In this article/tutorial, we are going to create an API Proxy Server using NodeJS, and the main reason behind this is to show you how to hide public API keys and not expose them in the public like I was doing in the past. All of us have created an application once just to get to know a new library or a framework, and the best way to achieve this is to use an open API (like TMDB).

Most of these open APIs require adding the API key in the request URL or in the headers before making the request. Either way, the API key can be stolen and used by people that are not actually own this key. As a result, you may end up with a suspended account, or your application not work as you’ve expected it to.
