Apify-Haystack integration

The Apify-Haystack integration allows easy interaction between the Apify platform and Haystack.

Apify is a platform for web scraping, data extraction, and web automation tasks. It provides serverless applications called Actors for different tasks, like crawling websites, and scraping Facebook, Instagram, and Google results, etc.

Haystack offers an ecosystem of tools for building, managing, and deploying search engines and LLM applications.

Installation

Apify-haystack is available at the apify-haystack PyPI package.

pip install apify-haystack

Examples

Crawl a website using Apify's Website Content Crawler and convert it to Haystack Documents

You need to have an Apify account and API token to run this example. You can start with a free account at Apify and get your API token.

In the example below, specify apify_api_token and run the script:

from dotenv import load_dotenv
from haystack import Document

from apify_haystack import ApifyDatasetFromActorCall

# Set APIFY_API_TOKEN here or load it from .env file
apify_api_token = "" or load_dotenv()

actor_id = "apify/website-content-crawler"
run_input = {
    "maxCrawlPages": 3,  # limit the number of pages to crawl
    "startUrls": [{"url": "https://haystack.deepset.ai/"}],
}


def dataset_mapping_function(dataset_item: dict) -> Document:
    return Document(content=dataset_item.get("text"), meta={"url": dataset_item.get("url")})


actor = ApifyDatasetFromActorCall(
    actor_id=actor_id, run_input=run_input, dataset_mapping_function=dataset_mapping_function
)
print(f"Calling the Apify actor {actor_id} ... crawling will take some time ...")
print("You can monitor the progress at: https://console.apify.com/actors/runs")

dataset = actor.run().get("documents")

print(f"Loaded {len(dataset)} documents from the Apify Actor {actor_id}:")
for d in dataset:
    print(d)
