aah framework supports domain and subdomains seamlessly and reverse route lookup by route name effectively.
aah framework uses routing algorithm implementation from httprouter developed by @julienschmidt. Customized by author of aah framework @jeevatkm. Router supports path variables in the routing pattern and matches against the request method and scales better.
The router is optimized for high performance and a small memory footprint. It scales well even with very long paths and a large number of routes. A compressing dynamic trie (radix tree) structure is used for efficient matching.
Router config is very flexible in nature with default values for effective usage.

- Domain, sub-domains and wildcard sub-domains supported seamlessly.
- Static Files - Serve static file or directory via
- Directory Listing - Directory listing is supported, presented clean and nicely.
- Custom NotFound - Register your custom controller
not foundaction to handle this behavior.
- Only explicit matches - By design of this router, a request can only match exactly one or no route. As a result, there are also no unintended matches, which makes it great for SEO and improves the user experience.
- Stop caring about trailing slashes - Choose the URL style you like, the router automatically redirects the client if a trailing slash is missing or if there is one extra. Of course it only does so, if the new path has a handler. If you don’t like it, you can turn off this behavior
redirect_trailing_slash = falsein the routes config.
- Path auto-correction - Besides detecting the missing or additional trailing slash at no extra cost, the router can also fix wrong cases and remove superfluous path elements (like
//). Is CAPTAIN CAPS LOCK one of your users? HttpRouter can help him by making a case-insensitive look-up and redirecting him to the correct URL.
- Parameters in your routing pattern - Stop parsing the requested URL path, just give the path segment a name and the router delivers the dynamic value to you. Because of the design of the router, path parameters are very cheap.
- Zero Garbage - The matching and dispatching process generates zero bytes of garbage. In fact, the only heap allocations that are made, is by building the slice of the key-value pairs for path parameters. If the request path contains no parameters, not a single heap allocation is necessary.
- No server crashes - aah framework gracefully logs error information and display the message.
- Perfect for APIs - The router design encourages to build sensible, hierarchical RESTful APIs. Router has builtin native support for OPTIONS requests and
