multidatastore-postgres

library3.0.1jsnpmunverified

PostgreSQL driver for multidatastore, a library enabling multiple data stores (e.g., databases) to be accessed through a unified interface. Version 3.0.1 is the latest release. This package provides the PostgreSQL implementation, supporting standard SQL operations within the multidatastore framework. Release cadence is ad-hoc, with no recent updates. It is a thin wrapper over connect-pg-simple and pg-pool, primarily used in Node.js environments with PostgreSQL.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

PostgresStore

✓ import { PostgresStore } from 'multidatastore-postgres'

✗ const PostgresStore = require('multidatastore-postgres')

ESM-only since v3; use dynamic import or transpilation for CJS

default

✓ import multidatastorePostgres from 'multidatastore-postgres'

✗ const multidatastorePostgres = require('multidatastore-postgres').default

Default export available; named exports also exist

PoolConfig

✓ import type { PoolConfig } from 'multidatastore-postgres'

✗ import { PoolConfig } from 'multidatastore-postgres'

PoolConfig is a TypeScript type; use type import to avoid runtime errors

Demonstrates instantiating a PostgresStore with a pg pool, setting and getting a key-value pair.

import { PostgresStore } from 'multidatastore-postgres'; import { createPool } from 'pg'; const pool = createPool({ host: process.env.PGHOST ?? 'localhost', port: parseInt(process.env.PGPORT ?? '5432'), database: process.env.PGDATABASE ?? 'mydb', user: process.env.PGUSER ?? 'user', password: process.env.PGPASSWORD ?? '', }); const store = new PostgresStore(pool); async function main() { await store.set('key', 'value'); const value = await store.get('key'); console.log(value); } main().catch(console.error);

Debug

Known issues

breakingVersion 3.x drops support for CommonJS; only ES modules are supported. Require() will throw Module not found.

fix

Use import syntax or upgrade to ESM-compatible environment.

affects: >=3.0.0

deprecatedConstructor signature changed: previous versions accepted connection string, now requires pg pool object.

fix

Create a pg.Pool instance and pass it to the constructor.

affects: >=3.0.0

breakingRemoved synchronous operations in v3; all methods return Promises.

fix

Use async/await or .then() for all store operations.

affects: >=3.0.0

Errors

Common errors & fixes

TypeError: store.set is not a function

Using old constructor signature with connection string instead of pg pool

fix

Create a pg.Pool and pass it: new PostgresStore(pool)

Cannot find module 'multidatastore-postgres'

Package not installed or using require() in ESM-only version

fix

Run npm install multidatastore-postgres and use import (ESM) syntax.

PoolConfig is not a constructor

Importing PoolConfig as a value instead of a type

fix

Use import type { PoolConfig } from 'multidatastore-postgres'.
