Create a Scrapy Spider Project
Scrapy comes with an efficient command-line tool, called the Scrapy tool. The commands have a different set of arguments, based on their purpose. To write the Spider code, we begin by creating, a Scrapy project. Use the following, ‘startproject’ command, at the terminal –
scrapy startproject gfg_itemloaders
This command will create a folder, called ‘gfg_itemloaders’. Now, change the directory, to the same folder, as shown below –
The folder structure, of the scrapy project, is as shown below:
It has a scrapy.cfg file, which, is the project configuration file. The folder, containing this file, is called as the root directory. The directory, also has items.py, middleware.py, and other settings files, as shown below –
The spider file, for crawling, will be created inside the ‘spiders’ folder. We will mention, our Scrapy items, and, related loader logic, in the items.py file. Keep the contents of the file, as it is, for now. Using ‘genspider’ command, create a spider code file.
scrapy genspider gfg_loadbookdata “books.toscrape.com/catalogue/category/books/womens-fiction_9”
The command, at the terminal, is as shown below –
Scrapy – Item Loaders
In this article, we are going to discuss Item Loaders in Scrapy.
Scrapy is used for extracting data, using spiders, that crawl through the website. The obtained data can also be processed, in the form, of Scrapy Items. The Item Loaders play a significant role, in parsing the data, before populating the Item fields. In this article, we will learn about Item Loaders.
