    The official Node.js client library for EdgeDB

    Build status NPM version Stars

    Quickstart   •   Website   •   Docs   •   Discord   •   Twitter

    This is the official EdgeDB client library for JavaScript and TypeScript.

    If you're just getting started with EdgeDB, we recommend going through the EdgeDB Quickstart first. This walks you through the process of installing EdgeDB, creating a simple schema, and writing some simple queries.

    Migrating to EdgeDB 2.0

    We recently released v0.21.0 of the edgedb module on NPM and, which supports the latest EdgeDB 2.0 features and protocol. It is backwards-compatible with v1 instances as well, so we recommend all users upgrade.

    npm install edgedb@latest

    Breaking changes

    • All uuid properties are now decoded to include hyphens. Previously hyphens were elided for performance reasons; this issue has since been resolved.

      client.querySingle(`select uuid_generate_v1mc();`);
      // "ce13b17a-7fcd-42b3-b5e3-eb28d1b953f6"
    • All json properties and parameters are now parsed/stringified internally by the client. Previously:

      const result = await client.querySingle(
        `select to_json('{"hello": "world"}');`
      result; // '{"hello": "world"}'
      typeof result; // string


      const result = await client.querySingle(
        `select to_json('{"hello": "world"}');`
      result; // {hello: "world"}
      typeof result; // object
      result.hello; // "world"

    New features

    • Added the .withGlobals method to the Client for setting global variables.

      import {createClient} from "edgedb";
      const client = createClient().withGlobals({
        current_user: getUserIdFromCookie(),
      client.query(`select User { email } filter .id = global current_user;`);
    • Support for globals in the query builder.

      const query =, user => ({
        email: true,
        filter: e.op(, "=",,
    • Support for the group statement., movie => ({
        title: true,
        actors: {name: true},
        num_actors: e.count(movie.characters),
        by: {release_year: movie.release_year},
      /* [
          key: {release_year: 2008},
          grouping: ["release_year"],
          elements: [{
            title: "Iron Man",
            actors: [...],
            num_actors: 5
          }, {
            title: "The Incredible Hulk",
            actors: [...],
            num_actors: 3
        // ...
      ] */
    • Support for range types and DateDuration values.


    • Node.js 12+
    • For TypeScript users:
      • TypeScript 4.4+ is required
      • yarn add @types/node --dev


    npm install edgedb      # npm users
    yarn add edgedb         # yarn users

    Basic usage

    The examples below demonstrate only the most fundamental use cases for this library. Go to the complete documentation site. >

    Create a client

    A client is an instance of the Client class, which maintains a pool of connections to your database and provides methods for executing queries.

    For TypeScript (and Node.js+ESM)

    import * as edgedb from "edgedb";
    const client = edgedb.createClient();

    For Node.js (CommonJS)

    const edgedb = require("edgedb");
    const client = edgedb.createClient();

    Configuring the connection

    The call to edgedb.createClient() doesn't require arguments, as the library can determine how to connect to your database using the following mechanisms.

    1. For local development: initialize a project with the edgedb project init command. As long as the file is within a project directory, createClient will be able to auto-discover the connection information of the project's associated instance. For more information on projects, follow the Using projects guide.

    2. In production: configure the connection using environment variables. (This can also be used during local development if you prefer.) The easiest way is to set the EDGEDB_DSN variable; a DSN (also known as a "connection string") is a string of the form edgedb://USERNAME:PASSWORD@HOSTNAME:PORT/DATABASE.

    For advanced cases, see the DSN specification and Reference > Connection Parameters.

    Run a query

    The remainder of the documentation assumes you are using ES module (import) syntax.

    import * as edgedb from "edgedb";
    const client = edgedb.createClient();
    await client.query("select 2 + 2"); // => [4]

    Note that the result is an array. The .query() method always returns an array, regardless of the result cardinality of your query. If your query returns zero or one elements, use the .querySingle() instead.

    // empty set, zero elements
    await client.querySingle("select <str>{}"); // => null
    // one element
    await client.querySingle("select 2 + 2"); // => 4
    // one element
    await client.querySingle(
      `select Movie { title }
      filter .id = <uuid>'2eb3bc76-a014-45dc-af66-2e6e8cc23e7e';`
    ); // => { title: "Dune" }

    Query builder

    Instead of writing queries as strings, you can use this package to generate a query builder. The query builder lets you write queries in a code-first way and automatically infers the return type of your queries.

    To generate the query builder, install the edgedb package, initialize a project (if you haven't already), then run the following command:

    $ npx edgeql-js

    This will generate an EdgeQL query builder into the ./dbschema/edgeql-js directory, as defined relative to your project root.

    For details on generating the query builder, refer to the complete documentation. Below is a simple select query as an example.

    import {createClient} from "edgedb";
    import e from "./dbschema/edgeql-js";
    const client = createClient();
    const query =, movie => ({
      id: true,
      title: true,
      actors: {name: true},
      num_actors: e.count(movie.actors),
      filter: e.op(movie.title, "=", "Dune"),
    const result = await;
    result.actors[0].name; // => Timothee Chalamet

    For details on using the query builder, refer to the full query builder docs.
