Scrapy

Scrapy is a free and open-source web-crawling framework written in Python. Originally designed for web scraping, it can also be used to extract data using APIs or as a general-purpose web crawler. It is currently maintained by Zyte formerly Scrapinghub, a web-scraping development and services company. Tutorial: https://docs.scrapy.org/en/latest/intro/tutorial.html

Creating a project

scrapy startproject saavn_scraper

JioSaavn Scraper

Step 1: Scrape newly released album URLs of different languages.

scrapy crawl saavn_album_url -O saavn_albums.json

That will generate a saavn_albums.json file containing all scraped items, serialized in JSON.

Step 2: Scrape song URLs from album pages.

  • Scraper: song_url_scraper.py
  • Scraper path: saavn_scraper/spiders/
  • Spider name: saavn_song_url
  • Input URLs: album page URLS (from saavn_albums.json)
  • Output file: saavn_songs.json
scrapy crawl saavn_song_url -O saavn_songs.json

Step 3: Scrape song details from song pages.

  • Scraper: song_details_scraper.py
  • Scraper path: saavn_scraper/spiders/
  • Spider name: saavn_song_details
  • Input URLs: song page URLS (from saavn_songs.json)
  • Output file: saavn_songs_details.json
scrapy crawl saavn_song_details -O saavn_songs_details.json
