Websocket connection closed when browser lost internet connection



Iam trying to implement webrtc communication in my project. I have used appr.tc code base for development. The codebase contains two separate websocket implementation for chrome&firefox browser.


if (isChromeApp())
this.websocket_ = new RemoteWebSocket(this.wssUrl_, this.wssPostUrl_);
else
this.websocket_ = new WebSocket(this.wssUrl_);



RemoteWebSocket


var RemoteWebSocket = function (wssUrl, wssPostUrl)
this.wssUrl_ = wssUrl;
apprtc.windowPort.addMessageListener(this.handleMessage_.bind(this));
this.sendMessage_( action: Constants.WS_ACTION, wsAction: Constants.WS_CREATE_ACTION, wssUrl: wssUrl, wssPostUrl: wssPostUrl );
this.readyState = WebSocket.CONNECTING;
;
RemoteWebSocket.prototype.sendMessage_ = function (message)
apprtc.windowPort.sendMessage(message);
;
RemoteWebSocket.prototype.send = function (data)
if (this.readyState !== WebSocket.OPEN)
throw "Web socket is not in OPEN state: " + this.readyState;

this.sendMessage_( action: Constants.WS_ACTION, wsAction: Constants.WS_SEND_ACTION, data: data );
;
RemoteWebSocket.prototype.close = function () ;
RemoteWebSocket.prototype.handleMessage_ = function (message)
if (message.action === Constants.WS_ACTION && message.wsAction === Constants.EVENT_ACTION)
if (message.wsEvent === Constants.WS_EVENT_ONOPEN)
this.readyState = WebSocket.OPEN;
if (this.onopen)
this.onopen();

else
if (message.wsEvent === Constants.WS_EVENT_ONCLOSE)
this.readyState = WebSocket.CLOSED;
if (this.onclose)
this.onclose(message.data);

else
if (message.wsEvent === Constants.WS_EVENT_ONERROR)
if (this.onerror)
this.onerror(message.data);

else
if (message.wsEvent === Constants.WS_EVENT_ONMESSAGE)
if (this.onmessage)
this.onmessage(message.data);

else
if (message.wsEvent === Constants.WS_EVENT_SENDERROR)
if (this.onsenderror)
this.onsenderror(message.data);

console.log("ERROR: web socket send failed: " + message.data);






;



I don't want to close the WebSocket connection During internet connectivity loss(within 3 minutes), The RemoteWebSocket is working fine with chrome browser. There is no closed event occurred when connectivity loss within 3 minutes. But in firefox, WebSocket connection will be closed immediately.



Is there any way to delay the close event in javascript websocket libray?





Check the documentation of the WebSocket library you are using, if it has an option to change the ping interval or timeout related option to delay the reporting of websocket connection.

It's happening because web socket connections are designed that way to get disconnected when there's no network. I understand that you do not want your socket to get disconnected and for that you will have to write logic to reconnect once the network connection resumes. So basically you will have to keep track of the data structures associated with your websocket and restore it when a re-connection is attempted.

Firebase Auth - with Email and Password - Check user already registered

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas

Dynamically update html content plain JS

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12

How to determine optimal route across keyboard

Image
Clash Royale CLAN TAG #URR8PPP How to determine optimal route across keyboard I'm trying to automate the typing process in a video game. Players are given an on-screen QWERTY keyboard layout that they can navigate with the control stick (up, down, left, right) in order to select a letter to type. I was wondering if there was a module for Python (or some other resource I could explore) that would help my program find a path across the keyboard as it types each letter in a given message. In other words, if the first letter typed was "A" and the next letter was "B", the module would know that the program should move 1 space down on the keyboard and 4 spaces to the right. Currently, I have the program resetting to the "G" key after each letter is typed (allowing me to use fixed-directions as the program parses each character in the desired message). As you can imagine, this is quite inefficient and defeats the purpose of automating the typing in the fir
