Azure Key Vault

Node library for handle Azure Key Vault, abstracts secrets management by project, environment and group when vault is shared. Also, this library handles nested JSON structures.

How To Use 💡

Should be initialized with AzureKeyVault in two ways as:

import { AzureKeyVault } from '@achs/azure-key-vault';

// initializes azure key vault with default credentials
// azure cli, environment variables, etc.
// see https://www.npmjs.com/package/@azure/identity

// execute `az login` if you're using az cli
const keyVault = new AzureKeyVault('https://my-key-vault.vault.azure.net', {
	project: 'my-project',
	group: 'web',
	env: 'dev',
});

import { AzureKeyVault } from '@achs/azure-key-vault';

// initializes azure key vault with SPN credentials
const keyVault = new AzureKeyVault(
	'https://my-key-vault.vault.azure.net',
	{
		project: 'my-project',
		group: 'web',
		env: 'dev',
	},
	{
		clientId: 'f176a774-239e-4cd3-8551-88fd9fb9b441',
		clientSecret: 'WyBwkmcL8rGQe9B2fvRLDrqDuannE4Ku',
		tenantId: '9dba8525-be64-4d10-b124-e6f1644ae513',
	}
);

and used as below:

import { AzureKeyVault } from '@achs/azure-key-vault';

// initialized here ...

async function main() {
	await keyVault.setAll({
		SECRET1: 'my secret 1',
		SECRET2: 'my secret 2',
		otherConfig: {
			SECRET3: 'my secret 3',
		},
	});

	const mySecret2 = await keyVault.getInfo('SECRET2');
	console.log(mySecret2);
	// name is 'my-project-dev-web-secret2' and value 'my secret 2'

	const mySecret3 = await keyVault.getInfo('otherConfig:SECRET3');
	console.log(mySecret3);
	// name is 'my-project-dev-web-otherConfig--secret3' and value 'my secret 3'

	const mySecrets = await keyVault.getFor({
		SECRET1: null,
		SECRET2: 'default value',
		otherConfig: {
			SECRET3: null,
		},
		SECRET4: 'def for secret 4',
	});
	console.log(mySecrets);
	// prints { SECRET1: 'my secret 1, SECRET2: 'my secret 2', otherConfig: { SECRET3: 'my secret 3' }, SECRET4: 'def for secret 3' }
}

main();

You can initialize key vault with environment variables as:

import { AzureKeyVault } from '@achs/azure-key-vault';

...
process.env.AZURE_KEY_VAULT_URI = 'https://my-key-vault.vault.azure.net';
process.env.AZURE_CLIENT_ID = 'f176a774-239e-4cd3-8551-88fd9fb9b441';
process.env.AZURE_CLIENT_SECRET = 'WyBwkmcL8rGQe9B2fvRLDrqDuannE4Ku';
process.env.AZURE_TENANT_ID = '9dba8525-be64-4d10-b124-e6f1644ae513';
...

// initializes azure key vault
const keyVault = new AzureKeyVault({
	project: 'my-project',
	group: 'web',
	env: 'dev'
});

...

Functions

Library has functions for manage key vault secrets.

i You can use ':' for nested path, (i.e. car:props:name) i You can prefix your key with '&' for project shared secret, (i.e. car:props:$name)

• get: returns secret value.

const value = await keyVault.get('my-secret');

• getInfo: returns secret info.

const info = await keyVault.getInfo('my-secret');

• set: inserts or updates secret value.

const info = await keyVault.set('my-secret', 'my secret value');

• delete: deletes a secret.

const deletionInfo = await keyVault.delete('my-secret');

• purge: purges a deleted secret.

const info = await keyVault.purge('my-secret');

• restore: restores a deleted secret.

const restoredInfo = await keyVault.restore('my-secret');

• getAll: gets all secrets for the project, env and group.

const listOfSecrets = await keyVault.getAll();

• getFor: (faster than getAll) gets all secrets for the project, env and group defined in input object. In order to get array correctly deserialized, use [] as default value instead of null or undefined.

let secrets = {
	'$global-var': null,
	'my-secret': null,
	'my-secret-2': 'default value',
	'my-secret-group1': {
		'my-secret-3': null,
	},
	// in case of array type variable, default must be
	// an array (or empty array) for correct deserialize
	'my-array-secret': [],
};

const listOfSecrets = await keyVault.getFor(secrets);

• setAll: insert or updates a set of secrets.

let secrets = {
	'$global-var': 'my shared secret',
	'my-secret': 'my secret',
	'my-secret-2': 'my secret 2',
	'my-secret-group1': {
		'my-secret-3': 'my secret 3',
	},
	'my-array-secret': ['a', 'b', 'c'],
};

const listOfProperties = await keyVault.setAll(secrets);

• deleteAll: deletes every secrets for the project group.

const info = await keyVault.deleteAll();

• purgeAll: purges every deleted secrets for the project group.

const info = await keyVault.purgeAll();

• restoreAll: restores every deleted secrets for the project group.

const info = await keyVault.restoreAll();

Commands

Library has node commands for use with npm. Every commands needs credentials arguments for connect to key vault.

You should define your npm script command in package.json as:

// package.json
{
	...,
	"scripts": {
		...,
		"akv": "akv --project=my-project --group=web --tenant=9dba8525-be64-4d10-b124-e6f1644ae513",
		...
	},
	...
}

• getFor: writes a file with secrets as JSON, using a JSON file as secrets structure definition.

foo@bar:~$ npm run akv getFor -- \
	--env=dev \
	--uri=https://my-key-vault.vault.azure.net \
	--spn=f176a774-239e-4cd3-8551-88fd9fb9b441 \
	--password=WyBwkmcL8rGQe9B2fvRLDrqDuannE4Ku \
	--file=secrets-structure-definition.json \
	--output=my-secrets.json \
	--override

• getAll: writes all secrets (for project, group and env) in a JSON file.

foo@bar:~$ npm run akv getAll -- \
	--env=dev \
	--uri=https://my-key-vault.vault.azure.net \
	--spn=f176a774-239e-4cd3-8551-88fd9fb9b441 \
	--password=WyBwkmcL8rGQe9B2fvRLDrqDuannE4Ku \
	--output=my-secrets.json \
	--override

• publish: creates or updates secrets (for project, group and env) in key vault from a JSON file.

foo@bar:~$ npm run akv publish -- \
	--env=dev \
	--uri=https://my-key-vault.vault.azure.net \
	--spn=f176a774-239e-4cd3-8551-88fd9fb9b441 \
	--password=WyBwkmcL8rGQe9B2fvRLDrqDuannE4Ku \
	--file=my-secrets.json

• clear: deletes all secrets (for project, group and env) in key vault.

• restore: restores all deleted secrets (for project, group and env) in key vault.

Linting 🧿

Project uses ESLint, for code formatting and code styling normalizing.

• eslint: JavaScript and React linter with Airbnb React base config and some other additions.

For correct interpretation of linters, is recommended to use Visual Studio Code as IDE and install the plugins in .vscode folder at 'extensions.json', as well as use the config provided in 'settings.json'
