library0.1.0jsnpmunverified

Active Inflector is a JavaScript/TypeScript library for pluralizing and singularizing words, aiming for full compatibility with Ruby on Rails' ActiveSupport::Inflector. Version 0.1.0 is the latest stable release, with infrequent updates. It provides both default export of an Inflector class with static methods and convenient standalone singularize/pluralize functions. Key differentiators: Rails-compatible custom rules (irregular, uncountable, uncountable), supports numeric pluralization (e.g., pluralize(2, 'taco') → '2 tacos'), and ships TypeScript types. Requires ESM and environment support for JS private fields.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

Inflector

✓ import { Inflector } from 'active-inflector'

✗ const Inflector = require('active-inflector')

Package is ESM-only; CJS require() will fail.

singularize

✓ import { singularize } from 'active-inflector'

✗ import singularize from 'active-inflector/singularize'

Singularize is a named export, not a default export from a subpath.

pluralize

✓ import { pluralize } from 'active-inflector'

Pluralize supports both string and numeric overloading; e.g., pluralize(2, 'taco').

Demonstrates basic singularize/pluralize, numeric pluralization, and custom irregular/uncountable rules.

import { Inflector, singularize, pluralize } from 'active-inflector'; // Basic singularization/pluralization console.log(singularize('tacos')); // 'taco' console.log(pluralize('taco')); // 'tacos' // Numeric pluralization console.log(pluralize(2, 'taco')); // '2 tacos' console.log(pluralize(2, 'tacos', { withoutCount: true })); // 'tacos' // Custom irregular and uncountable rules Inflector.inflector.irregular('person', 'people'); Inflector.inflector.uncountable('sheep'); console.log(pluralize('person')); // 'people' console.log(pluralize('sheep')); // 'sheep'

Debug

Known issues

breakingPackage is ESM-only. CJS require() causes runtime error 'ERR_REQUIRE_ESM'.

fix

Use dynamic import() or switch to ESM in your project.

affects: >=0.0.1

gotchaInflector.inflector.singularize() vs singularize() directly: both work, but the static method via Inflector.inflector is the only way to access custom rules after they are set.

fix

Use Inflector.inflector.singularize() when you need custom rules to apply, otherwise standalone singularize() is fine.

affects: >=0.0.1

gotchaNumeric pluralize overload expects count as first argument. Passing a string number will not work correctly.

fix

Ensure the first argument is a number, not a string. E.g., pluralize(2, 'taco') not pluralize('2', 'taco').

affects: >=0.0.1

breakingRequires JavaScript environment that supports private class fields (e.g., Node.js 12+, modern browsers). Running in older environments may throw SyntaxError.

fix

Transpile with Babel/TypeScript targeting older environments, or use a polyfill for private fields.

affects: >=0.0.1

deprecatedPackage is very early (v0.1.0); API may change without major version bump.

fix

Pin to exact version and monitor releases.

affects: >=0.0.1

Errors

Common errors & fixes

ERR_REQUIRE_ESM

Trying to require() an ESM-only package.

fix

Use import { Inflector } from 'active-inflector' or dynamic import().

TypeError: Inflector.inflector is undefined

Using default import instead of named import Inflector class.

fix

Ensure import is correct: import { Inflector } from 'active-inflector'. The Inflector class is exported as a named export, not default.

SyntaxError: Unexpected private field

Environment does not support JavaScript private class fields (# syntax).

fix

Use a transpiler like Babel with @babel/plugin-proposal-private-methods or target a newer runtime (Node >=12, modern browsers).
