How do I use a wildcard in JWT unless?

I'm using express-jwt to secure my node application, and am wondering how I can use a wildcard in the unless parameter. My working code is below, what I'd really like to do is open up access to anything that has a path starting with '/login' so I don't have to list every single resource. When I add '/login*' to the unprotected array it ends up blocking /login with a 401/unauthorized.

Works:

// routes open to all
var unprotected = [
'/login',
'/login/app/main.js',
'favicon.ico'
];

// configure jwt
var jwtCheck = jwt({
secret: new Buffer(config.get('auth0.secret'), 'base64'),
audience: config.get('auth0.clientid')
});

// insert jwt middleware
app.use( jwtCheck.unless({path: unprotected}) );


Doesn't work:

// routes open to all
var unprotected = [
'/login*',
'favicon.ico'
];

// configure jwt
var jwtCheck = jwt({
secret: new Buffer(config.get('auth0.secret'), 'base64'),
audience: config.get('auth0.clientid')
});

// insert jwt middleware
app.use( jwtCheck.unless({path: unprotected}) );

Answer

The regexp needs to exist outside the quotes:

var unprotected = [
  /\/login*/,
  /favicon.ico/
];

Note that at this time with express-unless you can't mix regexp and strings in the same config array, which is why the second argument needs to have forward slashes instead of quotes.
