Can I add collections without API Key?

[junaid33]

Hello, I recently upgraded my self-hosted version of LangFlow, but the example collections are gone. I see a store now, but I need a key to add any of those examples? Can I upload those collections without a key? I'd like to use LangFlow without any external APIs.

Hey @junaid33, great to see you back in the LangFlow community! I hope everything is going well for you. Let's dive into your question.

Yes, you can add collections to your self-hosted version of LangFlow without an API key. The LangFlow code includes an endpoint for uploading files that contain flows. This endpoint is defined in the function upload_file in the file src/backend/langflow/api/v1/flows.py. This function reads the contents of the uploaded file, parses it as JSON, and creates a list of flows from the parsed data. It then sets the user_id for each flow to the ID of the current user and calls the create_flows function to add the flows to the database. The function does not require an API key and does not use any external APIs.

The collections that you upload should be in the format of a list of flows. Each flow in the list should be a dictionary that matches the FlowCreate schema. Here is a sample format:

[
    {
        "key1": "value1",
        "key2": "value2",
        ...
    },
    {
        "key1": "value1",
        "key2": "value2",
        ...
    },
    ...
]

Each dictionary in the list represents a flow and should contain keys and values that match the FlowCreate schema. The exact keys and values would depend on the specifics of the FlowCreate schema.

The FlowCreate schema is a subclass of the FlowBase schema. It inherits all the fields from FlowBase and adds an additional field user_id. Here is the exact structure:

• name: A string field that is indexed. This is a required field.
• description: An optional string field that is also indexed. It defaults to None.
• data: An optional dictionary field that defaults to None. It must be a valid JSON containing keys "nodes" and "edges".
• is_component: An optional boolean field that defaults to False.
• updated_at: An optional datetime field that defaults to the current UTC time. It can be serialized to JSON.
• folder: An optional string field that defaults to None.
• user_id: An optional UUID field that defaults to None.

This schema is used when creating a new flow. The user_id field is used to associate the flow with a user. You can find more details about this schema in the file src/backend/langflow/services/database/models/flow/model.py.

I hope this helps! If you have any other questions, feel free to ask.

Best,
Dosu

For example flows you can clone this repo and import the json flows from this repos examples directory as projects:

https://github.com/langflow-ai/langflow_examples.

You can also google search: site:github.com "langflow" flow json examples
