Summary

Introduce a personalized job feed backend. It fetches listings from external sources (RapidAPI JSearch), caches results in Supabase with TTL, and serves role-aligned listings based on user profiles.

Details

• Add Supabase migration 004_job_feeds.sql to create job_feeds cache with TTL, RLS policies, and search function
• Implement lib/job-service.ts with cache-first fetch logic, TTL-based caching, data normalization, and cleanup
• Create API route app/api/jobs/route.ts supporting authenticated, rate-limited, query-validated, personalized job fetch and cache cleanup (POST)
• Define and export job schemas in types/jobs.ts and index.ts for centralized imports
• Document backend with docs/JOB_FEED_BACKEND.md and docs/JOB_FEED_INTEGRATION_EXAMPLE.md
• Update repository README to mention Job Feed integration
• Add environment variable example (.env.example) for RapidAPI and app URL
• Include a basic test scaffold for JobService under lib/tests/ (placeholder)
• Adjust server-side client creation pattern to call createClient per method to avoid Next.js build issues
• Add auxiliary documentation and notes for migration, security, and performance
