dotenv-port

A silly little wrapper that runs your app with PORT from .env (or env vars).

🚀 Install

npm i -D dotenv-port

1. Add to scripts

In your package.json:

{
  "scripts": {
    "start": "dotenv-port next start",
    "start2": "dotenv-port node server -p .PORT.",
    "start-with-default-port": "dotenv-port node server -p .PORT:4444. "
  }
}

2. Add .env

   PORT=4030

Now:

npm run start

Next.js runs on port 4030 🎉

Tired of typing PORT=4000 npm start?
Or forgetting to add -p when running next start?

dotenv-port fixes that by:

• Reading PORT from .env (or environment)
• Setting it for your child process (process.env.PORT)
• For Next.js specifically: auto-injecting -p <PORT> into next start if you forget
