Error: [unenv] fs.readFile is not implemented yet when getting presigned url with s3 packages.

I am trying to get a presigned put url for my R2 bucket, but getting the above error when getSignedUrl is executed.

    const R2_URL = `https://${ctx.env.ACCOUNT_ID}.r2.cloudflarestorage.com`
    const s3Client = new S3Client({
      region: "auto",
      endpoint: R2_URL,
      credentials: {
        accessKeyId: ctx.env.ACCESS_KEY_ID,
        secretAccessKey: ctx.env.ACCESS_KEY,
      },
    })
    const objectKey = `${app.slug}/${input.name}`
    const cmd = new PutObjectCommand({
      Bucket: ctx.env.BUCKET_NAME,
      Key: objectKey,
    })
    const signedUrl = await getSignedUrl(s3Client, cmd, { expiresIn: 3600 })

    const R2_URL = `https://${ctx.env.ACCOUNT_ID}.r2.cloudflarestorage.com`
    const s3Client = new S3Client({
      region: "auto",
      endpoint: R2_URL,
      credentials: {
        accessKeyId: ctx.env.ACCESS_KEY_ID,
        secretAccessKey: ctx.env.ACCESS_KEY,
      },
    })
    const objectKey = `${app.slug}/${input.name}`
    const cmd = new PutObjectCommand({
      Bucket: ctx.env.BUCKET_NAME,
      Key: objectKey,
    })
    const signedUrl = await getSignedUrl(s3Client, cmd, { expiresIn: 3600 })

database connection doesn't work in / behave strangely in global context.

this doesn't work

const db = new Kysely<DB>({
  dialect: new PostgresDialect({ pool: new Pool({ connectionString }) }),
});

app.get("/", async (c) => {
  const langs = await db.selectFrom("Language").selectAll().executeTakeFirst();
  return c.json(langs);
});

const db = new Kysely<DB>({
  dialect: new PostgresDialect({ pool: new Pool({ connectionString }) }),
});

app.get("/", async (c) => {
  const langs = await db.selectFrom("Language").selectAll().executeTakeFirst();
  return c.json(langs);
});

this however does work fine.

app.get("/", async (c) => {
  const db = new Kysely<DB>({
    dialect: new PostgresDialect({ pool: new Pool({ connectionString }) }),
  });
  const langs = await db.selectFrom("Language").selectAll().executeTakeFirst();
  return c.json(langs);
});

app.get("/", async (c) => {
  const db = new Kysely<DB>({
    dialect: new PostgresDialect({ pool: new Pool({ connectionString }) }),
  });
  const langs = await db.selectFrom("Language").selectAll().executeTakeFirst();
  return c.json(langs);
});

both work fine in lambdas. what's happening ?

my worker is throwing too many, error 1101.

I am migrating from Lambda, I was using this code

import pg from "pg"
import { Kysely, ParseJSONResultsPlugin, PostgresDialect } from "kysely"

import type { DB } from "../../db/src"

const { Pool } = pg

const globaldb = global as unknown as { db: Kysely<DB> }

export const db =
  globaldb.db ||
  new Kysely<DB>({
    dialect: new PostgresDialect({ pool: new Pool({ connectionString: process.env.DATABASE_URL }) }),
    plugins: [new ParseJSONResultsPlugin()],
  })

if (process.env.NODE_ENV !== "production") {
  globaldb.db = db
}

import pg from "pg"
import { Kysely, ParseJSONResultsPlugin, PostgresDialect } from "kysely"

import type { DB } from "../../db/src"

const { Pool } = pg

const globaldb = global as unknown as { db: Kysely<DB> }

export const db =
  globaldb.db ||
  new Kysely<DB>({
    dialect: new PostgresDialect({ pool: new Pool({ connectionString: process.env.DATABASE_URL }) }),
    plugins: [new ParseJSONResultsPlugin()],
  })

if (process.env.NODE_ENV !== "production") {
  globaldb.db = db
}

but in case of my worker, one request works & the other does not, not sure what's wrong here.

Replacing the dot notation in URLs with forward slash `/` ?

is there a way to replace the dot separation with a forward slash instead ?
so instead of /api/trpc/post.byId it would be /api/trpc/post/byId

Nested procedures are separated by dots, is there a way to change that to `/`s instead ?

currently it looks something like this /api/trpc/post.byId, is there a way to have it like /api/trpc/post/byId ?

Is there a way to split a trpc api across multiple lambdas ?

How do I go about splitting my TRPC api across multiple lambdas, such that each lambda would load the minimum code it needs to run, (ideally the frontend should not be affected )

somehow when move typed function out of the router files, frontend infer type to be any ?

this is inferred corrected since they are in the same file.

getX: t.procedure.query(() => {
 return getX()
}) 

function getX(): X{
  ...
}

getX: t.procedure.query(() => {
 return getX()
}) 

function getX(): X{
  ...
}

getX: t.procedure.query(() => {
 return getX()
}) 

export function getX(): X{ << moving this out of the file breaks the typing.
  ...
}

getX: t.procedure.query(() => {
 return getX()
}) 

export function getX(): X{ << moving this out of the file breaks the typing.
  ...
}
