isDebug

isDebug is a simple module that returns true or false upon require. If the result is true then the environment is a debug environment. if the result is false then the environment is a production environment.

isDebug looks at two environment variables to determine the result:

• NODE_ENV
  • If this environment variable begins with the string "dev" or "deb", then the result will be true
• DEBUG
  • If this environment variable is set to anything, then the result will be true

If neither environment variable are present, then the result will be false (i.e. a "production" environment).

Example

const isdebug = require('isdebug')

console.log('isdebug = %s', isdebug)

Starting the above script with DEBUG=true node script.js or NODE_ENV=development will result in:

isdebug = true

To re-check the status, e.g. to determine if process.env has been manipulated, simply re-require the module:

console.log('isdebug = %s', require('isdebug')) // false
process.env.NODE_ENV = 'development'
console.log('isdebug = %s', require('isdebug')) // true
