For those new to Cognee, a demo notebook and video tutorial are available, and community support is accessible via Discord. Cognee README.md
Frontend Components
The frontend of Cognee is built using React, with various components designed to enhance user interaction and data management. The home page component utilizes hooks like useDatasets and useNotifications to manage datasets and user notifications effectively. It provides functions to open and close dataset views, add data, and initiate the 'cognification' process. The UI includes a settings modal, datasets view, and data view, all styled using CSS modules. Home Page Component
The AddStep component facilitates file uploads in a multi-step process, using hooks like useState and useCallback to manage state and behavior. It ensures a smooth user experience by handling file uploads, displaying file details, and providing navigation to the next step. AddStep Component
The WizardPage component manages a multi-step wizard interface, guiding users through steps like 'config', 'add', 'cognify', and 'explore'. It uses state management to navigate between steps and includes a settings modal for configuration. WizardPage Component
Backend and API
Cognee's backend is powered by a FastAPI server, providing endpoints for managing datasets, user authentication, and settings. The server is configured with CORS middleware and includes exception handling for request validation errors. It supports operations like retrieving, deleting, and adding datasets, as well as cognitive processing and searching within datasets. Cognee API Client
The add function processes various data inputs, organizing them into datasets for further processing. It supports file paths, directories, or text inputs, ensuring efficient data organization and storage. Add Function
The cognify function processes datasets using a series of tasks to transform and analyze data, generating knowledge graphs and summarizing text using machine learning models. Cognify Function
Database Adapters
Cognee integrates with various databases through specialized adapters. The Neo4jAdapter provides an interface for interacting with a Neo4j graph database, supporting operations like adding, deleting, and querying nodes and edges. Neo4jAdapter
The LanceDBAdapter interfaces with a LanceDB vector database, offering methods for embedding data, managing collections, and performing search operations. LanceDBAdapter
The PGVectorAdapter handles vector embeddings in a database using SQLAlchemy and pgvector, supporting operations like creating, retrieving, and searching data points. PGVectorAdapter
