Client-side Support

[rob-gordon]

Is this package intended to work in the browser? I'm currently trying to initialize an IndexedDB-backed PGlite database on the client-side, but create-migrator seems to rely on packages which expect to be run in node.

My code:

import { createMigrator, KyselyPGlite } from "kysely-pglite";
import { Dialect, Kysely } from "kysely";
import { openDB } from "idb";
import type { DB } from "./schema";

const DB_NAME = "my-db";
const DB_VERSION = 1;

async function initializeDatabase() {
  // Open or create the IndexedDB database
  await openDB(DB_NAME, DB_VERSION);

  // Create a KyselyPGlite instance backed by IndexedDB
  const dialect = new KyselyPGlite(`idb://${DB_NAME}`);

  // Create the Kysely instance
  const db = new Kysely<DB>({
    dialect: dialect as unknown as Dialect,
    log(event) {
      console.log(event.query.sql);
      console.log(event.query.parameters);
    },
  });

  // Create the migrator
  const migrator = createMigrator(db, "src/db/migrations");

  // Run migrations
  console.log("Migrating to latest");
  const { error, results } = await migrator.migrateToLatest();

  if (error) {
    console.error("Migration failed:", error);
  } else if (results) {
    console.log("Migration results:", results);
  }

  return db;
}

// Export a promise that resolves to the db instance
export const dbPromise = initializeDatabase();

Next is unable to build this because the migrator has packages in it's dependency tree which expect to have fs present.

Module not found: Can't resolve 'fs'
Did you mean './fs'?
Requests that should resolve in the current directory need to start with './'.
Requests that start with a name are treated as module requests and resolve within module directories (node_modules).
If changing the source code is not an option there is also a resolve options called 'preferRelative' which tries to resolve these kind of requests in the current directory too.
