@totemish/env

Env

Totemish ENV wraps up your NodeJS process.env and process.argv into something convenient and immutable (sort of).

Installation

npm i --save @totemish/env

Usage

Simply instantiate the Environment class and you are good to go. Features:

process.env

It automatically eats your .env file if you haven't specified NODE_ENV to be equal to production.

// NODE_ENV=production node index
import { Environment } from '@totemish/env';

const env = new Environment();

console.log(env.hasEnvKey('NODE_ENV')); // true
console.log(env.env.NODE_ENV); // 'production'

process.argv

• kwargs:

// node index --a=b --b c -c=d -d f
import { Environment } from '@totemish/env';

const env = new Environment();

console.log(env.kwargs); // { a: 'b', b: 'c', c: 'd', d: 'e' }

console.log(env.hasKwargs()); // true
console.log(env.hasKwargKey('a')); // true
console.log(env.getKwarg('b')); // 'c'

• flags:

// node index --flagged
import { Environment } from '@totemish/env';

const env = new Environment();

console.log(env.flags); // [ 'flagged' ]
console.log(env.hasFlags()); // true
console.log(env.hasFlag('flagged')); // true

• args:

// node index myArg myArg2
import { Environment } from '@totemish/env';

const env = new Environment();

console.log(env.args); // [ 'myArg', 'myArg2' ]
console.log(env.hasArgs()); // true
console.log(env.hasArg('myArg')); // true

Usage with @totemish/injector

// node index --injectionSuccess
import { Environment } from '@totemish/env';
import { Container } from '@totemish/injector';

Container.register(Environment, 'env');

console.log(Container.get('env').hasFlag('injectionSuccess')); // true
