envcnf

const envcnf = require('envcnf');

Functions

• envcnf.env() - Returns your entire enviroment as an object. Same as node's process.env object. This function is here for mocking reasons.
• envcnf.get('MY_CONFIG_ENV_VAR') - Returns a string or undefined.
• envcnf.getMap('MY_CONFIG') - Returns an object containing all environment variables prefixed by MY_CONFIG_.
• envcnf.getList('MY_SERVERS') - Returns an array containing all enviroment variables prefixed by MY_SERVERS_ followed by a positive integer number, sorted in numeric order.

Mocking your configuration

When using this module, you can mock your environment variables like this:

const td = require('testdouble');

td.replace(envcnf, 'env');
td.when(envcnf.env()).thenReturn({
  'LANGUAGE': 'en_US:en',
  'MY_ENV_VAR': 'some value',
  'ETC': 'and so on...'
});

// Make your tests here...

td.reset();
