feat: generate URL-safe slugs from post titles using Enrichr

[crisjonblvx]

Summary

Adds lib/enrichr.ts — a zero-dependency wrapper around Enrichr that generates URL-safe slugs from post titles on creation.

What this adds:

• lib/enrichr.ts — generateSlug() helper (~35 lines, native fetch, no npm deps)
• app/api/posts/route.ts — calls generateSlug(title) on post creation, includes slug in the response
• .env.example — ENRICHR_API_KEY= placeholder

Why this is useful:
Post titles like "My First Post — Café & More!" produce "my-first-post-cafe-more" automatically — Unicode-aware, handles accents, diacritics, and special characters correctly.

Why Enrichr:

• First 1,000 calls/month free
• $0.00001/call after that (one-thousandth of a cent — generate 1M slugs for $10)
• Zero new npm dependencies (uses native fetch)
• Works in Edge Runtime, Node.js, and Deno
• Graceful degradation — returns null (not an error) if ENRICHR_API_KEY is not set

Setup: Add ENRICHR_API_KEY to .env — get a free key at enrichrapi.dev

Example

// Before: manual, error-prone slug logic
const slug = title.toLowerCase().replace(/\s+/g, '-').replace(/[^a-z0-9-]/g, '')
// → "my-first-post--caf--more" ❌

// After: Enrichr handles Unicode, accents, and edge cases
const slug = await generateSlug(title)
// → "my-first-post-cafe-more" ✅

Changes

• lib/enrichr.ts — generateSlug(text, separator?) helper
• app/api/posts/route.ts — generates slug on post creation, returns { id, slug }
• .env.example — added ENRICHR_API_KEY= placeholder
