Installation

Requirements

Node.js 20 or later
npm (the package ships ESM only — no CJS build)
TypeScript 5+ recommended

Install the package

npm install @loewen-digital/fullstack

That’s the only required dependency. Driver-specific peer dependencies (Redis client, AWS SDK, etc.) are optional and only needed when you use those drivers.

Optional peer dependencies

Install only what you need:

# Redis (for session, cache, or queue drivers)
npm install ioredis

# S3 / R2 storage
npm install @aws-sdk/client-s3

# Resend email
npm install resend

# Postmark email
npm install postmark

# Meilisearch
npm install meilisearch

# Typesense
npm install typesense

TypeScript setup

The package requires "moduleResolution": "bundler" or "node16" / "nodenext" in your tsconfig.json because all internal imports use .js extensions (ESM standard).

{
  "compilerOptions": {
    "target": "ESNext",
    "module": "ESNext",
    "moduleResolution": "bundler",
    "strict": true
  }
}

Verify the installation

import { validate } from '@loewen-digital/fullstack/validation'

const result = validate({ name: 'Alice' }, { name: ['required', 'string'] })
console.log(result.passes) // true

If this compiles and runs without errors, you’re good to go. Head to the Quick Start to build something real.
