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).

[AWS SSM parameter store]: https://aws.amazon.com/systems-manager/
[AWS Secrets Manager]: https://aws.amazon.com/secrets-manager/
[Pino]: https://getpino.io/
[mlabs-logger]: https://github.com/meltwater/mlabs-logger
[cache-manager]: https://github.com/BryanDonovan/node-cache-manager

## Basic Usage

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

```js
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

```js
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
```

[npm]: https://www.npmjs.com/

## 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
```

[source code]: https://github.com/pureskillgg/ace

### 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
```

[Node.js]: https://nodejs.org/
[Node.js debugging]: https://nodejs.org/en/docs/guides/debugging-getting-started/
[npm]: https://www.npmjs.com/
[nvm]: https://github.com/creationix/nvm

### Publishing

Use the [`npm version`][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].

[npm-version]: https://docs.npmjs.com/cli/version
[workflow_dispatch on GitHub Actions]: https://github.com/pureskillgg/ace/actions?query=workflow%3Aversion

## 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.
