An Error is thrown if an unset environment variable is accessed.

perfect.env

Drop-in replacement for process.env that throws an Error if an unset environment variable is accessed.

const perfect = require('perfect-env')

const { PORT, CONSUMER_KEY, CONSUMER_SECRET, APP_URL } = perfect.env

instead of

const { PORT, CONSUMER_KEY, CONSUMER_SECRET, APP_URL } = process.env

if (PORT == null) throw new Error('\'PORT\' environment variable is not set.')
if (CONSUMER_KEY == null) throw new Error('\'CONSUMER_KEY\' environment variable is not set.')
if (CONSUMER_SECRET == null) throw new Error('\'CONSUMER_SECRET\' environment variable is not set.')
if (APP_URL == null) throw new Error('\'APP_URL\' environment variable is not set.')

Exception example:

Error: 'PORT' environment variable is not set.
