🐛 fix(buildTrigger): handle error response from server when starting a build
The ProgressBarComponent import was removed as it was not being used. The error handling was improved to handle the case where the server returns an error response when starting a build. The error message is now displayed to the user and the build state is reset.
🐛 fix(chat.py): fix StreamData class import statement
✨ feat(chat.py): add progress tracking and node building events to stream_build function
The unused import statement has been removed to improve code readability. The StreamData class import statement has been fixed to avoid errors. Progress tracking and node building events have been added to the stream_build function to provide more information to the user about the build process.
The StreamData model is added to represent the data that is streamed from the server. The __str__ method is added to improve the readability of the stream data by returning a formatted string that includes the event and data attributes.
The buildTrigger component was updated to use progress state instead of myValue to better represent the progress of the building process. This change allowed us to make improvements in the way progress is tracked, which will improve the user experience.
🐛 fix(chat.py): catch exception when building graph and yield error message
When the flow_id is invalid, the yield statement should return an error message instead of data. Additionally, when building the graph, an exception could occur, so we added a try-except block to catch any exceptions and yield an error message instead of data.
- The radial progress now displays the percentage value correctly.
- In the build trigger, we now properly handle the end of a stream event and fixed an issue with the RadialProgressComponent when isBuilding is true.
This commit adds a value state to the RadialProgress component, replacing the progressContext previously used. It also removes the progressContext, as it is no longer needed.
The conditional statement in the update_flow function was incorrect. The if statement was checking for the opposite of what was intended. The fix changes the if statement to check for the correct condition.
✨ feat(chat.py): add progress logging to stream_build function
The variable node was renamed to vertex to improve semantics and consistency with the naming conventions. Progress logging was added to the stream_build function to provide feedback to the user on the progress of the build process.
🐛 fix(index.tsx): fix typo in setSuccessData function call
✨ feat(index.tsx): add success logging to handleBuild function
A typo in the setSuccessData function call was fixed. Success logging was added to the handleBuild function to provide feedback to the user on the success of the build process.
The input parameter now accepts a Path object in addition to a string or dictionary. This improves the flexibility of the function and allows for easier file handling.
The `getPythonCode` function now accepts a `tweaks` parameter which is used to customize the behavior of the flow. The `buildTweaks` function is called to generate the `tweaks` object which is then passed to the `load_flow_from_json` function. This allows for more flexibility in the usage of the flow.
The fix_memory_inputs function was refactored to reduce nesting and improve readability. The function now checks if the langchain_object has a memory attribute and if it is not None before proceeding. The try-except block was also refactored to reduce nesting.
✨ feat(process.py): add input validation to process_tweaks function
The process_tweaks function has been refactored to improve readability and maintainability. The apply_tweaks function has been added to apply the tweaks to the node. The validate_input function has been added to validate the input parameters. The process_tweaks function now raises a ValueError if the input is not in the expected format.

🧪 test(loading.py): add test case for loading a flow from a JSON file and applying tweaks
🧪 test(loading.py): remove unused import statement
The import statement for Chain in base.py is now more explicit and imports it from langchain.chains.base instead of importing it from langflow.graph.vertex.types. The load_flow_from_json function in process.py now accepts either a JSON file path or a JSON object. The print statement in process_tweaks function has been removed. The load_flow_from_json function in process.py now accepts an optional tweaks parameter. The return type of the build method in the Graph class has been changed from List[Vertex] to Chain. A new test case has been added to loading.py to test loading a flow from a JSON file and applying tweaks. An unused import statement has been removed from loading.py.
✨ feat(__main__.py): add support for running Langflow on MacOS and Linux using gunicorn
The changes add support for running Langflow on Windows by using uvicorn instead of gunicorn. This is because Windows doesn't support gunicorn. The changes also add support for running Langflow on MacOS and Linux using gunicorn. This is because MacOS requires an env variable to be set to use gunicorn.
The prepare-commit-msg git hook was removed from the frontend directory. This hook was not being used and was not necessary for the project's development workflow.
The conditional statement was checking if "nodes" is in "graph_data['data']" instead of checking if "nodes" is in "graph_data". This fix ensures that the correct data is processed and avoids potential errors.
The only change in this commit is the removal of an unnecessary newline at the beginning of the file. This improves the code's readability and consistency.
🔥 chore(main.py): remove unused imports and variables
The `flow_data_store` variable in `chat.py` was missing a type hint, which was added to improve code readability and maintainability. In `main.py`, unused imports and variables were removed to improve code cleanliness.
The changes in headerComponent remove unused imports and update the header text to use a constant instead of a hardcoded string. The constant is added in constants.tsx. The MainPage component is updated to use the constant for the header text in the user projects section. This improves code readability and maintainability.
🎨 style(headerComponent): remove unused imports and update header text to use constant
✨ feat(constants.tsx): add constant for header text in user projects section
✨ feat(main.py): remove static_path argument from create_app function
The fix to the issue where the app was not serving the index.html file when a 404 error occurred was done by adding an exception handler to the app that returns the index.html file when a 404 error occurs. The create_app function was modified to remove the static_path argument as it was not being used in the function.
The keys in the types object were reversed to avoid overlap with the tool world. This was done by modifying the reduce function in the TypesProvider component.
✨ feat(__main__.py): add support for health check endpoint and use it to check server status
The `serve` function now checks if the specified port is in use and gets a free port if it is. This ensures that the server can run on a free port and avoids conflicts with other running applications. The `serve` function also now uses a health check endpoint to check the status of the server. The `setup_static_files` function now takes a `Path` object instead of a string for the static files directory. The `create_app` function now takes a `Path` object instead of a string for the static files directory.
Update the search placeholder to be more general, from 'Search Nodes' to 'Search', in the extra sidebar component, and update the collection description from 'Download or upload your complete project collection' to 'Download or upload your collection' in the main page.
The API URL path was incorrectly spelled as "/ap1/v1/predict" instead of "/api/v1/predict". This commit fixes the typo to ensure that the correct API endpoint is used.
Changed the error message in the build trigger component to clarify which components need to be checked before retrying. Updated the list to include instructions on how to inspect the component status.
🐛 fix(process.py): fix KeyError when processing tweaks on graph_data with missing "data" key
The try-except block added in endpoints.py catches any exceptions that occur when processing tweaks and logs them to the logger. This helps with debugging and identifying issues with the processing of tweaks. In process.py, a KeyError was fixed by checking if the "data" key exists in the graph_data dictionary before accessing the "nodes" key.
refactor(App.tsx): remove redundant code that initializes the version state variable and fetches the version number from the API in FlowPage component instead
