Connect to Supabase with Prisma on the Edge (e.g. Vercel Edge functions). Test locally by running the Supabase connection pooler
import { neonConfig, Pool } from '@neondatabase/serverless'
import { PrismaNeon } from '@prisma/adapter-neon'
import { PrismaClient } from '@prisma/client'
import { WebSocket } from 'ws'
// Example Supabase pooled connection string (must use Supavisor)
const connectionString =
'postgres://[username].[id]:[password]@aws-0-us-east-1.pooler.supabase.com:5432/[db]'

Pure ESM package

Pure ESM package

The package that linked you here is now pure ESM. It cannot be require()'d from CommonJS.

This means you have the following choices:

  1. Use ESM yourself. (preferred)
    Use import foo from 'foo' instead of const foo = require('foo') to import the package. You also need to put "type": "module" in your package.json and more. Follow the below guide.
  2. If the package is used in an async context, you could use await import(…) from CommonJS instead of require(…).
  3. Stay on the existing version of the package until you can move to ESM.
