SvelteKit DB

Cross-platform database solution for SvelteKit.

pnpm i -D sveltekit-db

Usage

sveltekit-db uses kysely under the hood.

You can define your database schema like:

// src/lib/db/schema.ts
export interface User {
    id: number;
    name: string;
    email: string;
}

export interface Document {
    id: number;
    owner: number;
    title: string;
    content: string;
}

export interface Database {
    User: User;
    Document: Document;
}

// src/lib/db/index.ts
import { DB } from "sveltekit-db";
import type { Database } from "./schema";

export const db = DB<Database>();

Then you can use it like:

import { db } from "$lib/db";
import type { PageServerLoad } from "./$types";

export const load: PageServerLoad = async () => {
    const documents = await db
        .selectFrom("Document")
        .where("Document.owner", "=", 1)
        .select(["Document.id", "Document.title", "Document.content"])
        .limit(10)
        .execute();

    return { documents };
};
