Currently working on a 1:1 live chat messenger. when i send a message its shows up at the bottom of chat where i want it to, but upon page refresh it returns to the top of the messenger. How do i set it so newest message is always at the bottom? heres some code i believe the problem is in setActiveChat or or addMessageToConversation.
const sendMessage = (data, body) => {
socket.emit("new-message", {
message: data.message,
recipientId: body.recipientId,
sender: data.sender,
});
};
const postMessage = async (body) => {
try {
const data = await saveMessage(body);
if (!body.conversationId) {
addNewConvo(body.recipientId, data.message);
} else {
addMessageToConversation(data);
}
sendMessage(data, body);
} catch (error) {
console.error(error);
}
};
const addNewConvo = useCallback(
(recipientId, message) => {
setConversations(previousState => previousState.map(convo => {
if (convo.otherUser.id === recipientId) {
convo.messages.push(message)
convo.latestMessageText = message.text;
convo.id = message.conversationId;
return convo
}
return convo
}))
},
[setConversations],
);
const addMessageToConversation = useCallback(
(data) => {
// if sender isn't null, that means the message needs to be put in a brand new convo
const { message, sender = null } = data;
if (sender !== null) {
const newConvo = {
id: message.conversationId,
otherUser: sender,
messages: [message],
};
newConvo.latestMessageText = message.text;
setConversations((prev) => [newConvo, ...prev]);
}
conversations.forEach((convo) => {
if (convo.id === message.conversationId) {
const convoCopy = { ...convo };
convoCopy.messages.push(message);
convoCopy.latestMessageText = message.text;
return convoCopy;
} else {
return convo;
}
});
setConversations([...conversations]);
},
[setConversations, conversations],
);
const setActiveChat = useCallback((username) => {
setActiveConversation(username);
}, []);
