Im tryin to get my queries to update using the subscribeToMore function. Im getting lost on why the code is a failing to execute. so far all operations query, mutation and subscribe will work independently.
FRONTEND
export const QUERY_MESSAGES = gql`
query Messages($convoId: ID!) {
messages(convoId: $convoId) {
text
senderId
convoId
createdAt
}
}
`;
export const SUBSCRIBE_MESSAGES = gql`
subscription Messages($convoId: ID!) {
messages(convoID: $convoID) {
text
convoId
}
}
`;
const ActiveChat = ({ currentConvo, me }: any) => {
const { subscribeToMore, data } = useQuery(QUERY_MESSAGES, {
variables: {
convoId: currentConvo,
},
});
return (
<section className="chat-wrapper">
<div className="messages-container">
<Messages
messages={data.messages}
me={me}
subscribeToMessages={() => {
subscribeToMore({
document: SUBSCRIBE_MESSAGES,
variables: { convoId: currentConvo },
updateQuery: (prev, { subscriptionData }) => {
console.log("hit");
if (!subscriptionData.data) return prev;
const newFeedItem = subscriptionData.data.messages;
return Object.assign({}, prev, {
messages: [newFeedItem, ...prev.messages],
});
},
});
}}
/>
<Input currentConvo={currentConvo} />
</div>
</section>
);
};
const Messages = ({ messages, me, subscribeToMessages }: any) => {
useEffect(() => {
subscribeToMessages();
console.log("use effect ran");
});
const formatTime = (time: number) =>
new Date(time * 1000).toLocaleTimeString();
console.log(messages);
return (
messages && (
<div>
{messages.map((message: any, i: number) => {
return message.senderId === me?._id ? (
<SenderBubble
key={i}
text={message.text}
time={message.createdAt}
formatTime={formatTime}
/>
) : (
<OtherUserBubble
key={i}
text={message.text}
time={message.createdAt}
formatTime={formatTime}
/>
);
})}
</div>
)
);
};
BACKEND
const pubsub = new PubSub();
Query: {
messages: async (parent, { convoId }, context) => {
if (context.user) {
return Message.find({ convoId }).sort({ createdAt: "asc" });
}

},
Mutation: {
/// creates a new message using sender id and emits MESSAGE_SENT event
sendMessage: async (parent, { text, convoId }, context) => {
pubsub.publish("MESSAGE_SENT", {
message: { text, convoId },
});
return Message.create({ text, convoId, senderId: context.user._id });

Subscription: {
userActive: {
subscribe: () => pubsub.asyncIterator("ACTIVE_USERS"),
},
message: {
subscribe: withFilter(
() => pubsub.asyncIterator("MESSAGE_SENT"),
(payload, variables) => {
return payload.message.convoId === variables.convoId;
}
),
},
},
tdlr: I think subscribeToMore.updateQuery isn't firing but i don't how to debug
SOLVED: turns out I placed the wrong url and port number while building the client so the ws wasn't connecting.
