CORS-Anywhere is a Node.js package that adds CORS headers to a proxied request. This is useful when the API provider does not natively support CORS. Without altering the headers, a request to such a provider would cause an error and prevent the request from being fulfilled.

Tip: You can test out the server in this repo locally by using ports 3000 or 5000 in your application and prepending https://proxy-ibmasyzzya-uc.a.run.app/ to your API request like this. However, if you want to use for a hosted website, then follow the implementation steps below.

The server can be implemented in one of three ways. Is is recommended to use Firebase.

Navigate to the heroku directory and follow the steps within the README.md therein. Note that Heroku will withdraw provision of free Dynos on 28th of November 2022. The cost will be $7 per Dyno per month thereafter.

Navigate to the functions directory and follow the steps within the README.md therein. This is the recommended implementation due to the issues outlined in the others above and below.

Navigate to the railway directory and follow the steps within the README.md therein. Unfortunately the free allowance gets reached before the end of the month, so best to go with Firebase.
