AWS Config Executor

Loads and caches configuration and secrets from AWS services.

Description

• Resolve configuration from multiple source:
  • AWS SSM parameter store.
  • AWS Secrets Manager.
  • Local memory.
• Structured logging with Pino via mlabs-logger.
• Cache parameter values with cache-manager.
• Parameter key aliases (see usage below).

Basic Usage

Get configuration from AWS SSM Parameter Store and AWS Secrets Manager.

import { ssmString, secretsManagerString, getConfig } from '@pureskillgg/ace'

const parameters = {
  bucketArn: ssmString('/app/bucket_arn'),
  apiKey: secretsManagerString('/app/api_key')
}

const { bucketArn, apiKey } = await getConfig({ parameters })

Advanced Usage

import { SSMClient } from '@aws-sdk/client-ssm'
import { SecretsManagerClient } from '@aws-sdk/client-secrets-manager'
import cacheManager from 'cache-manager'
import { localString, ssmString, secretsManagerString, getConfig } from '@pureskillgg/ace'

process.env.BUCKET_ARN_SSM_PATH = '/app/bucket_arn'
process.env.API_KEY_SECRET_ID = '/app/api_key'
process.env.API_ORIGIN = 'https://example.com'
process.env.FOO = 'bar'

const parameters = {
  bucketArn: ssmString('BUCKET_ARN'),
  apiKey: secretsManagerString('API_KEY'),
  apiOrigin: envString('API_ORIGIN'),
  name: localString('FOO')
}

const localParameters = {
  bar: 'baz'
}

const cache = cacheManager.caching()

const { bucketId, apiKey, apiOrigin } = await getConfig({
  parameters,
  localParameters,
  aliases: { ...process.env },
  ssmClient: new SSMClient(),
  secretsManagerClient: new SecretsManagerClient(),
  log: createLogger(),
  cache
})

Installation

Add this as a dependency to your project using npm with

$ npm install @pureskillgg/makenew-jsmodule

Development and Testing

Quickstart

$ git clone https://github.com/pureskillgg/ace.git
$ cd ace
$ nvm install
$ npm install

Run the command below in a separate terminal window:

$ npm run test:watch

Primary development tasks are defined under scripts in package.json and available via npm run. View them with

$ npm run

Source code

The source code is hosted on GitHub. Clone the project with

$ git clone git@github.com:pureskillgg/ace.git

Requirements

You will need Node.js with npm and a Node.js debugging client.

Be sure that all commands run under the correct Node version, e.g., if using nvm, install the correct version with

$ nvm install

Set the active version for each shell session with

$ nvm use

Install the development dependencies with

$ npm install

Publishing

Use the npm version command to release a new version. This will push a new git tag which will trigger a GitHub action.

Publishing may be triggered using on the web using a workflow_dispatch on GitHub Actions.

GitHub Actions

GitHub Actions should already be configured: this section is for reference only.

The following repository secrets must be set on GitHub Actions:

• NPM_TOKEN: npm token for publishing packages.

These must be set manually.

Secrets for Optional GitHub Actions

The docs, version, and format GitHub actions require a user with write access to the repository including access to read and write packages. Set these additional secrets to enable the action:

• GH_USER: The GitHub user's username.
• GH_TOKEN: A personal access token for the user.
• GIT_USER_NAME: The GitHub user's real name.
• GIT_USER_EMAIL: The GitHub user's email.
• GPG_PRIVATE_KEY: The GitHub user's GPG private key.
• GPG_PASSPHRASE: The GitHub user's GPG passphrase.
