A minimal guide to building a code-level graph from a repository and searching it. The pipeline parses your repo, extracts code entities and dependencies, and optionally processes non-code docs alongside. Before you start:
  • Complete Quickstart to understand basic operations
  • Ensure you have LLM Providers configured
  • Have a local repository path (absolute or relative)

​
What Code Graph Does

  • Scans a repo for supported languages and builds code nodes/edges (files, symbols, imports, call/dependency links)
  • Optional: includes non-code files (markdown, docs) as a standard knowledge graph
  • Use standard search types like SearchType.GRAPH_COMPLETION or SearchType.CHUNKS to query the code graph

​
Code in Action

import asyncio
import cognee
from cognee import SearchType
from cognee.api.v1.cognify.code_graph_pipeline import run_code_graph_pipeline

async def main():
    repo_path = "/path/to/your/repo"  # folder root

    # Build the code graph (code only)
    async for _ in run_code_graph_pipeline(repo_path, include_docs=False):
        pass

    # Ask a code question
    results = await cognee.search(query_type=SearchType.GRAPH_COMPLETION, query_text="Where is Foo used?")
    print(results)

asyncio.run(main())
This simple example uses a basic repository for demonstration. In practice, you can process large codebases with multiple languages and complex dependency structures.

​
What Just Happened

​
Step 1: Build the Code Graph

async for _ in run_code_graph_pipeline(repo_path, include_docs=False):
    pass
This scans your repository for supported languages and builds code nodes/edges. The pipeline handles file parsing, symbol extraction, and dependency analysis automatically.

​
Step 2: Search Your Code

results = await cognee.search(query_type=SearchType.GRAPH_COMPLETION, query_text="Where is Foo used?")
Use SearchType.GRAPH_COMPLETION to ask code-aware questions about your repository. This searches through the extracted code structure, not just text content.

​
Include Documentation (Optional)

Also process non-code files from the repo (slower, uses LLM for text): 
async for _ in run_code_graph_pipeline(repo_path, include_docs=True):
    pass
This processes markdown files, documentation, and other text files alongside your code, creating a comprehensive knowledge graph.

​
Advanced Options

async for _ in run_code_graph_pipeline(
    repo_path,
    include_docs=False,
    excluded_paths=["**/node_modules/**", "**/dist/**"],
    supported_languages=["python", "typescript"],
):
    pass
  • excluded_paths: List of paths (globs) to skip, e.g., tests, build folders
  • supported_languages: Narrow to certain languages to speed up processing

​
Visualize Your Graph (Optional)

from cognee.api.v1.visualize.visualize import visualize_graph
await visualize_graph("./graph_code.html")
Generate an HTML visualization of your code graph to explore the structure and relationships.

​
What Happens Under the Hood

run_code_graph_pipeline(...) automatically handles:
  • Repository scanning and file parsing
  • Code entity extraction (functions, classes, imports, calls)
  • Dependency analysis and relationship mapping
  • Database initialization and setup
  • Optional documentation processing with LLM
Once complete, your code graph is ready for search and analysis.
