@keyv/postgres

PostgreSQL storage adapter for Keyv

PostgreSQL storage adapter for Keyv.

Requires Postgres 9.5 or newer for ON CONFLICT support to allow performant upserts. Why?

Install

npm install --save keyv @keyv/postgres

Usage

import Keyv from 'keyv';
import KeyvPostgres from '@keyv/postgres';

const keyv = new Keyv(new KeyvPostgres('postgresql://user:pass@localhost:5432/dbname'));
keyv.on('error', handleConnectionError);

You can specify the table option.

e.g:

const keyv = new Keyv(new KeyvPostgres('postgresql://user:pass@localhost:5432/dbname'), { table: 'cache' });

You can specify the schema option (default is public).

e.g:

const keyv = new Keyv(new KeyvPostgres('postgresql://user:pass@localhost:5432/dbname'), { schema: 'keyv' });

Testing

When testing you can use our docker compose postgresql instance by having docker installed and running. This will start a postgres server, run the tests, and stop the server:

At the root of the Keyv mono repo:

yarn test:services:start

To just test the postgres adapter go to the postgres directory (packages/postgres) and run:

yarn test
