This is the backend plugin that enables proxy definitions to be declared in, and read from, app-config.yaml.

Relies on the http-proxy-middleware package.

This backend plugin can be started in a standalone mode from directly in this package with yarn start. However, it will have limited functionality and that process is most convenient when developing the plugin itself.

The proxy is already installed in the Backstage backend per default, so you can also start up the full example backend to experiment with the proxy.

yarn workspace example-backend start
