# azure-devops-npm-auth

Uses the [OAuth 2 device code flow](https://docs.microsoft.com/en-us/azure/active-directory/develop/v2-oauth2-device-code) to authenticate against the Azure DevOps artifact private registry.

## Why? 🤔

Microsoft provides the [vsts-npm-auth](https://www.npmjs.com/package/vsts-npm-auth) package for this task but sadly, it's not cross-platform and doesn't automatically handle token refresh.

There's also [better-vsts-npm-auth](https://www.npmjs.com/package/better-vsts-npm-auth) which solves these issues but requires manual setup (not ideal for a dev team) and authentication through a web app, which in my opinion isn't the best flow to use in the command line.

The **azure-devops-npm-auth** solves all these problems mainly by using the [OAuth 2 device code flow](https://docs.microsoft.com/en-us/azure/active-directory/develop/v2-oauth2-device-code). Once authenticated, access and refresh tokens are then stored in the user's personal .npmrc file, keeping them secure and out of any code repository.

## Installation 💪

Simply run `npm i azure-devops-npm-auth --save-dev`.

## Usage 🤷‍♂️

First, add a pre-installation script to your `package.json` file like so:
```javascript
"scripts": {
"preinstall": "azure-devops-npm-auth"
...
},
```

Then, setup the project repository in the `.npmrc` file as documented in the Azure DevOps npm feed connection page:

When installing packages using `npm i`, the preinstallation script will be executed and ask you to login using a device code:

Follow the instructions to login and authenticate npm to the Azure DevOps private feed. The following installation should be able to use the **refresh token** and automate the task of authenticating:

## Advanced Usage 🧙‍♂️

If you want to use your own Azure Active Directory application, it's possible to specify the `client_id` and `tenant_id` arguments:

```javascript
"scripts": {
"preinstall": "azure-devops-npm-auth --client_id='xxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' --tenant_id='xxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx'"
...
},
```

*Note: If your Azure Active Directory application is configured to be multitenant, `tenant_id` can also be `common` (is the default; Work and school accounts or personal Microsoft accounts), `consumers` (personal Microsoft accounts) or `organizations` (work and school accounts)*.

When creating your own Azure Active Direction application, under the authentication section, you need the configure it to be a public application:

![aad public app](https://i.imgur.com/VeL9cGe.png)

You also need to add the required API permissions to have '`Azure DevOps user_impersonation`' and '`Microsoft Graph User.Read`':

### register-azure-devops-npm-auth.ps1

To automate the creation of the above AD app registration in *your* AD tenant:

1. Ensure you have installed [azure-cli](https://docs.microsoft.com/en-us/cli/azure/install-azure-cli)
2. Open a powershell core prompt (minimum version 6.1)
3. Run `./register-azure-devops-npm-auth.ps1 -Login -InfA Continue`

This will open your default browser where you will need to login to Azure with credentials that has the Azure AD 'Global administrator' RBAC role

### Continuous integration

To disable authentication within CI environments add the `--ci` flag which skips authentication when the `TF_BUILD` environment variable is set (which is automatically set in Azure DevOps build pipelines):
```javascript
"scripts": {
"preinstall": "azure-devops-npm-auth --ci"
...
},
```
It's also possible to specify a custom environment variable:
```javascript
"scripts": {
"preinstall": "azure-devops-npm-auth --ci=MY_CUSTOM_VARIABLE"
...
},
```

### Project Base Path

You can pass in a path to customize the directory to look in for the project's .npmrc file. The default value is the current working directory:

```javascript
"scripts": {
"preinstall": "azure-devops-npm-auth --project_base_path=./configs"
...
},
```

*Note: this is the path to the directory that contains the .npmrc file, meaning you do **not** need to specify the .npmrc in the path.*

## Special Thanks 👏

I have to give thanks to the author(s) of [better-vsts-npm-auth](https://www.npmjs.com/package/better-vsts-npm-auth) which was a big inspiration of mine for this project. Also, thanks to [openid-client](https://www.npmjs.com/package/openid-client) for simplifying the process of integrating the OAuth device code flow to the code.
