1. First, install the Scrapy framework with the following command: pip install scrapy
2. Next, add a folder and use the command prompt character to switch to the directory of that folder to create the Scrapy project, as follows: scrapy startproject any_name
3. Once you have the project, you can build a Scrapy web crawler with the following commands: scrapy genspider any_name any_name.com
4. Install scrapy-selenium following command: pip install scrapy-selenium
5. Next, go to download the browser driver for Selenium and place it in the Scrapy project folder
6. Open the settings.py file and add scrapy-selenium Middleware settings, as shown below: 
    DOWNLOADER_MIDDLEWARES = {
    'scrapy_selenium.SeleniumMiddleware': 800
   }
 
   SELENIUM_DRIVER_NAME = 'chrome'
   SELENIUM_DRIVER_EXECUTABLE_PATH = 'chromedriver.exe'
   SELENIUM_DRIVER_ARGUMENTS = ['-headless']
7. go to your spider file and write code that u want, and the code below is a sample:

import scrapy
from scrapy_selenium import SeleniumRequest


class TestSpider(scrapy.Spider):
    name = 'test'

    def start_requests(self):
        yield SeleniumRequest(url='https://www.example.com/', callback=self.parse)

    def parse(self, response):
        titles = response.xpath("//div[@class='image']").getall()  # Crawl all event titles

        for title in titles:
            print(title)  # Print the event title
