            react-native-gifted-chat How to send on pressing return
            Asked 2022-Feb-21 at 11:33

            How do I make the return button on the mobile keyboard send the message instead of creating a new line? I tried using onSubmitEditing in the textInputProps but couldn't get it to work.



            Answered 2022-Feb-21 at 11:33

            You need to implement your own ChatComposer and pass the onSubmitEditing prop in the textInputProps in there. In order to prevent keyboard dismiss you also need to set blurOnSubmit to false.

            Mongodb Mongoose sort and paginate chat messages
            Asked 2022-Feb-07 at 14:43

            I am making a chat app where 10 messages are loaded per page. The messages are sorted from oldest to latest, so the new messages come in bottom and old messages are in top. I tried to use skip() and limit() methods it didnt work.



            Answered 2022-Feb-07 at 14:43

            Since you want to display messages 3 to 12 first, you need to sort using 'desc' instead of 'asc', so as to get the newest messages first. This will give you ["12", "11", ... "4", "3"]. Now all you have to do is to invert this array to get ["3", "4", ... "11", "12"]:

            Testproject Messager with Flutter using Peer-to-Peer Technology
            Asked 2022-Jan-27 at 14:18

            I'm working on a Testproject, where I want to exchange information via peer-to-peer from one Mobile device to another.

            My goal is to make a little chat widget, where when you post a message, you can see it on all devices, which are connected, a bit like this: So if I have one Mobile device, where I send the message, it's seen by all devices.

            The reason why I'm asking for help here, is because I've looked around and found two options for peer-to-peer in Flutter: A faulty example of a peer-to-peer connection in Flutter, with practically no documentation

            A better-documented example of peer-to-peer connection in Flutter, which also doesn't seem to work.

            According to some people, the first option doesn't even work anymore. I've tried both and neither of them managed to achieve what I wanted. It's possible that I don't understand the difference between them 100%.

            With this I don't even know really, how to write the Dart/Flutter code, to test the connection between two devices.

            I have experience with using Sockets and socketstreams on Java, where one device would send something into the socket stream and the other read it out of the socket stream, but there one device was server and one client.

            It would really help me if you could write a simple model, where this peer-to-peer connection works. Because the "documentation" available isn't helping me at all.

            Here is the non functioning code, which I have so far

            There were multiple problems here:

            1. Not all permissions were given, as kindly pointed out by @TheFunk
            2. Huawei P40 Pro doesn't have google services, thus not communicating properly via Peer To Peer
            3. List item
            4. I was using the P2P strategy STAR, instead of cluster, which now seems to work.
            5. My focus on NFC was wrong, because it doesn't matter if the device has NFC or not.
            6. My assumption that both devices need the same userName seems to be wrong. They can be different, as long as they're declared to find each EndPointId.

            Note: This question is one of two, which are about the same nearby_connections library of Flutter.
            For me this question has been solved and if you have trouble finding a working code you should check out this question, where I've posted the entire connection code, which works but does not yet receive packages.

            How does the disconnect event works in socket.io?
            Asked 2022-Jan-12 at 00:53

            I followed a tutorial and was able to copy/build a simple real time web app. I understand everything from the code except for one thing. The 'disconnect' event. I removed most of the code for simplification, but it goes like this:



            Answered 2022-Jan-12 at 00:53

            The disconnect event is a built-in socket.io event that tells you when a client disconnects.

            The socket.io client JavaScript uses the beforeunload event listener on the window, which executes before the tab closes, then sends a "I'm gonna die" message to the server, then vanishes.

            The server can also attempt to ping the client and if nothing returns, oops, disconnected.

            On the other hand, the client can manually disconnect from the server with:

            Perform action on seen/unseen messages with socket.io
            Asked 2021-Dec-31 at 07:26

            What is the best practice to handle seen/unseen messages in a chat room application based on Nodejs/SocketIO/React.

            Consider User1 sends a message to a room. If another user has seen that message, notify all users that the state of message has been seen.

            In my opinion using message brokers can be the better solution instead socket. I actually think that socket should only handle chat messages that are synchronously. but for seen/unseen status I prefer message brokers that are asynchronous. Are there any solutions or best practice in large scale applications?



            Answered 2021-Dec-31 at 07:26

            It's unclear what you have currently tried, meaning that I can only advise solutions in order to achieve your aim.

            To firstly identify that a message was seen, IntersectionObserver is an inbuilt API that detects when an element has entered the viewport, meaning that it is visible, therefore; obviously seen. I have added comments in the code below where you should add a function to call to the server that the message was seen, however, that's up to you to implement.

            Ngfor doesn't actualize on reloading page (Angular + RXJS)
            Asked 2021-Dec-24 at 12:07

            Hi i'm building a chat app with angular for a school project i'm using firebase for my backend and i have an issue with my ngfor.

            For exemple if i reload the page i will see nothing unless i hover my routerlink on my navbar. However sometime it will work after some time on the page without any action

            When i recieve message i need to be on the page to see them ...

            When i reload my page in first time my array is empty this may be what makes the ngfor bug array on reload.

            I'm using ngOnInit() to subscribe :



            Answered 2021-Dec-24 at 11:41

            I think you might need to use the child_added event instead of value in your getMessage method.
            Check if you're receiving data on time in your getMessage method, if not it's most probably, because of the event.
            But one thing that I don't understand is why you're calling emitMessage inside getMessage and also calling it inside your component after getMessage, try to evade that.

            I created a messenger using Python Socket, when I use two clients, for example, when one user leaves the chat, the second user can send 1-2 more messages and after that the server stops accepting messages from other users, that is there is a well-known error Broken pipe 32. I understand the terminology of the error, perhaps the error lies on my server in a While True loop (a loop that includes all the actions that users carry out among themselves), because there is a fabulous code in the form:

            How to handle thousands of messages in a real-time group chat with Firestore?
            Asked 2021-Nov-10 at 14:53

            I need some help with Firestore building a chat app. I've looked at the documentation but I couldn't find the answer I need.

            I'm building a real-time chat (many-to-many) that must handle thousands of messages, and those messages can also be edited, deleted and undeleted. The main problem is that loading all the messages once (as Firebase suggests) and then manage them on the FrontEnd side freezes my frontend application for the huge amount of messages. I tried to do that with the pagination API but I got some edge cases e.g.



            Answered 2021-Nov-10 at 14:53

            Your approach is fine, but it turns out that pagination and realtime updates with a cursor based API lead to some tricky edge-cases.

            You'd have to either remove the duplicate documents based on their ID and then have pages with different sizes, or update the starting point of the second query (and then later queries as you have more pages).

            There are more such edge cases, which is one of the reasons the FirestorePagingAdapter in FirebaseUI doesn't handle realtime updates.

            How do I force the server to receive messages from the client and display the message: "{name} send message: {data}"? For example, a user sends a message to another user, and when a user named John sends the message "Hello Alice, how are you?", The server will be displayed at this point - John will send a message: Hello Alice, how are you?
