You are going to want to extend the base
class.
export declare class base {
/**The underlying proxy function. Returns a function that can be used to kill the connection
* @param socket The connection that should be forwarded
* @param handler The function for handling resolving the hostname and port that should be proxied to.
* Given here as a function to allow for dynamic allocation
*/
proxy(socket: Duplex | TLSSocket, handler: (host: string) => {
prxy: string;
port: number;
}): Promise<() => void>;
/**Used to upgrade connections. Mainly for HTTPS to HTTPS communication
* @param socket The outgoing socket that is used to forward messages from the client
*/
protected upgrade(socket: Socket): Socket | TLSSocket;
/**Modifies the underlying header of a sent request
* @param header The raw header. It is given in this format to keep things speedy.
* Do note that removing the white spaces around the header is not recommended in the slightest degree.
*/
protected modHeader(header: string): string;
}
Furthermore, after extending the base class you are going to want to override the upgrade and modHeader functions.
The modHeader function allows you to modify the raw header of a proxied request. Do note that adding whitespaces at the end of a request can cause it to fail.
This function can be overwritten if you are trying to do HTTPS to HTTPS communication/proxying or need to change something about the proxied port.
The lib is still seeing development. Hope onto the discord to suggest changes.
