How can I hook into fast refresh?

[remihuigen]

I've extended the express server with a second Apollo server on /api/public/graphql. Reason is that i wanna serve different schemas for public and private api. The public schema is a filtered version of the private schema.

In the /api/public/grapghql route i'm creating this server as follows

// Code for creating serverConfig

const apolloServer = new ApolloServer({ ...serverConfig })

await server.start()

export default (commonContext: any) => {
    router.use('/', json(graphql?.bodyParser), expressMiddleware(apolloServer, {
        context: async ({req, res}) => {
            const context = await commonContext.withRequest(req, res)
            return context
        }
    }));
    return router
}

This all works fine, except that a new server is created each time Keystone is refreshed, without closing the old server.

So i wanna be able to hook into that and run server.stop()

Any suggestions on how to do that?

Cheers!
