📝 WalkthroughWalkthroughThe change adds user URL parsing and user identifier extraction. Ratings and reviews scrapers validate and normalize user input before building initial and paginated request URLs. Tests cover URLs, IDs, slugs, and invalid input. ChangesUser normalization flow
Estimated code review effort: 3 (Moderate) | ~20 minutes Mergeability Score: 🟡 Moderate · up to The new user-input parsing can accept malformed or non-user URLs as user identifiers, allowing ratings or reviews requests to proceed with invalid values instead of returning the promised descriptive validation error. This bounded correctness issue should be fixed before merge. Possibly related PRs

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Reject URL-like input when it does not contain a valid user path.
Line 60 includes query or fragment text in the identifier. For example, /uzivatel/admin?tab=reviews returns admin?tab=reviews.
Line 85 returns an unparseable URL-like input as a slug. A film URL then bypasses the descriptive validation in both scraper services.
Parse the URL pathname. Return null when URL-like input does not contain /uzivatel/<identifier>. Add tests for a profile URL with a query and for a non-user URL.
Proposed fix
export const parseUserFromUrl = (url: string): string | null => {
if (!url) return null;
- const parts = url.split('/');
+ let parts: string[];
+ try {
+ parts = new URL(url, 'https://www.csfd.cz').pathname.split('/');

💡 What
Introduces
extractUserhelper allowing developers to pass fullcsfd.czURLs (or standard numeric IDs/slugs) to theuserRatingsanduserReviewsmethods. Added validation to throw clear, descriptive errors for invalid user inputs.🎯 Why
Improves Developer Experience (DX) by eliminating the need for developers to manually write parsing/boilerplate logic to extract user slugs when they only have the URL. The explicit error helps immediately diagnose invalid input instead of failing silently or mid-fetch.
