Abstracted routes but with context and types

I know there's some discussion of abstracted routes under https://hono.dev/docs/guides/best-practices. But there's no example which preserves the types from the context or middleware.

import hello from "./hello.ts"

type Env = {Variables: { db: typeof db }}

const factory = createFactory<Env>({
  initApp: (app) => {
    app.use(async (ctx, next) => {
      ctx.set("db", db)
      await next()
    })
  },
})

export const app = factory.createApp()

app.route("hello", hello)

import hello from "./hello.ts"

type Env = {Variables: { db: typeof db }}

const factory = createFactory<Env>({
  initApp: (app) => {
    app.use(async (ctx, next) => {
      ctx.set("db", db)
      await next()
    })
  },
})

export const app = factory.createApp()

app.route("hello", hello)

How should I construct hello.ts so that the subroutes all have access to db in the context?

drizzle-kit push connection cleanup

How do I run a cleanup script after drizzle-kit push, such as to kill database connections? Otherwise I noticed that drizzle-kit leaves connections open.

Maximum call stack for transactions

I've been trying to do a transaction over 100k rows (works at 10k) but I've been getting an error for stack size. How do I handle bigger transactions?

Postgres Schema (namespace)

Does anyone have a minimal example of a Drizzle postgres schema that uses the Postgres "Schema" (namespace) feature? On drizzle kit push I keep getting error: schema "meow" does not exist.

import { sql } from "drizzle-orm"
import {
  index,
  serial,
  timestamp,
  pgSchema,
  text,
} from "drizzle-orm/pg-core"

const schema = pgSchema("meow")

const time = (name="time") => timestamp(name, { withTimezone: true, mode: "date" }).default(sql`CURRENT_TIMESTAMP`).notNull()
const event = schema.enum("event_type", ["click", "buy", "poll"])

export const User = schema.table("user", {
  id:       text("id").primaryKey(),
  email:    text("email").unique().notNull(),
  hash:     text("hash").notNull(),
  username: text("username").unique().notNull(),
})

import { sql } from "drizzle-orm"
import {
  index,
  serial,
  timestamp,
  pgSchema,
  text,
} from "drizzle-orm/pg-core"

const schema = pgSchema("meow")

const time = (name="time") => timestamp(name, { withTimezone: true, mode: "date" }).default(sql`CURRENT_TIMESTAMP`).notNull()
const event = schema.enum("event_type", ["click", "buy", "poll"])

export const User = schema.table("user", {
  id:       text("id").primaryKey(),
  email:    text("email").unique().notNull(),
  hash:     text("hash").notNull(),
  username: text("username").unique().notNull(),
})

Raw SQL query (`.execute()` doesn't exist)

I'm trying to run a raw SQL query for sqlite3 with the Bun driver and I'm finding that .execute() doesn't exist. Anyone got any leads?

import Database from "bun:sqlite"
import { drizzle } from "drizzle-orm/bun-sqlite"

/** raw Bun database client */
export const sqlite = new Database("db.sqlite", { strict: true })

/** Drizzle database client */
export const db = drizzle(sqlite)

const email = "[email protected]"

const query = sql<{exists:boolean}>`select exists(${db.select({ n: sql`1` }).from(User).where(eq(User.email, email))}) as exists`

import Database from "bun:sqlite"
import { drizzle } from "drizzle-orm/bun-sqlite"

/** raw Bun database client */
export const sqlite = new Database("db.sqlite", { strict: true })

/** Drizzle database client */
export const db = drizzle(sqlite)

const email = "[email protected]"

const query = sql<{exists:boolean}>`select exists(${db.select({ n: sql`1` }).from(User).where(eq(User.email, email))}) as exists`

Postgres Schema (namespace) + Drizzle

How do I specify a Postgres schema (as in the psql namespace feature) for drizzle.config.ts? A connection string with database?schema=blah hasn't worked for me.

Drizzle + Postgres Schema

Has anyone figured out how to get Drizzle working with a Postgres schema (the Postgres namespacing feature)? I've tried databaseName?schema=schemaName in my database connection string to no avail.

TRPC vanilla queries (T3 stack)

Does anyone know how to access trpc vanilla queries (not hooks)?

async function handler() {
   const response = await api.example.hello.useQuery() // more like a fetch then a react hook.
   console.log(response)
}

async function handler() {
   const response = await api.example.hello.useQuery() // more like a fetch then a react hook.
   console.log(response)
}

TRPC Vanilla Client (T3 stack)

I'm using the T3 stack (Next + TRPC + etc) and I'm trying to figure out how to do vanilla queries that don't come with the baggage of a hook.

const hello = await api.example.hello.useQuery()

const hello = await api.example.hello.useQuery()

Prisma `delete` a row with composite keys

I’m trying to delete a single row in Prisma using composite keys x, y. Is it possible to write a query like prisma.table.delete({ where: { x, y }) or do you have to use deleteMany , which presumably doesn’t have a limit 1?

Enrich the response object for TRPC endpoint

Currently when I hit a trpc endpoint I get something like:

{
   result: {
      data: ...
   }
}

{
   result: {
      data: ...
   }
}

Is there any way to add more metadata, like:

{
   result: {
      data: ...
   }
   meta: {
      time: 10ms,
   }
}

{
   result: {
      data: ...
   }
   meta: {
      time: 10ms,
   }
}

TypeScript type for request object for route handlers

So far I've been writing my routes like:

export const router = t.router({
  helloWorld: t.procedure.query(async (req) => "Hello World"),
})

export const router = t.router({
  helloWorld: t.procedure.query(async (req) => "Hello World"),
})

What would be the type for req if I wanted to extract my handlers like so:

const handler = async (req:?) => "Hello World"

export const router = t.router({
  helloWorld: t.procedure.query(hander)
})

const handler = async (req:?) => "Hello World"

export const router = t.router({
  helloWorld: t.procedure.query(hander)
})
