lenv ⚡

“Load your .env seamlessly. Keep your shell in sync.”

lenv is a lightweight CLI tool that reads a .env file and exports all variables into your shell environment. Perfect for Node.js, React, Next.js, TypeScript projects, or any workflow where you want your environment variables loaded instantly without extra dependencies.

Features

• 🛠 Simple CLI: load .env into your current shell
• ⚡ Bash & Zsh compatible: works in any POSIX shell
• 🧩 No external dependencies: pure Node.js
• 🌐 Supports quotes & escapes: handles single/double quotes safely
• 🚀 Quick setup: eval "$(lenv)" or source env_vars.sh

Installation

npm install -g lenv
# or
yarn global add lenv
# or
pnpm add -g lenv

Basic Usage

# Load environment variables into the current shell
eval "$(lenv)"

# Or create a file to source later
lenv > env_vars.sh
source env_vars.sh

# Now the variables are available
echo $MY_VARIABLE

lenv automatically reads .env from your current working directory. You can pass a custom path as an argument: lenv /path/to/project.

Example .env

RUNTIME=SANDBOX
API_KEY="123456"
MY_SECRET='super secret'

After running eval "$(lenv)", all variables are available in your shell:

echo $RUNTIME      # SANDBOX
echo $API_KEY      # 123456
echo $MY_SECRET    # super secret

Advanced

• Quotes in values are stripped automatically.
• Single quotes are escaped for safe Bash export.
• Lines starting with # or empty lines are ignored.
