graphcontrol

Graphcontrol

Graphcontrol is a OGM for Neo4j. It is intended for use in TypeScript, so you don't have to know any Cypher in order to query a Neo4j Database. This library isn't really suited for more complex Cypher Queries.

Installation

It can be installed via npm.

npm i graphcontrol

API

Setting up a Schema

const provider = new Neo4jProvider({
	url: "bolt://localhost:7687",
	username: "neo4j",
	password: "password"
});

type PersonProps = {
	name: string;
	age: number;
}

const Person = new Schema<PersonProps>(provider, "Person");

Relations can be defined the following way:

const relations = [{
	id: "car", //id to reference by
	schema: "Car", //label of the targeted Schema
	label: "OWNS", //relation label, e.g. ()-[:OWNS]->()
	direction: "to" //relation direction
}];
const PersonWithRelations = new Schema<PersonProps>(provider, "Person", relations);

getting nodes of a Schema

//all Nodes
await Person.getNodes();

//Person by Name
await Person.getNodes({where: {name: "John"}});

//find People named John and optionally their blue car(s)
await Person.getNodes({
    where: {name: "John"},
    relations: [{
	    id: "car",
	    where: {color: "blue"}
    }]
});
