localhost-cors-proxy

localhost-cors-proxy

A proxy that binds to 127.0.0.1:N and reverse proxies to forwardurl, adding a set of various CORS headers to enable CORS (and therefore the javascript fetch api in browser). I developed this to help with testing local react apps that use fetch to talk to APIs elsewhere.

Security notice

DO NOT RUN THIS ON ANY UNTRUSTED NETWORK, YOU FOOLS.

A Very Special Note When Using as a Passthrough in a node.js Process and Accessing via Chrome

HTTPS=true npm run start, Chrome now validates CORS out of process and only handles HTTPS now.

Using

• go build proxy.go
• ./proxy -listenport 8000 -forwardurl http://localhost:8888
