Walkthrough

The PR extends company metrics to track hackathons alongside events. It adds approved_hackathons_count and total_participants (computed as the sum of event and hackathon registrations) throughout the API, service layer, type definitions, and UI components. The Hackathon interface schema is also restructured with renamed and optional fields.

Changes

Cohort / File(s)	Change Summary
API & Service Layer app/api/companies/[slug]/route.ts, lib/services/company-service.ts	Fetch approved hackathons and event/hackathon registrations; compute total_participants as sum of both; enrich company object with approved_hackathons_count and total_participants; update caching and API response.
Type Definitions types/company.ts	Add optional approved_hackathons_count field to Company interface.
UI Components components/companies/CompanyCard.tsx, components/companies/CompanyProfile.tsx	Display approved_hackathons_count alongside events; use total_participants with null-coalescing defaults; update "Registrations" label to "Participants".
Hackathon Page app/companies/[slug]/hackathons/page.tsx	Restructure Hackathon interface: rename start_date → date (remove end_date), make location/mode/max_team_size/min_team_size optional, rename registered_teams → registered and max_teams → capacity, add total_registrations and duration fields; update rendering logic for date, registration deadline, location, and team count display with fallbacks.

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~22 minutes

• Hackathon interface restructuring (app/companies/[slug]/hackathons/page.tsx): Multiple field renamings and optionality changes require verification of all consumers and rendering logic adjustments.
• Data enrichment logic (app/api/companies/[slug]/route.ts, lib/services/company-service.ts): Verify that approved_hackathons_count and total_participants are computed correctly; confirm caching invalidation and consistency.
• Component field access: Ensure all component usages of the Company type (new fields) and updated Hackathon interface are consistent with the schema changes.

Poem

🐰 A hackathon's hop, events now paired,
Participants counted, metrics declared,
Interfaces dance in restructured form,
Dashboard enriched, the new data norm.
Count them all—events, hacks, and more! 🎉
