I have two separate apps. One of them is a UI web application written with pure JS, the other one is console application written by C#.
Currently I'm calculating some variables (which can not done in JS because of browser limitations) with C# console app, then it's writing results to a txt file.
Then I read the file with JS application to bring results to UI. But the variable often changes in milliseconds and writing results to disk and retrieving it again is pretty slow.
What can I do? Any suggestions?
The console application is effectively a server. Communicating between a web app and a server by means of a local text file is, well, unconventional! If this is not just for your own use on the one machine, it will be very difficult to deploy for another user. Write a small server application and communicate with it the usual way, i.e, by posting the data to the server's IP address and receiving the server's response. You can remove any connection latency (after the initial connection) by communicating over websocket.
