    env-var

    Small wrapper class for retrieving environment variable values.

    This module has no dependencies.

    How to install:

    npm i @alansav/env-var

    How to use:

    Create a file called index.js:

    var env = require('@alansav/env-var');
    var value = env.getValue('PORT', 3000);
    console.log('PORT: ' + value );

    execute index.js using node by using:

    PORT=8000 node index.js

    This sets an environment variable named PORT with the value of 8000 and this will output: PORT: 8000

    If you execute index using node by using:

    node index.js

    This will use the default value of 3000 since no environment variable is set and will output: PORT: 3000

    If the default value is logged then a warning will be logged to the console:

    Environment variable PORT not specified, using default value: 3000

    Install

    npm i @alansav/env-var
