deprecated-obj

Simple utility to help making the transition from deprecated configuration objects to compliant ones.

Usage

const Deprecation = require('deprecation');
 
const myConfig = {
  fine: true,
  old: {
    deprecated: true
  },
  'remove.me': 1
};
 
const deprecations = {
  old: {
    deprecated: 'new.shiny'
  },
  'remove.me': null
};
 
// Or flat:
const deprecations = { 'old.deprecated': 'new.shiny', 'remove.me': null };
 
const deprecation = new Deprecation(deprecations, myConfig);

API

Deprecation::getCompliant()

const myCompliant = deprecation.getCompliant();
→ { fine: true, new: { shiny: true } }

Returns a new, compliant object. The null values in deprecations are excluded.

Deprecation::getViolations()

const violations = deprecation.getViolations();
→ { 'old.deprecated': 'new.shiny', 'remove.me': null }

The violations can be used to inform the user about the deprecations, for example:

if (Object.keys(violations).length > 0) {
  console.warn(`Deprecated configuration options found. Please migrate before the next major release.`);
}
for (let deprecated in violations) {
  console.warn(`The "${deprecated}" option is deprecated. Please use "${violations[deprecated]}" instead.`);
}

Example

See github.com/release-it/.../deprecated.js for a real-world example.
