🔀 refactor(base.py): import Chain from langchain.chains.base instead of importing it from langflow.graph.vertex.types
🔀 refactor(process.py): remove print statement from process_tweaks function
🔀 refactor(process.py): change load_flow_from_json function signature to accept optional tweaks parameter
🔀 refactor(process.py): change return type of build method in Graph class from List[Vertex] to Chain
🧪 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.
The changes in this commit are purely cosmetic. The code has been reformatted to improve readability and consistency. Unnecessary lines have been removed to make the code more concise.
This commit adds tests for the process_tweaks function in the langflow.processing.process module. The tests cover the following scenarios:
- No tweaks are applied to the graph data
- A single tweak is applied to the graph data
- Multiple tweaks are applied to the graph data
- A tweak is applied to a non-existent parameter in the graph data
The tests ensure that the function processes the tweaks correctly and returns the expected result.
The unused imports and exception handling for WebSocketDisconnect and WebSocketException were removed from the chat.py file. The code was reformatted to improve readability.
🔥 refactor(chat.py): remove unused imports and exception handling
🚨 test(test_websocket.py): add tests for build init, stream, and websocket endpoint
The `basic_graph_data` fixture is added to load the basic example data. The `test_init_build`, `test_stream_build`, and `test_websocket_endpoint` tests are added to test the build init, stream, and websocket endpoint. The `test_websocket_endpoint_after_build` test is added to test the websocket endpoint after the build.
The test_chat_history test is outdated and no longer works with the current implementation of the application. It has been removed to avoid confusion and to keep the test suite clean.
🐛 fix(interface/loading.py): fix custom_node instantiation to handle classes without initialize method
✨ feat(template/frontend_node/prompts.py): change type_name to match class name
✨ feat(template/frontend_node/tools.py): change type_name to match class name
🔥 chore(test_agents_template.py): remove test_agents_settings and update initialize_agent test
The vertex_type assignment in the Vertex class was not handling uppercase template types correctly. This has been fixed to handle both uppercase and lowercase types. The custom_node instantiation in the instantiate_class function was not handling classes without an initialize method correctly. This has been fixed to instantiate the class directly if the initialize method is not present. The type_name in the ZeroShotPromptNode and PythonFunctionToolNode classes have been changed to match the class name. The test_agents_settings test has been removed as it is no longer necessary and the initialize_agent test has been updated to match the new AgentInitializer class name.
🧪 test(test_database.py): add test case for creating flows without a flow
The flow field is now optional to allow creation of flows without a flow. This is useful when creating a flow that will be populated later. A test case was added to ensure that flows can be created without a flow.
🐛 fix(llms.py): add name check before checking if "azure" is in name.lower()
🔨 refactor(test_database.py): rename updated_flow_style variable to to_update_flow_style for clarity
The update_settings function now has an optional database_url parameter to allow for more flexibility in updating settings. The llms.py file now checks if the name variable is not None before checking if "azure" is in name.lower(). In test_database.py, the updated_flow_style variable is renamed to to_update_flow_style for clarity.

🚀 feat(loading.py): add support for PythonFunction node type
🚀 feat(constants.py): add PythonFunction to CUSTOM_TOOLS
🚀 feat(custom.py): add PythonFunction class
🚀 feat(frontend_node/tools.py): add PythonFunctionNode class
🧪 test(test_custom_types.py): add test for PythonFunction class
🧪 test(test_llms_template.py): comment out tests for AzureOpenAI and AzureChatOpenAI
The changes add support for a new node type, PythonFunction, which allows users to define a Python function to be executed. The node type is added to CUSTOM_NODES in customs.py, and support for the node type is added to loading.py. The node type is also added to CUSTOM_TOOLS in constants.py, and the PythonFunction class is added to custom.py. The PythonFunctionNode class is added to frontend_node/tools.py. Tests for the new PythonFunction class are added to test_custom_types.py. Tests for AzureOpenAI and AzureChatOpenAI are commented out in test_llms_template.py.
The API endpoint URLs have been updated to include the version number to improve the API's versioning and maintainability. The changes were made to the server.ts file and the tests that use the API endpoints.
🐛 fix(tests): update API endpoint paths in test files
The API endpoint paths in the test files were outdated and have been updated to reflect the current API version. This ensures that the tests are running against the correct endpoints and that the tests are up-to-date with the current API version.
✨ feat(flow.py): add validator to ensure flow field is a valid JSON object with required fields
The flow field in the FlowBase model has been changed from a string to a dictionary to allow for JSON data. A validator has been added to ensure that the flow field is a valid JSON object with the required fields. The tests have been updated to reflect these changes.
There are still some rough edges due to underlying langchain and
openai API limitations, e.g. hwchase17/langchain#3769 and
openai/openai-python#411. Notably, you can't use the Azure and
non-Azure node types in the same server, since there's global openai
configuration needed to choose between the two. So it's probably best
to still leave the Azure node types commented out in the default
config. But with this PR, if you uncomment those nodes and start the
server with OPENAI_API_TYPE=azure, you will have working Azure nodes.
✨ feat(database.py): add default argument to json.dumps to handle datetime objects
🚨 test(database.py): add tests for batch flow creation, file upload, and file download
The fix in database.py handles the case where the data dictionary does not contain the "flows" key. This is important because the code assumes that the "flows" key is present and will raise an exception if it is not. The fix adds a check to see if the "flows" key is present and if not, it creates a new FlowListCreate object with the data as a list of FlowCreate objects.
The feature in database.py adds a default argument to the json.dumps function to handle datetime objects. This is important because the default json encoder does not handle datetime objects and will raise an exception if it encounters one.
The tests in test_database.py cover the batch creation of flows, uploading a file containing flows, and downloading a file containing flows. These tests ensure that the endpoints are working as expected and that the data is being handled correctly.
The changes include:
- Moved the `Edge` class to a new `edge` package
- Moved the `Graph` class to a new `graph` package
- Moved the `Node` class to a new `node` package
- Moved the `VectorStoreNode` class to the `node/types.py` module
- Moved the `Edge`, `Graph`, and `Node` classes to their respective `base.py` modules
- Added an `__init__.py` file to each package to allow for importing of classes
- Added a `constants.py` module to the `graph` package to store constants used in the `Graph` class
- Refactored the `Graph` class to use the new `Node` and `Edge` classes
- Refactored the `Graph` class to use a dictionary to map node types to their respective classes
- Refactored the `Graph` class to remove invalid nodes from the graph
- Refactored the `Graph` class to handle the LLM node within the graph
- Refactored the `Graph` class to build the nodes before building the edges
- Refactored the `Graph` class to use the `get_node` method to find nodes by id
- Refactored the `Graph` class to use the `get_node_neighbors` method to find the neighbors of a node
- Refactored the `Graph` class to use the `get_children_by_node_type` method to find the children of a node based on the node type
These changes improve the modularity and maintainability of the `langflow` package by separating the classes into their respective packages and modules. The changes also make it easier to add new node types to the `Graph` class by using a dictionary to map node types to their respective classes.
