# Controller

## Concepts

* It is part of the Mandarine MVC module.
* It is responsible for the creation of endpoints & handling HTTP requests.
* It accepts the use of DI, however, this type of component is not injectable.

## Usage

```typescript
@Controller(baseRoute?: string)
```

* baseRoute
  * Optional.
  * Default: Null
  * Base route for all endpoints listed inside controller.

import { Controller } from "https://deno.land/x/mandarinets/mod.ts";

@Controller()
export class MyController {
}
```

Example II

```typescript
import { Controller } from "https://deno.land/x/mandarinets/mod.ts";

export class MyController {
}
```
