Both httpContext and injector are set by tachijs. To check they are set, we have to see one of them is defined like this.httpContext != null or this.injector != null.

To make it simple, I'm going to put everything in one property this.context.

So it will be like the below.

interface Context {
  req: express.Request
  res: express.Response
  inject: (key: string) => any
}

class BaseController {
  context?: Context
}

This will be implemented next version and old legacy props, inject, injector and httpContext are deprecated from v1.
