npm install falkordb

Examples

See the examples/ directory:

• basic.ts - minimal usage
• persistence.ts - durable data with a path
• multiple-graphs.ts - isolated graphs in one DB
• migration.ts - 1-line change to remote
• graphrag-example.ts - use with GraphRAG tooling

API reference

FalkorDB.open(options?)

Create a new embedded FalkorDB instance. This resolves binaries, generates a redis.conf, starts a local redis-server process, and connects a falkordb client.

Returns: Promise<FalkorDB>

FalkorDB instance methods

• selectGraph(graphId: string): Graph
• list(): Promise<string[]>
• info(section?: string): Promise<unknown> (Redis INFO output)
• configGet(configKey: string): Promise<unknown>
• configSet(configKey: string, value: number | string): Promise<void>
• close(): Promise<void>

FalkorDB getters

• socketPath: string - Unix socket path for the embedded server
• pid: number | undefined - redis-server PID
• isRunning: boolean - whether the server is still alive

Graph API (from falkordb)

selectGraph() returns the exact Graph type from the falkordb package, so all graph methods (query, roQuery, delete, copy, explain, profile, slowLog, constraints, indexes, etc.) work the same. See the upstream client docs for details.

Advanced exports

The package also exports internal building blocks for advanced usage:

• ConfigGenerator, ServerManager, BinaryManager
• registerServer, unregisterServer

These are not required for normal usage but can help with custom embedding.

Configuration options

Option	Type	Default	Description
path	string	temp dir	Data directory for persistence. If set, periodic snapshots are enabled.
redisServerPath	string	auto	Custom redis-server binary path.
modulePath	string	auto	Custom FalkorDB module (.so) path.
maxMemory	string	unset	Redis maxmemory, e.g. "256mb".
logLevel	'debug' | 'verbose' | 'notice' | 'warning'	unset	Redis log level.
logFile	string	stdout	Redis log file path.
timeout	number	10000	Startup timeout in milliseconds.
additionalConfig	Record<string, string>	none	Extra redis.conf key/value pairs.
falkordbVersion	string	v4.16.3	FalkorDB module release tag to download.
inheritStdio	boolean	false	Pipe redis-server stdout/stderr to the parent.

Tip: use additionalConfig to set a TCP port (for external tools) by adding { port: '6379' }.

Migration guide (embedded -> remote)

Your graph code stays the same. Only the import and connection line changes:

// Embedded
import { FalkorDB } from 'falkordblite';
const db = await FalkorDB.open();

// Remote (falkordb-ts)
import { FalkorDB } from 'falkordb';
const db = await FalkorDB.connect({
  socket: { host: '127.0.0.1', port: 6379 },
});

Platform support

Platform	Status
Linux x64	✅ Fully supported (binaries included)
macOS arm64	✅ Fully supported (binaries included)
macOS x64	Use system redis-server + custom module path
Windows	Use WSL2 or a remote server
