Difference between app.all('*') and app.use('/')

Question

Is there a useful difference between app.all(\'*\', ... ) and app.use(\'/\', ...) in Node.JS Express?

Answer 1

With app.use(), the "mount" path is stripped and is not visible to the middleware function:

app.use('/static', express.static(__dirname + '/public'));

Mounted middleware functions(express.static) are not invoked unless the req.url contains this prefix (/static), at which point it is stripped when the function is invoked.

With app.all(), there is no that behavior.
