Request Handlers in ExpressJS

Question

Node.js

Problem following - there is a request handler with huge logic. Processing lasts from 5 to 20 minutes. If the client closes the connection, express stops executing the handler. How can I tell him not to do it? Those. after the connection is closed by the client, do not stop the handler.

Answer 1

Are you kidding me? Node.js is asynchronous. Fully. Revisit the logic.
You can do it like this, for example:

app.get("/", function(req, res){
 setTimeout(function(result){
  // some logic
  console.log('finished');
 },1000*5);
 res.end('Processing..');
});
