trying server.close() but that doesn’t seem to do it

Did you try

server.express.stop()

That might do it

yeah

It looks like you need an reference of

app.listen()

to run

.close()

, but it looks like Yoga swallows that instance

hmnmmm

Here we go. https://github.com/graphcool/graphql-yoga/issues/100

server.start() returns a promise, so you can await that
