Execution Context

Whenever Intent receives a request, it encapsulates the Request, Response, Controller, Route Handler and Reflector class into a single class. The main aim of this is to provide a standardisation across all type of applications and protocols. Whenever you use Guards or Custom Route Param Decorators, you will come across Execution Context.

Http Context

To access the Request, Response of the current HTTP Context, you can call the switchToHttp method inside the execution context object.

const httpCtx = ctx.switchToHttp(); // returns an instance of HttpExecutionContext

const req = ctx.getRequest(); // returns the HTTP Request Object
const res = ctx.getResponse(); // returns the HTTP Response Object

Using the same Execution Context, you could also get the type of the Controller class the Controller#method type.

const cls = ctx.getClass();

const method = ctx.getHandler();

Fruther, if you would like to read some data from these methods, you can also get the instance of the Reflector class from the execution context and use it like below.

const reflector = ctx.getReflector();

const roles = reflector.getFromMethod('roles');
