Yargs command for managing environment files

Install

1. Install Node.js
2. Install yargs-command-env via npm

npm install --save yargs-command-env

For the latest developer version, see Developer Install.

Usage

Create a file named bin.js with the following contents:

var yargs = require('yargs');

// (env) Load command with path to env file
// Replace './path/to/.env' with your .env file
var env = require('yargs-command-env')({file: './path/to/.env'});

// (yargs) Add command to manage env file
var argv = yargs.command(env).argv;

Display help options for bin.js using node:

node bin.js env help

The following will be displayed:

bin env <task> [key] [value] [--env]

manage default env

<task> is one of:

* set
* delete
* view
* clear
* reset

Set variable to value
> set [key] [value]

Remove default variable
> delete [key]

View default variable
> view

Clear default variable
> clear

Reset default variable
> reset

Manage other env file
> set [key] [value] --env other.env
> delete [key] --env other.env
> view --env other.env
> clear --env other.env
> reset --env other.env

Default env files are managed with the commands below:

node bin.js env view
node bin.js env clear
node bin.js env reset
node bin.js env set key value
node bin.js env delete key

Other env files are managed by passing a path in the option --env:

node bin.js env view --env .env
node bin.js env clear --env .env
node bin.js env reset --env .env
node bin.js env set key value --env .env
node bin.js env delete key --env .env
