example of kysely running on deno deploy?

Tthorwebdev1/17/2023
Deno Deploy awesomely can connect to postgres directly from the edge https://deno.com/blog/deploy-postgres-at-the-edge so I was hoping to use https://github.com/koskimas/kysely#deno Was trying to make it work like this:
import { Pool } from 'https://deno.land/x/pg@v0.6.1/mod.ts'
import { serve } from 'https://deno.land/std@0.114.0/http/server.ts'
import {
Kysely,
PostgresDialect,
Generated,
ColumnType,
Selectable,
Insertable,
Updateable,
} from 'https://esm.sh/kysely@0.23.4'

console.log(`Function "kysely-postgres" up and running!`)

interface AnimalTable {
id: Generated<number>
animal: string
created_at: Date
}

// Keys of this interface are table names.
interface Database {
animal: AnimalTable
}

// You'd create one of these when you start your app.
const db = new Kysely<Database>({
// Use MysqlDialect for MySQL and SqliteDialect for SQLite.
dialect: new PostgresDialect({
// @ts-ignore
pool: new Pool({
user: 'postgres',
hostname: 'db.bljghubhkofddfrezkhn.supabase.co',
database: 'postgres',
password: Deno.env.get('DB_PASSWORD')!,
port: 5432,
}),
}),
})
import { Pool } from 'https://deno.land/x/pg@v0.6.1/mod.ts'
import { serve } from 'https://deno.land/std@0.114.0/http/server.ts'
import {
Kysely,
PostgresDialect,
Generated,
ColumnType,
Selectable,
Insertable,
Updateable,
} from 'https://esm.sh/kysely@0.23.4'

console.log(`Function "kysely-postgres" up and running!`)

interface AnimalTable {
id: Generated<number>
animal: string
created_at: Date
}

// Keys of this interface are table names.
interface Database {
animal: AnimalTable
}

// You'd create one of these when you start your app.
const db = new Kysely<Database>({
// Use MysqlDialect for MySQL and SqliteDialect for SQLite.
dialect: new PostgresDialect({
// @ts-ignore
pool: new Pool({
user: 'postgres',
hostname: 'db.bljghubhkofddfrezkhn.supabase.co',
database: 'postgres',
password: Deno.env.get('DB_PASSWORD')!,
port: 5432,
}),
}),
})
But am getting Unknown Authentication type, code: 10, message: SCRA

Connecting to Postgres from the edge
Many serverless at edge products can not connect to Postgres because they don't support TCP. Deno Deploy can.

Why such an old version of deno std ? you imported 0.114.0 latest is 0.173.0

Probably because I copy and paste from examples that are not being updated 😬 Thanks @ndh3193 updating deno std import { serve } from "https://deno.land/std@0.175.0/http/server.ts" makes the function runnable, but unfortunately upon invocation I get

Not sure if that's a Deno deploy quirk
