surrealdb.js

surrealdb.js

The official SurrealDB library for JavaScript.

Quickstart-Guide

Install

Deno

Import it with

import Surreal from "https://deno.land/x/surrealdb/mod.ts";

Note you should set a version in the url! For example https://deno.land/x/surrealdb@0.5.0/mod.ts

NodeJS, or browser with a bundler

For NodeJS or a browser with bundler (for example: rollup, vite, or webpack) you can just: install the npm package:

npm i surrealdb.js
# or with yarn
yarn add surrealdb.js
# or with pnpm
pnpm i surrealdb.js

then, just import it with:

import Surreal from "surrealdb.js";

or when you use CommonJS

const { default: Surreal } = require("surrealdb.js");

CDN for Browser

For fast prototyping we provide a browser-ready bundle. You can import it with

import Surreal from "https://unpkg.com/surrealdb.js";
// or
import Surreal from "https://cdn.jsdelivr.net/npm/surrealdb.js";

NOTE: this bundle is not optimized for production! So don't use it in production!

Getting started

Here you have a simple example!

This example uses top level await wich is available in deno, node >= 14.8, modern browsers (https://caniuse.com/mdn-javascript_operators_await_top_level).

const db = new Surreal();

try {
	// Connect to the database
	await db.connect("http://127.0.0.1:8000/rpc");

	// Signin as a namespace, database, or root user
	await db.signin({
		user: "root",
		pass: "root",
	});

	// Select a specific namespace / database
	await db.use({ ns: "test", db: "test" });

	// Create a new person with a random id
	let created = await db.create("person", {
		title: "Founder & CEO",
		name: {
			first: "Tobie",
			last: "Morgan Hitchcock",
		},
		marketing: true,
		identifier: Math.random().toString(36).substr(2, 10),
	});

	// Update a person record with a specific id
	let updated = await db.merge("person:jaime", {
		marketing: true,
	});

	// Select all people records
	let people = await db.select("person");

	// Perform a custom advanced query
	let groups = await db.query(
		"SELECT marketing, count() FROM type::table($tb) GROUP BY marketing",
		{
			tb: "person",
		},
	);
} catch (e) {
	console.error("ERROR", e);
}

Contribution notes

Local setup

This is a Deno project, not NodeJS. For example, this means import paths include the .ts file extension. However, to also support other JavaScript environments, a build has been added to create a npm package that works for NodeJS, Bun, browsers with bundlers.

Supported environments

• Deno
• NodeJS
• Bun
• Web Browsers

Requirements

• Deno
• npm
• NodeJS
• Docker (for e2e tests)
• Bun (for e2e tests)

Build for all supported environments

For Deno, no build is needed. For all other environments run

deno task build.

Formatting

deno fmt

Linting

deno lint

PRs

Before you commit, please format and lint your code accordingly to check for errors.

Local setup

For local development the Deno extension for VSCode is helpful (hint: local Deno installation required).

Directory structure

• ./mod.ts is the deno entypoint. This is just a reexport of ./src/index.ts
• ./deno.json include settings for linting + formating.
• ./compile.ts include the build script for the npm package.
• ./src includes all source code. ./src/index.ts is the main entrypoint.
• ./npm is build by ./compile.ts and includes the generated npm package.
• ./test includes all test files. To add a test modify ./test/e2e/shared.js.
