📝 docs(initialize): add empty __init__.py file to initialize directory
The initialize directory was added to the project, but it was missing an __init__.py file. This file is necessary to make the directory a package and allow importing modules from it. An empty __init__.py file was added to the directory to fix this issue.
A new PineconeIcon component was added to the nodeIcons object in utils.ts. This allows the Pinecone icon to be used in the frontend application. The icon was added to improve the visual representation of the Pinecone node in the application.
🐛 fix(process.py): correctly update template_data with tweak_value
The file extension is no longer included in the saved file name to avoid issues with file extensions that may not be supported. In process.py, the tweak_value is now correctly updated in the template_data dictionary. The key is now set to "value" for all tweaks except for "file_path" where the key is set to the name of the tweak.
✨ feat(loading.py): add persist parameter to Chroma vector store instantiation to enable persistence of vector store
The persist parameter is now extracted from the params dictionary before instantiating the Chroma vector store. This improves readability and reduces the complexity of the code. The persist parameter is now added to the Chroma vector store instantiation to enable persistence of the vector store. This allows the vector store to be reused across multiple sessions, improving performance and reducing the time required to load the vector store.
🐛 fix(vectorstores.py): add persist field to Weaviate vector store type
The `VectorStoreFrontendNode` class now supports the Chroma vector store type. A new boolean field `persist` has been added to the Chroma vector store type. The `add_extra_fields` method has been updated to add the `persist` field to the Chroma vector store type. The `format_field` method has been updated to include the `persist` field in the basic fields. Additionally, the `add_extra_fields` method has been updated to add the `weaviate_url` field to the Weaviate vector store type.
The changes in this commit are purely cosmetic. The indentation and formatting issues in the code have been fixed to improve readability and maintainability.
The QueryCheckerTool class was renamed to QuerySQLCheckerTool to match the correct class name. This change ensures that the correct class is being used and avoids any potential errors that may arise from using the wrong class name.
The save_uploaded_file function now uses the folder_name parameter instead of file_name to improve semantics. The appdirs library is now used to get the user cache directory and a folder for langflow cache is created. The sha256 hash of the file content is now used as the file name to avoid collisions and improve security. A folder is now created for each flow_id in the save_uploaded_file function. The code that deletes files after loading in the instantiate_documentloader function has been removed as it is unnecessary and can cause issues.
🐛 fix(endpoints.py): change file_name parameter to folder_name in save_uploaded_file function
🔒 chore(utils.py): use appdirs to get user cache directory and create a folder for langflow cache
🔒 chore(utils.py): use sha256 hash of file content as file name to avoid collisions and improve security
🔒 chore(utils.py): create folder for each flow_id in save_uploaded_file function
The flows and tabIndex variables were not being used in the component, so they were removed. The tabId variable from the TabsContext is now being used instead to upload the file to the correct tab.
✨ feat(endpoints.py): add UploadFileResponse schema to standardize upload file response
The client_id parameter in the create_upload_file endpoint has been renamed to flow_id to improve semantics. The UploadFileResponse schema has been added to standardize the response of the create_upload_file endpoint. The response now includes the flowId and file_path fields.
✨ feat(utils.py): remove unused functions and add docstring to save_uploaded_file function
The try-except block in the create_upload_file function handles exceptions that may occur when saving uploaded files. The save_uploaded_file function now has a docstring that explains its purpose and returns the path to the saved file. The unused functions save_cache and load_cache have been removed.
The file upload functionality has been refactored to use a separate function called uploadFile, which is imported from the API controller. This improves the separation of concerns and makes the code more modular.
The uploadFile function allows the user to upload a file to the server. It takes in a file and an ID of the flow to upload the file to. The function creates a FormData object and appends the file to it. It then sends a POST request to the server with the FormData object as the body. The server responds with a Promise containing the response data.
This commit adds a new type definition for the UploadFileTypeAPI, which includes a single property file_path of type string. This type will be used to define the response of an API endpoint that handles file uploads.
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.
