Handling connection lost

[shtanaka]

I am looking for a away to handle errors when the server loses the connection. I tried to use the applyAfterware, however it does not catch it since there is no response from the server. I always get the following error message in console:

failed: Error during WebSocket handshake: net::ERR_INVALID_HTTP_RESPONSE

What is the best way to catch that kind of error using apollo-phoenix-websocket?

I guess you'd have to create the socket instance yourself (const socket = new Socket() from the phoenix-js library) and then give that socket to APW using the socket: option, that way you can attach your own error handlers to the socket.

I couldn't make it work using socket: option. I used Socket: instead and passed the function. It worked as following:

const networkInterface = createNetworkInterface({
  uri: WS_URI,
  Socket: (uri, options) => {
    const socket = new Socket(uri, options);
    socket.onOpen(() => {
       // handle open
    });
    socket.onError(() => {
       // handle error
    });
    return socket;
  }
})

Thanks for the help 👍
