ecoindex_scraper 3.17.0

Ecoindex_scraper module provides a way to scrape data from given website while simulating a real web browser

Ecoindex Scraper

This module provides a simple interface to get the Ecoindex of a given webpage using module ecoindex-compute

Requirements

• Python ^3.10 with pip

Install

pip install ecoindex_scraper

If you need to convert the screenshot to webp with the generate_screenshot method, you need to install the Pillow dependency.

pip install ecoindex_scraper[webp] # OR directly pillow

Use

Get a page analysis

You can run a page analysis by calling the function get_page_analysis():

(function) get_page_analysis: (url: AnyHttpUrl, window_size: WindowSize | None = WindowSize(width=1920, height=1080), wait_before_scroll: int | None = 1, wait_after_scroll: int | None = 1) -> Coroutine[Any, Any, Result]

Example:

import asyncio
from pprint import pprint

from ecoindex.scraper import EcoindexScraper

pprint(
    asyncio.run(
        EcoindexScraper(url="http://ecoindex.fr").get_page_analysis()
    )
)

Result example:

Result(width=1920, height=1080, url=AnyHttpUrl('http://ecoindex.fr', ), size=549.253, nodes=52, requests=12, grade='A', score=90.0, ges=1.2, water=1.8, ecoindex_version='5.0.0', date=datetime.datetime(2022, 9, 12, 10, 54, 46, 773443), page_type=None)

Default behaviour: By default, the page analysis simulates:

• Window size of 1920x1080 pixels (can be set with parameter window_size)
• Wait for 1 second when page is loaded (can be set with parameter wait_before_scroll)
• Scroll to the bottom of the page (if it is possible)
• Wait for 1 second after having scrolled to the bottom of the page (can be set with parameter wait_after_scroll)

Get a page analysis and generate a screenshot

It is possible to generate a screenshot of the analyzed page by adding a ScreenShot property to the EcoindexScraper object. You have to define an id (can be a string, but it is recommended to use a unique id) and a path to the screenshot file (if the folder does not exist, it will be created).

import asyncio
from pprint import pprint
from uuid import uuid1

from ecoindex.models import ScreenShot
from ecoindex.scrap import EcoindexScraper

pprint(
    asyncio.run(
        EcoindexScraper(
            url="http://www.ecoindex.fr/",
            screenshot=ScreenShot(id=str(uuid1()), folder="./screenshots"),
        )
        .get_page_analysis()
    )
)

Async analysis

You can also run the analysis asynchronously:

import asyncio
from concurrent.futures import ThreadPoolExecutor, as_completed

from ecoindex.scrap import EcoindexScraper

def run_page_analysis(url):
    return asyncio.run(
        EcoindexScraper(url=url)
        .get_page_analysis()
    )


with ThreadPoolExecutor(max_workers=8) as executor:
    future_to_analysis = {}

    url = "https://www.ecoindex.fr"

    for i in range(10):
        future_to_analysis[
            executor.submit(
                run_page_analysis,
                url,
            )
        ] = (url)

    for future in as_completed(future_to_analysis):
        try:
            print(future.result())
        except Exception as e:
            print(e)

Get requests details from an analysis

You can get the details of the requests made by the page by calling the function get_all_requests() and also get the aggregation of requests by category by calling the function get_requests_by_category():

import asyncio
from pprint import pprint

from ecoindex.scraper import EcoindexScraper

scraper = EcoindexScraper(url="http://www.ecoindex.fr")

result = asyncio.run(scraper.get_page_analysis())
all_requests = asyncio.run(scraper.get_all_requests())
requests_by_category = asyncio.run(scraper.get_requests_by_category())

pprint([request.model_dump() for request in all_requests])
