- You want to leverage IDE features like auto-completion and type checking for better developer experience.
|
||||
|
||||
By providing both unstructured and structured state management options, CrewAI Flows empowers developers to build AI workflows that are both flexible and robust, catering to a wide range of application requirements.
|
||||
|
||||
## Flow Control
|
||||
|
||||
### Conditional Logic
|
||||
|
||||
#### or
|
||||
|
||||
The `or_` function in Flows allows you to listen to multiple methods and trigger the listener method when any of the specified methods emit an output.
|
||||
|
||||
```python
|
||||
import asyncio
|
||||
from crewai.flow.flow import Flow, listen, or_, start
|
||||
|
||||
class OrExampleFlow(Flow):
|
||||
|
||||
@start()
|
||||
def start_method(self):
|
||||
return "Hello from the start method"
|
||||
|
||||
@listen(start_method)
|
||||
def second_method(self):
|
||||
return "Hello from the second method"
|
||||
|
||||
@listen(or_(start_method, second_method))
|
||||
def logger(self, result):
|
||||
print(f"Logger: {result}")
|
||||
|
||||
|
||||
async def main():
|
||||
flow = OrExampleFlow()
|
||||
await flow.kickoff()
|
||||
|
||||
|
||||
asyncio.run(main())
|
||||
```
|
||||
|
||||
When you run this Flow, the `logger` method will be triggered by the output of either the `start_method` or the `second_method`. The `or_` function is to listen to multiple methods and trigger the listener method when any of the specified methods emit an output.
|
||||
|
||||
The output of the Flow will be:
|
||||
|
||||
```
|
||||
Logger: Hello from the start method
|
||||
Logger: Hello from the second method
|
||||
```
|
||||
|
||||
#### and
|
||||
|
||||
The `and_` function in Flows allows you to listen to multiple methods and trigger the listener method only when all the specified methods emit an output.
|
||||
|
||||
```python
|
||||
import asyncio
|
||||
from crewai.flow.flow import Flow, and_, listen, start
|
||||
|
||||
class AndExampleFlow(Flow):
|
||||
|
||||
@start()
|
||||
def start_method(self):
|
||||
self.state["greeting"] = "Hello from the start method"
|
||||
|
||||
@listen(start_method)
|
||||
def second_method(self):
|
||||
self.state["joke"] = "What do computers eat? Microchips."
|
||||
|
||||
@listen(and_(start_method, second_method))
|
||||
def logger(self):
|
||||
print("---- Logger ----")
|
||||
print(self.state)
|
||||
|
||||
|
||||
async def main():
|
||||
flow = AndExampleFlow()
|
||||
await flow.kickoff()
|
||||
|
||||
|
||||
asyncio.run(main())
|
||||
```
|
||||
|
||||
When you run this Flow, the `logger` method will be triggered only when both the `start_method` and the `second_method` emit an output. The `and_` function is used to listen to multiple methods and trigger the listener method only when all the specified methods emit an output.
|
||||
|
||||
The output of the Flow will be:
|
||||
|
||||
```
|
||||
---- Logger ----
|
||||
{'greeting': 'Hello from the start method', 'joke': 'What do computers eat? Microchips.'}
|
||||
```
|
||||
|
||||
### Router
|
||||
|
||||
## Adding Crews to Flows
|
||||
|
||||
- The easiest way to create flows with Crews is to use the `crewai create flow <name_of_flow>` command. This will create a new CrewAI project for you that includes a folders for your Crews.
