Making a THIRD PARTY WIDGET using nodejs

I am making a website which will give the user their client-id, client-secret. With that, they can access the data from my website using a javascript widget. After a lot search, I came upon that I will make my API using laravel. Now that, I am on my widget project. I am making it with NODEJS.

Is my choice of using laravel for my API and NODEJS for the widget is right? Is it correct to use laravel API with NODEJS to make a widget? Is it possible to make third party widget with NODEJS?

NOTE: Oauth2 is also been used in my API to protect my data. Will it work well with NODEJS.

What am I not understanding is how to start up my widget with NODEJS or with any other language?

So many questions are in my mind . Thanks for any help.
