Corsaro 🏴‍☠️

A simple reverse proxy to allow cors request.

Useful for local development or testing. Don't use it in production.

Run with Docker

To proxy a remote service, simply run:

docker run -p 1337:1337 emanuelelongo/corsaro http://a-service-not-allowing-cors.com

Now the service is reachable to http://localhost:1337 allowing cors.

If the service you need to proxy runs on localhost, for example on port 8080, then use host.docker.internal to refer it inside Docker:

docker run -p 1337:1337 emanuelelongo/corsaro http://host.docker.internal:8080

Build your own executalbe

If you need an executable that can be run without Docker or any dependencies you can build it within a Go environment.

git clone https://github.com/emanuelelongo/corsaro.git
cd corsaro
go mod download
go build -o ./build/corsaro ./src

Change default port

By default Corsaro listen on 1337 port but you can override this setting using an additional argument:

corsaro http://a-service-not-allowing-cors.com 8080

If running with docker remember to map the port accordingly:

docker run -p 8080:8080 emanuelelongo/corsaro http://a-service-not-allowing-cors.com 8080
