framework4 subdomains

Hello, how to dynamically link to different subdomains, I can't find any way to achieve it

We disabled subdomain routing because it was useless and not used in 99.99% of cases. Every request contains a hostname, so depending on the hostname, you can archive a subdomain name (but you can't affect routing). What do you need it for, in particular?

How can I dynamically determine subdomains and then route to different routes? I change the URL in the middleware, but it does not route to the corresponding router.

I need different subdomains to link to different routes, but it seems this can't be achieved in Total4？

Hmm. I'm looking at the source code, and maybe it works with subdomain routing. I'm not sure if this works.

// Route with flags
ROUTE('[eshop,store]/', action);
// e.g. http://eshop.totaljs.com/
// e.g. http://store.totaljs.com/

ROUTE('[*]/', action);
// All subdomains

ROUTE('[nice*]/', action);
// All subdomains which contain `nice` word

We removed this functionality in Total.js v5. If the above solution will not work, then you can try something like this:

ON('request', function(req) {
    // This property is used for routing:
    // req.uri.pathname = '/home/';
});

I'll give it a try, thank you very much.

I also looked at the source code. This only exists in the v3 version. It seems that v4 does not support such usage.

Although it lacks documentation, we implemented it for backward compatibility with Total.js v3. I hope it works: https://github.com/totaljs/framework4/blob/master/index.js#L3925

ROUTE('GET /', function(){this.json('index')});
ROUTE('GET [admin]/', function(){this.json('admin')});
ROUTE('GET [foliko]/', function(){this.json('foliko')});

I tried this method, but it doesn't seem to work. I really can't find a solution, so I have no choice but to split the service into two and control it with nginx.

I'll test it today and I'll try to fix it.

I have looked at it and it's not implemented in the routing mechanism. I have checked possible implementation and it's really complicated. Maybe you can try something like this:

exports.install = function() {
    
    ROUTE('GET /', subdomain({
        admin: funtion() {
            this.json('admin');
        },
        foliko: funtion() {
            this.json('foliko');
        }
    }));

};

function subdomain(map) {
    return function() {
        var self = this;
        var subdomain = self.subdomain ? self.subdomain.join('.') : null;

        if (subdomain) {
            for (var key in map) {
                if (subdomain === key) {
                    map[key].apply(self, arguments);
                    return;
                }
            }
        }

        self.invalid(404);
    };
}

The controller.subdomain property returns a parsed subdomain. Therefore, you can use this property in the controller's action to determine the subdomain name.

Okay, thank you very much, I'll give it a try
