asyncdatapackage 0.1.5

Asynchronous datapackage serializer and transport layer

AsyncDataPackage

AsyncDataPackage is a lightweight asyncio-based framing layer that converts arbitrary byte streams into structured Python dictionaries.

It is transport agnostic and can operate on:

• TCP
• SSH
• WebSockets
• Bluetooth
• Serial Ports
• UDP
• Custom transports

The transport only needs to provide:

await send(bytes)
await receive(...)

---

Installation

pip install asyncdatapackage

---

Quick Example

from asyncdatapackage import AsyncDataPackage

datapackage = AsyncDataPackage(
    write_function=my_send,
    read_function=my_receive
)

await datapackage.start()

Send:

await datapackage.send_datapackage(
    {
        "type": "DATA",
        "message": "hello"
    }
)

Receive:

packet = await datapackage.receive_datapackage()

Result:

{
    "type": "DATA",
    "message": "hello"
}
