dag-rs

dag-rs (Directed Acyclic Graph) parses workspace and constructs a Directed Acyclic Graph (DAG) of local package dependencies within a monorepo or similar setups. Each edge in the graph represents a dependent → dependency relationship.

Installation

npm install dag-rs
# or
yarn add dag-rs

Note

Right now getAffectedPkg doesnt support circular dependency it might log [1] 867885 segmentation fault (core dumped) node usage.cjs

Usage

CommonJS

const { dag, getAffectedPkg } = require('dag-rs');

for (const obj of dag()) {
    console.log(obj);
}

for (const obj of getAffectedPkg("@rocket.chat/fuselage")) {
    console.log(obj);
}

ESM

import { dag, getAffectedPkg } from 'dag-rs';

for (const obj of dag()) {
  console.log(obj);
}

for (const obj of getAffectedPkg("@rocket.chat/fuselage")) {
    console.log(obj);
}

Example Output :

getAffectedPkg("@rocket.chat/fuselage") → returns all the direct , transitive dependencies

// dependents of @rocket.chat/fuselage package

@rocket.chat/layout
@rocket.chat/fuselage-toastbar
@rocket.chat/fuselage-forms
@rocket.chat/onboarding-ui

Example Output:

dag() → returns all packages in the project

// dependent : dependency
