serverless-graphql VS subscriptions-transport-ws

Since then, the ecosystem has changed. Using the Serverless Framework makes deployment simpler. We released the managed Tracetest App making any serverless-based systems simpler to instrument and test. You can now test public-facing apps with no infra overhead!

We see some great results from using these in conjunction with frameworks such as SST or Serverless, and also some real spaghetti from people who organically proliferate 100’s of functions over time and lose track of how they relate to each other or how to update them safely across time and service. Buyer beware!

When we think about AWS serverless service, the first thing that comes to our mind is Lambda function. Yes, the quickest way to deploy this backend Express JS app to AWS is to deploy it as a Lambda function. The easiest way is using Serverless Framework.

In this example, we're using the serverless framework to quickly set up the Lambda function along with an API gateway for the entry point. The lambda function is a simple Koa REST API with a few functional endpoints.

Naturally, there are several options available to declare your cloud resources. The options with the most popularity are the CDK, AWS CloudFormation, SST, Serverless framework, Terraform, and AWS SAM. There are others, but when talking about Infrastructure as Code (IaC), these are the ones you hear about most often.

It's a bit easier in Python if you use tools like https://www.serverless.com/. I'm not sure if Rust has something similar yet.

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).

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.

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.

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.

The javascript implementation is at subscriptions-transport-ws

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.

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.

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.

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!)
