Documenation
@Router(baseUrl?: string)
Used to create a router out of a class, this binds several properties along with a method for binding to express.
Router.enable(app: Express | Router)
Method on routers used to bind to express, I'd advise using bind()
instead as it removes any type errors.
@Route(path?: string, method?: Method)
Turns a method into a route, if a path is not specified then this becomes the equivalent of app.use()
. The method can be any supported method listed on the expressjs documentation.
@Type(contentType: string)
If you plan on return
ing values from your method, use this to specify the content type.
@Param(parameter: string, required?: boolean, description?: string)
Reads a parameter from the request and adds it to your method's arguments. By default it will be required and will throw an error if not present. The description serves as a way to describe your code easily.
@Body(key: string, required?: boolean, description?: string)
Reads a value in body from the request and adds it to your method's arguments. By default it will be required and will throw an error if not present. The description serves as a way to describe your code easily.
@Query(key: string, required?: boolean, description?: string)
Reads a value in the query parameters from the request and adds it to your method's arguments. By default it will be required and will throw an error if not present. The description serves as a way to describe your code easily.
