DrivineSplash

drivine.org

Drivine is a graph database client for Node.js and TypeScript. It was created with the following design goals:

  • Support multiple graph databases (simultaneously, if you wish). Currently AgensGraph and Neo4j (or other BOLT compatible graph DBs).
  • Scale to hundreds and thousands of transactions per second, without compromising architectural integrity.

With regards to the second point on scaleability, let's break that down into component facets.

Features


Quick Start

Follow the Quick Start section in our User Guide or clone the sample app and use it as a starter template.

Start creating repositories like the one below.

@Injectable()
export class RouteRepository {
    constructor(
        @InjectPersistenceManager() readonly persistenceManager: PersistenceManager,
        @InjectCypher('@/traffic/routesBetween') readonly routesBetween: CypherStatement) {
    }

    @Transactional() // Has default Propagation.REQUIRED - partipicate in a current txn, or start one.
    public async findFastestBetween(start: string, destination: string): Promise<Route> {
        return this.persistenceManager.getOne(
            new QuerySpecification<Route>()
                .withStatement(this.routesBetween)
                .bind([start, destination])
                .limit(1)
                .transform(Route)
        );
    }
}

Example Applications

If you use Drivine and your code is public, feel free to make PR and add yourself to the list.

Quick Start Template

Clone the official sample app and start hacking.

Repository: github.com/liberation-data/drivine-inspiration

This sample is a basic starter template, with some tutorials. It has some endpoints for traffic routing, movies/films and other typical use-cases. Rather than start from scratch, choose the one that closely matches yours, and modify.

SlackMap

New version of slackmap.com is full rewrite with technology update. The OrientDB was replaced with Neo4j and we choose Drivine as the way to work with the database.

Check out how Drivine supports Neo4j in Full Stack JavaScript App using Angular + Nest + Nx Workspace Monorepo.

Repository: github.com/SlackMap/slackmap

  • master branch - not released yet
  • develop branch - has all the current work

About

Drivine was created by Jasper Blues (that's me), who is also the creator of a popular iOS library called Typhoon, which is included in thousands of iOS apps including Audible.com, AMEX, Etihad Airlines, Singapore Airlines and others.

This library is based on an architecture that was put in place for MSTS, after the company signed several Fortune 100 clients and needed to scale their payment service. The result was not only an improved architecture, but response times improved dramatically - from just under 2000ms seconds to around 63ms.

The ideas were ruminated upon while building Vampr - a growing social network for musicans that needs to serve hundreds of transactions per second. Clean architecture and performance are often competing concerns, so how would one go about getting the best of both worlds?

Drivine shows that it is not necessary to forego clean architecture in order to achieve scaleability goals.

Have you seen the light?

Drivine is a non-profit, community driven project. We only ask that if you've found it useful to star us on Github or send a tweet mentioning us (@doctor_cerulean). If you've written a Drivine related blog or tutorial, or published a new Drivine-powered app, we'd certainly be happy to hear about that too.

Drivine is sponsored and led by Liberation Data with contributions from around the world.
