API

Router Options

You can pass a route to handle not found routes.

const router = new Router({
  onNotFound: (request, response) => {
    response.statusCode = 404;
    response.end('Route not found :(');
  },
});

To enforces url patterns in routes, the path pattern is for normal paths and param is for parameters name, you can pass: camelCase, PascalCase, snake_case, kebab-case, any.

const router = new Router({
  patterns: {
    path: 'camelCase',
    param: 'camelCase',
  },
});

Register routes

To register new routes, supports all HTTP methods: GET, POST, PUT, PATCH, DELETE, HEAD, TRACE, CONNECT, OPTIONS.

router.on('GET', '/', (request, response) => response.end('Hello World'));

Also has the syntax sugar:

router.get('/', (request, response) => /* Your code */);

router.post('/', (request, response) => /* Your code */);

router.put('/', (request, response) => /* Your code */);

router.patch('/', (request, response) => /* Your code */);

router.delete('/', (request, response) => /* Your code */);

router.head('/', (request, response) => /* Your code */);

router.trace('/', (request, response) => /* Your code */);

router.connection('/', (request, response) => /* Your code */);

router.options('/', (request, response) => /* Your code */);

Parametric

router.get('/user/:id', (request, response, params) => {
  const { id } = params;
  response.end(`You id is: ${id}`);
});

Wildcard

router.get('/user/*', (request, response, params) => {
  const wildcard = params['*'];
  response.end(`The wildcard passed: ${wildcard}`);
});

Multiple routers

To use multiple routers you can merge them

const router = new Router();
router.get('/', (request, response) => response.end('Hello World'));

const userRouter = new Router();
userRouter.get('/', (request, response) => response.end('Hello World / user'));

router.merge(userRouter, '/user');
