Socket.IO

问题 i am trying to implement a 1-1 private messaging feature inside my app, where 2 users can exchange messages live if they are both on the chat screen at the same time and if not the messages get stored in my postgres database and when the user opens the chat again they are loaded. Currently with my code, when both users chat are open, when i try sending a message, the message does not get sent live i need to refresh the app in order for the chat to update. I think my socket is working since my

问题 A user of my system will access a page to pull lots of data, at least 500 records, from server Foo . Once 50 records have been gathered, Express will begin to render the page to display the first 50 records to the user (only the first 50 records need to be displayed initially). Once the system has pulled all 500 records from Foo I want to send the user a message letting them know that the operation is complete. My idea is to call the socket emit function once the processing is complete,

Think of it like chat messenger. You only show the messages you recieve between those two users. I can do one

问题 In my express app, generated with express-generator , I want to use the io of socket.io in some other controller files to emit data to client sockets. My approach is below, but I get the following error with that. It would be a great favor if someone can help me in this case. (node:11376) UnhandledPromiseRejectionWarning: TypeError: io.emit is not a function at F:\backend\controllers\LessonController.js:169:9 In the express apps, generated by express-generator , the process of creating the

问题 I am jumping in on a project with some socket issues over SSL and Cloudflare... I know.. I have read about 50 different stack overflow posts and 200 blog posts to try to figure this out. The project works on my local dev server/computer just fine... I think I am on the right track - But could use some help/pointers if ya'll can. First, I thought it was weird that the /socket-io/ proxy_pass was at port 6379, the same as redis... Maybe it should be? When this was set at 6379, the socket
