Serve Flows as UI

Expose your QType flows through an interactive web interface using the qtype serve command.

Command

qtype serve <file.qtype.yaml> [--host HOST] [--port PORT] [--reload]

Explanation

• Interactive UI: Web interface at http://localhost:8000/ui (redirects from root /)
• Complete Flows: Display as forms with input fields and output display
• Conversational Flows: Display as chat interfaces with message history
• Auto-generated: UI is automatically created based on flow inputs/outputs
• --reload: Auto-reload on file changes during development
• --host/--port: Override default host (localhost) and port (8000)

Example

qtype serve examples/tutorials/01_hello_world.qtype.yaml

Then visit http://localhost:8000/ui to interact with your flow through the web interface.

The UI automatically generates:

• Input fields based on variable types
• Submit button to execute the flow
• Output display for results
• Error messages if execution fails
