Data Stream Express.JS Native Auth Wrapper Template

This is a working API template to implement an "Origin Data Stream API Endpoint" that is protected with MultiversX Native Auth. This "Origin Data Stream API Endpoint" can host private, personalized data about the caller or Data NFT itself. e.g., NFT or caller address trade data or historical data. The "Origin Data Stream API Endpoint" can then be used as the "Data Stream URL" on a Data NFT during minting, and only the verified holder of the Data NFT can then access this data.

Do I need Native Auth protection on my Data Stream?

The Data NFT is already protecting the origin of your Data Stream URL thanks to the abstraction encryption provided by the Data Marshal. What this means is that no one should be able to see the plaintext URL of your Data Stream origin. However, in some instances, you may still want an "extra layer" or protection for your Origin Data Stream URL in the event the URL is discovered or shared by someone with "internal" knowledge of it (e.g., dev team). This is where Native Auth protection helps, as it puts the origin Data Stream URL in "protected public mode."

Quick start

1. Run npm install in the project directory
2. Look for the NativeAuthServer({..}) and update as needed

Run API locally

1. Run the API

npm start

2. You can access these endpoints

http://localhost:3000/health-check
http://localhost:3000/datastream

The datastream endpoint will need a Native Auth token sent in as a Bearer Authorization header like so:

curl --location 'http://localhost:3000/datastream' --header 'Authorization: Bearer ZXJk...d39676fc0f'

You should then see the swagger portal on http://localhost:3000/, where you can test your API.
