The Web Scraper project involves developing a robust tool that enables users to extract data from various websites efficiently. The scraper will support multiple data formats and be customizable to meet user-specific requirements. This tool aims to simplify the data extraction process, making it accessible for both technical and non-technical users.
The project aims to create a user-friendly interface that allows users to define the data they want to extract, set schedules for scraping, and export the data in various formats (e.g., CSV, JSON). The solution will include features for error handling, data cleaning, and integration with other tools for further analysis.
In an increasingly data-driven world, having access to relevant information from various online sources is essential for businesses and researchers. This project will empower users to gather insights and automate data collection effortlessly. Here’s a detailed look at how users will interact with the web scraper:
User Registration and Authentication
Sign Up: Users can create an account by providing a username, email, and password. A confirmation email will be sent to verify their account.
Login: Registered users can log in using their credentials. Multi-factor authentication (MFA) will be supported for enhanced security.
Profile Management
View and Edit Profile: Users can view and edit their profile details, including contact information and preferences, to personalize their experience.
Defining Scraping Tasks
Create Scraping Job: Users can define a new scraping task by specifying the target URL, data elements to extract (e.g., product prices, article text), and scheduling options.
Customize Data Extraction: Users can set parameters for data cleaning and transformation to ensure the extracted data meets their needs.
Monitoring and Managing Scraping Jobs
Job Status: Users can view the status of their scraping jobs, including success, failure, or in-progress.
View Logs: Users can access logs for each job to troubleshoot issues and monitor performance.
Data Export
Export Options: Users can export the scraped data in various formats, such as CSV and JSON.
Integration with Tools: The scraper will support integration with third-party tools for further analysis (e.g., Google Sheets, and data visualization platforms).
Error Handling and Notifications
Error Notifications: Users will receive notifications regarding job failures or errors encountered during scraping.
Retry Mechanism: The scraper will implement a retry mechanism for failed jobs based on user-defined parameters.
Objectives
Allow users to sign up, log in, and manage their accounts.
Enable users to define and customize scraping tasks.
Provide a dashboard for monitoring and managing scraping jobs.
Ensure seamless data export in multiple formats.
Implement robust error handling and notification systems.
Functional Requirements
User Management:
Sign Up: Users can create an account by providing the necessary credentials.
Login: Users can log in to their accounts.
Profile Management: Users can update their profile information.
Scraping Task Management
Create Job: Users can set up new scraping jobs with URL and extraction parameters.
Edit Job: Users can modify existing scraping jobs.
Delete Job: Users can remove scraping jobs they no longer need.
View Job History: Users can view past jobs and their outcomes.
Data Export:
Export Data: Users can export scraped data in multiple formats.
Integration: Provide options for exporting to external tools.
Non-Functional Requirements
Scalability: The tool should handle multiple simultaneous scraping tasks efficiently.
Performance: The scraper should operate with minimal latency and be able to handle large datasets.
Security: Implement secure authentication and data protection measures.
Reliability: Ensure high availability and robust error handling for scraping tasks.
Usability: The interface should be intuitive and well-documented
Use Cases
User Sign Up and Login: New users sign up, and existing users log in.
Create and Manage Scraping Tasks: Users define and manage their scraping jobs.
Export Scraped Data: Users export the data for further use.
User Stories
As a user, I want to sign up for an account so that I can access the scraping tool.
As a user, I want to create a scraping job to extract data from a specific website.
As a user, I want to monitor the status of my scraping jobs to track their progress.
As a user, I want to export the scraped data so that I can analyze it further.
Technical Requirements
Programming Language: Select an appropriate backend language (e.g., Python, Node.js).
Database: Use a database (e.g., PostgreSQL, MongoDB) to store user profiles and job histories.
Web Scraping Framework: Implement a reliable web scraping library (e.g., Scrapy, Beautiful Soup).
API Documentation: Use tools like Swagger for API documentation.
API Endpoints
User Management
POST /signup: Register a new user.
POST /login: Authenticate a user.
