import App from 'douh';

const app = new App();

app.use(() => {
  return 'hello world!';
});

app.listen(3000);

Middleware

douh supports async middleware.

app.use(async (req, res, next) => {
  console.time('start');
  await next();
  console.timeEnd('end');
});

Use Router

import App, { Router } from 'douh';

const app = new App();
const router = new Router();

router.get('/ping', (req, res, next) => {
  return 'pong';
});

app.use(router.middleware());

app.listen(3000);

bodyParser

you can use bodyParser middleware.

import App, { bodyParser, Router } from 'douh';

const app = new App();
const router = new Router();

router.post('/ping', (req, res, next) => {
  console.log(req.body);
  console.log(req.files); // when content type is multipart/form-data
  return 'pong';
});

app.use(bodyParser);
app.use(router.middleware());

app.listen(3000);

Use Service

you can use service with @Service decorator. access service with req.service.

import App, { Service } from 'douh';

@Service()
class DouhService {
  public hello(name: string) {
    return `hello ${name}`;
  }
}

const app = new App();
app.use(async (req, res) => {
  const result = req.service.userService.hello('douh');
  return result; // hello douh
});

Use Repository

you can use repository with @Repository decorator. access repository in service constructor.

@Repository()
class DouhRepository {
  hello(name) {
    return `hello ${name}`;
  }
}

@Service()
class DouhService {
  constructor(private readonly douhRepository: DouhRepository) {}

  hello(name: string) {
    return this.douhRepository.hello(name);
  }
}

const app = new App();
app.use(async (req, res) => {
  const result = req.service.douhService.hello('douh');
  return result; // hello douh
});

Use File Service

you can use file service with middleware.

import App, { serveStatic } from 'douh';

const app = new App();

app.use(serveStatic('public')); // it must be placed before bodyParser
app.use(bodyParser);

app.listen(3000);
