# NodeJS - Backend implementation

{% hint style="info" %}
This section describes a full implementation of SIWC in a NodeJS sample app.
{% endhint %}

Although you can chose to make a step by step implementation from scratch, using the open source components, it may be more convenient and faster to download the sample app and follow the video tutorial. In this case, jump direct to the section 5 below.

{% hint style="warning" %}
If you are new to oAuth2, it may be good to first have a look at some generic tutorials. We found this one below particularly relevant.
