Every time you run:
npm install some-package
you are executing someone else's code on your machine.
But here’s the uncomfortable truth:
Do you really know what that code is doing?
Most don’t.
🚀 From User to Producer: How I Realized the Risk
Before I first started building npm packages, I was just a user like everyone else. Install a package, trust it works, move on.
But when you switch from user → producer, everything changes: you see how packages execute, which scripts run automatically, and the sheer power even a tiny package can hold.
Then I read about this: npm supply-chain attack happened sometime back.
A single compromised package could affect millions of machines.
💡 That’s when I thought:
“Even a small package can impact huge systems. What if we could see what it does before we install it?”
That thought sparked npm-telemetry.
⚠️ The Problem With Blind Trust
npm packages can:
- 🌐 Make network requests
- 📁 Access the file system
- 🔐 Read environment variables
- ⚙️ Spawn child processes
- 🧙 Execute dynamic code (
eval/new Function) - 📦 Run postinstall scripts
Most developers only realize this after something goes wrong. Supply-chain attacks are becoming increasingly common — and frighteningly easy.
npm-telemetry gives visibility upfront, letting you make informed decisions before installing.
🛠 Introducing npm-telemetry
npm-telemetry is a lightweight CLI and Node.js library that inspects packages and reports on their capabilities.
Think of it as a nutrition label for npm packages: you inspect, you understand, you trust consciously.
What It Detects
- 🌐 Network access
- 📁 File system read/write
- 🔐 Environment variable access
- ⚙️ Child processes
- 🧙 Dynamic execution (
eval/new Function)
- 📦 Postinstall scripts
It also calculates an analysis coverage score, so you know how thoroughly the package was inspected.
🏃♂️ Getting Started
No global installation needed. Run:
npx npm-telemetry <package_name>
Example:
npx npm-telemetry axios
Output:
🔍 Analysis Report: axios
Permissions:
🌐 Network: YES
📁 FS Read: NO
📁 FS Write: NO
🔐 Env Access: NO
⚙️ Child Process: NO
⚠ Dynamic code execution: NO
⚠ Postinstall script: null
✅ Instantly know what the package is capable of doing.
💻 Programmatic Usage
Integrate npm-telemetry into CI pipelines, dashboards, or custom scripts.
CommonJS
const analyzePackage = require("npm-telemetry");
(async () => {
const result = await analyzePackage("axios");
console.log(result.coverage);
console.log(result.report.network);
})();
ES Modules
import analyzePackage from "npm-telemetry";
const result = await analyzePackage("axios");
console.log(result.coverage);
console.log(result.report.network);
Returned object:
{
"package": "axios",
"coverage": 92,
"report": {
"fsRead": false,
"fsWrite": false,
"network": true,
"env": false,
"childProcess": false,
"usesEval": false,
"dynamicRequire": false,
"postinstall": null
}
}
🔬 How npm-telemetry Works
Under the hood:
- Scans package code for sensitive APIs
- Detects dynamic code (
eval,new Function) - Flags postinstall scripts
- Generates a coverage score
💡 No execution happens on your machine, keeping it safe.

🛡 Why This Matters
npm-telemetry:
- Makes dependency behavior visible
- Lets developers audit packages before installing
- Helps enforce security policies
- Enables custom risk scoring
Not to accuse packages, but to give developers conscious control.
💡 Philosophy
Every dependency should answer one question:
“What am I doing on your system?”
npm-telemetry provides visibility, honesty, and peace of mind.
Software shouldn’t be magic — trust should never be blind.
✅ Try It Yourself
npx npm-telemetry <package_name>
Inspect any npm package before installing it — you may be surprised at what you discover.
