env-var 6.0.0

on Node.js NPM

• Add support for setting an example value via the example(string) function.
• Passing default values is now performed using the default(string) function.
• Defer checks for required() until an accessor such as asString() is invoked.
• Fix typings issue where required() was undefined on a IPresentVariable.

Migration from 5.x to 6.0.0 should be smooth. Change any instance of
env.get(target, default) to env.get(target).default(default). For example:

// Old 5.x code
const emailAddr = env.get('EMAIL_ADDR', 'admin@example.com').asString()

// New 6.x compatible code
const emailAddr = env.get('EMAIL_ADDR').default('admin@example.com').asString()
