About

This project was built on top of code written by nsafai.

What's different from the original?

• added support for the Italian language.
• added support for numbers written in words (for example six cups milk)
• added support for preposition before name of ingredient (for example six cups of milk or sei tazze di latte)

To install

npm install recipe-ingredient-parser-v3 or yarn add recipe-ingredient-parser-v3

To use

import { parse } from 'recipe-ingredient-parser-v3';

And then use on a string, for example: parse('1 teaspoon basil', 'eng'); or parse('1 grammo di zucchero', 'ita');

Will return an object:

  quantity: 1,
  unit: 'teaspoon',
  ingredient: 'basil',

  maxQty: 1
};
