Kysely adapter for Cloudflare D1.
npm i kysely-d1This project was largely adapted from kysely-planetscale.
Pass your D1 binding into the dialect in order to configure the Kysely client. Follow these docs for instructions on how to do so.
import { Kysely } from 'kysely';
import { D1Dialect } from 'kysely-d1';
export interface Env {
DB: D1Database;
}
interface KvTable {
key: string;
value: string;
}
interface Database {
kv: KvTable;
}
export default {
async fetch(request: Request, env: Env): Promise<Response> {
const { searchParams } = new URL(request.url);
const key = searchParams.get('key');
if (!key) {
return new Response('No key defined.', { status: 400 });
}
// Create Kysely instance with kysely-d1
const db = new Kysely<Database>({ dialect: new D1Dialect({ database: env.DB }) });
// Read row from D1 table
const result = await db.selectFrom('kv').selectAll().where('key', '=', key).executeTakeFirst();
if (!result) {
return new Response('No value found', { status: 404 });
}
return new Response(result.value);
},
};There is a working example also included, which implements a K/V style store using D1.
