Connect to Postgres local vs Vercel Postgres with Kysely
I switched a codebase from local Postgres database to Vercel Postgres, which comes with its own optimized package.
I used this to set up Kysely:
import {
Kysely,
PostgresDialect,
} from 'kysely'
import pg from 'pg'
const POSTGRES_URL = //...from env
const dialect = new PostgresDialect({
pool: new pg.Pool({
connectionString:
POSTGRES_URL
max: 10,
}),
})
export const db = new Kysely({
dialect
})
With Vercel Postgres, I used:
import { createKysely } from '@vercel/postgres-kysely'
const POSTGRES_URL = //...from env
export const db = createKysely({
connectionString: POSTGRES_URL
})
The db
now already know how to look up the environment variable POSTGRES_URL
