Nest is a platform agnostic framework, means u can reuse the logical part across different platform based on the need of application
Controller are responsible for handling incoming request and return response to the client. Basically controller works as request handler and provides routing mechanism and responsible to provide suitable response for the request.
Controller uses classes and decorator, decorator to provide metadata and enable nest to create routing map. @Controller decorator to specify its a controller , you can provide metadata inside the decorator like route path prefix, path prefix helps to group and provide nesting routing.
@Get decorator in controller is same as the HTTP Get request method, you can pass route name in the decorator, nest will internally map it as the nesting routing
Nest employs two different method options for manipulating responses
- Standard :-
Uses built in method , when request handler returns an object the nest will automatically serialize it into json and when returns and string it will send it directly without attempting to serialize it, which makes response handling simple. To uses various status code use @HttpCode , else it will provide response code always 200 most of the time except in the post request. - Library Specific :- If you want to use the native response method by that library like Express.
Note:- Both Approaches not work at the same time.
