Use process.on('uncaughtException to show a 500 error page

error-handling, express, node.js

Solution

I don't think you can from within the `uncaughtException` do a response since that could happen even when there is no request occurring.

Express itself provides a way to handle errors within routes, like so:

app.error(function(err, req, res, next){
    //check error information and respond accordingly
});

Problem

I'm developing an express app. I currently have the following in my server.js ``` process.on('uncaughtException', function (err) { console.log( "UNCAUGHT EXCEPTION " ); console.log( "[Inside 'uncaughtException' event] " + err.stack || err.message ); }); ``` Which stops the server crashing every time there's an error, however, it just sits there... is it possible to instead of console.log, to send a 500 error page with the error details?
