npm: @powersync/kysely-driver

This package enables using Kysely with PowerSync React Native and web SDKs.

It gives JavaScript developers the flexibility to write queries in either JavaScript/TypeScript or SQL, and provides type-safe imperative APIs.

​
Setup

Set up the PowerSync Database and wrap it with Kysely.

​
JavaScript Setup

import { wrapPowerSyncWithKysely } from '@powersync/kysely-driver';
import { PowerSyncDatabase } from '@powersync/web';

// Define schema as in: https://docs.powersync.com/usage/installation/client-side-setup/define-your-schema
import { appSchema } from './schema';

export const powerSyncDb = new PowerSyncDatabase({
  database: {
    dbFilename: 'test.sqlite'
  },
  schema: appSchema
});

export const db = wrapPowerSyncWithKysely(powerSyncDb);

​
TypeScript Setup

import { wrapPowerSyncWithKysely } from '@powersync/kysely-driver';
import { PowerSyncDatabase } from "@powersync/web";

// Define schema as in: https://docs.powersync.com/usage/installation/client-side-setup/define-your-schema
import { appSchema, Database } from "./schema";

export const powerSyncDb = new PowerSyncDatabase({
  database: {
    dbFilename: "test.sqlite"
  },
  schema: appSchema,
});

// `db` now automatically contains types for defined tables
export const db = wrapPowerSyncWithKysely<Database>(powerSyncDb)
