Package Exports

is-vegan

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (is-vegan) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

is-vegan

Is-Vegan helps you to find out which food ingredients are vegan / non-vegan. It can answer that on 1 ingredient or on a list of ingredients. It uses the 850+ entries black list of non-vegan ingredients.

How to use?

We want to make sure that you understand how is-vegan is implemented. We analyzed as many good information websites for vegan / non-vegan ingredients as we found to get a very accurate list of ingredients. However, feel free to send a pull request with an updated version of the list.
