Difference between app.use('*') and app.all('*') in Express

Question

Is there a difference between

app.use('*', function (req, res, next) {

});

and...

app.all('*', function (req, res, next) {

});

Answer 1

app.all() references the application router like post or get, while app.use() simply references the applications middleware. app.use() is better for more globally defined statements that you want persistent through your entire application.
