Prisma Monorepo Support

[vinnymac]

I raised this on Discord, where I was asked to create this issue, so I am x-posting the feature request to GitHub.

Background

When using a NodeJS monorepo such as Turborepo, Lerna, Yarn, NX, etc, it is currently not possible to use DBOS with Prisma. You receive an error that the @prisma/client node module cannot be found.

This is due to the following lines of code:

dbos-transact-ts/src/dbos-executor.ts

Lines 250 to 252 in 8f0652b

	// TODO: make Prisma work with debugger proxy.
	// eslint-disable-next-line @typescript-eslint/no-unsafe-assignment, @typescript-eslint/no-require-imports
	const { PrismaClient } = require(path.join(process.cwd(), "node_modules", "@prisma", "client")); // Find the prisma client in the node_modules of the current project

In various monorepos it is considered best practice to keep the Prisma schema and client in a separate workspace package, and the @prisma/client module itself is often located in the root projects node modules folder.

Expectation

DBOS on Prisma works as normal in monorepos without throwing an error.

What have I tried?

I went ahead and applied a small patch to the aforementioned lines in a Turborepo, and confirmed that it works fine if you let it know where the root of the monorepo is located, as then it is able to locate the @prisma/client correctly. This works for my needs, but I imagine an official solution would be preferred by the community.

If I run into any other issues with monorepos I will let DBOS know, as I am integrating with DBOS for the first time in a Typescript based Turborepo project.
