Async Function Support

Vibeflow provides full support for async functions, allowing you to use the @vibe decorator in modern asynchronous Python applications, including with web frameworks like FastAPI.

Standalone Async Functions

You can decorate async functions in the same way you decorate synchronous ones. Vibeflow will detect the async def signature and generate an awaitable coroutine.

Example: async_functions.py

Here is a basic example of a standalone async function managed by Vibeflow.

import asyncio
from vibeflow import vibe

@vibe
async def add(a: int, b: int) -> int:
    """Add two numbers together and return the result."""
    pass

async def main():
    """Main function to run the async function add."""
    print("Adding 25 and 17...")
    result = await add(25, 17)
    print(f"Result of add(25, 17) is: {result}")

if __name__ == "__main__":
    # This allows the async function to be run from the command line.
    asyncio.run(main())

To run this, you simply execute the script, and asyncio.run() handles the event loop.
