AsyncAPI Conference 2021

Learn what are the steps to become a member of AsyncAPI Technical Steering Committee (TSC). How to start contributing, how to become a committer (maintainer) and what it actually means for you to be a TSC member.

AsyncAPI is an open-source project that seeks to promote and facilitate the development of asynchronous APIs and event-driven architecture (EDA). The goal of AsyncAPI is to make building EDAs as simple as building REST APIs. In this talk, I'll explain our project, the contribution guide, the Diátaxis method for classifying technical content, and how to contribute to our Dev Docs.

In this talk, Fran will speak about the current state of the AsyncAPI Initiative and the future vision and plans. Join him to discover more about the project, the people behind it, and how to join them.

I'm working at Adeo, the European leader for DIY retail, on a strategic digital product. Our task is to optimize the company's articles store prices. To do so, our product performs end-to-end calculation throughout the value chain. We use a Kafka-based architecture to handle the calculation requests and send back the results. Our requesters are partners from the headquarters. An expansion to the company's business units is planned for 2022. But how to efficiently communicate with our partners and ensure that their asynchronous requests exactly match our expected messages structure? How to provide our partners with an easy-to-use and user-friendly exchange framework? How to help them produce their requests and consume our results easily? AsyncAPI is a part of the solution! We use this amazing specification to provide a live documentation, always up to date, based on our Kafka AVRO records. This talk is about a real value chain use case with a technical implementation, that provide our partners with exciting reader experience in production. Come and discover this use case and how to deal with AsyncAPI and AVRO files in a digital product based on Maven and Spring Boot technologies.

Socket.IO has evolved from a JavaScript library for realtime web applications to a language agnostic protocol enabling duplex, event-driven communication. In spite of its maturity and wide adoption across the industry, the Socket.IO ecosystem is still lacking support for documenting APIs in a standardised manner. The rise of the AsyncAPI specification presents itself as a great opportunity to finally tackle this problem. In this talk, Dimitrios is going to showcase how the Socket.IO protocol can be modelled through AsyncAPI, followed by a step-by-step tutorial involving the creation of a specification YAML file, given an existing Socket.IO API. The final part of this talk will be dedicated to Asynction, a Socket.IO micro-framework written in Python, that is entirely driven by the AsyncAPI specification. Even though this presentation focuses on Socket.IO, it serves as an example of how one could express any event-driven protocol using AsyncAPI.

The AsyncAPI specification allows you to define your Event-Driven apps. The Spring Cloud Stream framework allows you to implement Event-Driven microservices. In this talk, we will bring the two together and show how developers can go from Design to Code using AsyncAPI documents and the AsyncAPI generator that can generate code using Spring Cloud Stream Binders. At runtime, the Binders enable connection to external middleware like RabbitMQ, Kafka, Solace PubSub+ to name a few. This talk will include a hands-on demo using Java, Spring Cloud Stream, and the AsyncAPI java-spring-cloud-stream-template.

You've built your Kafka applications and now you're reaping the benefits of stream processing. You realise you're sitting on a gold mine of data that others use to enrich their applications. But how can you make others aware and help enable them to join in your successes? This talk will describe how we have adopted AsyncAPI as the mechanism to socialise Kafka event streams within an organisation. AsyncAPI provides the means to document a data source as an external API - but Kafka provides some unique challenges when using the document to write an application. Schema registries have vendor specific serialisation libraries. Kafka's distributed topology doesn't always map to the specification. We will explore the scope of the current specification and discuss new requirements for the Kafka use case to enhance the developer experience.

The rise of Event Driven Architecture is a necessary evolutionary step towards cloud-native applications but events come also with challenges! One of the first you are facing when starting up as a development team - aside the technology choice - is how to describe these events structure? And then: how can we efficiently work as a team and improve collaboration to reduce the development life cycle and TTM (Time To market)? New standards like CloudEvents or AsyncAPI came up to address these needs allowing structure description. But, people often ask: Should I use CloudEvents or AsyncAPI? There is the belief that CloudEvents and AsyncAPI are competing on the same scope. I see things differently, and I’d like to explain why you may need both of them without increasing the level of complexity from the development perspective! I’ll also introduce Microcks: a tool to easily simulate and test CloudEvents and AsyncAPI combinations in minutes. In this session, we will: - Go over the introduction of both specifications, - Highlight their strengths and complementarity, - Give an overview of Microcks for mocking and testing “CloudEvent-ified AsyncAPIs” ;-)

CNCF Serverless Workflow is a vendor-neutral and open-source workflow ecosystem. The project hosts the core specification defining a domain-specific workflow language, as well as a set of developer tools and runtimes supporting the specification. Serverless Workflow is standards-based and provides support for AsyncApi which plays a big role in defining message-driven orchestrations of third-party microservices. In this talk we will give an introduction to the Serverless Workflow project. We will also describe and demo how AsyncApi is integrated with the spec and showcase how AsyncApi plays a big role and solves important problems in workflow orchestrations.
