uncaughtException

[Angelo Chen]

Hi,

got some code to test out uncaught Exception, why following code not
got caught in the listener?

app.get "/uncaughtException", (req, res) ->
throw new Error("uncaught error");
res.send 'uncaughtException'

process.addListener "uncaughtException", (err) ->
console.log("Uncaught exception: " + err)

Express might be catching that error. Iirc, it picks up errors you throw directly in middleware/routes. (As well as passing errors with next().)

If you throw an error indirectly though, it shouldn't be caught by express' error handler, and be picked up by your handler instead:

app.get("/uncaughtException", function (req, res) {
        setTimeout(function () {

                throw new Error("uncaught error");

        }, 1000);

        res.send('uncaughtException');

});

process.addListener("uncaughtException", function (err) {
        console.log("Uncaught exception: " + err);

});
