title: Front end = ..nginux.. = Back end?
body: <p>My question might seem dumb, but im highly uneducated on this topic, but i really want to learn how this is all working.</p>
  
  <p>For the sake of example let me provide you with a scenario.</p>
  
  <p>I have front end built with react, the website has all the required http requests and sends everything that is required to my server. The server is running on nodeJs(express).</p>
  
  <p>The website and a server are working just fine, both of them are on different ports. Front end is on localhost:3000, and back-end is on localhost:8000.</p>
  
  <p>Recently i started spending a considerable amount of time, trying to understand how real applications work and what needed to deploy them. At this moment i came across a few articles that suggest to use a proxy server that can be like a "bridge"(maybe for secuirty reasons (my guess)).</p>
  
  <p>So could somebody give me insights to understand this concept?</p>
  
  <p>Im sorry if the question might seem a bit dumb to you, but its hard to find good information on the inet about it.</p>
  
  <p>If i understand this concept completely wrong and there is nothing in this sort, just comment below and i will delete this thread.</p>
