Do

npm install @useverk/drizzle-pgvector

or

yarn add @useverk/drizzle-pgvector

or

pnpm add @useverk/drizzle-pgvector

And then in your code:

import { customVector } from '@useverk/drizzle-pgvector'
export const myTable = pgTable(
  'mytable',
  {
    ...
    embedding: customVector('embedding', { dimensions: 1536 }),
    ...
  })

Known issues

• [ ] running drizzle-kit generate will generate the following sql migration file:

  CREATE TABLE IF NOT EXISTS "myTable" (
  "id" serial PRIMARY KEY NOT NULL,
  "vector" "vector(1536)"
  );

  which is not valid postgresql syntax. Simply remove the quotes around the type name to fix it. The correct syntax is:

  CREATE TABLE IF NOT EXISTS "myTable" (
  "id" serial PRIMARY KEY NOT NULL,
  "vector" vector(1536)
  );

  Will fix this once drizzle-kit is open-source.
