--  human-readable json configuration
-- nested routes (*i.e. `/user/:id:` vs. `/user/post/​:id:​`*)
-- useful http methods: GET, POST, PUT, DELETE
-- manage URL, query and body arguments:
-  - multipart/form-data
-  - application/x-www-form-urlencoded
-  - application/json
-- required vs. optional parameters with a default value
-- parameter renaming
-- generic authentication system (*i.e. you can override the built-in*)

+- [x] human-readable json configuration
+- [x] nested routes (*i.e. `/user/:id:` and `/user/post/​:id:​`*)
+- [ ] nested URL arguments (*i.e. `/user/:id:` and `/user/:id:/post/​:id:​`*)
+- [x] useful http methods: GET, POST, PUT, DELETE
+- [x] manage URL, query and body arguments:
+  - [x] multipart/form-data (variables and file uploads)
+  - [x] application/x-www-form-urlencoded
+  - [x] application/json
+- [x] required vs. optional parameters with a default value
+- [x] parameter renaming
+- [ ] generic authentication system (*i.e. you can override the built-in one*)
+- [x] generic type check (*i.e. implement custom types alongside built-in ones*)
+- [ ] built-in types
+	- [x] `any` - wildcard matching all values
+	- [x] `int` - any number (*e.g. float, int, uint*)
+	- [x] `string` - any text
+	- [x] `varchar(min, max)` - any string with a length between `min` and `max`
+	- [ ] `<a>` - array containing **only** elements matching `a` type
+	- [ ] `<a:b>` - map containing **only** keys of type `a` and values of type `b` (*a or b can be ommited*)
+- [ ] generic controllers implementation (shared objects)
+- [ ] response interface
