recipe-scraper

A recipe scraping library which makes it easy to scrape recipes from popular sites around the web.

Current site support is still limited. A full list is available in SITE-SUPPORT.md.

Requirements

Composer, PHP 7.0 or later.

Installation

composer require ssnepenthe/recipe-scraper

Usage

Scraper instances work on Symfony DomCrawler instances. These can be created however you choose, but the easiest is to use a BrowserKit implementation like Goutte:

$client = new Goutte\Client;
$crawler = $client->request('GET', 'http://allrecipes.com/recipe/139917/joses-shrimp-ceviche/');

If you only need to scrape recipes from a single site, you can use the corresponding class from src/Scrapers:

$scraper = new RecipeScraper\Scrapers\AllRecipesCom;

If you want to be able to scrape recipes from all supported sites, create a DelegatingScraper using the Factory class:

$scraper = RecipeScraper\Factory::make();

Check whether a scraper supports a given crawler using the ->supports() method:

$scraper->supports($crawler); // true

Finally, scrape a recipe by passing the crawler to the ->scrape() method:

$recipe = $scraper->scrape($crawler);

The following properties are guaranteed to be set on the $recipe array:

$recipe['author'] // string|null
$recipe['categories'] // string[]|null
$recipe['cookingMethod'] // string|null
$recipe['cookTime'] // string|null
$recipe['cuisines'] // string[]|null
$recipe['description'] // string|null
$recipe['image'] // string|null
$recipe['ingredients'] // string[]|null
$recipe['instructions'] // string[]|null
$recipe['name'] // string|null
$recipe['notes'] // string[]|null
$recipe['prepTime'] // string|null
$recipe['publisher'] // string|null
$recipe['totalTime'] // string|null
$recipe['url'] // string|null
$recipe['yield'] // string|null

If the ->scrape() method is called on an unsupported crawler instance, all values in $recipe will be null.

Altogether:

$scraper = RecipeScraper\Factory::make();
$client = new Goutte\Client;
$url = 'http://allrecipes.com/recipe/139917/joses-shrimp-ceviche/';
$crawler = $client->request('GET', $url);

if ($scraper->supports($crawler)) {
    var_dump($scraper->scrape($crawler));
} else {
    var_dump("{$url} not currently supported!");
}

Limitations

Scraping seems to be (unfortunately) the best option available for extracting structured recipes from the sites supported by this scraper.

Just keep in mind that any template updates to the target site have a very high chance of breaking this scraper.

If you notice support for a particular site is broken, please submit an issue or pull request.

For this same reason, it may be preferable to track the master branch of this repo, although I will try to tag a new release after any site-specific updates.
