example doesn't work

const koa = require('koa');
const websockify = require('koa-websocket');
const router = require('koa-router');
const app = new koa();
const api = router();
const socket = websockify(app);

api.get('/*', function* (next) {
    this.websocket.send('Hello World');
    this.websocket.on('message', function(message) {
        console.log(message);
    });
});

app.ws.use(api.routes()).use(api.allowedMethods());
app.listen(3000);

When I try to debug with wscat -c ws://localhost:3000 nothing happens 😦

[kudos]

koa-router is not explicitly supported, but patches with tests are welcome.
