An object representing a single ArangoDB database. All arangojs collections, cursors, analyzers and so on are linked to a Database object.

Hierarchy

  • Database

Constructors

  • Creates a new Database instance with its own connection pool.

    See also database.

    Example

    const db = new Database({
    url: "http://127.0.0.1:8529",
    databaseName: "my_database",
    auth: { username: "admin", password: "hunter2" },
    });

    Parameters

    • Optional config: Config

      An object with configuration options.

    Returns Database

  • Creates a new Database instance with its own connection pool.

    See also database.

    Example

    const db = new Database("http://127.0.0.1:8529", "my_database");
    db.useBasicAuth("admin", "hunter2");

    Parameters

    • url: string | string[]

      Base URL of the ArangoDB server or list of server URLs. Equivalent to the url option in Config.

    • Optional name: string

    Returns Database

Accessors

  • get name(): string
  • Name of the ArangoDB database this instance represents.

    Returns string

Methods

  • Updates the URL list by requesting a list of all coordinators in the cluster and adding any endpoints not initially specified in the Config.

    For long-running processes communicating with an ArangoDB cluster it is recommended to run this method periodically (e.g. once per hour) to make sure new coordinators are picked up correctly and can be used for fail-over or load balancing.

    Example

    const db = new Database();
    const interval = setInterval(
    () => db.acquireHostList(),
    5 * 60 * 1000 // every 5 minutes
    );

    // later
    clearInterval(interval);
    system.close();

    Parameters

    • overwrite: boolean = false

      If set to true, the existing host list will be replaced instead of extended.

    Returns Promise<void>

  • Returns an Analyzer instance representing the Analyzer with the given analyzerName.

    Example

    const db = new Database();
    const analyzer = db.analyzer("some-analyzer");
    const info = await analyzer.get();

    Parameters

    • analyzerName: string

    Returns Analyzer

  • Fetches all Analyzers visible in the database and returns an array of Analyzer instances for those Analyzers.

    See also listAnalyzers.

    Example

    const db = new Database();
    const analyzers = await db.analyzers();
    // analyzers is an array of Analyzer instances

    Returns Promise<Analyzer[]>

    const vertices = db.collection("vertices");
    const edges = db.collection("edges");
    const trx = await db.beginTransaction({
    read: ["vertices"],
    write: [edges] // collection instances can be passed directly
