pantheon-secrets

A lightweight TypeScript utility package for Node.js applications to retrieve secrets from Pantheon-style environment variables. It simplifies the process of fetching environment-specific and production secrets with full type safety.

Installation

You can install this package via npm:

npm install pantheon-secrets

Features

• 🔐 Secure secret management - Environment-based secret resolution
• 📦 Dual module support - Works with both ESM (import) and CommonJS (require)
• 🎯 TypeScript native - Full type safety and IntelliSense support
• 🚀 Zero dependencies - Lightweight with no external dependencies
• ✅ Well tested - Comprehensive test suite included

Usage

The package exposes a single function, pantheonGetSecret, which takes the name of a secret as a string and returns the corresponding value or null if not found.

ESM (Modern JavaScript/TypeScript)

import { pantheonGetSecret } from 'pantheon-secrets';

const mySecret = pantheonGetSecret('HELLO');
console.log(`The value of HELLO is: ${mySecret}`);

const anotherSecret = pantheonGetSecret('nonexistent');
console.log(`The value of nonexistent is: ${anotherSecret}`);
// The value of nonexistent is: null

CommonJS (Traditional Node.js)

const { pantheonGetSecret } = require('pantheon-secrets');

const mySecret = pantheonGetSecret('HELLO');
console.log(`The value of HELLO is: ${mySecret}`);

How It Works

The function automatically determines which secret to use based on your application's environment variables. It first checks for a live production secret, then looks for a value specific to your current environment, and finally falls back to a default value if no other options are found. If the secret is not defined, it returns null.
