What is the type of transaction prop?

When creating a transaction I get this prop

const transaction = client.transaction((tx) => {
  
})

const transaction = client.transaction((tx) => {
  
})

I am trying to define a function like this

async function createUser(client:Client | Transaction = db, data:Data){
client.insert(...)
}

async function createUser(client:Client | Transaction = db, data:Data){
client.insert(...)
}

This way I can reuse the same functions with and without a transaction, I am having trouble typing the Transaction type, the type in vscode is a long complex type and I was wondering if there is some exported type I could use

right now I am typing it like this

export type Transaction = PgTransaction<PostgresJsQueryResultHKT, typeof import('/Users/john/Desktop/projects/project/packages/db/src/schema/index'), ExtractTablesWithRelations<typeof import('/Users/john/Desktop/projects/project/packages/db/src/schema/index')>>;

export type Transaction = PgTransaction<PostgresJsQueryResultHKT, typeof import('/Users/john/Desktop/projects/project/packages/db/src/schema/index'), ExtractTablesWithRelations<typeof import('/Users/john/Desktop/projects/project/packages/db/src/schema/index')>>;

but I want to get rid of at least the imports, it's gonna mess up when building on cloud

export DbType= typeof<db> this should work. simple typescript

For postgres it is

import { type PostgresJsDatabase } from "drizzle-orm/postgres-js";

import { type PostgresJsDatabase } from "drizzle-orm/postgres-js";

If anyone else runs across this here's what worked for me. This is an easy way to get the actual transaction type. (Using typeof db may work but it isn't the same.) tx: Parameters<Parameters<typeof db.transaction>[0]>[0]
