Kolaybase + SvelteKit: Backend for Svelte Apps

SvelteKit covers routing and rendering; Kolaybase covers the backend. Use kolaybase-js in load functions and server endpoints to fetch and mutate data.

Install

npm install kolaybase-js

Create the client

// src/lib/kolaybase.ts
import { createClient } from "kolaybase-js";
import { PUBLIC_KOLAYBASE_PROJECT_ID, PUBLIC_KOLAYBASE_ANON_KEY } from "$env/static/public";

export const kb = createClient({
  projectId: PUBLIC_KOLAYBASE_PROJECT_ID,
  apiKey: PUBLIC_KOLAYBASE_ANON_KEY,
});

Use PUBLIC_ env variables with the anon key for client/load code. Keep service keys in private env variables for server-only logic.

Load data for a route

// src/routes/posts/+page.ts
import { kb } from "$lib/kolaybase";

export async function load() {
  const { data } = await kb.from("posts").select("id, title");
  return { posts: data ?? [] };
}

Works in load functions

Fetch data during SSR or on the client with the same SDK call.

No backend boilerplate

Skip writing endpoints for basic data access — query the database directly.

Auth and storage included

kb.auth and kb.storage cover sign-in and file uploads out of the box.

Frequently asked questions

Can I use Kolaybase in SvelteKit server endpoints?
Yes. Create a server-side client with a service key in +server.ts or +page.server.ts for trusted operations, and a public client for the browser.
Does row-level security still apply?
Yes. With the anon key, every query is constrained by your PostgreSQL row-level security policies.
