PostgreSQL Proxy Client (LibPQ Implementation)

This package provides a PGClient implementation directly connecting to PostgreSQL servers, and not requiring a PGProxy Server to run.

This is useful (mostly? only?) when running tests with a PostgreSQL instance running on a developer's machine, or in CI environments.

Usage with PGClient

Simply register the client by importing it, and ensure that the PGURL environment variable is set to the psql url of the PostgreSQL server (or specify the URL in the constructor):

import '@juit/pgproxy-client-psql'
import { PGClient } from '@juit/pgproxy-client'

const client = new PGClient('psql://username:password@locahost:5432/my-database')

Direct usage

The PSQL client can be used directly by simply importing the PSQLClient class:

import { PSQLClient } from '@juit/pgproxy-client-psql'

const client = new PSQLClient('psql://username:password@locahost:5432/my-database')

Environment Variables

The PSQLClient implementation does not require a connection URL, and all connection parameters can be specified via libpq environment variables.

The special (empty) URL psql:/// can be used with PGClient in order to trigger this behaviour or PSQLClient instances can be constructed without an URL parameter.

For a description of the environment variables supported by libpq simply look at the official documentation.
