env-gen-cli

Generate .env files from templates and presets.

Installation

npm install -g @asdsadw12312dwd2112xz/env-gen-cli

Or use via npx:

npx @asdsadw12312dwd2112xz/env-gen-cli preset node

Commands

env-gen init

Interactively create a .env file from .env.example.
Secret/key variables get auto-generated secure random values.

env-gen init

env-gen init --force

env-gen preset <name>

Generate a .env file from a built-in preset.

| Preset | Description | |------------|------------------------------------| | node | Node.js app (PORT, NODE_ENV, etc.) | | docker | Docker Compose variables | | database | DB connection (host, port, name) | | auth | JWT, session, cookie secrets | | aws | AWS credentials and region |

env-gen preset node
env-gen preset database --output .env.db
env-gen preset auth --force

env-gen merge <files...>

Merge multiple .env files. Later files override earlier ones.

env-gen merge .env.base .env.local
env-gen merge .env.dev .env.prod --output .env.merged

env-gen diff <fileA> <fileB>

Compare two .env files — shows added, removed, and changed keys.
Sensitive values (SECRET, KEY, TOKEN, PASSWORD) are redacted in output.

env-gen diff .env.dev .env.prod

Options

| Flag | Description | |-------------------|--------------------------| | -o, --output | Output file path | | -f, --force | Overwrite existing file | | -V, --version | Show version | | -h, --help | Show help |

Features
