three ways to deploy a serverless graphQL API
graphql-yoga is built on other packages that provide functionality required for building a GraphQL server such as web server frameworks like express and apollo-server, GraphQL subscriptions with graphql-subscriptions and subscriptions-transport-ws, GraphQL engine & schema helpers including graphql.js and graphql-tools, and an interactive GraphQL IDE with graphql-playground.

Subscriptions and Live Queries - Real Time with GraphQL
The most common used (but not best maintained) library for such a PubSub engine in the GraphQL context is graphql-subscriptions. There are also adapters available for more distributed systems (where all GraphQL API replicas must be notified about the event) e.g. over Redis.
-
GraphQL over WebSockets
During that work, we created and merged the reference implementation into graphql-js and created two supporting libraries: graphql-subscriptions and subscriptions-transport-ws. Here is a talk with deep dive into all the details.

Using useSWR as an alternative to Subscriptions?
The Prisma / GraphQL-Yoga comes with Subscriptions, and this was the first thing I came across when my client asked for realtime updates. The implementation was quite difficult - took me a long time. Eventually, it was working locally, and in staging. However, when it came to the production environment, for some reason it just didn't work! This unfortunately ended up with a user losing an auction, which ultimately went to court etc.

GraphQL subscriptions not working consistently
There are also other solutions available: https://github.com/apollographql/graphql-subscriptions#pubsub-implementations

Build a chat app with GraphQL Subscriptions & TypeScript: Part 2
First, let's try to understand what PubSub is exactly. Apollo Server uses a publish-subscribe (pub/sub) model to track events that update subscriptions. The graphql-subscriptions library included in all apollo-server packages (including middleware integrations) provides a PubSub class as a basic in-memory event bus.

GraphQL the Simple Way, or: Don't Use Apollo
To add this, I can just expand the basic setup above. To do so, I do actually use a couple of small Apollo modules! Most can be picked and configured independently. For this case, graphql-subscriptions provides a little bit of pubsub logic that works within resolvers, and subscriptions-transport-ws integrates that into Express to handle the websockets themselves. Super helpful

Fixing a 3 second lockup in our app by switching from Apollo Client to URQL
Additionally, we created a bit more work for ourselves by upgrading the library we use for GraphQL subscriptions over web sockets, moving from the seemingly unmaintained subscriptions-transport-ws to the active graphql-ws project (which is URLQ’s library of choice for subscriptions).
- Is this a graphql thing or JSON thing?

GraphQL Subscriptions and Mikro-Orm in 2021
Okay but seriously, if you've fallen down the rabbit hole of Apollo docs pointing you towards one library (subscription-transport-ws) which then points you to another (graphql-ws) , and so on and so forth, then hopefully this helps pull you out.

Looking for GraphQL server with ws-transport ability
I'm looking for graphql server that can do queries and mutations over websocket, like subscriptions-transport-ws. Juniper and async-graphql both looks promising and async-graphql at least uses wording Subscriptions (WebSocket transport) in features but i couldn't find much more or any examples about that from the docs or repo.

How does a client know if the server managing its subscription goes offline? (Multiple instances)
The javascript implementation is at subscriptions-transport-ws

GraphQL over WebSockets
Okay, so, how do I use WebSockets to add support for the GraphQL subscription operation? Doing a basic Google search, you’d be faced with a single solution, namely subscriptions-transport-ws. Looking through the repository, checking recent comments, reading through the issues and open PRs - might have you notice the abundance of bugs and their security implications. A summary can be found here.

The Stack #3
While subscription-transport-ws from Apollo initially started off this journey, it is not actively maintained and GraphQL WS by Denis definitely is a great replacement to that having no external dependencies and having the ability to work across many frameworks.
-
I need a little help implementing user online status tracking with Apollo/GraphQL.
apollo-server plans to remove WebSocket support, which is currenlty done over the deprecated graphql-ws protocol (as implemented by the unmaintained subscription-transport-ws module by apollo), in the next major version.
-
GraphQL Query and Mutation over Websockets
https://github.com/apollographql/subscriptions-transport-ws, which is used by Apollo Server does support executing queries and mutations actually but you are better off moving away it anyway (check the text in their README!)
