Usage

Defining a Step

from motia import FlowContext, queue

config = {
    "name": "process-data",
    "triggers": [queue("data.created")],
    "enqueues": ["data.processed"],
}

async def handler(data: dict, ctx: FlowContext) -> None:
    ctx.logger.info("Processing data", data)
    await ctx.enqueue({"topic": "data.processed", "data": data})

API Steps

from motia import ApiRequest, ApiResponse, FlowContext, http

config = {
    "name": "create-item",
    "triggers": [http("POST", "/items")],
    "emits": ["item.created"],
}

async def handler(req: ApiRequest, ctx: FlowContext) -> ApiResponse:
    ctx.logger.info("Creating item", req.body)
    await ctx.enqueue({"topic": "item.created", "data": req.body})
    return ApiResponse(status=201, body={"id": "123"})

Streams

from motia import Stream

# Define a stream
todo_stream = Stream[dict]("todos")

# Use the stream
item = await todo_stream.get("group-1", "item-1")
await todo_stream.set("group-1", "item-1", {"title": "Buy milk"})
await todo_stream.delete("group-1", "item-1")
items = await todo_stream.get_group("group-1")

Testing

Running Integration Tests

Integration tests require a running III Engine instance. Make sure to have it built or installed before running tests.

Install dev dependencies:
```
cd motia && uv sync --all-extras
```
Run tests:
```
uv run pytest
```

Test Configuration

Tests use non-default ports to avoid conflicts:

Engine WebSocket: ws://localhost:49199
HTTP API: http://localhost:3199

Set III_ENGINE_PATH environment variable to point to the III engine binary.

Test Coverage

The integration test suite covers:

Bridge connection and function registration
API triggers (HTTP endpoints)
KV Server operations
PubSub messaging
Logging module
Motia framework integration
Stream operations (when available)
State management (when available)
