Easily generate type-safe and async Python applications from AsyncAPI 3 specifications.

Features

• Creates Application class from AsyncAPI 3 specifications, implementing every operation in the file
• Generates typed Python code (messages are generated using datamodel-code-generator)
• Performs dynamic validation of messages with Pydantic 2
• Enforces the user code to implement all consumer methods as described by spec
• Provides async code
• Spec parser references other files through absolute or relative paths
• Spec parser references other files through url
• Supports request-reply pattern
• Supports publish-subscribe pattern
• AsyncAPI trait support
• Customizable message encoder/decoder

Requirements

• python>=3.10
• pydantic>=2
• pytz
• For codegen extra
  • jinja2
  • typer
  • datamodel-code-generator
  • pyyaml
• For amqp extra
  • aio-pika

Installation

For code generation (development env), run:

pip install asyncapi-python[codegen]

For runtime, run:

pip install asyncapi-python[amqp]

You can replace amqp with any other supported protocols. For more info, see Supported Protocols section.

Supported Protocols / Use Cases

Below, you may see the table of protocols and the supported use cases. The tick signs (✅) contain links to the examples for each implemented protocol-use case pair, while the hammer signs (🔨) contain links to the Issues tracking the progress for protocol-use case pairs. The list of protocols and use cases is expected to increase over the progress of development.

Use Case	AMQP
Pub-Sub	✅ amqp-pub-sub
Work Queue	✅ amqp-work-queue
RPC	✅ amqp-rpc

Documentation

Although there's no documentation available at the moment, a set of comprehensive examples with comments for each implemented use-case is under the examples directory.
