Prerequisite: Please install Node.js (version 19 or higher) before proceeding.
Ensure you have a codebase ready to index.
Follow these steps to install and run Graptor on your codebase: Step 1: Install Graptor: 
npm i graptor
Step 2: Navigate to the codebase folder or specific directory: 
graptor run <folder name>
Graptor internally Parses your code with ASTs and Builds a semantic code graph. At this point, code-graph.json is created. You can stop here if you only need the code graph. Step 3: Generate vector embeddings: Do you want to embed these chunks into vectors now? (Y/n) If you choose Yes, you can select:
  • Open-source model (default, no API key needed)
  • Your own model (coming soon!)
Graptor then converts each code chunk into a vector embedding and saves the result in embeddigs.json Now, These embeddings are ready to use in a vector database or with LLM agents.
