Active Inflector is a library for inflecting words between plural and singular forms. Active Inflector aims to be compatible with ActiveSupport::Inflector from Ruby on Rails, including the ability to add your own inflections in your app.

Requirements:

• ESM
• Private Fields

As always, a consuming project can run a transpiler over dependencies.

pnpm add active-inflector

All methods are always available from the active-inflector module:

import { Inflector, singularize, pluralize } from "active-inflector";

Inflector.inflector.singularize("tacos"); // taco
Inflector.inflector.pluralize("taco"); // tacos

singularize("tacos"); // taco
pluralize("taco"); // tacos

pluralize(2, "taco"); // 2 tacos
pluralize(2, "tacos", { withoutCount: true }); // tacos

If necessary you can setup special inflection rules for your application:

import { Inflector } from "active-inflector";

Inflector.inflector.irregular("person", "people");
Inflector.inflector.uncountable("sheep");
