Dinoloop has been designed from the start for gradual adoption, and you can use as little or as much dinoloop as you need. Perhaps you only want to develop some "REST APIs" using dinoloop and other REST APIs can be developed using expressjs. In this section, we will show how to create dinoloop REST API to an existing express app.

Step 1: Add HomeController (file: home.controller.ts)
import { ApiController, Controller, HttpGet } from 'dinoloop';

@Controller('/home')
export class HomeController extends ApiController {

@HttpGet('/get')
get(): string {
    return 'Hello World!';
}

}
Step 2: Mount dinoloop and bind to express instance (file: app.ts)
const app = express();
app.use(bodyParser.json());

// Dino requires express instance and base-uri to which dino will be mounted
const dino = new Dino(app, '/api');

// Dino requires express router too
dino.useRouter(() => express.Router());

// Register controller
dino.registerController(HomeController);

// Bind dino to express
dino.bind();

// These are your normal express endpoints
app.get('/home', (req, res, next) => {
res.status(200).json('Hello World!');
});

app.get('/about', (req, res, next) => {
res.status(200).json('Hello World!');
});

// Start your express app
app.listen(8088, () => console.log('Server started on port 8088'));
Dinoloop is mounted on /api and all of its controller routes/endpoints which are registered with dinoloop are also mounted on /api. Dinoloop will handle those requests which are mounted on /api i.e. /api/home/get, the other end points /home and /about which are created by expressjs are not handled by dinoloop, this way you can slowly migrate your existing express app to dinoloop or you can start writing your new REST APIs using dinoloop.
