Why It Matters

Shipping speed depends on confidence. Teams need runtime visibility to trace impact, find architecture issues early, and ship safer changes.

• Ship Changes Faster — trace impact in minutes, not meetings, before touching critical providers or modules
• Cut Regression Risk — catch circular and high-coupling patterns before they become release blockers
• Make PR Reviews Concrete — replace assumptions with runtime-backed module and provider-level evidence
• Onboard With Real Context — give new engineers a live map of how the system actually connects and behaves
• Find Architecture Issues Early — use Issue Finder to surface structural problems before they grow into production incidents

Feature List

• Dependency Graph — visualize modules, providers, controllers, imports, and dependency edges from the running app
• Circular Detection — surface circular relationships early so teams can resolve risky loops before release
• Relation Focus — coming soon: focus provider/module pairs to see how they relate and where dependencies connect
• Context-Aware AI Assistant — ask graph and trace questions in plain language with context-aware answers, always free in the viewer
• Process Sequence — coming soon: generate sequence diagrams from an entry point to completion flow
• Direct Run — coming soon: execute runtime-resolved services and functions directly from graph context

Quick Start

npm install nest-graph-inspector 

it's not only NPM, see installation for other package manager

import { Module } from '@nestjs/common';
import { NestGraphInspectorModule } from 'nest-graph-inspector';

@Module({
  imports: [NestGraphInspectorModule],
})
export class RootModule {}
