title: CORSS with proxy url
body: <p>I am making a react application where I use an API. However, I couldn't make the API work and I opted for CROSS, using a proxy URL (<a href="https://yacdn.org/proxy/" rel="nofollow noreferrer">https://yacdn.org/proxy/</a>). Now I can retrieve my desired information from the API but after some time my application crashes.
  I get an error saying:</p>
  
  <p>Access to fetch at '<a href="https://yacdn.org/proxy/https://apps.des.qld.gov.au/species/?op=getspecies&amp;kingdom=animals&amp;family=Macropodidae" rel="nofollow noreferrer">https://yacdn.org/proxy/https://apps.des.qld.gov.au/species/?op=getspecies&amp;kingdom=animals&amp;family=Macropodidae</a>' from origin '<a href="http://localhost:3000" rel="nofollow noreferrer">http://localhost:3000</a>' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.</p>
  
  <p>I tried using mode: 'no-cors'. I am not allowed to use <a href="https://chrome.google.com/webstore/detail/allow-control-allow-origi/nlfbmbojpeacfghkpbjhddihlkkiljbi/related?hl=en" rel="nofollow noreferrer">Chrome-extension</a> and was told to come up with a backend solution that just forwards (proxies) the call to the API and returns the result</p>
  
  <p>How can I solve this? Any hint will be appreciated.</p>
