ingredients

Code coverage Build Status Go Doc

This is a Golang library for ingredient tagging and extraction for any recipe on the internet. This library compartmentalizes and improves aspects of recipe extraction that I did previously with schollz/meanrecipe and schollz/extract_recipe.

Try it online: https://schollz.com/blog/ingredients/#try

Usage

Online API

You can use it online, just do GET https://ingredients.schollz.now.sh/?url=X where X is a URL to a recipe website.

$ curl https://ingredients.schollz.now.sh/?url=https://cooking.nytimes.com/recipes/12320-apple-pie
Command line

You can use it from the command line! If you download a release, you can also use it from the command line:

$ ingredients https://www.tasteofhome.com/recipes/banana-chocolate-chip-cookies/
Go library

You can use as a library.

$ go get github.com/schollz/ingredients

Pick a random website, like JoyFoodSunshine, and you can extract the ingredients:

r, _ := ingredients.NewFromURL("https://joyfoodsunshine.com/the-most-amazing-chocolate-chip-cookies/")
fmt.Println(r.IngredientList())
// Output:
// 1 cup butter (salted)
// 1 cup sugar (white)
// 1 cup brown sugar (light)
// 2 tsp vanilla (pure)
// 2 whole eggs
// 3 cups flour (all purpose)
// 1 tsp baking soda
// 1/2 tsp baking powder
// 1 tsp salt (sea)
// 2 cups chocolate chips

Please make an issue if you find a problem.

How does it work?

See my blog post about it: schollz.com/blog/ingredients.

Develop

If you modify the corpus/ information then you will need to run

$ go generate

before using the library again.
