strict-env-validator

I kept breaking apps because of missing env variables… so I built this.

Hey everyone 👋

I’ve lost count of how many times this happened:

• App crashes in production
• Turns out → missing or invalid .env variable
• Or worse… typo like DATABSE_URL 😅

So I built a small utility to fix this problem:

👉 strict-env-validator

🔗 https://www.npmjs.com/package/strict-env-validator

🔧 What it does

• Automatically loads .env files
• Validates all environment variables at startup
• Throws clear errors if something is missing or invalid
• Prevents your app from running with bad config

✨ Why I built it

I tried existing tools, but I wanted something:

• Simpler to use
• Strict by default
• Works out of the box without too much setup

Most tools validate env variables, but I wanted something that fails fast and clearly before your app even starts.

⚡ Example

Instead of writing validation manually:

const PORT = process.env.PORT;
if (!PORT) throw new Error("Missing PORT");

You get:

import "strict-env-validator";

And it handles everything for you ✅

🎯 Goal

Make .env handling:

• predictable
• safe
• impossible to mess up

🙌 Feedback

This is still early, so I’d really appreciate:

• feedback
• feature ideas
• criticism

If you’ve faced similar issues, I’d love to hear how you handle env validation.

Thanks!
