"this" inside a service route

[biziosan]

I am implementing an RPC service. Its requests need several things to be executed, so the server is a class. I don't know how to use the "this" handle in the body of the requests. Any ideas? What am I missing?

class Server {
    private _sentence: string;
    private routes(router: ConnectRouter) {
        router.service(ElizaService, {
            say(req: SayRequest) {
                return { sentence: this._sentence };
            }
        }
    }
}

The solution is:

class Server {
    private _sentence: string;

    constructor() {
        const self = this;
        const handler = connectNodeAdapter(
            {
                routes: function(router: crpc.ConnectRouter) {
                    router.service(ElizaService, {
                        say(req: SayRequest) {
                            return { sentence: self._sentence };
                        }
                    });
                }
            }
        );
    }
}```

An alternative is to implement services (not the entire server) with classes. You can find an example here.
