- Refactored the tools module to improve code readability and maintainability.
- Fixed import statements in the constants module to correctly import modules.
- Updated documentation and added comments for better understanding of the code.
The load_params() function is added to load the parameters from the environment variables. This allows for more flexibility and configurability of the application by allowing the parameters to be set via environment variables.
feat(codeAreaModal): add support for displaying error details and traceback in the error tab for better debugging
refactor(codeAreaModal): improve code readability and formatting for better maintainability
- Extracted the logic for removing unwanted base classes to a separate method called `process_base_classes`.
- Created a list `CLASSES_TO_REMOVE` which contains the names of the base classes to be removed.
- Updated `to_dict` method to call `process_base_classes` before generating the dict representation of the frontend node.
- Added a new method `process_base_classes` which removes the unwanted base classes from the list of base classes.
- The method `process_base_classes` updates the `base_classes` list, removing any base classes present in `CLASSES_TO_REMOVE`.
This commit enhances the code by separating the concerns of base class removal logic and dict representation generation.
🌟 feat(__main__.py): add support for environment variables to configure serve function
The serve function in __main__.py has been refactored to use environment variables for configuration options. The following configuration options now support environment variables: host, workers, port, log_level, log_file, path, open_browser, and remove_api_keys. This change allows for greater flexibility and easier configuration of the serve function by using environment variables instead of command line options.
- Modifies the `CustomComponent` class to handle errors using `HTTPException` from FastAPI
- Removes the unused `HTTPExceptionWithTraceback` class
- Updates the error response format with `err.msg` and `traceback.format_exc()`
This commit adds a new class `HTTPExceptionWithTraceback` that extends `HTTPException` from the `fastapi` module. This new class includes a `traceback` attribute. Additionally, in the `extract_class_info` method of the `CustomComponent` class, a try-except block is added to catch any syntax errors raised by parsing the provided code. If a syntax error is encountered, an HTTPException is raised with the error message and traceback.
The environment variable name is changed from LANGFLOW_DATABASE_URL to langflow_database_url to maintain consistency with the naming conventions used in the codebase. This ensures that the code is more readable and easier to understand.
The `cache` option has been changed to use the `LANGFLOW_LANGCHAIN_CACHE` environment variable instead of `LANGCHAIN_CACHE` for clarity and consistency. Similarly, the `database_url` option now uses the `LANGFLOW_DATABASE_URL` environment variable instead of the previous behavior of using a local SQLite database by default. This change allows for more flexibility in configuring the cache and database connections.
🔧 chore(utils.py): refactor `setup_llm_caching` to extract cache setup logic into a separate function for better modularity and readability
The variable `cache_class` has been renamed to `cache_type` to improve clarity and consistency with the naming conventions. The `setup_llm_caching` function has been refactored to extract the cache setup logic into a separate function called `set_langchain_cache`. This improves modularity and readability of the code.
style(DisclosureComponent): update Icon class to use text-primary class for consistent styling
style(FlowPage): remove logspace-icon-text class and update the structure of the icon and text elements for better alignment and spacing
The `database_url` setting is now declared as an optional string (`Optional[str]`) instead of a required string. This change allows the application to handle cases where the `database_url` is not provided, providing more flexibility in the configuration.
The os module is imported to make use of the os.getenv() function. The loading of the environment variables is refactored to check for the presence of the "langflow_database_url" environment variable and use it as the value for the database_url variable if it is not provided. This allows for more flexibility in configuring the database URL. Additionally, the loading of environment variables is refactored to allow overriding with a .env file if the env_file parameter is provided. This allows for easier configuration management.
🔧 chore(__main__.py): import os module and refactor loading of environment variables
The noqa comments have been added to the import statements to ignore the linting errors raised by the linter. This ensures that the linting errors related to the imports are ignored and the code can be properly executed without any issues.
✨ feat(base.py): add error handling when creating database and tables to provide more informative error messages
The code now checks if the `settings.database_url` is provided and raises a `RuntimeError` if it is not. This ensures that the application does not attempt to create a database connection without a valid URL. Additionally, error handling has been added when creating the database and tables. If an exception occurs during the creation process, an error message is logged and a `RuntimeError` is raised with a more informative error message. This helps in identifying and resolving any issues related to the database creation process.
This commit adds support for dynamic fields in the template field creator class. The "dynamic" attribute has been added to the class definition and its default value is set to False.
This commit adds a dynamic field to the code field in the types module. The dynamic field is set to True, indicating that the field allows updates.
refactor: Remove dynamic field from FrontendNode class
In the FrontendNode class of the base module, the dynamic field has been removed. This change aligns with the removal of the dynamic field in the types module.
refactor: Remove dynamic field from CustomComponentNode class
The dynamic field has been removed from the CustomComponentNode class in the tools module. This aligns with the removal of the dynamic field in the FrontendNode class.
🐛 fix(loading.py): remove unnecessary None default value for file_filter parameter
The unused import statement from langchain.prompts.base has been removed to improve code cleanliness. The None default value for the file_filter parameter in the instantiate_documentloader function has been removed as it is unnecessary and can be safely assumed that the parameter will always be provided.
💡 chore(main.py): clean up code by removing an unused endpoint and a template_node variable that is no longer needed
The /dynamic_node endpoint and the template_node variable are no longer used in the application and can be safely removed. This improves code cleanliness and reduces unnecessary complexity.
🐛 fix(base.py): fix __eq__ method in Edge class to correctly compare objects
The add_edge method in the Vertex class has been modified to prevent adding duplicate edges. Now, before adding an edge, it checks if the edge already exists in the edges list to avoid duplicates.
The __eq__ method in the Edge class has been fixed to correctly compare objects. It now compares the string representation of the objects to determine equality, ensuring that the comparison is accurate.
- The `build` method of `MyPythonClass` is modified to accept an `openai_api_key` parameter instead of using a hardcoded value.
- This change allows for dynamic usage of different API keys when constructing an instance of `ConversationChain`.
- The `my_conversation` method now takes `openai_api_key` as an argument and uses it to initialize the `llm` instance of `OpenAI`.
- The `build` method simply delegates the `openai_api_key` argument to the `my_conversation` method and returns the resulting `ConversationChain` instance.
- Updatethe `get_function_custom` function to use the `validate.extract_class_name` function to extract class name from the `code` parameter.
- Modify `instantiate_tool` function to update the `class_object` with the return value of `get_function_custom` and call the `build` method on the instantiated object with the remaining params.
- Add a new function `extract_class_name` in the `validate` module to extract class name from the `code` parameter.
The code now checks if the variable already exists in the template and if so, sets the new field value with the old value. This ensures that the existing value is preserved when adding new variables to the template.
The multiline option is added to the input_variables field in the add_new_variables_to_template function. This allows the field to accept multiline input, which can be useful in certain scenarios where multiple lines of text need to be entered.
✨ feat(GenericNode/index.tsx): improve readability and maintainability by extracting repeated class names into variables
The class order in the div element has been fixed to ensure the correct styling is applied. Repeated class names have been extracted into variables to improve readability and maintainability of the code.
- Added a dynamic flag to CustomComponentNode class in tools.py for enabling dynamic behavior.
- This flag allows for flexibility in executing the Python class.
- The flag defaults to True.
Previously, the `build` method in the `MyPythonClass` class had an argument named `name`, which could be confusing. This commit changes the argument name to `my_custom_input` to improve readability and clarity.
