Subscriptions-transport-ws: Pass in a koa server?

[myyellowshoe]

From the docs I can see the subscriptionServer takes the standard node http node server.
I'd like to use a koa 2 server instead. Is that possible?

@myyellowshoe I don't actually know. Maybe you can try it and let us know? 🙂

I'm not too familiar with koa but you might be able to do something like this to get the node http server:

const app = require('koa')();
const http = require('http');
app.use(...);
var server = http.createServer(app.callback());
server.listen(8080);

and pass http into the subscriptionServer.

It would be great to add this setup to the documentation. Hapi uses a similar pattern.

With koa2, this works fine :

const app = new Koa();
app.use(...);

const server = app.listen(8080);

new SubscriptionServer({
  subscriptionManager,
  ...
}, {
  path: '/subscriptions',
  server,
});

Note the heading / in the path. Could not get it to work without it.

Cool I'll have to try it out. If I get it to work. Happy to help get this into the docs.

Should work now (since we allow any server to pass to WebSocket.Server instance).

@Urigo Great to know. @kouak Worked like a charm.
