Getting Started with CentR

CentR is developer middleware that reduces repeated repository exploration by providing task-relevant project intelligence, project memory, and cross-project learning.

Prerequisites

Node.js >= 20.0.0 and npm are required. CentR uses native SQLite 3 bindings with zero mandatory cloud AI services.

1. Global Installation

bash

npm install -g @centr-ai/cli

2. Initialize Your Repository

Navigate to your project root and run centr init. CentR parses your TypeScript/JavaScript codebase using the TypeScript Compiler API and builds an in-process SQLite 3 FTS5 index in ~20-50ms.

bash

cd my-project
centr init

3. Query Context for an Agent

Ask CentR for the smallest useful piece of project intelligence needed to complete a task:

bash

centr context "Add rate limiting middleware to auth routes"

4. Incremental Syncing

As you modify files, update your index in milliseconds using SHA-256 change detection:

bash

centr sync
