surrealdb-cloudflare

SurrealDB on the edge!

Cloudflare workers

This module has been build specifically to be compatible with cloudflare workers. Tested with wrangler2, though should probably work fine with wrangler1 aswell.

Basic interpetation

It's just a basic interpetation of the SurrealDB HTTP/REST API, You can check them here: https://surrealdb.com/docs/integration/http

Get started

You can check out the demo.ts file or check the examples down below:

Connection variables from environment

import Surreal from 'surrealdb-cloudflare';

// Type safety, typescript example :D
type Env = {
    HOST: string;
    USER: string;
    PASS: string;
    NAMESPACE: string;
    DATABASE: string;
}

// We can update the connection variables later on, as we don't have them available here just yet...
const db = new Surreal();

export default {
	async fetch(
		request: Request,
        env: Env
	): Promise<Response> {
        // If database not yet connected, let's update the connection details.
        if (!db.connected()) db.connect({
            host: env.HOST ?? '',
            username: env.USER ?? '',
            password: env.PASS ?? '',
            namespace: env.NAMESPACE ?? '',
            database: env.DATABASE ?? ''
        });

        // Example query: Retrieves all records from table 'table'.
        let res = await db.getRecords('table');
		console.log(res[0].result);

		return new Response("Hello World!");
	},
};

Connection variables defined in code

import Surreal from 'surrealdb-cloudflare';

// We can update the connection variables later on, as we don't have them available here just yet...
const db = new Surreal({
    host: 'http://surreal.domain.com',
    username: 'root',
    password: 'password',
    namespace: 'awesome',
    database: 'example'
});

export default {
	async fetch(
		request: Request
	): Promise<Response> {
        // Example query: Retrieves all records from table 'table'.
        let res = await db.getRecords('table');
		console.log(res[0].result);

		return new Response("Hello World!");
	},
};

Strong type result

const res = await db.getRecords<{
    id: string;
    username: string;
    status: "verified" | "unverified";
}>('user');

res.forEach(record => {
    // Everything in "result" is now strong typed with the defined type.
    const { result } = record;
    console.log(`${result.id} - User ${result.username} is ${result.status}`);
});
