* feat: Add dual output support to Agent component with structured JSON parsing
## Summary
- Add "Structured Response" output alongside existing "Response" output
- Filter out conflicting json_mode field from OpenAI inputs
- Implement robust JSON parsing with fallback handling
## Changes Made
### Agent Component (agent.py)
- Add second output: "Structured Response" (Data type) with tool_mode=False
- Filter json_mode from OpenAI inputs to prevent UI conflicts
- Add json_response() method with multi-stage JSON parsing:
- Direct JSON parsing for valid responses
- Regex extraction for embedded JSON in text
- Graceful error handling with diagnostic info
- Share execution between outputs (no duplicate agent runs)
- Fix model building to handle missing json_mode attribute
### Tests (test_agent_component.py)
- Add 9 comprehensive test cases covering:
- Dual output structure validation
- Input filtering verification
- JSON parsing (valid, embedded, error cases)
- Model building without json_mode
- Shared execution efficiency
- Frontend node structure
- Component initialization
## Benefits
- Users get both Message and Data output types to choose from
- Clean UI without confusing duplicate JSON toggles
- Robust JSON parsing handles various response formats
- Efficient single-execution approach
- Maintains backward compatibility

* feat: implement file upload API snippet generation
Add proper two-step file upload support for API code generation:
- Detect file tweaks in ChatInput (string), File/VideoFile (path/file_path)
- Generate step-based cURL commands with separate copy buttons
- Fix ChatInput to use correct /api/v1/run endpoint with tweaks structure
- Update JavaScript and Python generators with proper endpoints and payloads
- Support dynamic node IDs and processedPayload values
- Implement step parsing UI for cURL with proper formatting
Co-Authored-By: Automagik Genie <genie@namastex.ai>
* fix: update JavaScript API snippet generator for native Node.js
Replace browser-based FormData approach with native Node.js http module
- Use built-in fs, http, and path modules instead of browser APIs
- Manually construct multipart/form-data payloads
- Add proper error handling and HTTP request helpers
- Support both ChatInput and File/VideoFile upload scenarios
- Maintain authentication header support
Co-Authored-By: Automagik Genie <genie@namastex.ai>
* fix: include output_type, input_type, input_value in File component cURL snippets
File/VideoFile components were missing the required payload fields when
generating cURL commands, causing flows to fail execution. Added the missing
fields to match the working pattern used in Chat Input components.
Co-Authored-By: Automagik Genie <genie@namastex.ai>
* fix: include output_type, input_type, input_value in Python and JavaScript File component snippets
File/VideoFile components were missing the required payload fields in Python
and JavaScript generators, matching the fix applied to cURL snippets.
Co-Authored-By: Automagik Genie <genie@namastex.ai>
* fix: use 'path' field for File components instead of 'file_id'
File components require the 'path' field from v2 upload response as an array,
not 'file_id'. Updated all three generators:
- Changed file_id to file_path variable extraction
- Changed "file_id": value to "path": [value] in tweaks
- Updated placeholder text for consistency
This fixes the "No files to process" error in File components.

🐛 (api.tsx): fix issue where Authorization header was not being set correctly for internal requests
💡 (api.tsx): improve logic to set Authorization header only for internal requests and add custom headers for all requests
* test: enhance agent component tests and add new fixture for database-less sessions
- Added `use_noop_session` fixture to facilitate testing without a database.
- Expanded `TestAgentComponent` with new tests for agent responses using the Calculator tool and validation across all OpenAI and Anthropic models.
- Updated `test_component.py` to include tests for message sending without a database, ensuring proper event handling and message integrity.
- Refactored existing tests for clarity and consistency.
* fix: enhance user retrieval logic in get_or_create_super_user and teardown_superuser functions
- Updated user retrieval in both functions to handle different result types from the database query, ensuring robustness against unexpected return values.
- Added checks for `first()` method and list type to improve error handling and maintainability.
* feat: add support for no-op database operations in settings
- Introduced `use_noop_database` configuration option to disable all database operations, controlled by the `LANGFLOW_USE_NOOP_DATABASE` environment variable.
- Updated the `use_noop_session` fixture to reflect the new environment variable for testing without a database.
* feat: implement NoopSession for database-less operations
- Added NoopSession class to provide a no-operation database session, allowing for testing and operation without a real database connection.
- Updated DatabaseService to utilize NoopSession when the `use_noop_database` setting is enabled, ensuring all database operations are disabled in this mode.
- Enhanced error handling and logging for session management, improving robustness in scenarios where the database is not in use.
* refactor: update import paths for NoopSession in test files
- Changed import path for NoopSession from `langflow.services.database.service` to `langflow.services.database.session` in both `test_agent_component.py` and `test_component.py`.
- This refactor improves code organization and aligns with recent changes in the project structure.
* feat: enhance NoopSession with result handling methods
- Added an internal _NoopResult class to the NoopSession, providing methods `first()`, `all()`, and `one_or_none()` for better handling of no-operation results.
- This enhancement improves the usability of NoopSession in testing scenarios by mimicking expected database query behaviors.
* refactor: improve logging for NOOP database session
- Changed the log level from warning to info for the NOOP database session message in the DatabaseService class.
- This adjustment enhances clarity in logging, indicating that all DB operations are disabled without implying an error condition.
* docs: improve docstring formatting for custom_component_update function
- Reformatted the docstring for the custom_component_update function to enhance readability by breaking long lines into multiple lines.
- This change improves documentation clarity, making it easier for developers to understand the function's purpose and behavior.
* docs: add LANGFLOW_USE_NOOP_DATABASE environment variable documentation
- Introduced documentation for the new LANGFLOW_USE_NOOP_DATABASE environment variable, which allows users to enable a no-op database mode, avoiding database connections and operations.
- This addition enhances the clarity of configuration options available for Langflow, aiding users in understanding how to run flows without a database.
* refactor: move NOOP database session logging to settings
- Removed the logging statement from the DatabaseService class and added it to the `set_use_noop_database` field validator in the Settings class.
- This change centralizes the logging for the NOOP database session, improving code organization and ensuring that the message is logged whenever the setting is applied.
* docs: Add heading and codeblock events for segment
* docs: Update scroll event names
* docs: improve capture of code block language
* docs: ensure code block language capture for mobile
* refactor: update config response handling and import structure
- Moved EventManager import to the correct module path.
- Refactored get_config endpoint to utilize ConfigResponse.from_settings for improved clarity and maintainability.
- Updated ConfigResponse to include a class method for instantiating from Settings, enhancing the encapsulation of configuration logic.
