Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@thynclabs/vault-whisper

@thynclabs/vault-whisper is a powerful and intuitive npm package designed to securely read secrets from Azure Key Vault and automatically set them as environment variables in your application. By transforming secret names into a consistent, snake_case uppercase format, @thynclabs/vault-whisper ensures easy and standardized access to sensitive information within your development and deployment environments.

Installation

To install, use npm or yarn:

npm install @thynclabs/vault-whisper
# or
yarn add @thynclabs/vault-whisper

Usage

Reading Secrets from Azure Key Vault

const { whisperSecrets } = require('@thynclabs/vault-whisper');

// Replace with your Azure Key Vault name and secret names
const keyVaultName = 'your-keyvault-name';
const secrets = ['secret-name-1', 'secret-name-2'];

whisperSecrets(keyVaultName, secrets)
    .then(() => {
        console.log('Secrets fetched and environment variables set successfully.');
    })
    .catch((err) => {
        console.error('Failed to fetch secrets:', err);
    });

Adding Secrets to Azure Key Vault

import { addSecret } from '@thynclabs/vault-whisper';

const vaultName = 'your-keyvault-name';
const secretName = 'new-secret-name';
const secretValue = 'your-secret-value';

addSecret(vaultName, secretName, secretValue)
  .then(() => {
    console.log(`Secret ${secretName} added to ${vaultName}`);
  })
  .catch(err => {
    console.error('Error adding secret:', err);
  });

NOTE:

The name of each environment variable will be converted to a snake_case uppercase format to ensure consistency and readability. This transformation involves replacing any hyphens (-) with underscores (_) and converting all letters to uppercase.

For instance, if the original secret name is secret-name-1, the corresponding environment variable that will be set is SECRET_NAME_1.

This convention helps maintain a standard naming format across environment variables, making them easily identifiable and manageable within your codebase.

Example Transformation:
  • Original Secret Name: secret-name-1
  • Transformed Environment Variable Name: SECRET_NAME_1
Steps Involved in the Transformation:
  1. Replace Hyphens with Underscores: Any hyphens (-) in the secret name are replaced with underscores (_).
  2. Convert to Uppercase: The entire string is then converted to uppercase letters.

By adhering to this transformation rule, you can ensure that all environment variables derived from secret names follow a consistent and clear naming pattern, facilitating better organization and access within your development and deployment environments.

Environment Variables

Ensure your environment has the following variables set:

  • AZURE_CLIENT_ID: Client ID of your Azure AD application (service principal).
  • AZURE_CLIENT_SECRET: Client secret associated with your Azure AD application.
  • AZURE_TENANT_ID: Azure AD tenant ID, required in some environments.

Configuration

Make sure your Azure AD application (service principal) has appropriate permissions to read secrets from the Azure Key Vault.
