Frequently Asked Questions
🔧Technical Details & URL Extraction Technology
1Advanced URL Pattern Recognition
The extractor uses sophisticated regex patterns to identify and parse URLs with various protocols, handling complex edge cases and international formats with 98%+ accuracy.
Core Regex Pattern
Matches HTTP, HTTPS, FTP, File, and Mailto protocols
Captures domains, paths, query params, and fragments
Case-insensitive, finds all URL occurrences
Supported URL Types
Complex URL Support:
- • Query Parameters:
?id=123&sort=asc&filter=active - • URL Fragments:
#section-headingfor page anchors - • International Domains: IDN support for non-ASCII characters
- • Port Numbers:
:8080, :3000custom ports - • Authentication:
user:pass@host.comembedded credentials
2Intelligent URL Classification
Each extracted URL is automatically parsed and classified by type, protocol, domain, and path components using native browser APIs and fallback parsing.
Parsing Algorithm
Data Structure
{
value: "full URL string",
protocol: "https",
domain: "example.com",
path: "/path?query=1",
type: "https",
position: 142
}Special Handling for Edge Cases:
Mailto URLs:
Custom parsing removes trailing punctuation that's not part of the email address
mailto:user@example.comFallback Parsing:
If URL constructor fails, regex-based extraction provides basic protocol and domain info
3Advanced Duplicate Detection
Intelligent duplicate removal using case-insensitive comparison and Set data structures for O(1) lookup performance, even with thousands of URLs.
Algorithm Logic
url.toLowerCase()Makes comparison case-insensitive
Extremely fast duplicate checking
Maintains original order for non-duplicates
Example Scenario
Why Case-Insensitive Comparison?
- • URLs are case-insensitive for domain names (RFC 3986)
- • Different capitalizations point to the same resource
- • User expectation: Example.com and example.com are duplicates
- • Accurate statistics: Get true unique URL counts
4Multiple Sorting Strategies
Three sorting modes optimize URL organization for different analysis needs, from preserving context to grouping by source domain.
Sorting Mode Comparison
📋Appearance Order
- • Default mode
- • Preserves context from original text
- • Use case: Document analysis
- • Algorithm: Position-based
🔤Alphabetical
- • A-Z sorting
- • Easy lookup by URL string
- • Use case: Data exports
- • Algorithm: localeCompare()
🌐Domain Grouped
- • By domain name
- • Groups related URLs together
- • Use case: Site analysis
- • Algorithm: Domain sort
Performance Characteristics:
| Mode | Time Complexity | Memory | Best For |
|---|---|---|---|
| None | O(1) | Minimal | Fast, context preserved |
| Alphabetical | O(n log n) | Low | Searchability |
| Domain | O(n log n) | Low | Source analysis |
Example: Domain Sorting Benefits

5Real-Time Processing Engine
Reactive Vue.js computed properties enable instant URL extraction and processing as you type, with optimized performance for large text blocks.
Vue Reactivity System
Instant visual feedback
Only updates what changed
Smooth UI even with 1000+ URLs
Performance Metrics
Optimization Techniques:
- • Lazy evaluation: Only process URLs when options change
- • Set-based deduplication: O(1) lookups instead of O(n) scans
- • Native browser APIs: URL constructor leverages C++ performance
- • Efficient regex: Single pass with matchAll() for all URLs
- • Memory management: No intermediate arrays, direct filtering
