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

Two differences all above answers don't metion.

The fisrt one: app.all accepts a regex as its path parameter. app.use does NOT accept a regex.

The second one: app.all(path,handler) or app[method](path,handler),handler's path must be same to all's path. This is,app[method]'path is complete.

app.use(path,hanlder),if use's path is complete,the hanlder's path must be '/'.if the use's path is the start of the complete path,the handler path must be the rest of the complete path.

 app.use('/users', users);

  //users.js:  the handler will be called when matchs `/user/` path
      router.get('/', function(req, res, next) {
      res.send('respond with a resource');
    });
  // others.js: the handler will be called when matchs `/users/users` path
      router.get('/users', function(req, res, next) {
      res.send('respond with a resource');
    });

app.all('/users', users);

//others.js: the handler wil be called when matchs `/`path
router.get('/', function(req, res, next) {
     res.send('respond with a resource');
});
//users.js: the handler will be called when matchs `/users` path
router.get('/users', function(req, res, next) {
    res.send('respond with a resource');
 });
