kysely-postgres-js

kysely-postgres-js

Kysely dialect for PostgreSQL using the Postgres.js client library under the hood (version >= 3.4).

This dialect should not be confused with Kysely's built-in PostgreSQL dialect, which uses the pg client library instead.

Installation

npm i kysely-postgres-js

NPM <7

npm i kysely-postgres-js kysely postgres

Yarn

yarn add kysely-postgres-js kysely postgres

Deno

This package uses/extends some Kysely types and classes, which are imported using its NPM package name -- not a relative file path or CDN url. It also uses [Postgres.js] which is imported using its NPM package name -- not a relative file path or CDN url.

To fix that, add an import_map.json file.
