🚀 Next-generation codebase intelligence platform for AI-powered code review, agent pipelines, onboarding, and repository analysis.

Deep Metadata Extraction • Service Interaction Graphs • Business Logic Flow Analysis • API Payload Detection • Authentication Policy Mapping

• Framework Detection (Node.js, Express, NestJS, React, Vue, Angular, etc.)
• Smart Service Classification (Business vs Utility)
• API Route & Method Extraction
• ORM Database Schema Analysis (Mongoose, Sequelize, Prisma, TypeORM)
• Utility Function Mapping by Domain
• Global Pattern Detection (Validation, State Management, Logging, etc.)
• Git Metadata Integration

• Service Interaction Graphs
• Schema Snapshots with full model field metadata
• API Payload Extraction from Joi, Celebrate, DTOs, Swagger
• Authentication Policy Mapping (JWT, Role, Middleware Chains)
• Business Logic Flow Analysis at method level
• ORM Field Metadata Extraction (with types, constraints, defaults)

• LLM-Optimized Output for AI Agents
• Fully pluggable into CI/CD or SaaS pipelines
• Modular Extractor Architecture for extensions
• Generates rich code knowledge graphs

npm install -g codebase-summary-bot # or use via npx npx codebase-summary-bot

codebase-summary-bot codebase-summary-bot --output=./summary.json --limit=50

Generates fully structured LLM-optimized metadata. Major sections:

• services: businessServices & utilityServices
• apiRoutes: publicRoutes, internalRoutes
• dbModels: ORM models and schema definitions
• utils: Utility function mappings
• frameworks: Backend, Frontend, DB, Validation libraries
• serviceDependencies: Service-to-service call graphs
• schemaSnapshots: Full ORM models with field types
• apiPayloads: Request/Response payloads per API route
• authPolicies: Per-route auth detection
• businessFlows: Business logic flow per service

• AI Code Reviewers
• Codebase Context for LLM Agents
• Architecture Quality Gates
• AI-powered Refactoring

• Instant Onboarding Docs
• Service Interaction Graphs
• API Documentation Extraction
• Code Navigation Assistance

• Continuous Architecture Analysis
• Security Audit Surface Mapping
• Microservice Boundary Extraction
• API Surface Contracts

• Business Logic Flow Visualization
• Change Impact Analysis
• Data Relationship Mapping
• Feature Planning Support

• Mongoose, Sequelize, Prisma, TypeORM

• Express.js, NestJS, Joi, Celebrate, Yup, Swagger/OpenAPI, TypeScript DTOs

• JWT, Passport.js, Custom Middleware, Express Guards

• Node.js, Express, NestJS, Koa, Fastify, Hapi

• React, Vue.js, Angular, Svelte, Next.js, Nuxt.js

• JavaScript, TypeScript

Example to run analysis in CI/CD pipeline:

name: 🤖 Codebase Intelligence on: push: branches: [main, develop] pull_request: branches: [main] jobs: analyze: runs-on: ubuntu-latest permissions: contents: read pull-requests: write steps: - name: 👅 Checkout code uses: actions/checkout@v4 with: fetch-depth: 0 - name: 📊 Generate codebase summary uses: libinvbabu/codebase-summarizer@v1 with: output-path: 'codebase-summary.json' deep-analysis: true include-flows: true - name: 📤 Upload analysis uses: actions/upload-artifact@v3 with: name: codebase-analysis path: codebase-summary.json - name: 🔍 Quality Gate Check run: |  node scripts/check-architecture-compliance.js  - name: 💬 Comment on PR if: github.event_name == 'pull_request' uses: actions/github-script@v6 with: script: |  const fs = require('fs');  const analysis = JSON.parse(fs.readFileSync('codebase-summary.json', 'utf8'));    const comment = `## 🤖 Codebase Analysis  **Services Analyzed:** ${analysis.services.businessServices.length} business, ${analysis.services.utilityServices.length} utility  **API Endpoints:** ${analysis.apiRoutes.publicRoutes.length} public, ${analysis.apiRoutes.internalRoutes.length} internal  **Database Models:** ${analysis.dbModels.length}  **Authentication Policies:** ${Object.keys(analysis.authPolicies || {}).length} routes protected`;    github.rest.issues.createComment({  issue_number: context.issue.number,  owner: context.repo.owner,  repo: context.repo.repo,  body: comment  });
