JavaScript: Easy Prisma adapter for completeTx

[brandur]

This one doesn't something similar to a piece of #1516 that we'd added.

Currently, you can use Prisma on insertions relatively easily, but
workers still run off PgDriver, making it somewhat unergonomic to
invoke transactional completion (completeTx) from within a worker.
Here, we add an adapter that makes it very easy.

prismaTransactionAdapter is configured on PgDriver, and from there
you've got easy access to a completeTx in any worker that'll take a
Prisma $transaction object:

import { PrismaPg } from "@prisma/adapter-pg";
import { PgDriver } from "@riverqueue/driver-pg";
import { prismaTransactionAdapter } from "@riverqueue/driver-prisma";
import { Pool } from "pg";
import { Client, defineJob, Workers } from "riverqueue";
import { PrismaClient, type Prisma } from "./generated/prisma/client.js";

const connection = { connectionString: process.env.DATABASE_URL };
const prisma = new PrismaClient({ adapter: new PrismaPg(connection) });

const syncAccount = defineJob<{ accountId: string }>()({
  kind: "sync_account",
});

const workers = new Workers<Prisma.TransactionClient>().add(
  syncAccount,
  async ({ completeTx, job }) => {
    await prisma.$transaction(async (tx) => {
      await tx.account.update({
        where: { id: job.args.accountId },
        data: { synced: true },
      });
      await completeTx(tx);
    });
  }
);

const client = new Client(
  new PgDriver(new Pool(connection), {
    transactionAdapters: [prismaTransactionAdapter],
  }),
  { queues: { default: { maxWorkers: 10 } }, workers }
);

await client.start();
