# Tutorial

## Getting started

### Add the package to your project

Using NPM:

```
npm install {{site.data.lib.package}}
```

Using Yarn:

```
yarn add {{site.data.lib.package}}
```

### Write some code

We recommend using Typescrypt or ES6 modules.
Import needed types from the {{ site.data.lib.package }} module,
for example:

```
import { JSONWebToken, BioSample } from '@digitalpersona/core';
import { FingerprintsAuth } from '@digitalpersona/authentication';

...
async submitFingerprints(samples: BioSample[], identity?: JSONWebToken)
: JSONWebToken | null
{
    try {
        const api = new FingerprintsAuth(...);

        const token = await (
            identity
                ? api.authenticate(identity, samples)
                : api.identify(samples)
        );
        return token;
    }
    catch (error) {
        handleError(error);
        return null;
    }
}
```

## Using Components

{% capture apiDocsBaseUrl %}{{site.data.lib.git}}/{{site.data.lib.repo}}/blob/master/dist/api/docs/authentication{% endcapture%}
