dotenv-wizard

Interactive CLI to generate your .env file from a .env.example.

dotenv-wizard makes setting up environment variables for your project quick and painless. It reads your .env.example file, prompts you for each variable, and generates a ready-to-use .env file - perfect for onboarding new developers or configuring projects.

Features

• Reads .env.example automatically
• Interactive prompts for each variable
• Supports default values from .env.example
• Generates a .env file
• Optionally masks sensitive input like passwords

Installation

You can run it directly using npx:

npx dotenv-wizard

Or install globally:

npm install -g dotenv-wizard
dotenv-wizard

Usage

By default, dotenv-wizard looks for .env.example in the current directory and outputs a .env file:

npx dotenv-wizard

You can also specify custom paths:

npx dotenv-wizard --example path/to/.env.example --output path/to/.env

Options

Flag	Description	Default
-e, --example <path>	Path to .env.example file	.env.example
-o, --output <path>	Path for the generated .env file	.env

Example

Given a .env.example like:

DB_HOST=localhost
DB_USER=root
DB_PASS=

Running npx dotenv-wizard will prompt:

Enter value for DB_HOST: localhost
Enter value for DB_USER: admin
Enter value for DB_PASS: ****

And generate .env:

DB_HOST=localhost
DB_USER=admin
DB_PASS=secretpassword
