Express.js Proxy for UPC Database API

This project is an Express.js-based proxy for the UPC Database API. The proxy serves as a middleman to handle custom headers, as the UPC Database API does not accept lowercase headers. Additionally, the proxy server is secured from unknown agents by requiring a PROXY_TOKEN, which is passed in the x-upcdp-authorization header.

Features

• Custom Header Handling: Ensures compliance with UPC Database API's case sensitivity requirements for headers.
• Proxy Server Security: Only requests that include the correct PROXY_TOKEN in the x-upcdp-authorization header are processed, protecting the server from unauthorized access.

Requirements

• Node.js and npm installed on your machine.
• An active account and API key from the UPC Database.
• A secure PROXY_TOKEN for authentication to the proxy server.

Setup

1. Clone the repository:

   git clone https://github.com/Helmare/upcdatabase-proxy.git
   cd upcdatabase-proxy

2. Install dependencies:

   npm install

3. Create an .env file with your proxy token:

   PROXY_TOKEN=your_secure_proxy_token_here

4. Run the proxy server:

   npm start

Usage

To use the proxy, include the x-upcdp-authorization header with the correct PROXY_TOKEN when making requests. Only authorized requests will be forwarded to the UPC Database API.

Example Request

curl -X GET http://localhost:3000/api/upc/{your-upc-code} \
  -H "x-upcdp-authorization: your_secure_proxy_token_here"

This request will be forwarded to the UPC Database API with the correct headers and processed if the provided token matches the one defined in the proxy.
