A CoinMarketCap API proxy for injecting headers and avoiding CORS issues

This is a proxy HTTP server for the CoinMarketCap API, primarily used for injecting an authorization header into proxied requests, so that client side applications can't see private secrets.

make sure to add a .env file that exports a COINMARKETCAP_API_KEY variable and a TARGET variable.

The TARGET is the server where requests should be forwarded.

You can also specify the PORT to listen on via the PORT .env var

Notes

Steps we took to get certs working.

In our ubuntu machine on digital ocean, we run:

$ sudo add-apt-repository ppa:certbot/certbot
$ sudo apt-get update
$ sudo apt-get install certbot
$ certbot certonly --manual

We run the server: npm run start, server sould be listening on port 80.

Then we the certbot will generate a challenge file for us. We bring down the server, and add the file inside /server/.well-known/acme-challenge/<file>

Then we bring the server back online with npm run start

Then we accept the certbot challenge, which hits our server and generates a certificate.

Finally, we bring the server down one more time, and restart it (because we now have the proper certs). HTTPS is enabled!
