spec VS serverless-websockets

AsyncAPI: Interested in how to define your WebSocket APIs? One of the most advanced realtime specifications is the AsyncAPI specification, which comes with various generators for code and documentation, as well as renderers for the specifications.

Our journey with FastStream started when we needed to integrate our machine learning models into a customer's Apache Kafka environment. To streamline this process, we created FastKafka using AIOKafka, AsyncAPI, and asyncio. It was our first step in making message queue management easier.

Automatic Docs: Stay ahead with automatic AsyncAPI documentation

FastStream supports in-memory testing, AsyncAPI schema generation and more... If you are interested, please support our project by giving a GH start and joining our discord server.

However, in order for the system to work effectively, there must be a common understanding between the components regarding events and their data structures. This is where AsyncAPI comes in; it helps define a contract that describes how the components communicate and behave effectively.

You can also take a look at https://www.asyncapi.com/ (a spec for asynchronous APIs). It's useful for this use case, that is, building a well structured websocket interface with pub/sub.

Sure! Next step I am working on AsyncAPI scheme generation by your application code. It's also includes a project generation from scheme, scheme web view (lika the Swagger for OpanAPI), etc. It will a much difficult than just another broker implementation...

Onboarding - Enable developers to quickly learn how to consume the exposed APIs. For example, offer OpenAPI or AsyncAPI documentation and provide a portal and sandbox.

For long running jobs, it is useful to inform the user that something is going on. Nobody likes sitting and waiting hoping that work is being done. To help with this, we provide push notifications via the WebSocket microservice we created in my WebSocket tutorial.

For a real world example, you can check out my repo on AWS WebSockets.

There are two things you must do before configuring a custom domain: purchase your domain name and setup a public hosted zone. These will need to be done manually in order to pick up and deploy the stack contained in part five of the GitHub repo for the WebSocket.

Just like the three previous parts, the work is done ahead of time. To deploy the updates that add user notifications, run the following command in a terminal in the root of the repo on your local machine.

To get started with the spec for our WebSocket, checkout the part-three branch in the serverless-websockets repo in GitHub with the following command:

If you followed part one of this series, you deployed a basic WebSocket into your AWS account. It has the ability to add and remove connections, as well as add and remove subscriptions to specific entities. Today we are going to use a branch in that repo that enhances what we had.

Today we're going to go through an example of a WebSocket written in a SAM template. I chose a SAM template because of how easy it is to deploy a serverless application directly into AWS without the need for 3rd party services.
